    My apologies for the delayed response. I'm not sure if updating the firmware or my trying hdmi_mode=5 rather than 16 but I've got Raspian desktop in full glorious 1366x768. In case this helps anyone else in the future I'm using the following settings in config.txt

    framebuffer_width=1366

    framebuffer_height=768

    hdmi_force_hitplug=1

    hdmi_group=1

    hdmi_mode=5

    hdmi_druve=1

    After transferring these settings to LibreElec's config.txt, I'm very pleased to say we have lift-off.

    Thank you both for your time and trouble.

    Hello Hiss,

    Good catch, unfortunately no joy in LibreElec-ville. I tried your suggestion by replacing http://start.elf/fixup.dat and commenting out the hdmi_drive/group/mode but upon reboot, I got no video at all, just a black screen. So I re-added the hdmi_drive/group/mode, which gave me the splash screen and then a black screen as opposed to the http://pre-start.elf/fixup.dat which was the splash screen and then garbled (similar to my original photo).

    So I guess these changes could be considered a half step forward.

    ...and I continue to make progress. I added the following lines to the config.txt:

    hdmi_drive:0=2

    hdmi_group:0=1

    hdmi_mode:0=16

    Now when I boot, I see the title page/Libreelec logo but the screen get garbled when (I assume) switching to Kodi.

    I recall reading something about modifying some Kodi configuration XML file to fix these problem but I don't recall where. The quest continues...

    Edited: I'm stuck now. I found what I think are incorrect values in the kodi guisetting.XML but every time I reboot my changes are reverted.

    Help?

    Hi (again),

    I appear to be making some progress. After putxing about with tvservice, I've managed to get the following. Only problem is that the screen stays black for a while and the tv's firmware kicks in reports "retrieving data". I think the problem is mode 81 wants 60Hz and TV service -s is reporting 59Hz.

    LibreELEC (official): 9.1.002 (RPi4.arm)

    LibreELEC:~ # tvservice -s

    Hello Hias,

    Well there's good news and bad. First the good; adding ssh to the cmdline.txt file did indeed fire up the ssh server and allowed me to access the system.

    Now the bad, all three 'tvservice' commands appeared to hang the ssh session and offered no output at all. As for the journalctl -a & kodi.log. I'm not familiar with the 'pastebinit' command but I assume it has something to do with the pastebin service. Unfortunately this setup has no internet access, so I've uploaded the output from those commands to my Google drive and offer links to them, rather that try and post a wall of log files here I hope that's acceptable.

    Output from journalctl and kodi.log and edid.dat

    I very much appreciate the help.

    Thank you again

    Update: I noticed in the journalctl output something about "consider forcing hotplug if HDMI is attached", so I enabled hdmi_force_hotplug=1 in the config.txt file ane rebooted. Unfortunately I am not getting any video output, not even the garbled screen but I do get information from the 'tvservice' commands now:

    LibreELEC:~/.config # tvservice -s

    Hi Folks,

    I'm new to the forums and LibreElec in general. I'm having a problem getting LibreElec working with my Raspberry PI4B and my old Sharp Aquos (1366x768@60Hz, ~2011, based on firmware date). I've tried flashing the (and I realize it's still Alpha) previous (Alpha-001) and current (Alpha-002) version of LibreElec for the Pi4B with Etcher, the LibreElec flasher and Win32DiskImage on several different sdcards. These are completely fresh installs, no modifications to the config.txt. The results are I can see the software booting up based on the irregular flashing the PI4's led, which after a while stops flashing however I'm getting this from the tv and even though I've used nmap to ensure I'm trying to SSH in to the correct ip address of the PI4, I only see port 80 open, there's no ssh server running. My router is configured to issue a static IP to the PI4's mac address and pinging the Pi4 works.

    I'm stuck and could use some assistance as to fixing the problem.

    Thanks for taking the time to read my ramblings:?:

    Edited: Afterthough, I've tested the Pi4 with Raspbian desktop version and that work, so I know it's not a hardware issue. Thanks
