I have a 6.08 monochrome lcd:
https://www.panoxdisplay.com/html/produ … -82-1.html
The lcd is deteced and display image when connected to my pc but when connected to my nanodlp it does not. I have tried with both the "Normal" and "Non-Standard Monochrome" Display adapter settings and neither works. When I SSH into it and use tvservice the display is detected:
tvservice - s displays "state 0xa [HDMI DMT (87) RGB full 16:9], 1440x2560 @ 48.00Hz, progressive" which looks to be correct and
tvservice -l displays:
"1 attached device(s), display ID's are :
Display Number 2, type HDMI 0"
BUT when I try:
tvservice -d edid.dat
edidparser edid.dat |grep 1440 |sort -u
I get "Nothing Written!" (no info like "hfp:60 hs:10 hbp:35 vfp:4 vs:2 vbp:2 pixel clock:198 MHz")
I cannot
Any thoughts?

It is common problem with less known displays and nanodlp. I guess filling config.txt file correctly based on manufacturer spec sheet should make it works.

Shahin,
Thank you! I just realized there is an additional issue... in NanoDLP "HDMI Power On/Off" is not showing as an option. What would cause that?

It is removed as some displays does not come up after hdmi off/on. Anyway you can do it using syscall code on gcode box.

Can anyone recommend a good 6" monochrome lcd with board known to work with raspberry pi (with config.txt even better)? I have tried virtually every config I've found and none seem to work with my board/screen. I can edit the config and get tvservice to show all the correct display modes but HDMI on/off still isn't an option, NanoDLP doesn't display anything on it and the LED on the driver board flashes (it is solid when hooked up to my computer)
