Samsung Q90T vs Q80T TV Comparison 2020/08


When buying a high-end 4K QLED, the question arises, if it has to be the flagship of the 4K QLED series or if the next cheaper representative of the series will be equally convincing. The datasheet shows that the Q90T has some additional features that Samsung saved with the Q80T. But is this really reflected in the overall performance, or can one also confidently choose the cheaper Q80T? We’ll take a closer look at the two and show you what the difference is.

Detailed comparison: Samsung Q90T or Q80T

With the Q90T you get a true all-round television that produces a very respectable picture under almost all conditions. Despite the extended viewing angle, it has an incredibly high contrast ratio of 10500:1 and can also become very bright. The peak brightness is about 1400 nits, which makes the QLED produce an outstandingly good picture in bright rooms. HDR content is also displayed brilliantly and bright highlights can be brought into focus very well. In dark rooms the picture quality is also excellent, even if there are other TVs like OLEDs that put the Q90T in its place. Compared to the Q80T, the picture quality of SDR and HDR content is much better, so the flagship is clearly ahead. However, the Q90T is affected by the dirty screen effect, so that in large scenes with the same color, such as a soccer field, the image looks slightly dirty - here the Q80T can do much better!
The Samsung Q80T QLED is a good TV for most content. It uses Samsung's Ultra Viewing Angle layer to extend the viewing angle - which is probably the biggest drawback of the cheaper models with VA panels. However, this layer also improves the TV's reflective properties, making it more suitable for the use in brighter surroundings. But the additional layer reduces the brightness of the TV, which is not too low at around 700 nits - but does not get nearly as bright as the Q90T. In dark surroundings, the VA panel produces a good picture quality due to its high contrast ratio and deep blacks, which are further optimized by the Full Array Local Dimming feature. The Q80T can display HDR content quite nicely, but the peak brightness is not high enough to make the bright highlights really stand out. Gaming is incredibly fun on the Q80T. Besides a low input lag and a very good motion handling it has all the features you could need for gaming. HDMI 2.1, ALLM and VRR are available on both devices, so the performance is quite similar in this category.

Our conclusion: Very convincing performance, but still inferior in many areas

There’s no question, the Q80T is a great TV that can be used very flexibly and delivers a good performance. However, with the leading QLED model Q90T it can not quite hold its own in many categories. Its picture quality is clearly superior in both bright and dark environments, so all content can be displayed better on the Q90T. So if you want the best possible HDR performance the Q90T is the better choice. For those who are more into next gen gaming, the Q80T will also be a great choice. Both devices have everything you need – including the HDMI 2.1 interface for [email protected]. Surprisingly, the motion handling of the Q80T is slightly better with a response time below 3ms. But the Q90T makes up for this with a lower input lag, making both TVs feel very responsive. So it is really grumbling on a high level, as both TVs are very good – although the Q90T can be considered the winner due to the better picture quality.
