No problem, was in the same situation as you and tested everything I could, the cable was the issue from the beginning lol.Thanks! I guess it's the cable. It does G-Sync only @ 1080p. :(
When I switch to 1440p & 120hz the screen goes black a few times and ends up with a super low resolution, something around 800x600.
60Hz works well even at 4K but no G-Sync.
I'll order a new cable today!
Right, makes sense. Do we know if next gen Nvidia cards will have it?
With the old cable I just got a black screen and that was it, at least you get a low resolution picture.
If you have your new cable, and you have everything enabled, the LG should tell you it switched to Instant Gaming response, and then you only have to enable it in the NCVP under Desktop resolutions, G-Sync and 1440p I mean.
And you're welcome.
