Ongoing HDMI limited compatability

cat: graphics/fb0/modes: No such file or directory

These are relative paths, most likely relative to /sys/class (don't know -- booted the Pine64 a few weeks ago the last time). You might succeed doing a 'find /sys -type d -name fb0' to know the prefix needed to chdir to or create absolute paths.

Thanks, when acting as 'smart hands' and troubleshooting using instructions from another person I tend to be terribly literal. Using the info you provided;

Code:

root@localhost:~# find /sys -type d -name fb0
/sys/devices/soc.0/1000000.disp/graphics/fb0
root@localhost:~# cat /sys/devices/soc.0/1000000.disp/graphics/fb0/modes
U:1920x1080p-0

Decided to get a bit more info using another method. I hooked my pi to the monitor and pulled EDID info. 

Code:

root@raspberrypioldpi:~# tvservice -s
state 0x120006 [DVI DMT (57) RGB full 16:10], 1680x1050 @ 60.00Hz, progressive
root@raspberrypioldpi:~# tvservice -m DMT
Group DMT has 4 modes:
          mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
          mode 9: 800x600 @ 60Hz 4:3, clock:40MHz progressive
          mode 16: 1024x768 @ 60Hz 4:3, clock:65MHz progressive
 (prefer) mode 57: 1680x1050 @ 60Hz 16:10, clock:119MHz progressive
root@raspberrypioldpi:~# tvservice -m CEA
Group CEA has 7 modes:
          mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
          mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
          mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
 (native) mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
          mode 5: 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced
          mode 6: 720x480 @ 60Hz 4:3, clock:27MHz x2 interlaced
          mode 7: 720x480 @ 60Hz 16:9, clock:27MHz x2 interlaced

Thats the simple stuff, attached is the output of;

Code:

root@raspberrypioldpi:~# tvservice -d edid.dat
Written 256 bytes to edid.dat
root@raspberrypioldpi:~# edidparser edid.dat > edid.txt

Also adding full pi serial console boot log.

Code:

root@raspberrypioldpi:~# cat /sys/devices/platform/soc/soc:fb/graphics/fb0/modes
U:1680x1050p-0

ATTENTION Moderator Note

Forum doesn't allow upload of files with the extension .log seriously? Might what to address that lol.

I will check out.

The extension .log file now allow to upload.
