Windows 10: extended monitor going black randomly

Hello


I have a problem that is very stressful for me. After Windows 10 update (before update log in screen wasn't blurred, now i have version 1903) my extended monitor (samsung C27F390) started to blink black screen. I have this problem only on my extended monitor. I changed HTML cable, didn't work, didn't change power cube because when it goes black i still have signal and monitor stays turned on. I have latest updates both in my monitor and in my Intel HD Graphic 530 card. Only when i play games this problem does not exist (R6S) but when i play Brawlhalla it is still a thing. At this point i don't know what to do please help me. On log in screen (blurred) i don't have this problem either.


Did you ever had this problem?


What shuld i do?

:)

 

Monitor is going black or distorted white randomly

I have a LCD monitor on my computer. Randomly, the monitor will either go completely black (as if powered off, and the power light turns off) or it will get a distorted frozen white screen (like how your smartphone would look if you dropped it in a toilet and tried to turn it on). Not too surprising, I have not dropped this 21 inch monitor in a toilet. The only way I can get the monitor to work again is by unplugging it and plugging it back in

I'm pretty sure that it is just a dead monitor that needs to be replaced, but a friend suggested that it might just be the power cord, since the monitor will work (like it is now) for hours on end, then suddenly start randomly not working. It's worth checking out, but before dropping money on a new monitor (if it isn't the power cord), can anyone confirm (or strongly suggest) that it is not a CPU issue or video card? Or maybe someone has seen this before?

extending monitors

Hello,

I hope I can help you today

solote allow two monitors but here I leave this possible solution

Step 1

Connect a monitor to the normal video card, using the necessary cable (DVI, VGA or HDMI). This will be the main screen, so place it directly in front of your computer's cabinet.

Step 2

Connect the second monitor to the alternative port of the video card, and then restart the computer. The PC will automatically detect the second monitor.

Step 3

Go to the "Show options" window by right clicking on the desktop, then select the "Properties" option. From there, click on the second monitor (which will appear in the drop-down menu), and then activate the "Extend my desktop on this screen" checkbox.

Step 4

Connect the third monitor to your original video card (if it has three outputs) or to another video card, and then restart the computer one more time.

Step 5

Go to the "Show options" window by right clicking on the desktop, then select the "Properties" option. From there, click on the third monitor (which will appear in the drop-down menu), and then activate the "Extend my desktop to this screen" checkbox

regards...
