I recently bought a Hyperpixel 4 display for a Raspberry Pi.
I plugged it in, loaded the drivers but I get no image.
The unit has never shown any usable image.
If a Python script is running that outputs to the main HDMI screen, the Hyperpixel shows a dim, smeary and unreadable image.
The screen layout utility shows the HDMI and a new DSI-1 entry.
The DSI1 entry has FIXEDMODE for Resolution and 60.06 Hz fixed for frequency. I cannot change either.
If I do a i2cdetect -y 7 I get - - in all positions except for address 5D where it says UU
Can you help me sort it out please?
