> 8K TVs may be driven at 8K 60 Hz with no chroma subsampling by using HDMI 2.1, which is available on all current (Nvidia RTX 4000 series and AMD 7000 series) and previous gen (Nvidia RTX 3000 series, AMD 6000 series) graphics cards. Older computers with GPUs outputting DisplayPort 1.4 may use adapters such as the Club3D one to achieve 8K 60 Hz.
Isn't "plain" DP 1.4 confined to HBR3 - thus its maximum refresh rate is 8K-30Hz?
