So I hooked it up to my windows machine and did an EDID dump and here is what I got: DumpEDID v1.06 Copyright (c) 2006 - 2017 Nir Sofer Web site: http://www.nirsoft.net ***************************************************************** Active : Yes Registry Key : DISPLAY\LZT0001\5&abb2a63&0&UID4352 Monitor Name : LS060R1SX01 Serial Number : 00000000 Manufacture Week : 12 / 2017 ManufacturerID : 21555 (0x5433) ProductID : 1 (0x0001) Serial Number (Numeric) : 0 (0x00000000) EDID Version : 1.3 Display Gamma : 2.20 Vertical Frequency : 23 - 75 Hz Horizontal Frequency : 15 - 240 KHz Maximum Resolution : 1440 X 2560 Support Standby Mode : No Support Suspend Mode : No Support Low-Power Mode : No Support Default GTF : No Digital : Yes Supported Display Modes : 248 X 155 60 Hz 1440 X 2560 60 Hz ***************************************************************** Looks like the driver only supports these two Resolutions and when I do h3disp I get the following supported resolutions I guess this means the driver does not support scaling? Any advice on how I can add support for this screen?

Ok I can try that and see what it says. Is there a way to check it on the Nano Pi M? I wanted to make sure the adapter is being detected by the OS. My bootup screen does not show me anything about whats happening with the HDMI. I just see "vcc-hdmi-18".

Yes I tried both -d and -c "full scale color".. Did not fix the issue. Is there a way to check the HDMI EDID to see what the adapter supports? Also I have hooked the LCD screen up to my Windows PC as a second monitor and adjust the screen resolution up and down and it seems to work just fine.

Hi Guys, I bought one of these pcDuino 4 (Nano Pi M1) boards: http://www.linksprite.com/pcduino4-nano/ Works great with Armbian Legacy Kernal. I got this screen with the HDMI + DSI Driver Board. Works fine with normal PC -> HDMI output but will not work with the Nano Pi.. https://www.alibaba.com/product-detail/LS055R1SX04-1440x2560-5-5-2K-LCD_60672828148.html?spm=a2700.7724838.2017115.1.3c93b095HGc0XS The LCD screen just turns on then off and on and off forever. It never locks on to the HDMI signal. The Nano Pi M1 works just fine with a regular monitor but not with the LCD/Driver combo. I have seen some purple images come up on the screen and sometimes I can see 4 desktops on the tiny screen just for a split second. I have also tried multiple resolutions using the h3disp command. Not sure how to debug this issue. I have tried using multiple power sources, different HDMI cables, with no luck. Any help would be awesome. I am new to Linux so I am just not sure how to figure out what the issue is. Thanks You Jay
