    Lose HDMI signal when Win7 boots up


    New build WIN7u64 updated.
    Mother board --Asus A88X-plus
    CPU--AMD/APU A10 6800
    8GB duel mem
    630watts PSU
    Asus 1080 monitor.

    New Win7 install , normal, install any version AMD catalyst drivers reboot..
    after windows logo, screen go black, windows still loads to desktop.
    monitor loses signal...stand-by,, black screen. repeat, then stays on stand by.

    reboot safe mode. uninstall HD display adaptor ..reboot. IT installs Standard VGA driver.
    works fine, still can do 1080 resolution. but not as it should be. in High Definition

    AND tiny red dots appear, mostly in dark areas and in videos.

    I have tried 2 APU's, both get same results.

    PLease any input will help. Im new to this.

    Hi Dexxmann, welcome to Windows Seven Forum.

    Have you loaded the software for the monitor, or it may need a driver update.

    Is this the only monitor connected to your computer, if it is you could try using the DVI connection instead of the HDMI one. The DVI connection is generally preferred as the better option.

    I checked the asus web site ffor drivers for my monitor. all it had was for muti monitor.
    i do play PS3 with HDMI hook up. everything runs fine. I thought it was the cpu/apu, so i sent it back and bought another one, same thing. now im sending back my mother board.
    my monitor dont have DVI connection. my friend said something about a DVI adaptor, from HDMI to DVI so i can use DVI on the computer and HDMI on the Monitor/ no sure? any thoughts?

    I used your monitor model details that you posted in Post #4 & did a web search & there is a driver listed for your monitor. I would down load this update from the ASUS website closest to you & install it.

    Version V1.0.22
    Description ASUS MultiFrame Software
    For ASUS monitors only

    What driver does Windows 7 want when you enable Automatically deliver drivers via Windows Update (Step 3) and then Check for Updates, install all Important and Optional Windows Updates until no more are offered after reboots?
