[SOLVED] Titan x pascal and HDMI 2.1

[eliau81]

Hi all,
Just got a brand new LG C1 TV, that got a 4X2.1 HDMI ports.
I gonna plug it to my pc with the titan x pascal.
Can I benefit from the HDMI 2.1 at all?

i believe the Titan X is Maxwell based, while the Titan Xp is Pascal.

the Pascal version does not support HDMI 2.1, only up to 2.0b.

The Titan Xp (pascal) is only HDMI 2.0b compliant.

What specific benefit are you looking to achive by using an HDMI 2.1 card?

The Titan Xp (pascal) is only HDMI 2.0b compliant.

What specific benefit are you looking to achive by using an HDMI 2.1 card?

With that TV 4K 120Hz HDR with VRR.

you will only get 4k 60hz sorry the card simply can not output at 120hz 4k

It is possible, with a big BUT - https://www.benq.com/en-us/knowledge-center/knowledge/4k-120hz-gaming-monitor.html
Reducing other quality settings to achive 120Hz isn't a good solution.

You could try an adapter but this is also a long shot. It looks like some DP to HDMI adapters are specifically made to get 120Hz at 4k but the GPU needs to be DSC 1.2 compliant. Now we get back into gray area. The Titan Xp is DP 1.4 'ready' and DSC 1.2 is part of the DP1.4a specs but I wouldn't bet that it would work. Too many ifs and maybes involved. Here's an example of the adapter, if interested - https://www.amazon.com/Club-3D-DisplayPort1-4-Adapter-CAC-1085/dp/B08BX49V5V
