Dual Monitors Crash issue

Hi,

I am running Windows 8.1 with a AMD Radeon HD 7970 GPU.
Drivers are up to date (14.501.1003).
I am using no other software for managing dual monitor configurations.

I have the following two monitors...
Asus VN247 DTV HDMI 1080p @ 60Hz (Primary Monitor)
Connected via HDMI on monitor to DVI on GPU using a HDMI to DVI cable)
Available Connections: Dual HDMI, D-sub.

BenQ FP91G+ DFP DVI 1280x1024p @60Hz (Secondary Monitor)
Connected via DVI on monitor to DVI->HDMI adapter to connect to GPU.
Available Connections: DVI, D-sub.

I'm using Internet Explorer 11 with all settings default.

ISSUE:
I use both monitors and switch to using them as an EXTENDED desktop using the Windows key and pressing "P". And then choosing EXTEND.

When I watch any videos on YouTube on the Asus monitor the Asus monitor will go red with thin red lines vertically and horizontally across the monitor. The BenQ monitor remains ok and the rest of the system appears to be unaffected.

I usually have to reboot the system to correct the issue. Usually after a reboot if I go to watch YouTube again it is often unaffected and plays fine.

Can anyone please suggest what might be causing this issue as it is really annoying, thank you in advance.

Does this happen when you remove BenQ too?

Another thing I noticed (unless I am getting it wrong):
Why don't you use HDMI to HDMI for the ASUS, and DVI to DVI for BenQ?

Thanks for your reply.

The problem never existed until the BenQ monitor was introduced recently.

Shortly after making this post the connections was changed to make them native to give that a try as you suggested.
And I thought it had fixed it... but it seems to have made it worse because now when it does happen both monitors have the problem I described.

After trying out Carwiz's suggestion..

Try:
Un-plug the PC and monitors from the power mains for a minute or two.
Remove BenQ, keep ASUS as HDMI-HDMI.
Load defaults in BIOS (either first screen or exit menu).
Report back.

Hi,

As I mentioned in my OP. There is no issue in single display mode.

UPDATE:
Disabling Hardware monitor was done on IE but this did not resolve the issue.
The screen turned black instead of red.

Just wondering if a single monitor setup is still working alright, just because it was alright doesn't mean it is now. And that would help diagnosing (may be totally irrelevant too, but have to try).

Can you disable flash (better uninstall) and run Youtube with HTML5? Does it happen that way?

Does it happen with other browsers? Firefox Portable - Mozilla Firefox, Portable Edition | PortableApps.com - Portable software for USB, portable and cloud drives
