Monitors and Memory

Hi.
I got recently this monitor:
Samsung QLED 49" Odyssey G9 C49G95TSSR 1ms 240Hz

On personal computer i have set it to 240 hz (settings in the monitor menu)
However, when i try changing the refresh rate to 120 / 240 hz the monitor goes blank.

So how else do i operate on 240 hz?

I have geforce 3070 Ti and DP 1.2 cable 5m long.

I also notice that sometimes when playing a game the video flinches and I get the notification in top left corner of DP connection (as if the cable was loosing signal).

Can any1 help?

Your cable is 1.4 and NVIDIA calls for 1.4a which had improvements to DSC which you need to run with the 3070 gpu.

Aside from 1.4a which  is now an older DP spec you could probably use a newer DP 2.0 or 2.1 cable.

ok i changed my order to DP 2.0.
I was not able to find 2.1 DP cable (only HDMI 2.1)

anyway this monitor can only use DP 1.4 connection.

I have additional question.

somehow you found what specification my GF card has.

Can you find those details for t2000 geforce? its a quadro card.
Cos im using this monitor also for work, and im not sure if getting new cable (HDMI 2.1) has any merit to it.

Don't be lazy, go to NVIDIA.com and look it up yourself.
