So small update. I upgraded the firmware in my TV, changed the input name to DVi devices, disabled anything in the TV settings that looked like it could interfere, and played with the Adv timing and now I’m getting signs of lx5 support. The image flickers but can’t seem to stabilize for more than a second or two (just long enough for game audio to be heard briefly). Is there some combination of settings I could possibly adjust to stabilize the image?
Edit: I have a stable image in Lx5! I had to disable “Allow tvp hpll2x”. Just like with the other outputs I cant seem to get the correct aspect ratio. Also I have a tear running up the middle of my screen that won’t go away. Not sure what’s up with that.
