Hello everyone,

I recently bought a new 24 '' 1ms screen, the benq RL2455hm. I connected it to my laptop and had no problems with it at all. After 2 months or so, I built myself a new computer. A gtx 970 4G with an intel i5 6600k proccesor running on 550W. I connected my new pc to my screen and now suddenly I get a black screen now and then for 1 - 2 seconds and then it comes back on. Everytime my screen goes black and comes back on, I hear a noise from my screen it sounds like knocking sound 7 times in a row real fast.

I didn't had this problem when i connected it to my laptop, anyone know the problem?

Oh, and sometimes it doesnt go black a whole day. and sometimes only 2-3 randomly.

It happens in-game and also when im not gaming like now while i'm making this thread.

Hope someone can help me and my apologies for my English :).

This might help someone. Had the same issue, which started happening after I had to move my desktop for cleaning. Random black screens then back to working. After some head scratching and much beard stroking it turns out the HDMI cable was loose and the mouse cable was knocking against it during some fancy Black Ops 3 mouse action. Thankfully nothing serious.



No it didn't have that issue when connected to my laptop.
 


It's also happening with another monitor, im using the same HDMI cable tho.. maybe if I replace that one....but it didnt flicker before when connected to my old pc which was just recently..

If it's a video card issue, what might the problem then be? is it restorable or do i jsut have to buy a new gpu
 
The problem is it happens very oddly, somtimes not in 7 hours or a whole day. and sometimes 10 times a day back 2 back. And it doesnt matter ifi m gaming or not...
 
Oh I forgot to mention that when I change my screen resolution, it has the same effect (1-3 secodns black and noise) as when it randomly goes black for 2-3 seconds...
 
is not a monitor issue as it happens to other monitor. does your desktop also has onboard video to isolate the problem even further tho I still think it is the videocard? what windows version are you using on the desktop & are you using the latest driver for the videocard?
 



Im using windows 10 and my video card is updated to the latest version. My desktop has a Intel HD Graphics 530 onbaord gpu..

Had a similar problem, fixed it by turning off hardware acceleration in my browser, worth a try.
