My screen has been flickering for a couple weeks now and I'm wondering if I'll have to buy a new monitor. It's been less than a year since I bought it. I think the cause might have been because I used an animated wallpaper program as my screen saver / default background but I'm not positive on that. I've tried a couple solutions but the only thing that has worked is changing the refresh rate. After doing that fix, every couple days the screen flickering would come back, usually after I turned on the computer / monitor again after waking up. So I would change the refresh rate and that usually fixed it but not this time. Now not even that works. Any suggestions?
