Samsung QLED Q80D vs Samsung U8000F (IPS)

In the context of HDR, the Samsung Q80D television delivers impressive brightness performance in tested movie scenes, achieving levels between 600 to 900 nits when the frame is filled with light. This brightness enhances the vibrancy of the image and allows users to perceive the differences between HDR and SDR quality. However, challenges arise when small light effects appear against a dark background. For instance, in specific scenes, such as test slide 4 from Sicario 2, there is a noticeable drop in brightness due to the larger size of the dimming zones employed by the television. This limitation, coupled with the local dimming algorithm, affects the TV's ability to accurately display small bright elements on dark backgrounds, leading to a lack of brightness that can diminish the HDR effect, making it appear similar to SDR quality.

Better does not mean good – and that perfectly summarizes the capabilities of the U8092F when it comes to displaying bright movie scenes in HDR mode. The brightness of the panel is just under 250 nits, which is definitely too little to enjoy any lighting effects. An interesting situation was noted during the measurement of the fourth scene from the movie Sicario 2 – the television clearly dimmed the entire screen in an attempt to achieve better black levels (which are still weak). One could even suggest that the device uses some form of "global dimming," but unfortunately, the results are still very poor. To make matters worse, the television does not support a wide color gamut – the coverage of the DCI-P3 space is about 80%, so there’s no hope for truly vibrant colors. HDR images here look rather like lightly brightened SDR, and that's the form we would suggest sticking to when it comes to this television.

In "Filmmaker" mode, which is considered the best out-of-the-box choice, the Samsung Q80D demonstrates solid colour reproduction. However, when viewing SDR content, there is a visible drop at the beginning of the gamma curve, suggesting that details in dark scenes may be less clear, which could detract from the overall viewing experience. While the white balance in SDR content is generally accurate, significant drops in blue at screen coverage above 70% can lead to less natural hues in both bright and dark scenes. Users might notice that some blue elements appear less intense, resulting in a warmer tint to the colour presentation.

For HDR content, the EOTF (Electro-Optical Transfer Function) curve being above the reference line most of the time indicates that the TV may struggle to accurately reproduce brightness and detail in the brighter areas of the image, which can be less than ideal for viewers. Additionally, there is a notable drop at the beginning of this graph, signifying the TV's difficulty in reproducing brightness in dark areas; this limitation is apparent in contrast and black tests, where several scenes fail to showcase the TV's full brightness potential.

Regarding white balance, the initial performance on the chart is promising, however, a sharp drop in red, coupled with a significant rise in blue, may lead to inaccuracies in reproducing certain skin tones and other key colours. This issue can be particularly noticeable in scenes where colour details are essential, potentially affecting the viewer's overall experience.

The Samsung U8000F was tested in the best possible picture mode built into the TV, which is Filmmaker Mode. This mode should – at least in theory – offer a cinematic, reference-quality image without unnecessary enhancements. For SDR content (mainly HD/SD), the TV performed surprisingly well straight out of the box. White balance errors hovered around a value of 3, which is roughly at the threshold of perception. The only complaint could be about brightness management – the gamma chart showed a slight tendency to brighten or darken certain areas, but overall it performed quite well for this price segment.

Unfortunately, it looks much worse in HDR mode. Although the white balance wasn't terrible, the TV had significant color errors – particularly noticeable on the Color Checker chart, where almost every sample landed outside the target point. The HDR image simply looks unnatural, and colors can be shifted, dull, or too cool. This largely stems from the fact that the U8000F does not support a wide color gamut (DCI-P3). The TV is physically incapable of displaying accurate colors in HDR standard – and this unfortunately shows in every more demanding material.

After calibration, the Samsung Q80D’s Movie mode offers a noticeable improvement over the out-of-the-box settings. Samsung provides an advanced suite of calibration tools, including 2- and 20-point grayscale adjustments as well as a CMS (Colour Management System), allowing for precise control over both SDR and HDR content. The calibration greatly enhances white balance, although minor errors remain in HDR content toward the end of the graph. Contrast has also improved, and the gamma curve for SDR content now aligns well with expected levels.

In HDR, the EOTF curve initially appears to sit ideally, however, closer examination reveals all lines are slightly above the reference line, a phenomenon that may be seen as the TV "enhancing" brightness for added appeal. This effect, however, comes at a cost: while the screen may appear brighter overall, it sacrifices detail in darker areas, leading to a loss of subtle textures in shadowed scenes. As a result, scenes with deep shadows or dark elements may lose some finer visual details that would enhance the viewing experience.

Although the U8000F offered quite a decent picture in SDR right out of the box, we were able to adjust it a little more. We managed to eliminate a slightly purplish tint and calibrate the gamma to a more reasonable level. However, the television still tends to overemphasize the smallest and brightest parts of the image – the gamma chart shows a characteristic "dip" that is difficult to completely correct.

Unfortunately, the situation looks worse in HDR. It's hard to talk about any significant improvement here – the television is simply not designed for HDR content. We tried to adjust the picture in the advanced settings, but despite everything, the color errors remained quite large – a delta E above 7 indicates noticeable deviations. It's a bit of a shame, but that's the charm of a budget design. In SDR, the U8000F performs just fine, while HDR is simply not its league.

Performing admirably with low-quality content, the Q80D’s noise reduction feature uses gentle gradation to smooth out unwanted image disturbances. However, this technique can also soften certain details, like film grain, that some viewers might prefer to retain. For those who appreciate a more polished and smoother image, particularly with lower-resolution material, this becomes a significant advantage.

In terms of image scaling, the Q80D stands out, enhancing both quality and detail for lower-resolution media. Advanced processing technology reduces artefacts and maintains clarity, as seen in the clean edges and absence of fraying in elements like branches during test scenes. This capability makes it an excellent option for viewers seeking an enhanced and comfortable viewing experience, even with less-than-ideal content quality.

When it comes to how the Samsung U8000F handles lower-quality materials, we have to admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same place in the lineup.

This year's model is equipped with a function to improve the fluidity of tonal transitions, which has been implemented much better than last year. Yes, the television still uses quite strong algorithms that can distort details or remove film grain, but even so – it can be confidently said that it works effectively.

However, not everything went perfectly. The U8000F has noticeable issues with slight frame cutting when watching very old content in very low resolution. If someone plans to play their old VHS tape, they should be prepared for the image to appear slightly “cut off.”

Motion smoothness and blur reduction are standout features on the Samsung Q80D TV, thanks to its 120Hz panel and impressive response time. Users have two customisation options to enhance smoothness: "Motion Blur Reduction," adjustable on a 10-step scale for refined control, and "Blur Reduction," which works particularly well at higher refresh rates, enhancing clarity in fast-moving scenes. In the UFO test, the panel performs without trailing or forward-cloning effects, indicating a lack of overshoot and delivering clear, sharp visuals during rapid motion.

The Samsung U8000F is equipped with a 60 Hz panel, so right from the start, it’s clear that we shouldn’t expect any miracles. This is simply the standard in this class – sufficient for everyday viewing, but without any fireworks.

The TV offers one motion smoothing slider – a feature called "Motion Blur Reduction", which allows us to adjust the smoothness of the image in movies. Higher settings provide a more "theatrical" and smoothed effect, while lower settings help retain the original character of the film with a slight 24p effect. Interestingly, there is a feature called "Clear Motion LED", which is a BFI mode – that inserts black frames between the frames of the picture to improve motion clarity. However, in practice, the screen flickers significantly when activated, and it should be regarded more as an experiment than something that realistically enhances gaming comfort.

The Samsung Q80D is a fantastic choice for gamers, offering a range of advanced gaming features that are rare in this price category. Equipped with four HDMI 2.1 ports, it enables key functionalities like ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz support at 4K resolution, ensuring smooth and responsive visuals, essential for fast-paced gaming. The TV also supports HGIG (HDR Gaming Interest Group) for optimal HDR display in games and includes a Game Bar for quick access to gaming settings. Gamers with Nvidia graphics cards will appreciate the G-Sync support that eliminates screen stuttering and tearing.

Although it lacks Dolby Vision support, which may disappoint those seeking that HDR format, Samsung has partnered with Microsoft since 2022 to provide the Xbox Game Pass app, enabling cloud gaming access to a wide library of games without a console.

Samsung U8000F offers a basic set of features for gamers, which nonetheless may be sufficient for less demanding users. We have an automatic game mode here – when a game is launched on the console, the TV automatically switches to low latency mode, which significantly improves response time. We also find the VRR feature, or variable refresh rate, which operates within a range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the "tearing" effect, as long as we stay within this range.

And unfortunately, that's about it for the advantages. Add-ons like Game Bar or higher refresh rates are reserved for the higher models of Samsung from the 2025 line. In theory, the TV also supports the HGiG feature, which should adjust HDR images to the intentions of game developers. Unfortunately – even though this feature appears in promotional brochures and store materials – its configuration on the Xbox console turned out to be... impossible in practice.
