Hi.

There seems to be an issue with my Blade 17 2022. I have the RTX 3080Ti, 12900H, 32GB RAM, 4K/144Hz variant. I'm connecting the Blade to my LG C5 which has full 48Gbps HDMI 2.1 ports (all 4 of them), and I'm using a HDMI 2.1 48Gbps certified cable. So the TV and cable are not the issue. Basically, I'm unable to use full 4K, 120HZ, 10bit HDR with the Blade 17, even though the 3080Ti is supposed to have a HDMI 48Gbps port. I am using dedicated GPU only, no Nvidia Optimus. I've seen a few other people with this issue online and Razer seem to be quiet on the matter. Is there a possibility the HDMI port on the Blade 17 2022 doesn't support full HDMI 48Gbps spec? 

 

Would very much appreciate a reply from Razer/anyone else who can help. Advertising the HDMI port on the Blade 17 2022 is misleading as it clearly does not work at 4K/120HZ/HDR/Full RGB. 

 

Please help if you can. Cheers!
