Dual monitor flicker / mouse lag

[chainz]

Hey guys, Not sure where to put this so here goes.

I have my dual monitor setup as follows:
ATI 5850 connected to 24inch BenQ monitor via HDMI
And 32inch TV connected via DVI to HDMI

Having a problem sometimes the TV will flicker, And the mouse becomes slow / laggy
If I move the mouse onto the 24inch screen the mouse responds fine but laggy on the tv. Refresh rate is set at 60Htz for both screens.

test with swapping leads,so hdmi on 32" and dvi to hdmi on 24" to see if its cable problem

guess your graphic card is overloaded.
have you tried with only one monitor connected? does it act the same?

I've been having the same trouble.

Z77 Extreme4
BIOS: P2.00
Intel Core-i5 3570K
G.Skill Ripjaws X F3-12800CL10S-8GBXL x2
Dual ASUS VS248H-P - 1920x1080@60

When dual monitors are connected to VGA and DVI-D, I have the same flickering on the screen. I didn't notice it all for the short time I had only one monitor connected only to DVI-D.

Intel's official statement regarding this issue is:
This issue is a BIOS issue specifically with the Memory Reference Code (MRC) version 1.4.0.0 or older. Please contact your system or motherboard manufacturer for a system BIOS update for your system or motherboard that includes MRC 1.5.0.0 or newer.
If you have a system with 2 or more memory modules and are comfortable with removing all but one of them so that your memory is in single channel mode, try and remove all but one of them and the issue will go away. This can be used as a workaround until you are able to update your system BIOS from your system or motherboard manufacturer that includes MRC 1.5.0.0 or newer.


DCP Latency Checker reports:
Some device drivers on this machine behave bad and will probably cause drop-outs in real-time audio and/or video streams. To isolate the misbehaving driver use Device Manager and disable/re-enable various devices, one at a time. Try network and W-LAN adapters, modems, internal sound devices, USB host controllers, etc.


Has anybody else encountered this issue?

Is it still hangs even after trying it with just one monitor it's a system problem. When that happened to me it was a virus that hit my pc.

I had disconnected one of the monitors for a while (around 30 minutes) and hadn't noticed the flickering or mouse stutter at all.
