Hi!
before you tell me that gsync over hdmi does not work on 10 series card but only on 16 and RTX listen to my story I had my PC connected to 3 monitors on my desktop and TV on the other side of the living room and after upgrading TV to LG C9 i was happy to see it as Gsync monitor but as I was lacking display ports on my pc, I decided to upgrade and to build second pc dedicated for TV and VR, so I've upgraded my main pc to 2070super and moved my 1070 to tv pc. Here is where I've noticed a problem - Gsync opction was nowhere to be found in Nvidia control panel after googling problem for some time I was surprised that it doesn't suppose to work.. but IT DID! So after some troubleshooting and moving pcs i know now that gsync on OLED is possible on 10 series card in two ways - Nvidia Profile Selector (i saw some quick video but it doesn't work for me as profile selector has unhandled error) and (as in my case): Gsync over HDMI on supported monitor/tv does work IF there is Gsync monitor connected (not even selected/turned on) through DisplayPort at the same time...
Is there anyone there who knows how to emulate such situation? I don't have option to buy gsync monitor just for this purpose as my spending has already exceeded my toy budget for couple of years
