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.
