I just got a new monitor as my second which i just setup with an HDMI. after that my main monitor with a g sync module wont allow g sync and nothing im doing is fixing this. The monitor is an Alienware AW3821DW and my gpu is 3090 on DP1.4 .
"Set up g sync" does not show in controle panel.
I've rebooted and reset to factory.
Done all i can think of.
