The QLED Q80T from the Korean manufacturer Samsung clearly performs better in a direct comparison. Thanks to the VA panel, it has a much better contrast ratio of 4300:1 with a deeper, more even black and therefore has clearly superior picture quality in dark rooms – although both have full array local dimming. The NANO90 can certainly keep up in bright rooms, but doesn’t quite reach the Q80T’s results due to the lower peak brightness. The higher peak brightness of ~820 Nits makes HDR highlights stand out better and the wider color gamut produces a more impressive display of HDR content. Although the viewing angle of the NANO90 is quite impressive, the one of the Q80T is even better. It uses Samsung’s ultra viewing angle layer to overcome the disadvantage of the VA panel.
If you want to buy a TV for sports you should consider the Q80T because of the NANO’s dirty screen effect. The picture simply looks cleaner and it is more fun to watch the teams rushing over the grass or ice. In gaming, both devices perform equally well, but the HDR performance of the Q80T is way better. As a consequence HDR games are way better displayed.
At first glance, LG’s NANO90 can easily keep up with the XH90. But there are some factors that are not quite taken into account by our comparison chart. The NANO90’s blacks are not really uniform. Its corners are darker and the dirty screen effect is clearly visible in the centre of the screen. This is particularly annoying when watching sports, as large areas that should actually have the same colour can look non-uniform and dirty.
Because the NANO90 uses an IPS panel, its viewing angle is considerably larger than that of its Japanese competitor. This makes it much more flexible to use – even if several people want to look at the TV, or if the couch is at an angle to the TV. Although the viewing angle is smaller than other TVs with IPS panel, it is far superior to the XH90. However, this panel has the disadvantage of having a much lower contrast ratio and a lower peak brightness. As a result, the XH90’s picture quality is better in dark rooms and HDR content is definitely displayed more beautifully.
In the gaming category, both TVs show a similarly good performance – due to an equal input lag, HDMI 2.1 and a similar response time. However, the NANO90’s IPS panel allows several people to play together at the same time. A Fifa tournament is therefore more likely to take place on the NANO90. However, the XH90 has the better overall performance, especially in terms of HDR performance and picture quality.
Compared to its little brother, the NANO90 is clearly the better TV. Instead of the Edge-Lit LED backlight of the NANO85, it has Full Array Local Dimming, which improves its picture quality considerably. The little brother’s peak brightness is very low with ~350 Nits. This means that the display of HDR content is not as good as with the NANO90 – even if it does not perform as well in this respect. But not in every case the NANO90 is superior. When it comes to gaming, the NANO85 is just as good, although the input lag of the NANO90 is slightly better. The Dirty Screen effect, which is present on both devices, is not as noticeable on the NANO85. This way sports is displayed better and it is therefore more fun to watch on the NANO85.
