Gigabyte Monitors and Refresh rate

[xMillerLiteManx]

So I have this problem where if I set my refresh rate to 165hz, my monitors restart/prr cycle every 30-60 seconds. They support 165hz according to gigabyte. I am using the display port for both, and I have HDR.full specs below.

AMD Ryzen 5 3600 

Gigabyte 3060 GDDR6 12GB 

Asus Prime B550-plus MB

XPG 3200 ram 

Windows 11 home 

 

As far as I can tell, the monitors are up to date, but I am honestly not sure as I am not 100% certain on how to update them outside of through to system settings. 

 

I only have this issue at 165hz.  I do not have this issue at 120 or 60hz

where'd the DP cable come from? it's actually incredibly hard to find reliable DP cables. i think that's your culprit.

the GPU and monitor can do the handshake no problem but the signal flakes out in between.

FURUI is the brand name, they are supposed to be DP 2.0 VESA certified. What cables should I be using? I will certainly try it out. But I have a hard time believing that just the cables would make both monitors power cycle at the exact same time.
