I am helping a friend interface an HDMI LCD display to a Pi. The display is borderless and a specific size to replicate a flight simulator instrument panel. I have tried creating a custom resolution but without success. I can't get a stable display at all. I get a flashing backlight or if anything is displayed it is intermittent and repeated across the panel.
The display will work on a PC graphics card (GTX1080Ti) with the following settings:
- 720 x 1280.
- 8 bit.
- Colour Format RGB
- Colour spacing SDR.
The display itself is a: Sharp LS060R1SX01.
The driver chip is Toshiba 358870XBG.
So far we have failed to find any detailed data sheets for the Sharp display.
I think it's default resolution is 1440 X 2560 which is probably too much for the Pi but I can't even get a custom setting to run:
Amongst other settings suggested on this thread I have tried even standard 16x9 resolutions. I also tried:
hmdi_cvt 1440 720 60
I can't find any timings info for the display Does anyone have any ideas or suggestions?
