Our verdict

LG C4 is a television that will likely have no competition in its price range for many users. Thanks to the wide options for purchase, it will appeal to those looking for a TV strictly for movies and series, as well as for gaming. The advanced WebOS system and a remote that works like a mouse will certainly make everyday use much easier and ensure that we will likely stick with this brand for a much longer time. The OLED panel implemented by the manufacturer, resulting from over 10 years of history, shows that it has not yet said its last word. Brightness results in HDR material are very solid and can display an incredibly dynamic and deep image. Here, it’s worth mentioning the excellently implemented dynamic tone mapping feature, which makes HDR10 images look almost as good as Dolby Vision. And if we’re talking about fidelity to artistic vision, we can't forget about how calibratable LG TVs are, allowing for a great deal of freedom for the calibrator and classic calibration for home users, as well as 3D LUT for professionals. However, if we are looking for a gaming TV, then the LG C4, like most of the manufacturer’s OLED TVs, will be the ideal choice. With the implementation of HDMI 2.1 ports and the full use of their potential, we can enjoy extremely smooth gameplay with all the benefits, such as VRR, ALLM, FreeSync, or G-Sync. Of course, the panel, which has a maximum refresh rate of 144 Hz and an advanced smoothing technology, will also allow for very smooth and sharp images during broadcasts of various sporting events. It’s hard not to give a high rating to LG OLED C4, as it's difficult to find a TV in a similar price range with such advanced features among the competition.

Philips OLED770 is a television that stands out primarily for its picture quality – the characteristic perfect black and infinite contrast typical of OLEDs make even a regular evening of binge-watching a series feel like a small cinematic experience. After calibration, the colours gain naturalness and consistency, while details in dark scenes are separated from the lights with surgical precision. This is a screen that gives the feeling of engaging with premium-class technology, even though it is formally a budget OLED in Philips' portfolio. The second pillar on which the OLED770 stands very strong is gaming. Here, the manufacturer has really done their homework. VRR works up to 120 Hz, we have an automatic game mode (ALLM), and input lag in standard HDR10 or SDR modes at 120 Hz can drop to as low as 5 ms – these are results that will easily satisfy even the most demanding gamers. And finally, the Ambilight system – for many it’s a gadget, but during longer sessions, it truly makes a difference. The colourful LEDs behind the screen dynamically respond to what's happening in the game, and can pull you deeper into the virtual world. It’s precisely for this reason that one could risk saying that the OLED770 is one of the more interesting budget gaming TVs on the market.

However, not everything shines so brightly, because when we come to the Smart TV aspect… TitanOS is the biggest drawback of this model. Theoretically, we have everything we need: access to apps, AirPlay support, and voice commands. In practice, though, the list of apps is limited, screen mirroring often doesn’t work at all, and voice search does not support the Polish language. Moreover, the remote, although well-designed and backlit – operates on infrared, which sounds almost anachronistic in 2025. The system is purportedly fast, but it can irritate with errors, and instead of encouraging usage, at times, it rather urges us to turn it off. And here we reach the crux: the OLED770 is a television that performs excellently as a screen for movies and games, but not necessarily as a multimedia hub for the home. For someone who mainly uses a console, home cinema, or operator's decoder – it will be a solid choice. We get fantastic picture quality, a full set of modern gaming features, and of course, the proprietary AmbilightTV backlighting system! But if someone is looking for a television that has to replace everything and serve as a multimedia powerhouse, it would be better to look towards the more expensive Philips models that offer more refined system solutions like GoogleTV.

LG OLED C4, as the name suggests, uses an organic panel of its own production. This series definitely belongs to one of the most recognisable on the market. Over 10 years of experience in building self-emissive panels has allowed for the refinement of each subsequent design, with the models from the 2024 range being the quintessence of this process. Of course, the use of this type of screen enables the achievement of flawless contrast and blacks, allowing viewers to immerse themselves in the world created by the director. This is possible thanks to the OLED panel, characterised by the absence of conventional backlighting, which instead allows current to pass through organic pixels. This permits super-accurate image control, thereby eliminating issues such as dimming of delicate fine details or the halo/blooming effect. Looking at both of our test scenes, we can notice two things: perfect light separation and a plethora of details in the movie "Sicario 2".

In terms of black and contrast, the Philips OLED770 doesn’t introduce any revolutions – but with OLEDs, it would be hard to expect one. The organic matrix allows for complete blacking out of individual pixels, which in practice gives us almost perfect black and contrast that reaches infinity. Whether we’re watching night scenes in films or scenes full of tiny bright points, the TV precisely separates details from the background. There are no halo effects or other artifacts typical for LCD TVs with local dimming here. Choosing an OLED – also in the version of model 770 – you can be assured that in this category, the image will look fantastic.

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

The Philips OLED770 doesn't try to compete with the brightest OLEDs on the market, and it's actually hard to expect that, as it's the entry-level model in Philips' range for 2025. In our measurements, it reached a maximum of around 700 nits, which allows for enjoyment of HDR effects in scenes where light appears in spots – for instance, in the flash of headlights or a starry sky. In such moments, the picture can truly amaze. However, it's different when there are more bright elements on the screen. The TV, like many cheaper OLEDs, restricts luminance at that point, and the entire image noticeably dims. This was best seen in a scene from the movie The Meg, where the sun rises behind an oil platform – the brightness dropped to around 250 nits, which is almost three times less. The HDR effect remains pleasing to the eye, but it's worth being aware that this model performs best in scenes with less intense light. Fortunately, the OLED770 also has an ace up its sleeve – the coverage of the DCI-P3 colour palette is as high as 99%, so colours in movies and games are vibrant and very close to what the creator intended.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

The first measurements already show that the factory settings of the Philips OLED770 have a lot to improve, even in Filmmaker mode. The white balance chart clearly indicates a lack of blue, giving the image a slightly yellowish tint. In practice, white is not snow-like, but leans towards warmer hues – which some may even find appealing, but from a precision standpoint, this is a deviation from the norm. The gamma, on the other hand, tends to be on the darker side – the average value is around 2.6 instead of the reference 2.4. In mid-tones, the image appears muted and more saturated, which can look too "cinematic" but detracts a bit from the naturalness. However, the most significant issues are visible in colour reproduction. The average error is relatively high, and some colours – particularly shades of grey – deviate significantly from what should be seen. In everyday viewing, this means that sometimes colours may look less natural than we would wish.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

Philips OLED770 had shown signs from the start that it harboured significant potential, but it was hard to fully appreciate this in its factory settings. The image was often too warm, and some colours appeared as if they had lost their naturalness along the way. Calibration revealed that this television was very amenable to work – it responded to every adjustment and almost immediately unveiled another layer of its capabilities. The white balance was set in both SDR and HDR so that the yellowish haze disappeared and a neutral, clear white emerged. Gamma stabilised closer to perfection, which helped restore the naturalness of mid-tones, while shadows ceased to be artificially darkened, perhaps even with a slight brightening effect. The result was obvious... Movies are watched with greater ease; the image has cinematic depth without the feeling that something is overly darkened. However, the most interesting aspect was working on the colours. Factory errors were not dramatic, but slightly noticeable – skin tones could be too warm, and grey wasn’t always the shade we expected. After calibration, the error values dropped to around 2, and in many cases even below 1. This is a level that is definitely lower than the threshold of discernibility for the human eye. In other words, after correction, the colours finally “clicked” into place. Looking at the screen, we felt like the television had begun to speak with a full voice. Like an instrument that had finally been properly tuned.

The fluidity of tonal transitions in LG televisions has always been a rather sensitive issue, as the manufacturer, despite impeccable performance in other areas, has almost always struggled to get this right. The evaluation results for the fluidity of tonal transitions in the tested television were quite good, with issues mainly visible in darker scenes, such as the last two scenes. Interestingly, this is a significantly better result than the highest model from the manufacturer, namely the LG G4.

In this category, there’s a noticeable improvement compared to last year's Philips models. The OLED770 handles colour gradation significantly better, and strongly visible transitions or artificial banding occur less frequently than before. Interestingly, we achieved the best results in dark scenes – where most televisions, especially those with WOLED panels, tend to struggle the most. A good example is the shot of an actor floating in red water – the transition from intense red to black looks nearly perfect here, without the typical “stair steps.” The situation is somewhat worse in light parts of the image. With extremely bright gradients, particularly close to white, the television has trouble maintaining smoothness. This can be noticed, for example, in a scene from the film Kingsman, where in the background of the bright sky with the sun, subtle bands of the sunrise appear instead of a smooth blur. Fortunately, these situations are relatively rare, and in everyday viewing, the OLED770 presents itself very solidly and doesn’t disrupt immersion as was the case in last year's models.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on LG C4 is quite good, however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

The problem of the previously mentioned colour connections can largely be mitigated thanks to the "distortion reduction" function, which is an algorithm for smoothing tonal transitions in Philips. It works best at a low level – effectively eliminating unwanted colour bands while not introducing strange artifacts or losing image detail. This is one of those features that is truly worth keeping on.

The issue of upscaling is somewhat less impressive. Images from lower resolution can be too soft, while in some parts the characteristic "jaggies" appear. The impression is that the algorithm is trying to reconcile two contradictory directions – smoothing and sharpening – and ultimately fails to find the golden mean. As a consolation, it's worth noting that the television does not have problems with overscan, meaning it does not cut off the edges of the image, which can sometimes happen in other competing models.

The maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those who require high fluidity of the image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

The issue of the panel in the Philips OLED770 is not entirely straightforward. The manufacturer claims a 120 Hz panel, but our measurements showed that the screen can accept a 4K signal even at 144 Hz. This sounds like great news – because who wouldn't want an additional mode for PC gamers at this price? However, the reality turned out to be more complex. With 120 Hz content, the television behaves like most OLEDs – the image is absolutely clear, with no trace of blurring or smearing, ideal for both dynamic games and sports broadcasts. The problem only arises at 144 Hz. Unlike models with official support for this frequency, here we see the phenomenon of so-called frame skipping. This means that the television is unable to display all the frames – some of them are skipped, causing motion to lose smoothness and double outlines to appear on the screen. The effect resembles the operation of the BFI function, which Philips does not offer in this model anyway.

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and television.

In summary: LG C4, just like all the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.

If someone is looking for a TV for gaming, the Philips OLED770 is a candidate that's hard to overlook. The mere fact that this is an OLED gives it a great starting point – perfect blacks and infinite contrast make evening sessions in atmospheric games look like they've been taken straight out of a cinema. Added to that is the Ambilight system, which uses LEDs on the back of the TV to extend the image onto the wall behind the screen. The effect is such that even just playing FIFA can look like a small spectacle, and in horror games, the atmosphere becomes really thick. On the technical side, it's also quite decent. The Philips OLED770 supports variable refresh rate (VRR) up to 120 Hz, has an automatic mode for gamers (ALLM), and for those using an Xbox Series X, Dolby Vision support in games is also available. You just need to know that in this mode, the input lag is slightly higher than standard, although still at an acceptable level. As a bonus, we also get the 'Game Bar', which is a special tool strip for gamers. It's not the most conveniently designed solution, but it allows for a quick view of key parameters without exiting the game. Overall, this gives a picture of a TV that has all the most important gaming features on one hand, and on the other can add something unique – Ambilight. And it's this mix of technology and visual effect that makes the OLED770 one of the better screens for gaming in a home environment.

The latency time of LG C4 is remarkably low in every scenario. Even the most avid gamers will surely appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, which is only 5 ms. It's also worth noting that the lag at these same settings, but with Dolby Vision HDR enabled, remains unchanged, which is not so obvious with the competition. Therefore, it deserves the highest rating and recommendation.

As we mentioned earlier, the only anomaly that has been captured during testing is the Dolby Vision Gaming mode. In this setting, the latency can reach up to 30 ms. This is not a particularly impressive result, and more demanding players may turn up their noses, but in practice – during casual sessions – the difference will not be greatly noticeable. The standard HDR10 and SDR modes perform much better, however. In the case of a 120 Hz signal, the input lag drops to a minimal 5 ms, which is an outstanding result and places the OLED770 among the top TVs suitable for dynamic gaming. In other words, if someone isn’t set on Dolby Vision on Xbox, the gaming experience will be fast, smooth, and free of unnecessary delays!

LG C4 combined with a PC works wonderfully, thanks to its very low latency of just 13.5 ms, which is practically instantaneous feedback between the mouse, eye, and screen. An extremely important aspect when working on a screen is the readability of text, which in the case of the tested TV is very good. However, it is worth noting that to achieve sharp fonts, you need to enable the passthrough option in the settings.

The RWBG pixel layout does not significantly affect the display of fonts or letters, which is a significant advantage over Samsung's QD-OLED panels. Users of both Windows-based PCs and macOS will surely be pleased with their experience on the tested TV screen.

Philips has learned from previous models and has finally improved the implementation of chroma 4:4:4. This is important news for those planning to connect the TV to a computer, as it means no problems with sharpness and readability of fonts. Text looks clear and crisp, so the OLED770 can easily be called an excellent display for office work or browsing the internet. Of course, very demanding users may notice some imperfections resulting from the WRGB pixel arrangement typical of WOLED panels, but in practice, this does not significantly impact comfort. The TV also performs well in games launched from a PC. The panel allows for real refresh rates of up to 120 Hz, and with low input lag, this provides a very smooth image without noticeable stutters. The only thing missing is support for G-Sync and – as we mentioned before – a proper 144 Hz mode, but despite that, the overall performance is really solid. For those looking for a versatile screen for computer and console use, the OLED770 is a choice that’s hard to underestimate.

The undisputed advantage of OLED panels is their efficiency in the context of group viewing, meaning from various angles. LG C4 maintains very good contrast, colour saturation, and fidelity. Although this isn't a result of organic TVs supported by MLA technology, it's fair to say that anyone who purchased the device was satisfied with the results obtained. However, it should be noted that at sharp angles a slight greenish tint can be observed. This is a characteristic feature of WRGB panels from LG, without the aforementioned micro-lens technology, and unfortunately, there's nothing that can be done about it.

In terms of viewing angles, the Philips OLED770 presents a very high level typical of OLEDs. The image remains readable and saturated even when viewing the screen from the side – there is practically no drop in contrast or fading of colours. In this category, it only falls short of QD-OLED panels, which we find either in very expensive premium models or in one exceptional case – in the 55-inch Samsung S85F. However, in everyday use, the differences are difficult to detect, and the OLED770 performs nearly perfectly. Only at really extreme angles can a slight degradation of colours be noticed.

Matrix brightness

Average luminance SDR

Philips OLED770: 249 cd/m2

LG OLED C4: 367 cd/m2

The maximum brightness of the television in SDR materials is 367 nits. For an OLED television, this is a very good result and allows for quite comfortable viewing during the day. It's worth noting two things. Thanks to the glossy coating of the panel, the light reflections are well held in place and do not spill over the rest of the panel. The second issue is the brightness of the screen when fully filled with white, oscillating around 220 nits, which is a remarkable result, as until recently, OLED televisions in this category could only boast brightness half as much. As a result, the conditions for watching, for example, winter sports will be very good.

OLED770 is not one of the brightest TVs, so it's hard to recommend it for very sun-filled living rooms. In a bright room, its limitations quickly become apparent – the screen catches reflections and behaves more like a lightly dimmed mirror. Glare reduction is average, and in direct light, the screen performs poorly. Fortunately, the panel's coating does not distort colours, so even during the day, the hues remain natural, and the blacks do not dramatically lose their depth. Nevertheless, it’s hard to say that the OLED770 is a TV designed for bright spaces – it will definitely find a better home in a dimly lit living room or in a bedroom, where its strengths can truly shine.

LG uses the well-known proprietary WebOS system that has been around for many years. The system offers virtually all the major apps, and the few that are missing can be counted on one hand, such as CDA or KODI. It's also worth noting that the modern web browser and the remote with a built-in mouse allow for convenient access to streaming services in this way, if there isn't a built-in app.

WebOS also features a highly praised ability to perform operations using a cursor that appears when the remote is moved. The convenience of this function is invaluable when entering queries or passwords for portals. WebOS, like most systems, also supports features such as screen mirroring, AirPlay, voice searching in Polish, and the ability to connect headphones via Bluetooth. On a more practical note, WebOS allows simultaneous use of headphones and the television speaker, which will certainly be a significant help for those with hearing impairments. One of the more interesting features, particularly appreciated by sports fans, is the ability to turn on an alert for an upcoming match, ensuring that we never miss a broadcast. The home panel also deserves praise, allowing for control of all smart devices connected to the home network. For example, the end of a wash cycle will be signalled by a notification in the top right corner.

In summary, the WebOS system, although less known and with certain limitations compared to Android TV, offers stable and quick performance and supports most functions that users may need. It is a solid solution for those looking for a simple and effective operating system in their television.

Functional Features

Let's start with the basics, which are the classic functions of a television. The Philips OLED770 doesn’t turn the table here; we have a standard EPG interface, the ability to connect devices via Bluetooth, and a few simple configuration options including teletext. Interestingly, there is a jack connection, which is becoming quite rare these days. However, those with older receivers or wired headphones will appreciate it. The remote creates a good impression – it’s ergonomic and has a backlit numeric keypad – but there’s also a sense of a step back here. It works via infrared, so you have to aim it at the television, and frankly, by 2025 we would expect full wireless support. The exception is voice commands, which use Bluetooth, but even here there’s no reason for euphoria.

SmartTV Features – TitanOS

Speaking of voice, let’s move on to the Smart TV system, which is an element that largely defines the daily comfort of using a television today. And here the OLED770 clearly lags behind the competition. TitanOS operates quickly enough that it's not a disaster, but daily use can be frustrating due to minor bugs and shortcomings. Theoretically, we get support for AirPlay, but on the other hand, screen mirroring just didn’t work at all in practice. Voice search? Yes, but only through Amazon Alexa and without support for the Polish language. In other words, the features are there, but when we try to use them, we find that their practicality is severely limited and nearly useless. And it’s this Smart TV aspect that becomes the greatest hindrance of the OLED770. The image can be astonishing, gaming is excellent, and Ambilight creates a unique atmosphere – but when we transition to daily use of apps and services, we feel a sense of dissatisfaction.

Ambilight – Philips OLED770

Although in terms of smart functionality, the Philips OLED770 is rather average, it has something in store that its competitors honestly envy. We’re talking about the three-sided Ambilight system, which has been a hallmark of this brand’s televisions for years. The LED lights positioned at the back of the housing dynamically illuminate the wall in colours matched to whatever is happening on the screen at that moment. The effect is simple but very suggestive – the image seems to extend beyond the boundaries of the television, giving us the impression that the screen has suddenly grown by extra inches. During a movie screening, it can create atmosphere, in games it enhances immersion, and during regular TV viewing, it simply pleases the eye. It’s this addition that makes it so that despite the limitations of TitanOS, the OLED770 has something that can attract attention and give it character.

The default file player on LG C4 handles all photo resolutions exceptionally well. It successfully plays videos recorded in practically all the most popular formats, including Dolby Vision. The only codec that the C4 won't play is H.266 VVC, although this is currently rather uncommon. It's a pity that subtitles in .txt format are not supported. Attention should be paid to the supported photo formats, of which there are only three: JPEG, PNG, and, importantly for Apple phone users - HEIC. However, the tested television cannot be faulted for a lack of variety in audio files, which can be played without a compatibility warning.

The built-in media player in the Philips OLED770 works quite well, especially when it comes to subtitles – virtually every format we threw at it was handled correctly, which will certainly please those watching films from their own library. However, there are certain reservations regarding photo support. Not all resolutions are recognised, which may surprise users accustomed to viewing photographs from traditional cameras or older memory cards. Apart from that, everything works correctly – it’s just worth ensuring that the TV can handle the files that we actually want to play on it.

The audio system implemented in LG C4 is very well tuned, allowing us to experience strong bass as well as balanced mid and high tones. We can confidently say that in its price range, it's one of the better sounding televisions. However, we believe that those deciding to purchase the C4 will already have a dedicated audio set. The presence of DTS-HD Master Audio and Dolby Atmos codecs will also be significant.

When it comes to sound, the Philips OLED770 performs quite well, although you can't expect powerful bass. For regular TV viewing, streaming services or series, its capabilities are more than sufficient – dialogues are clear, and the overall tonal balance is at a decent level. However, when we want to feel a real punch in cinematic productions or games, it quickly becomes apparent that it lacks solid low-end response. In such a situation, a natural complement becomes an additional soundbar or audio system that will allow you to take advantage of the potential of the excellent picture.

On the plus side, versatility in handling formats must be noted. The OLED770 can manage practically all popular codecs, including Dolby Atmos, DTS:X, and Dolby TrueHD. Because of this, when connecting external audio equipment, you can expect a full sound experience, even if the built-in speakers in the TV don't make a spectacular impression.
