Install LE on HP t430 Thin Client - Problems

    1. DEVICE: HP t430 Thin Client; 2/16GB; Gemini Lake; Intel Celeron N4000 CPU 1.10GHz
    2. i tried with 'LibreELEC-Generic.x86_64-13.0-nightly-20240802-d20b714' and the nightly 'LibreELEC-Generic-legacy.x86_64-13.0-nightly-20240802-d20b714', both same
    3. connect the PC via HDMI at my TV, i see only the message with starts in 5 seconds, afterwards black screen (no signal)
    4. when i use my USB Dock (my workplace with monitor, keyboard,...) via USB-C, then i'm able to run and finish the setup
      1. BUT, after close the installation, i connect the PC to my TV and i see only the HP logo, then NO SIGNAL
      2. after add 'video=HDMI-A-2:D' at sysconfig.txt, TV output works
      3. i execute also getedid create, same behaviour
        BOOT_IMAGE=/KERNEL boot=UUID=xxxx disk=UUID=xxxx quiet video=HDMI-A-2:D initrd=/edid.cpio drm.edid_firmware=edid/edid.bin video=HDMI-A-2:D
        italics it's added manually by me
        the bold it's from getedid command
    5. PROBLEMS
      1. 4K ISO/MKV files not working; from HDD attached via USB; after press the file to play > black screen; with the Back button i'm able return to KODI
      2. 1K (FullHD) files ISO/MKV plays fine but no audio


    The t430 has 1x DP, 1x HDMI and 1x USB-C with DP.

    Code
    LibreElec:~ # tail /sys/class/drm/*/status
==> /sys/class/drm/card0-DP-1/status <==
disconnected

==> /sys/class/drm/card0-HDMI-A-1/status <==
disconnected

==> /sys/class/drm/card0-HDMI-A-2/status <==
Connected

    I set at BIOS the GPU memory size to 128M, beside this option there nothing about GPU. But it looks like that A1 is HDMI and A2 the DP.

    Code
    LibreElec:~ # ls /sys/class/drm
card0           card0-HDMI-A-1  renderD128
card0-DP-1      card0-HDMI-A-2  version


    Code
    kmsprint -m
Connector 2 (160) HDMI-A-2 (connected)

    I guess your PC has an LSPCon chip to convert from DP to HDMI. Those chips have known driver issues, and such issues are very likely unsolvable by us (search for "LSPCon" on the forum).

    Make sure your BIOS is up-to-date. If your hardware support page offers video driver updates, install the latest. They sometimes include firmware for the LSPCon driver. You probably need Windows to install those updates.

    What TV? Samsung?

    yes

    Goto General->External Device Manager->HDMI UHD Color (or Input Signal Plus on newer models) and disable it.

    Use the normal Generic image, not Legacy.

    WOW, thanks many times for this hint and for your help!

    After disable the mentioned option the KODI was appears immediately. I see under system > display > resolution 3840x2160p with rate 60. And now, the 4K movie runs fine.

    But i'll check further after apply the mentioned settings from wiki pages, like whitelist.

    Once again, THANKS!

    next question is raised ... w/o UHD Color no HDR is available.

    samsung shows the info only with UHD and the HDR label is missing.

    as i understand, only Intel UHD 620 and newer is with HDR?

    the UHD 600 is able to decode HEVC h265 8 and 10 bit, so it should have HDR?

    when i install the (none legacy) generic will i get HDR?

    1. BIOS with 1.16 is updated
    2. Windows 10 64bit is installed, but i'm not able to install the graphic driver, neither via setup.exe or via device manager.
      HP Support Assistence tool (automatic driver update) is also not running. i tried the driver from Intel too, without success.
      therefore Bacis Driver is installed from Microsoft (default driver)
    3. with Windows i'm able to turn on Samsung UHD Color with for the according HDMI output (but no HDR label is shown)

    However, as next i'll install the Generic LE, i'll report the outcome.

    the generic 'LibreELEC-Generic.x86_64-12.0.0.img.gz' is installed. HDR label is shown at the according 4K files. the samsung tv UHD color option is not working, like with legacy image, only when this option is disabled its working.

    1. the UHD color option is not working at all ?
      not even with the newest nightly build 13 ?
    2. my android tv (mibox) is with 3840x2160/60 and KODI GUI with 1920x1080/60.
      when i play a movie only the refresh-rate is changed, due to adjust option is enabled.
      the resolution keeps always the same, 3840x2160.
    3. at LE i set the GUI to 1920x1080/60 and at playing a movie resolution and refresh rate is changed.
    4. to make the same like [2]: add 'video=HDMI-A-2:3840x2160M@60' at sysconfig.txt ?
    5. what is difference between 'video=HDMI-A-2:D' and 'video=HDMI-A-2:d', upper and lower case Dd?
