Is HDMI really a roadblock to gaming when DisplayPort exists?

It's a blocker if you want to use a TV, there are almost 0 TVs with DP. This HDMI licensing crap is also the reason a Steam Deck can't output HDMI > 4K@60 unless you install Windows on it.

  • Aren't there some hardware dongles to translate from DP to HDMI?

    • DP is something like a free superset of HDMI, so you can use a fully passive DP-HDMI cable. Obviously the feature set will be limited, but it will work.

      DP however can't transfer audio, which doesn't matter for a desktop but matters a lot for a TV.

Up until a year or two ago, the majority of monitors (and graphic cards) used DisplayPort 1.4 and HDMI 2.1. With HDMI 2.1 (42 Gbps) having more bandwidth than the DisplayPort (26 Gbps).

This is my case with my relatively new/high-end RTX 4080 and OLED monitor. So until I upgrade both, I use HDMI to be able to drive a 1440p 240hz 10-bit HDR signal @ 30 Gbps.

  • I had said I wouldn’t upgrade from my RTX 3080 until I could run “true 4K”.

    I finally got the 240hz 4K uncompressed but it required buying a $1300 Asus OLED monitor and the RTX 5090. It looks amazing though, even with frame gen. Monster Hunter had some particularly breathtaking HDR scenes. I think it uses DisplayPort 2.1? Even finding the cable is difficult, Microcenter didn’t have them in April and the only one that worked was the one that came with the monitor.

I want to play games on the same fancy lg tv I use with my consoles. I just checked and it does not appear to have displayport.
