    At random, screen would go blank for a few seconds then come back.


    Windows 10 Enterprise LTSC 1809 x64
    AMD Ryzen 5 2400G @3.8GHz
    MSI B450M PRO-M2 V2 MicroATX/current BIOS
    16GB Corsair Vengance LPX DDR4-3200
    Radeon Vega 11 Graphics/current drivers
    Dell SE2717H 1080p 1920x1080 @60Hz using HDMI

    At random, screen would go blank for a few seconds then come back.
    Swapped HDMI cable for another one and problem was still there.
    Swapped HDMI cable for VGA cable and issue went away.
    Thought something was wrong with the Dell HDMI input.

    Just got a Lenovo ThinkVision P27h-10 QHD 2560x1440 @60Hz using HDMI.
    Guess what? The problem returned!Wasn't the Dell monitor after all!
    Have current drivers from Feb 2021.Is this an issue with Win 10, AMD or anything else?

    Seriously thinking about going back to Intel CPUs.....

    Sounds like the HDMI connector on your motherboard is shot, or possibly just loose.

    They make HDMI cables with a locking heads. You might try one of them.
    But if the HDMI connector on the motherboard is damaged, that may not even help.



    As you can see from this pic of your motherboard, the HDMI connector is pretty fragile.

    I jiggled the HDMI cable at the back plate of the MB while watching the monitor and nothing happened.

    It could be the HDMI circuits on the motherboard, also.
    If it was the APU (CPU), it would happen on the VGA as well.

    You eliminated the monitor, and the cable. What's left?

    The motherboard connectors (HDMI, and VGA) or the associated circuits.
    I don't know, when, in the circuits, they split the VGA and the HDMI. I would assume it's right before the connectors.

    We also don't know the accuracy of your wiggle test. It may be up and down, side to side, in and out... etc.

    The fact that it's "random" pretty much rules out thermal compound on the CPU pins.
    If it was intermittent on a "pattern", that might point somewhere else.

    A pattern like... whenever you open a certain game, or program. Or perform a certain task.


    I mean there's the off chance you could just have two bad HDMI cables. I wouldn't bet on it.



    /edit

    I guess it could have something to do with the driver also. Did you have the problem before the latest driver?

    @ncsercs


    You started this thread approx. 3 hours ago. How long have you had the problem?
    What changed between when you didn't have the problem, and when you first noticed it?


    I noticed you mentioned "latest" driver in Feb 2021... might want to try an older driver.



    DDU Instructions - AMD
    1. Get this program, here: Display Driver Uninstaller (DDU) | Wagnardsoft ...get the latest version, and save it to your desktop.
    2. Get your vid card driver here, use the Manual Search: http://support.amd.com/en-us/download ...save this to your desktop.
    Unhook the internet completely.
    3. Reboot into Safe Mode and run DDU (Display Driver Uninstaller) choose the "Highly Recommend Option", and just do what it tells you.
    4. After it's done, reboot to normal mode, then just double click the AMD driver to install. If it want's to reboot, let it.
    Rehook the internet.

    I had this problem for awhile and was using the VGA cord to get by.

    This was the driver I was using which did work for a while when all of a sudden this started occurring. Same HDMI cables.

    "radeon-software-adrenalin-2019-19.8.1-minimalsetup-190820_web"

    Tried the Feb 2021 driver in hopes it would fix it. It didn't.

    Have other people had this problem?

    I'll try your suggestion tomorrow. I'm exhausted.

    Lot of folks have had issues with AMD drivers, in general.
    Sometimes, with older equipment, going back to an older driver helps.

    I would suggest a driver closer in age to the system... maybe a 2018 driver?

    Also, we just had a Windows Update. If you don't have drivers blocked, sometimes a driver comes with the update and corrupts the one you have. That's what DDU is for. It completely removes the AMD driver and gives you a fresh start, so to speak.

    It's also used for Nvidia drivers for the same reason.

    Most important though is to try and remember what changed/when... and cause the problem to occur.

    Tried DDU and several drivers from mid-summer 2019 which is when I built this.

    Lets face it. Win 10 + AMD cpus + AMD drivers = crap.

    I've been looking at an Intel I5-8400 and an ASUS PRIME B360M-A

    Thanks for all your help but I think I'm going back to Intel. At least their GPU drivers work.

    Guess what? When the glitch occurs, I give the case a 'whack' and the screen display returns much quicker!

    I'm beginning to think it's something in the MB.
