So I had Forza Motorsport 7 installed on my PC a few months ago, at the same time I bought a LG OLED65B7V which I connected to my NVIDIA 1080TI on HDMI while my PC Monitor is connected via Displayport. Everything worked fine and HDR worked fine with my LG at 4K resolution.
I installed Forza Motorsport 7 again yesterday since I got a new SSD a while back and didnt install it after that.
Nothing else than the SSD has been replaced, TV settings, PC settings etc are exactly the same as when everything worked fine a few months ago.
But now when I enable HDR in Forza 7 the colors gets really messed up and it only happens at 3840 x 2160, if I go down to a lower resolution on the LG TV the HDR works fine.
Has anyone else experienced this issue?
