Sharp GP7 vs Samsung Q6F (IPS)

In terms of HDR, Sharp GP7 can pleasantly surprise us. A maximum brightness of around 500 nits is the threshold at which the real benefits of high dynamic range become visible. During our tests, we achieved stable values between 430 and 500 nits, which translated to clearer differentiation of elements in both bright and slightly darker scenes. Additionally, the DCI-P3 colour space coverage was around 95%, allowing for vibrant, visually pleasing colours. Of course, this is not the highest league, but considering this price range – it’s a big plus.

The Samsung Q6F is, unfortunately, a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is a value that is decidedly too low to even talk about any effect of “high dynamic range,” or HDR. In practice, it’s better to stick to content in SDR format, which simply looks more predictable on this television. Another problem is the global dimming technique – in scenes with a lot of black, the television drastically dims the entire panel to artificially improve the black levels. This causes the image to become even darker, and the brightness can drop below 100 nits. The only consolation is supposed to be the QLED technology, but even here it is average. The layer of quantum dots used is not of the highest quality, as the coverage of the DCI-P3 colour palette does not exceed 90%. As a result, the colours in HDR content may simply appear under-saturated.

Upon removing it from the box, in movie mode, GP7 does not perform poorly at all. In HD materials, we noticed slight disturbances in white balance – drops in red and blue, which made the image have a somewhat greenish hue. This is evident, for example, on the faces of characters, which become less three-dimensional. The gamma is somewhat brightened in places, resulting in less deep blacks. In 4K HDR content, a cooler, bluish tone additionally comes to the fore, making the colours appear less natural. On the other hand, looking from the perspective of "straight out of the box," these settings are not bad – only minor adjustments are needed, and with the help of specific tools, we will try to improve them.

We tested the television in Filmmaker mode, which showed us two completely different facets of this model. Looking at SDR content, we were genuinely shocked at how good this television looks straight out of the box. It was really difficult to find fault with anything here. Despite a slight 'muddiness' in the white balance or somewhat brightened details in the blacks (which directly stem from the design of the IPS panel), the colour errors hovered around a level of '2'. This result is not only surprisingly good but downright amazing, considering the price of this device.

On the other hand, what the Q6F displayed in terms of colours after switching to HDR mode was a very unpleasant surprise. The errors in colour reproduction and palette were so enormous that our charts literally ran out of scale. Of course, since Samsung even in such an affordable model offers very extensive calibration options, we decided to approach the issue professionally and see what could be done during calibration.

Calibration really makes a difference in Sharp GP7. After making adjustments, we achieved a better white balance in HD content, and the colours began to appear much more natural, with minimal deviations and without a noticeable dominance of individual hues. In 4K HDR, the change is not as spectacular, but still noticeable. The gamma has been brought to a more neutral level, although there remains an issue with a slight boost in the brightest details on the screen. The lack of control over dynamic tone mapping limits our manoeuvrability, but nonetheless, it is a significant step forward compared to the factory settings.

After our calibration, the colours in SDR mode looked even better – the result is truly surprising, as colour errors at the '1' level are something generally seen in devices costing several thousand pounds. In this regard, the Q6F is really an excellent screen for everyday television, less demanding series or films. Unfortunately, our intervention in the HDR mode did not bring a noticeable improvement. The television, due to its poor blacks and low coverage of a wide colour gamut, still has significant issues with proper colour saturation, especially reds. This is an example of a device where HDR exists mainly as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

The television is quite capable of scaling lower quality content. Our test patterns were well reproduced, and although there was minimal banding on fine, delicate shapes (for example, thin branches), it still looked satisfactory. Additionally, Sharp GP7 offers a "10-bit colour reproduction" feature to smooth tonal transitions in poor quality materials. It is useful, but at the cost of some details, so we recommend turning it on only when we are truly watching something subpar.

Q6F performs very well in upscaling lower-resolution content to native 4K. The scaling here is surprisingly good, even for such an inexpensive television from the QLED series. The only downside is the situation where we are watching very low-resolution materials, such as 576p (typical for old DVD players) – in which case the image may be slightly cropped. This is due to the fact that the television does not allow the Overscan function to be turned off, which is a typical issue with Samsung devices.

The situation is completely different when it comes to digital processing, specifically the attempt to smooth the image of unwanted artifacts. Here the television completely fails. Although there is a function in the menu called "Noise Reduction," it yields no visible results regardless of the slider setting. The only thing it manages to do is introduce undesired errors in the image. Despite its presence in the system, we definitely do not recommend using it.

With a 60 Hz panel and an average response time, it’s hard to expect miraculous smoothness. In dynamic tests, such as the one with the “little green man”, it’s evident that the picture can stutter and occasionally lose sharpness. For watching films and series, this is acceptable, especially as you can make use of a motion smoother with three levels of adjustment. However, if we are keen on ultra-smooth sports broadcasts or super-responsive gaming, we may feel unsatisfied.

The 60 Hz panel in the Samsung Q6F is standard for this price range, making it rather average for dynamic sports or gaming. However, when it comes to films, the television performs quite well thanks to the motion smoothing feature. The "Motion Reduction" option allows you to adjust the smoothness of movement to your own preferences – from maintaining a cinematic character to complete fluidity.

Let's not kid ourselves – GP7 Sharp is not a television for the most demanding console gamers. Yes, it has ALLM which automatically switches the TV to low latency mode, but it lacks VRR or G-Sync. We also won't find any advanced menu to assist in selecting settings during gameplay. Dolby Vision in games? It's there, but with such a high input lag that it's hard to speak of comfort. If we play occasionally and are not aiming for the highest standards, it can be managed, but fans of technological innovations will be disappointed.

We're not going to beat around the bush – the Q6F is not a television designed for gamers. Although it features additions like ALLM (automatic low latency mode) and VRR frame synchronisation for consoles, the list of advantages basically ends there. Aside from these basics, the television offers nothing more that would satisfy those who spend a lot of time in front of a console. It’s a great shame that such a useful tool as Game Bar, which allows for quick control of game parameters in Samsung's higher models, is missing here. In terms of gaming, this model is absolutely basic and is only suitable for "casual" gamers.
