differences of resolutions

HDMI 2.1 unveils itself and lets us see a significant increase in its capabilities. The HDMI Forum explained that it can support resolutions up to 10K (10 240 x 4320p)! It can also display 8K at 60 Hz or 4K at 120 Hz. The standard is of course compatible with the Dynamic HDR, which adapts the various parameters (such as contrast, brightness or colorimetry) of the watched videos live.

The sound aspect is not to be outdone with the support of eARC, which makes it possible to take advantage of 3D Atmos/DTS: X audio formats. Finally, the VRR mode is aimed directly at gamers because it offers a variable refresh rate, which allows you to enjoy a better fluidity in game and reduce the lagoon. No wonder for people who already know Nvidia’s G-Sync technology.

Given the weak content of the resolutions mentioned above, you will have understood that it is a question of taking the lead here. But the democratization of the 4K is progressing. It is therefore understandable that the flagship standard for home audio-visuals must keep one (sacred) one step ahead.
