    Need RELIABLE HDMI video card that won't default to vga port


    I have several older (not too old GX620, 755 etc.) dell optiplex desktops that I'd like to use as linux servers attached to an LCD TV that only has HDMI inputs. I am having problems finding a video card that will output video upon boot to HDMI. I have tried GEFORCE 8400 and Radeon HD 6450 and both work fine when connected to a VGA monitor but the HDMI connection either does not work on boot up or decides to blank out (I get no signal on the TV) at random times. VGA does me no good - I need HDMI for this to work. I have tried several distros - CENTOS 6.4, Fedora 16, Ubuntu 12.04 and 13.x and all have similar outcomes.

    Are you connecting HDMI to HDMI? What TV?

    Have you checked the options in the BIOS?

    HDMI is connecting to a TV.

    BIOS is not a problem - the PCIE card works but only through the VGA port (not the HDMI port).

    But what is the connection to the computer? What Brand and model TV?

    I don't think this should matter but it is a Vizio LCD TV. The same card in the same computer works without problem when running Windows 7 or 8. I want to be able to connect multiple machines to a single hdmi monitor (or TV).

    Well, you didn't mention it worked with Windows.

    So now it would make me think it is a driver problem.

    Have you tried different drivers?

    Yes - I've tried both proprietary and open source drivers for AMD and Radeon chipsets.

    I personally would try some different distros until I found one that worked, then I would look for different cards, if that didn't work.
