I was wondering if anyone else has run into this. Out of nowhere, my monitor started doing it today, and I was wondering whether it had anything to do with the graphics card, or the monitor going bad. I'm hoping it's the gfx card because it only cost me $40. The monitor cost me over $400. A horizontal flicker/tear at any vertical point in the screen, going from one side all the way to the other, perfectly even, very quick, and about the thickness of a finger (or thinner). It distorts greatly within that tear area, and slightly blurs the picture nearby, very briefly. It doesn't have any positioning pattern, and seems to occur only when it's in the mood. I am now using my old graphics card, and so far it hasn't happened anymore. However, it was reducing frequency before I exchanged graphics cards, so perhaps I just have to wait longer to see it. When it happened, it was within the first 5 or so minutes of startup after being powered down for the night. It repeated itself frequently over the course of a few minutes, always in a different place, and very consistent in appearance (always distorted the same way, blurred slightly nearby for short durations) If anyone else has experienced this, please let me know what you think it is, and any way there might be to remedy it without costing lots of money Thanks, form I completely forgot a few important details: The monitor is a CRT Sony CPD-G420S, and the graphics cards are ati rage 128 pci and radeon 7000 pci. The radeon was the one I was having the issues on. So far, I've been running the old card for about 20 minutes without any issues.
