I was trying out the hdmi expansion card and could not get it to work with my LG CX OLED TV at all. The TV doesn’t detect any signal. Tried with both windows 11 and linux (fedora 42).
At first I was worried maybe I had a dud HDMI card (after seeing some other posts with people getting them replaced frequently) but I went and tried with my computer monitors (Acer xv275k and an LG something or other) and it worked fine there. Just doesn’t seem to want to work with the LG CX TV (which, i mean isn’t that basically just a monitor?)
Any ideas what I’m missing. I tried both the usb-4 (back expansion slots) and the usb-3 front slots and no luck. With the computer monitors it just auto-detected the displays and just started to work automatically. With the TV the TV flickers then no signal.
I tried forcing display detection, but not sure what else to try?
Oh this is with a new AI 9 HX 370 framework 13.
