I have a CAC-1070 adapter plugged into a Nvidia Quadro k620, hooked up to an LG 49UH668V via good quality HDMI 2.0 cable.
After starting the PC, I get a signal on the TV but the screen stays completely black. After about 20 seconds it changes to a blueish tint and then the signal stops.
I have HDR disabled on all the HDMI ports on the TV.
Is there anything else I should check/do?
Your help is much appreciated.
