SONY BRAVIA 3 vs LG MRGB85B

Bravia 3 does not hide the fact that it belongs to a group of TVs that are rather modest in terms of brightness. Our measurements showed around 370 nits, which is a value balancing on the brink where any HDR effect can still be discussed. For some, this is an acceptable level, while for others it is more typical for SDR materials, where spectacular flashes or vivid contrasts are not expected. The impression is that this is not a TV for those focused on the highest image quality in demanding film content. However, this does not mean that there are no advantages to be found here. Compared to its predecessor, the X75WL, the Bravia 3 has gained an additional PFS filter, which works similarly to solutions known from QLED technology. Thanks to this, the DCI-P3 color gamut has been significantly expanded, reaching over 91 percent, which in practice results in more saturated colours and a more pleasing texture of the image. As a result, even everyday content looks a bit more vibrant, and films and series can surprise with their colourful presentation, despite limitations in brightness itself.

LG MRGB85 offers moderate brightness. On test patterns it reaches around 700 nits, which is a decent result in itself. In real movie scenes, however, values are lower and most often fall in the 400 to 600 nits range. Bright, wide shots look best. In scenes with large areas of black the TV noticeably reduces luminance, attempting to keep contrast as high as possible. The HDR effect is therefore visible, but it is far from the level offered by more advanced Mini-LED designs. Particularly in darker parts of films, the limitations of the edge-lit backlight and imprecise local dimming become apparent again.

HDR colours

A much stronger suit of the MRGB85 is its colour. The TV covers around 95% of the DCI-P3 colour space and 74% of BT.2020, so HDR content can look vivid and impressive. Colours are well saturated, and the difference compared with basic LCD TVs is clearly noticeable. It is worth noting, however, that this is not a classic RGB backlight, where each of the three primary colours is generated by a separate diode. Red is produced by a PFS phosphor, which expands the palette and achieves more saturated red tones. This solution performs well for colour reproduction, but it does not change the limitations of the local dimming. The diodes are not driven independently in the way the series name might suggest... so it turns out that Mini RGB is not the same as Mini-LED RGB!

We primarily tested the Sony Bravia 3 in movie mode, which immediately turned out to be the best choice among the factory settings. It's not a perfect picture, but compared to the eco mode that the TV suggests straight out of the box, the difference is evident and definitely better. In movie mode, there is a noticeable issue: the picture seems too warm, which is due to the lack of blue colour in the white balance. Nevertheless, in SDR content, the final effect can still be considered quite decent and satisfactory for everyday viewing. Much more serious errors arise in HDR materials. The Color Checker analysis showed significant deviations, and poor brightness management, combined with limited colour gamut coverage, further exposes the shortcomings of the picture in this mode. All of this makes HDR on the Bravia 3 look unconvincing and can ruin the impression left by the otherwise quite decent SDR content settings. Fortunately, it’s not a hopeless situation. Various errors can be somewhat mitigated, and some can even be completely corrected through professional calibration. That's why we decided to check how the TV would perform after such adjustments.

We tested the TV in Filmmaker Mode because, of the available presets, it produced the image closest to reference. The out-of-the-box colour reproduction wasn’t perfect, though. The biggest deviations were in the white balance, with too much red and not enough blue in the image, so the overall picture shifted noticeably towards warmer tones. Whites took on a slightly yellowish tint, and skin tones and bright areas didn’t always look natural. It wasn’t a fault that ruined the viewing experience, but in a direct comparison with the same panel after calibration the difference was clearly visible.

Calibration allowed us to extract significantly more from ChooseTV 3 than we could have expected at the beginning. First and foremost, it managed to address the deficiency of blue, which previously caused a noticeable warming of the image. After a slight adjustment in white balance, most errors in the Color Checker measurements for SDR content practically disappeared. The whites took on a natural tone, and brightness management in gamma stabilised to an almost ideal level, not exceeding the threshold of what the human eye can perceive. So it is safe to say that in SDR content, after a few adjustments in the settings, ChooseTV 3 performs really well. It fares much worse, although still definitely better than before calibration, when it comes to HDR content. The white balance has been brought in line, but the limitations of the IPS panel are insurmountable. The lack of local dimming means that even the smallest elements can be overexposed, which is immediately noticeable. Colour-wise, the effect has also improved, although it is far from perfect – many errors still exceed the threshold of four, and even five delta E units, remaining visible to the human eye. It was already clear earlier that ChooseTV 3 is not a television designed to impress with HDR quality. Nevertheless, it is pleasing that in SDR content, after calibration, the picture can look really great and in this category, the television pleasantly surprised us.

Calibration primarily corrected the white balance and removed the previously noticeable warm cast. After the correction, whites no longer had a yellow tint and colours became more neutral and natural. The biggest improvement was seen in SDR material, where the picture looked even and much closer to the reference. A similar effect was achieved in HDR. After calibration the image became more controlled, although not all of the TV’s limitations could be eliminated. The main issue remained intense reds, which were not always reproduced with sufficient precision. In practice the MRGB85 handles everyday SDR content very well, but in more demanding HDR material its limitations are still clearly visible.

Bravia 3 brings something more to the Sony television family than just a shared name. It stands out primarily for its ability to enhance the quality of weaker materials thanks to the processor used. Of course, we won’t find the advanced XR chip known from more expensive models here, but nonetheless, it must be said that the image in lower resolution looked surprisingly good. The scaling worked effectively, and most areas of the screen were free from the typical excessive edge roughness found in budget constructions.

Also worthy of attention is the function that improves the smoothness of tonal transitions. In high setting, it works really well, effectively masking gradation imperfections without significant loss of detail. It does happen that the algorithm overzealously smooths elements that should remain sharp – for example, faces – however, in the overall assessment, the effect is beneficial. The best results were achieved precisely at the highest setting, and this is the option we could recommend to those watching lower-quality content.

Upscaling and digital image processing perform quite well in the LG MRGB85. The Alpha 8 AI 4K Gen7 processor efficiently upscales lower-resolution material, and you can easily turn off overscan regardless of the source. The TV also handles compression artefacts well. The "Smooth Gradation" function can effectively reduce visible banding and tonal unevenness, but it isn't always precise. At higher settings it can also smooth out fine details, such as the texture of materials. A plus is that it doesn't remove film grain. The safest option is the "Low" or "Medium" setting, which offers the best compromise between artefact reduction and preserving detail.

Motion smoothness has never been a strong point of televisions equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has included something that may appeal to those more sensitive to the way images are displayed. I'm talking about the proprietary motion smoother, Motion Flow, which gives the user plenty of adjustment options. With it, one can make the image smoother, almost theatrical, or stick to a more cinematic style with characteristic judder that many people simply associate with a filmic atmosphere. These functions work with content at lower frame rates, such as films and series recorded at 24 or 30 frames per second, which is the material we deal with on a daily basis. This is precisely where the motion smoother proves to be one of the most important features in everyday TV usage, and here, the Bravia 3 performs really decently.

The LG MRGB85 is fitted with a VA panel with a native 144 Hz refresh rate, so its motion handling is very good. The TV easily handles 120 Hz content from consoles and higher refresh rates when connected to a PC. That matters not only for gaming but also when watching sport, where camera motion is noticeably smoother than on basic 60 Hz panels. There’s also the TruMotion system, which lets you set the level of motion smoothing yourself. You can keep a more cinematic motion or increase smoothness, which works well for live sports and TV programmes. The adjustment range is wide, so you can easily tailor the motion smoothing to your own preferences.

Bravia 3 is not gear for e-sports enthusiasts or fans of late-night marathons with a controller in hand. The lack of 120 Hz refresh rate and HDMI 2.1 ports shuts down the conversation before it even gets started. This is a TV for casual gamers who, after work, will fire up FIFA or racing games, not for someone who measures every frame in a spreadsheet. Nonetheless, Sony has thrown in a few nice additions so it’s not completely sparse. ALLM works as it should, automatically switching the TV to game mode (low latency). We even find a simple Game Bar here, which is clear and intuitive. However, the biggest curiosity here is the PlayStation Portal app. Thanks to this, you can launch PS5 games wirelessly and see them right on the TV screen. It sounds great, but it only takes a few minutes to feel significant lag. In our opinion, it's more of a showcase of capabilities than something that can be used day-to-day. If someone really wants to game, it's better to plug the console in with an HDMI cable and forget about wireless issues.

When it comes to gaming, the LG MRGB85 performs by far the best. The manufacturer hasn’t skimped on the kit and has essentially carried over the full suite of features from pricier TVs into this model. You get three HDMI 2.1 ports with full 48 Gb/s bandwidth. Each supports 4K 120 Hz from a console, and when connected to a PC also 4K 144 Hz. So you don’t need to worry which port to plug your console or PC into, as they all offer the same set of capabilities.

On board you’ll also find VRR, AMD FreeSync Premium, NVIDIA G-Sync Compatible, ALLM and HGiG. Dolby Vision Gaming is included too, allowing supported games to use high refresh rates and dynamic HDR simultaneously on Xbox. Rounding it off is Game Optimizer, a handy in-game menu. Without leaving the game you can change the picture profile, brighten shadow detail or check the current frame rate. In terms of gaming features, the MRGB85 therefore offers almost the same as significantly more expensive LG models.
