I recently got a new screen and it will randomly black out for a few seconds

Hello,

I recently got a new screen, it is a black widow 4k monitor. I think part of the issue is that the aspect ratio for it is very bizarre. I was wondering if anybody had any fixes to this issue. The model number of my screen is BW43CGM4K120. My graphics card is nividia geforce rtx 3060. Sometimes when I’m playing games, or even just on the desktop screen, I will have a random blackout the last couple of seconds. I would say the blackout is from between 1 to 3 seconds, but sometimes I can get a few of them in a row where the screen turns on for about a second in between. I have already reinstalled my graphics drivers and that did not affect it.

    Okay, first of all holding the power button forces your machine to turn off, like yanking the power cord out of the back of the computer. Don't do that.

    I had the same problem with an RTX 2070 super. I tried swapping cables, I tried newer cables that supported HDMI 2.1, rolling back drivers, trying a different monitor and nothing actually helped. This was only happening when I used an HDMI cable with HDMI port on the card. The other monitor, which was plugged in to display port, never had an issue.

    My problem ended up being the refresh rate of 144Hz. I lowered it to 120Hz and still had issues. Then I lowered it to 60Hz and all my problems went away. It turned out to be HDCP renegotiation/EDID. Turns out when games and full screen apps, such as Steam, went full screen (not windowed full screen, but actual full screen), it would drop from 120Hz to 60Hz. This caused a renegotiation. Due to quirks in either the card firmware or monitor firmware (haven't been able to determine which), the timing gets off, so it renegotiates over and over and over, causing a random black screen and sound to cut out.

    120Hz and higher requires a higher quality cable and more precise timing, so if cable struggles to handle the speed or timing is off thanks to quirky firmware, then you'll have these blackouts. Usually, what happens is things will go black the instant you go full screen and then keep doing it randomly after that, because it never recovered.

    Hope this helps!

    Hello, my name is Jan and I'm happy to help you today. I'm sorry you're having this problem with your monitors. There are many possible reasons why the screen turns black. This could be due to drivers, background applications or display cable issues. Please try the following suggestions.

    1. If the graphics driver has been reinstalled recently. Try to power cycle/reset your computer.

    Press the power button for 10 seconds to turn off

    then unplug your AC adapter for 30 seconds

    then plug in your adapter.

    then start your device.

    1. In some cases the refresh rate is causing the flickering screen. Ensure the monitor resolution and refresh rates match the monitor's native resolution /refresh rates.

    Check the display settings.

    Right-click on your desktop background

    Select Display settings.

    And under "Choose Display"

    select the monitor on the list

    Under Display Information

    Click the Display Adapter properties for Display

    click Adapter Tab

    Click List All modes

    From the list select the native resolution and supported refresh rate of the monitor

    Scroll down then select Advance display settings.

    Ensure that the refresh rate matches the monitor's supported refresh rate.

    1. Try to perform a clean boot. Some applications can also cause these flickering issues. Or uninstall the application that has been installed recently.

    1. If the above steps don't help, consider testing the monitor with another HDMI cable. There are cases that which the display/HDMI cables are causing flickering, resolution, and refresh rate issues.

    Hello,

    I am having trouble with my new monitor, I got it a few weeks ago, and when I do anything on my computer it randomly shuts off for several seconds before coming back on. This is on a Blackwidow 4k monitor (bw43cgm4k120), and I am using a Nvidia GeForce RTX 3060. I just restarted, after completely installing the drivers with a tool I found in another thread (Guru3D's DDU) and installed the NVIDIA app with the drivers automatically found. The only thing I see that might be an issue is that in the Windows settings the refresh rate shows as 59.999hz and in the app it shows 60hz. Is there anything else I can try? (I also tried in 120hz aswell and it does not seem to affect the problem.
