Does the length of HDMI 2.1 cable matter?
Kjelt:
If you need an HDMI cable for 48Gbps longer than two metres then you should buy an active optical cable with transceivers on both ends. Then the length does not matter much anymore.
I use 15m of these cables for 4K/10bit 60Hz video, never a glitch.

I only need 3m maximum. Any recommended active optical cable with transceivers on both ends?

You don’t need an optical cable for just 3m. Just get a good quality cable and it’ll be fine. Good quality doesn’t have to be expensive: Blue Jeans Cable sells a 3m cable specifically for UHD for $22.

The common estimation for the maximal length of a passive HDMI 2.1 cable is 5m.
