IFFALCON U85X vs Dreame Q100

iFFALCON U85 handles HDR in a rather twofold manner – on one hand, it can surprise with solid peak brightness of around 650 nits, which places it well above average in this price segment. This is especially evident in bright, full-screen scenes. Examples from films such as Life of Pi or the final test sequences from The Meg prove that the television can maintain the power and essence of HDR effect when the entire panel needs to "ignite," delivering truly satisfying experiences. However, problems arise in high-contrast scenes, where smaller, bright details appear on the screen; the dimming algorithms prioritize black depth to such an extent that they can stifle the brightness of small light points to just 100 nits, which drastically reduces image dynamics and deprives us of the true "bite" we expect from HDR standards. On a brighter note, however, the colours remain impressive, as the use of the PFS phosphor filter (marketed as QLED by the manufacturer) showcases them very well, achieving nearly 94% coverage of the DCI-P3 colour palette, allowing for a vibrant and rich image in most content.

Unfortunately the Dreame Q100 is too simple, and above all too dim, a television to talk about a true HDR effect. The peak brightness we measured reaches at most about 300 nits, which is clearly too little for bright elements of the image to actually 'pop' with light. In fact, this is a level we more often associate with SDR material than with HDR. It therefore lacks the brightness headroom offered by more expensive televisions that makes highlights, reflections and the sun look noticeably more striking.

HDR colours

Fortunately the Q100 makes up for this a little elsewhere. The manufacturer markets it as a QLED television, although in practice a PFS filter is responsible for widening the colour palette. The DCI-P3 colour space we measured is covered at roughly 92%, and BT.2020 at about 67%. These are not top-tier figures, but still clearly better than simple LCD televisions without an additional gamut-expanding layer. As a result, HDR material can at least offer more saturated and varied colours, even if the brightness itself does not yet allow us to speak of a fully fledged HDR effect.

We tested the factory colours on the iFFALCON U85X model in 'Film' mode, which is definitely the most reliable among all available settings, although it is still far from perfect. The main issue that stands out in both SDR and HDR content is the incorrect white balance – an excess of blue and red components gives the image a slight purple tint, which disrupts the naturalness of the film scenes. An even greater challenge is the way the television manages its brightness. Analyzing the gamma chart for the SDR signal, we noticed significant instability: instead of adhering to the standard value of 2.4, the device oscillates around 2.2, only to suddenly make an unnatural jump towards 3.0. In practice, this leads to confusing effects – large, bright areas on the screen appear too dark, while smaller elements are unnecessarily brightened. A similar characteristic can be found in the EOTF curve, which makes the image unpredictable and loses its cinematic authenticity.

We chose the "Film" mode for testing and, in our opinion, it is by far the best of the available presets. There are none of the heavily boosted, unnatural colours you can see, for example, in the Vivid/Dynamic mode. The picture looks quite reasonable straight away, although it falls a little short of perfect. In SDR material the most noticeable issue was a slight warming of the image. The white balance had too much red, which made whites lean towards a warmer hue, and a similar tint was visible in shades of grey. In HDR the situation was a little different. Here blue had a slight advantage, making the picture a touch cooler. These are not major faults, though. For such an inexpensive TV, the factory settings on our unit were fairly decent, and the "Film" mode already delivers a relatively natural image without much fiddling with the settings.

After professional calibration of the movie mode, we must admit that the result is more than satisfactory – the iFFALCON U85X undergoes a true transformation. Colour errors in SDR content have dropped to a level below 2, which makes them virtually imperceptible to the human eye. We have managed to set the white balance almost perfectly, and brightness management (gamma) has become nearly exemplary. As a result, with standard quality materials, the television simply looks perfect and it is difficult to fault it.

In the case of HDR signal, the situation has also significantly improved, although here the nature of the device becomes a bit more evident. Colour errors have been reduced to around 3, which is an outstanding result in this price range. However, it is worth taking a look at the EOTF graph (available on the right side of the screen in the filters: 4K HDR, gamma / EOTF) to notice what is not immediately visible regarding the brightness management by the U85. Although the reference line looks decent, in real film scenes, the television still interprets the signal “in its own way” due to very aggressive local dimming algorithms. Does this disqualify this model for watching HDR content? Absolutely not. It's simply a typical affliction of almost every Mini-LED, which must reconcile high brightness with the attempt to maintain deep blacks. One simply needs to be aware of these technical limitations, which are unavoidable in this segment.

Contrary to appearances, the Dreame Q100 is quite well prepared for image calibration. The menu contains quite a few advanced picture settings that allow its characteristics to be adjusted fairly precisely. In our case the most work was required on the white balance, both in SDR and HDR. After correction SDR content looked very good. We managed to achieve a practically neutral white balance and natural colours, with the main remaining limitation being the black level itself, stemming from the panel construction and the lack of local dimming.

In HDR we also managed to improve white balance and colour reproduction, but here the limitations of the TV's electronics become apparent more quickly. Even after very precise adjustment of the EOTF curve, the Q100 does not always follow it correctly during actual scenes. In some content it can also brighten the image further, causing some parts to look brighter than they should, and in bright areas some details can be lost as a result.

When it comes to upscaling the image to 4K resolution, the iFFALCON U85X performs well. The device efficiently enhances low-quality signals, making even older materials look clean and clear on the 4K panel. At extremely low resolutions, such as 480p, one can notice slightly jagged edges (especially on fine lines), but let's be honest – this is a scenario that you will encounter only when watching very old recordings, so in everyday use, it is not a real problem.

Much worse is the digital processing aimed at smoothing tonal transitions. Although in the menu we find the “Gradual Smoothing” function, its effectiveness is at least questionable. In practice, it does not effectively eliminate banding (colour banding), and worse, it can cause more harm than good. This filter can be too aggressive in areas where it shouldn’t, artificially smoothing details that should not be altered, such as the natural texture of the face or fine details of skin texture. Instead of improving quality, this function can give the image an unnatural, “plastic” appearance, so it is best to use it with great caution or, preferably, leave it switched off.

The weakest point of the Dreame Q100 is its digital image processing capabilities. The processor used copes only moderately well with enhancing weaker sources, and the menu lacks any function that effectively smooths unsightly tonal transitions or reduces visible posterisation. Upscaling itself is also unimpressive. With low-resolution material the image is fairly soft and lacks faithful detail reproduction. Additionally, the Q100 tends to overscan, slightly cropping the edges of the image with very poor sources, such as 480p material. In everyday viewing of HD or 4K content this won't be a major problem, but with older recordings the processor's limitations become clearly visible.

In contrast to budget constructions, which in dynamic sports scenes can resemble a slideshow, the iFFALCON U85X is a heavyweight contender equipped with a panel that has a native refresh rate of 144Hz. However, it is worth noting that in the world of films, series, or sports, we will primarily operate at 120Hz due to the specifics of how image enhancement systems function. Such a fast panel is excellent news for gamers and sports fans as it opens the door to advanced motion settings that simply do not exist in cheaper 60Hz models.

We manage everything from the menu “Motion Clarity”, where instead of using pre-set, often overly aggressive modes, we definitely recommend our own configuration based on two sliders. The most important of these, motion blur reduction, is responsible for fluidity in films – here, it’s best to aim for a value of around 4, which will maintain a natural, cinematic character of motion without falling into the artificial “soap opera effect.” Meanwhile, the first slider, motion blur reduction, is the key to success in sports broadcasts. In this case, it’s worth going all out and setting it to maximum, ensuring that the image during fast actions on the field remains sharp, while troublesome trailing is eliminated.

The VA panel used in the Dreame Q100 has a native 60 Hz refresh rate, so from the outset this is not a TV designed for the most demanding sports fans or gamers. The manufacturer does mention the ability to run at 120 Hz, and that option is indeed available, but it mainly applies to a mode intended for gamers. In everyday use the Q100 should therefore be treated as a conventional 60 Hz TV. For fast-paced sports broadcasts or rapid gameplay this means less smooth motion than in models with 120 Hz panels or higher. On the plus side, the panel’s response time is worth noting. The VA panel does not exhibit excessive smearing, so motion remains quite clear and does not leave strong, blurred trails behind moving objects. For films you can also use a simple motion-smoothing system. The manufacturer has prepared several ready-made presets that help reduce the characteristic judder in material shot at 24 frames per second.

iFFALCON U85X is an outstanding piece of equipment for gamers that has just about everything one can expect from a modern screen for consoles or PCs. We find here two full-fledged HDMI 2.1 ports with full bandwidth of 48 Gbps, which opens the door to key technologies such as VRR and ALLM, ensuring smooth gameplay without tearing the image and with minimal latency. The television handles high refresh rates in various resolutions without any problems, and a real curiosity is the mode that allows for achieving up to 240Hz when dropping down to Full HD quality. The whole thing is managed by the Game Bar (which is a faithful copy from TCL), allowing for instant switching of picture modes, customising the interface appearance, or even adding a virtual crosshair in the middle of the screen.

The Dreame Q100 is not a strictly gaming device, but for console use it offers a reasonable package. It provides VRR to eliminate screen tearing and ALLM, which automatically switches the TV to a low-latency mode when it detects a console signal. An interesting compromise is support for a 120 Hz mode. The panel won’t achieve that refresh rate in 4K, but dropping to 1080p lets you play at 120 frames per second. If a given title prioritises smoothness over high resolution (and the game offers such a mode), it’s worth using this option. There’s also a handy Game Bar on board, allowing you to quickly change display settings, switch the refresh mode or add a virtual crosshair. Admittedly the HGiG implementation is weak here, but it earns points for supporting Dolby Vision Gaming on Xbox Series X and S. This is not a panel for technological purists, but for casual console gaming it performs flawlessly, especially when you opt to trade 4K for a smoother Full HD.
