Samsung Q90T vs Q80T TV comparison 2021/04

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 nitsSI unit of luminance: 1 nit = 1 cd/m² – The best way of measuring and comparing a TVs brightness  , which makes the QLED produce an outstandingly good picture in bright rooms. HDRHigh Dynamic Range – image/video with more dynamic range (contrast range) 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 SDRStandard Dynamic Range – image/video with a conventional gamma curve (opposite: HDR) – “normal” videos 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 VAVertical Alignment, type of LCD Panel 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 nitsSI unit of luminance: 1 nit = 1 cd/m² – The best way of measuring and comparing a TVs brightness   – 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 HDRHigh Dynamic Range – image/video with more dynamic range (contrast range) 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, ALLMAuto Low Latency Mode – Automatically detects connected consoles and keeps input lag as low as possible. and VRRVariable Refresh Rate – synchronizes the display’s refresh rate with the output refresh rate of the graphics card are available on both devices, so the performance is quite similar in this category.
