• Screen Flicker at 60hz
    23 replies, posted
My screen has faint flicker, even at 60hz. I've tried many things but to no avail. It only happens in games. It's not because of V Sync, there are no tears or anything, it's faint lines flickering down the screen, like when you point the video camera at the television, it does those black lines down the screen. It's like that but very very faint, but you can see them. I've tried updating graphics drivers, and nothing happened. There are only 2 types of Hz that I can select, which is 59Hz and 60Hz. So I have no idea on what to do, this is why I have come to you guys for assistance. Any help is much appreciated. Thanks.
Do you have a CRT?
No, it's an Asus LCD 20", running at 1680 x 1050 resolution. It hasn't done this before because I've used it on previous computers.
So, this only happens on the computer you're using it for right now? [editline]24th January 2011[/editline] Do you have pictures or videos of it?

I don't have any photos or video of it no. Just imagine you're video taping a screen and there's black likes streaming down it, it's exactly like that but very very faint, they're not thick black lines it's like blurred. I figured if I photographed it or took a video of it then it wouldn't really show it as they would show up on the photo/video anyway. It's only happened since I got my new computer. It runs a GeForce 460 GTX 1024MB.
Have you been overclocking it?
[QUOTE=NeoTheOne;27630431]Faulty GPU?[/QUOTE] I don't see how it could be faulty because it running. I have no problems in games or anywhere else.
Hmm. Can you try the graphics card in another computer? If the problem stops when the graphics card is in another computer, it could be your PSU, just a guess though
[QUOTE=NeoTheOne;27630461]Have you been overclocking it?[/QUOTE] No I never overclock nor I ever will. [editline]24th January 2011[/editline] [QUOTE=Warship;27630475]Hmm.

[QUOTE=NeoTheOne;27630493]Just because it can render some 3D doesn't mean it's completely fine.[/QUOTE] I've had ZERO problems since I got it. It SEEMS fine. There's be no faults whatsoever.
If it's not a custom build you should probably talk to the manufacturer, if it is try another GPU.
LCD's use tube lights AFAIK. It sounds to me like your backlight is on its way out (like when a tube light in a classroom or office starts to flicker when it begins to die).
I see in the settings of the monitor, in List Of Modes. That it keeps changing back to 59Hz even thought I set it to 60Hz. But on the nVidia control panel, it's set to 60Hz, and on the monitor itself. [editline]24th January 2011[/editline] [QUOTE=Jallen;27630579]LCD's use tube lights AFAIK.

Sounds a bit like a flickering backlight. Though it'd be flickering damn regular.

It's ONLY in games though. Not seen anywhere else.
It's not a faulty GPU. That's 60hz for you. 50hz is almost unbearable. I'm assuming your refresh rate was higher on the other systems you used it on. Try experimenting with the resolutions until you can get something that's 70hz+.
I don't see them and my monitor is only 60hz. Also an Asus LCD. (But slightly bigger with a webcam built in)

Download a temperature monitoring program like SpeedFan or GPU-Z and see what temps you're getting in and out of game (leave it running a bit, especially check temps when you get the flicker thing).
Using VGA? Maybe your cable is bad.

I did that when after about a week when I first got the computer. Just done it now and it's on 38 Degrees, this is while playing a game.
