1920x1080 Resulution on HDMI

    I try to use a standard PC-Monitor (DELL U2410) on the HDMI port as a display. I use the command


    HDMICFG -hdmi off -grp0 off -hdmi on 6 -grp0 on


    In the end the result is not satisfying: My display is detecting the 1080p mode, but the desktop is never the less limited to 1024x600, that means it just fills about a quarter of my display.
    If I open the FSBoardConfig utility I see the display resolution as 1024x600.
    How can I make sure that I get the whole resolution in the desktop and for my programs as well?


    Do I have to make some changes in the registry?

    I am not sure but I think the primary surface size is defined by the primary display driver. Therefore you may need to adapt the display settings in registry under [HKLM\Drivers\Display\LCD].
    E.g:

    Code
    1. [HKLM\Drivers\Display\LCD\mode17]
    2. PPL=dword:1920
    3. cols=dword:1920
    4. LPP=dword:1080
    5. rows=dword:1080


    I have tried this currently without success. It might be possible that the resolution for the primary display driver is limited. I have forwarded your request to the responsible developer that will be available at next week.

    Sorry - there was a typo in my previous post. It should be columns instead of cols. FullHD should work poroperly with following settngs:.

    Code
    1. reg open \drivers\display\lcd\mode17
    2. reg set val columns dword 1920
    3. reg set val PPL dword 1920
    4. reg set val rows dword 1080
    5. reg set val LPP dword 1080
    6. reg save


    This will work generall, but as driving this huge resolution on primary display interface might produces unnecessary system utilization in your application it will be a advisable to reduce this system threshold. In simplest case by reducing framerate for example.
    I will discuss this with my college anyway and inform you in this thread.
