    Question ASRock FM2A88X-ITX+ and Yamaha RX-S600 connection problem

    I have recently bought a ITX motherboard ASRock FM2A88X-ITX+ with AMD APU A4-4020 to build a small PC. My purpose is to have a media center player mostly to watch HD movie with HD audio with my Panasonic TV 55' and my Yamaha 5.1 audio amplifier. I wish to use the DVI for the video and the HDMI for the audio in this way:


    PC output DVI ---------> to TV HDMI input (using a new cable DVI - HDMI converter) for video signal (TV has only HDMI inputs)
    PC output HDMI --------> to 5.1 amplifier HDMI input for audio signal


    The problem i have is that a soon as i connect the HDMI audio cable, the video on my TV goes off, seems the HDMI has priority on DVI for video output, so i'm not able to use this connection.
    To overcome the issue i used the S/PDIF for the audio.
    I'm not happy with it because the S/PDIF has some limitations with DTS HD Master Audio and Dolby TrueHD which requires more bandwidth available with HDMI which I want use it.
    I didn't find an option either on the bios or Asrock software to manage video output priority using integrated graphics on the CPU like mine, i'm using Windows 8.1 Pro Media Center, with latest updates, drivers and bios.
    Anybody has a PC like mine with similar issue?

    Do you have the video driver for your board and CPU installed, the VGA driver ver:13.351.1007?

    When that is installed, there is no AMD utility listed in Control Panel for configuring the APU video?

    If nothing to configure the video exists from AMD, then use the Windows Display option in Control Panel. With two "monitors" installed, you are obviously in multiple monitor mode, but that needs to be enabled and configured.

    If you see an Advanced settings option in Display, that should be the AMD video configuration options.

    Hi,
    sure I installed all drivers with software that comes with the MB, but to do what you say works only if I have two monitor, I try that anyway to see what happens using the TV and another monitor and I found that the cable DVI to HDMI behaves in the same way, sometimes de image flashes on TV but i can't see a steady image. If i use straight cables using HDMI to HDMI for TV and DVI to DVI for the monitor then i get a normal image on both screen. Seems that i can manage the video output only if i use straight cables but with TV + monitor only. The combination of TV with DVI to HDMI + amplifier is not working..... here is the pic with TV only plugged without HDMI to amplifier, that's disappointing. Maybe i need a special DVI to HDMI cable to use it in combination with the amplifier, I need to consult an expert, hope there's one around here. Thanks for help.

    HDMI to amplifier

    ASRock FM2A88X-ITX+ no video output priority-amplifier-hdmi-connect-jpg

    Due to system will take amplifier as hdmi monitor.
    So we can see two monitor output as first picture.
    Based on your picture, the system doesn’t detect one of your device, so it show only one display device.
    We provide some suggestion for verify the no signal output:
    (1)Load BIOS default setting.
    (2)Install AMD chipset and VGA driver form our website for verify:
    ASRock > FM2A88X-ITX+
    (3)Change other HDMI cable for verify.
    (4)Check the audio amplifier setting.

    If any question, please feel free to contact us.

    Hi,

    My configuration is this:

    TV: Panasonic 55' Viera VT30 (Sharkoon DVI - HDMI 2m cable)
    Amplifier: Yamaha RX-S600 (Sony HDMI - HDMI 2m cable)
    I went further with my tests, now the problem is focused on the Yamaha amplifier, using the connection as yours above i get the video on TV always flashing (on/off/on/off), also if i use a monitor has the same behavior.
    When i disconnect the HDMI cable from PC to amplifier the image on TV or monitor gets steady and normal. Seems the PC has issue on identifying the Yamaha amplifier and thats why the video is flashing.
    Is maybe a compatibility issue?
    I try also using 2 HDMI different cables for the amplifier but same behavior, then I update also the Yamaha amplifier firmware from v.1.11 to v.1.13 but nothing changed, I try every HDMI (1-5) input of the amplifier but has no effect.
    I then try also different settings in the menu of the HDMI input in the amplifier but no luck.
    I hope it's a software or cable issue, i'm not willing to change my amplifier :(
    Thanks for your support!

    Default Re: ASRock FM2A88X-ITX+ no video output priority

    Hi all,

    I solved the problem, in the BIOS I changed the video share memory to "Auto" before it was set to 32mb because I wanted spare some system memory, so in this case I need more then 32mb share memory! I dont understand why.

    Anyway now it works as expected but it was not easy to setup the video settings because the amplifier acts as a Monitor and I cannot exclude it from the video otherwise I can't manage the audio, so I spent some time to find the right setup.

    I wonder why a HDMI device like the amplifier must act as a monitor, Plug & Play in Windows should be improved for such devices.
