Maybe you have your refresh rate settings too low.
try 75 -80 hertz.

If it's only recent and you haven't changed any settings or anything that would alter something to do with the graphics, check the cord in the back of the monitor. More often than not it's the problem...

Check the Device Manager and see if anything has an exclamation icon.

If the GPU has it, try uninstalling and reinstalling the drivers.

Found your problem. Why the fuck would you use a VGA cable?

Get them from the AMD/ATI website. And is it overclocked, either by you or the manufacturer? This may also occur (in some rare cases) due to poor cooling. Generaly its a driver issue. Are you seeing artifacts (like odd colors and fucked up pixels), that would indicate a cooling issue or clock speed setting is too high, find out what the clock speeds are supposed to be and see if yours are higher from manufacturer overclocking. If all else fails, return it and say the card is bad, get a new one of the exact same type and try that, if it still flickers try your friend's monitor. and get a fucking DVI or HDMI cable for god's sake! And don't be a stupid fuck and buy them from Wal-Mart for $40.00 When you can pick them up at any computer specialty store for $15.00 for a really nice one. And I must say, I have a bachelors in nuclear engineering, and in electrical engineering and I will tell you that the "oxygen" or "air" content of the copper in the wires being extremely low DOESN'T MATTER for a monitor cable that is going to be carrying so low of a current that you WON'T see any adverse effects anyways. Damn those marketing ploys that prey on ignorance piss me off.

$15 is too much for an HDMI cable even. If you're paying more than $4-5 you're overpaying. Oxygen content of the copper only matters as far as oxidation is concerned, and that isn't much of an issue.

Well, I haven't bought an HDMI cable in quite some time, so my pricing is a bit out of date I guess. Well, what they are trying to say is that the lower oxygen or air in the cable will provide a better signal. Well in extreme cases of inconcievably low quality control in the manufacturing of the conductors it would provide enough resistance over the length of the cable with the minuscule amount of current running through it to lower the voltage enough such that it causes significant enough signal degradation to have a noticeable loss of picture/sound quality. But the information on the packaging of some so-called "ultra high quality" cables seems intended to lead the reader to believe that this significant signal loss is possible with the TRACE amount of oxygen/air/random impurities that are in cables made by "other" manufacturers.

For instance 216.167.207.171/productdisplay.asp?pin=3831

Verses 207.171.166.252/HDMI-meter-foot-cable-1080P/dp/B0002L5R78

I can't post URL's so I used the IP instead of the domain for monster cable dot com (the first one), and amazon dot com (the second one). Those should work in your browser if you just copy and paste to your address bar.

With those two cables the quality difference should not be noticeable, since there is an industry standard for manufacturing these cables so they conform to the HDMI quality standards.

There is no reason you would want one of those super wamo-dyne ultra mega high purity platinum coated diamond based super conductor, coated in a Dupont aromatic polyamide with an operating temperature range over 220 degrees centigrade and with superb high voltage breakdown (Nomex) made with manufacturing techniques that won't be dreamed of for at least 80 more years ALL for the Bargain price of $5000.00/in. just because they tell you that your Xbox 360 or computer or home theater won't even be able to do 480p without it.

Oh yeah and unfortunately they only sell those in 6 inch segments, so you have to buy the X-TREME efficiency male to male coupling made with Rhodium type 1 super conductor with a laser-cooling system developed at MIT to keep the Rhodium around 0.000325 Degrees Kelvin in a designer iodized platinum enclosure with solid Inductively Coupled Plasma Spectrometry tested 24kt gold contacts to extend the cable. Lucky for you wal-mart has those on sale for a mere $5mil each.

unless you're using a 9 mile long cable or something, differences between "quality" cables and "shit" will be imperceivable, if they even exist at all.

cheap ass cables are fine. i bought a couple 1 cent hdmi cables on monoprice a while back, they work fine.

It's clocked by manufactor.
What can I do if it's a driver issue? I've reinstalled the drivers.
I kind of see the gray lines that you see when you have your cell phone near the monitor. Like that kinds of flicker.
But I don't see any artifacts like I did on my laptop.

Also I have to pay really much. I live in a overpriced country. And If I buy it from the net I have to pay alot of additional taxes so that's just even more expensive.

Luckily for me I have two monitors and two gpus Wink

HOLY FUCKIng SHIT. I DONT WANNA SEND BACK THAT 24" SCREEN.. ARGGH. Do I have to pay to send it back?? like €50....

I've heard about the 9.7 drivers causing flickering, and they dropped TF2 from a constant 100+ FPS down to 20-30 for me. I downgraded to 9.6, but supposedly 9.8 have been leaked and fix the issue.

I also have a 4890, by the way.

HDMI killed all the flicker.
