Intel HD 4000 Graphics (i7-3770K) occasional flicker

[idata]

I have an i7-3770K on an Asus P8Z77-V PRO and am using the on-board Intel HD 4000 Graphics to drive two displays.

My displays are a Dell 3008WFP at 2560x1600 on DisplayPort, and a Dell 2407WFPHC at 1200x1920 (rotated 90 degrees to portrait) on DVI.

Running the latest drivers (8.15.10.2761) on Windows 7 Ultimate N x64.

32GB memory, water cooling, Intel 240GB SATA3 SSD and a 750W Corsair PSU round out the box.

When working (writing code, web surfing, watching video) on the machine, the video will quickly cut out on one monitor or the other and then come back. The 24" Dell on DVI handles this [in a small fraction of a second] like a champ and I hardly notice. The Dell 30" looses the signal, goes blank and then takes a couple seconds to reacquire the signal before showing the desktop again... it's REALLY annoying!!

Anyone seen something like this before, or have ideas?

I've changed the DisplayPort & DVI cables, tried a different motherboard of the same model, tried a motherboard from a different manufacturer (Gigabyte), hooked it up to a Dell 3011WFP (which re-acquires the signal much faster than the 3008WFP btw), reset monitors to factory defaults, and installed the latest drivers. To no avail.

Help?!?

I got the similar issue with my new pc.

ZOTAC Z77-ITX WiFi +3770K i7

Monitor Dell 30'' with 2560x1600 and Dell 24'' with 1920x1200

The issue is still present also I removed one ram stick. One time the monitor just went blank but other times

I'm having this exact same issue on a laptop I purchased from iBuyPower with the Nvidia 680m w/ Optimus and the Intel HD 4000. It happens anytime I use any configuration that involves an external display (it has HDMI and VGA out).

They are looking into getting a BIOS update from MSI, but in the meantime, removing all but one memory DIMM solved the issue. This is, of course, incredibly frustrating, since I use most of my expanded RAM for a lot of the work I do.

Hello all,

I created a thread here:

I am having the same issue of screen flickering on my HD4000.

I am using a Gigabyte Z77X-UD3H board with their latest beta BIOS (version F19e) and the issue persists.

Gigabyte technical support is unable to confirm that MRC 1.50 is included in their latest beta BIOS. Is there anything else I can do?

In case anyone is passing through from Google (like I did) with this issue on a Gigabyte Z77X-UD5H (or UD3H), a BIOS update will fix it. You need to use the latest (for me, F16g Beta BIOS). My screen was flickering a few times a minutes, every couple of seconds under load. It was driving me crazy. After the BIOS update, no flicker.
