LibreElec on RP4 resolution problem

1st Official Post

    I’ve installed the latest version of LibreElec (9.2.0) and am using it on a Raspberry Pi 4 computer. For some reason when I connect to my TV (1080p) via HDMI, the resolution is only showing as 1024x768. If I go into Settings > Display, 768p is the highest resolution available.


    I’m also not getting any sound.


    For the record I’ve tried multiple combinations of hdmi sockets on both the RPi4 and the a TV to no avail. As I understand it, the hdmi socket nearest the power cable is the one to use on the RPi4.


    what am I doing wrong. How do I get it to display in 1080p. I’m sure it’s something simple, but I’ve been tinkering for a while now and just can’t seem to figure it out. Any help or suggestions would be greatly appreciated.

    I haven’t tried a different cable yet, as I only have the one hdmi mini cable. For what it’s worth it’s the official RPi one.

    I bet it's the HDMI cable, because your 1024x768 is a typical PC screen resolution. Buy a High-Speed Micro-HDMI to HDMI cable, or an adapter to use a standard HDMI High Speed cable. HDMI High Speed is an official standard, made for high resolutions.

    I’ve just ordered another cable, which should arrive next week. I’ll report back once I’ve tested it.


    Although I would just mention that the cable I’ve been using (the official RPi cable) does have “high speed HDMI” written along it.


    For what it’s worth, I downloaded the latest version of Raspbian Buster (kernel 4.19) and tried that on the RPi4. Sadly (and perhaps not surprisingly) I had the same problem.

    You could connect your Pi 4 to another TV to see if it works normally. If you don't have another TV, maybe you could connect it to a neighbor, friend or relative's TV for a quick test.

    I had the same problem with sound and resolution. I fixed the sound with the solution mentioned here:

    No HDMI Audio

    Also , is it possible that raspberry trying to use the TV's bluetooth speakers if available ? (not tested)
