I have a 4k headset in the 100xxxx series that has previously worked. However, after restarting the headset after a display issue (alternating black horizontal lines on the upper half of the displays), it now only shows black, except for some bad pixels. The backlight turns on, in mirror mode everything shows as intended, diode shows blue, flashing appears to work. I've reinstalled Windows 10, tried latest Piplay as well as older, pulled out other displays, pulled out and reinserted USB, tested 1920*1080 mode etc. to no avail. The only thing I haven't tested yet is using the hacked FW, only because I haven't figured out which one it is.
Several threads appear to have resolved similar issues, but I haven't found a good answer to how in several of them.
Any tips on what I'm missing or is it possibly a hardware issue?
