dual monitor, main monitor goes grey when browsing internet

December 24, 2015 at 22:07:19
Specs: Windows 7
I just bought an ASUS MG279Q and now run a dual monitor setup with that as my main and an LG Flatron W2243T as my secondary monitor.

I have a very fast/powerful computer, but when I do simple things like browse the internet my main monitor often goes grey suddenly, with black horizontal lines. Unplugging the monitor moves the problem to the secondary monitor and only restarting fixes the problem, although if I restart sometimes I can cancel the restart and it will be fixed. What causes this and what can I do to fix it?

Are both Monitors connected to a graphic extension board?
Or how did you connect both monitors.

Perhaps an update of the graphics driver may help.

Both monitors are connected to my graphics card, one through DVI the other through DVI dual link I think it's called. I already tried updating my graphics driver and that didn't do anything to solve the issue.

Additional information: I've found out that if I ALT+F4 the browser I have open when the problem starts, it is usually fixed. Don't know if that helps with the problem solving.

I have a 400$ graphics card that I'd like to continue to use but I think I have to scrap it if this problem persists.

Assuming you are not getting the issue with either gaming or graphics intensive programs with both monitors, so it should not be an issue with the power supply not being powerful enough for the graphics card/system. (Let us know if this is not a correct assumption.)

It may not appear to matter but most times including details on your hardware including motherboard, CPU, graphics card, power supply at the least, can help us find a possible solution.

Try reviewing your browser add ons and removing or disabling the ones you did not specifically install or want. Then clean out your browser (History, Cookies, etc.). Then run Malwarebytes to be sure you do not have makware causing your issue.

You have to be a little bit crazy to keep you from going insane.

This is my hardware:

Corsair CX 500W PSU
21 IntelĀ® Core i5-3470 Processor
MSI B75MA-P45, Socket-1155
Kingston DDR3 HyperX 1600MHz 8GB
XFX Radeon HD 7870 2GB GDDR5
Samsung DVD Writer, SH-224BB
Kingston SSDNow V300 120GB 2.5" OEM
WD Desktop Blue 1TB

And I had an external harddrive (Western Digital) that broke and then I took it apart and installed it into the PC to use as an additional harddrive.

Malwarebytes found some files that I had it remove, but no actualy malware. I'll let you know if the problem persists.

I just want to say also: Thank you so much for taking the time to help me with this issue! Could potentially save me much trouble and a lot of money! :)
