Asus VH238H Monitor Restarts/Random Black Out

[WUMBOWAMPAS]

Whenever I am in game, such as Rocket League or Rainbow Six Siege, my Asus monitor would just restart itself. (i.e. my monitor would turn black for a few seconds, then it would turn back on and display the video). Previous fix attempts include, changing from HDMI to VGA, cleaning monitor/dusting, turning monitor brightness down, and resetting the monitor (was told by Asus support to try that, but it did not work). The issue seems to only happen when it gets hot in my room like during the summer. I have tried to blow a fan onto the monitor but no results. Some other notes, I have an XFX R9 280x and an XFX 850w PSU. Also, the PC is still running and on my second monitor (not the one with issues) is still displaying the video during the Asus blackout. Any ideas?

It could be a thermal reset, but I doubt it. It sounds like a power problem to me. Do you have another power cable that you can switch out (the 110V component power cables are interchangeable) t. Make sure that the cable is firmly plugged in on both ends.

And lastly the monitor may be defective.

When switching the power cables, don't swap a heavy duty cable for a light duty cable. For example, don't swap your power supply power cable with your monitor power cable.

As for the cable swapping, I do not have any other power cable to switch out sadly. Also, when I occasionally clean my PC and moved stuff around, I may have switched the PSU cable with the monitor's cable. Is there anyway to figure out which is which by looking?

The heavier duty power cable is thicker and usually stiffer. Here is an example of a 14 AWG power cable.

And here is a lighter duty 18AWG power cable. This one is for something like a monitor.

Thanks for the links. It seems that I have the thicker "heavy duty" cable connected to my power supply and a lighter duty connected to the monitor. Any other ideas? Thank you

The only thing I can think of is a total reset of the monitor. Shut the system off (might as well unplug the PC too). Unplug all of the cables and power cord from the monitor for minute or so. Then plug the monitor cables and power cord (turn on monitor). Then plug the system power cord back in, and start the system normally. This will clear the apps running on the system and reset the monitor.

Since there are two monitors, it may be a display issue On the Windows Display screen, what is the Multiple Displays setting? I've had some trouble with the Windows Display before. For example one monitor going black (but it stays black until I fix the issue). I've had to go through the process of selecting a monitor and then duplicating that monitor on the second monitor. That generally fixes the problem. Plus I have to reset the monitor on occasion as well.

Got it. I will try this out when I have some time today. I will just select your response as an answer because it seems no one else could think of an issue. Thank you for your time to help me try to solve this issue.

I thought of one more thing to try. It may be a driver issue.

You can download the Asus VH238H Monitor driver here.

https://www.asus.com/us/Monitors/VH238H/HelpDesk_Download/

Uninstall the current driver in the device manager (for that monitor), then update the driver with the downloaded driver.

I don't know if it is related, but Windows 10 update is now updating device drivers. But the drivers tend to get screwed up in the process. I have had my audio driver replaced with a generic Microsoft driver that totally disabled my audio for a while. It has also screwed up my Nvidia graphics driver several times.

One last thought to try. Try this last, in the Windows Display screen switch the current primary display to the one that is having issues, then duplicate the other monitor. See if the problem moves to the other monitor. That will isolate the problem to Windows display not the monitor itself.

That pretty much runs the gamut of ideas. The last alternative is warranty repair (assuming it is still under warranty).

I'll try it out. Thank you.
