Monitor problems - DGM L-2231WD

post #1 of 3
Thread Starter 
I have been using this monitor for a while now and occasionally i started noticing strange distortion on the screen, similar to this;



but with a lot smaller lines. I didn't think much of it until the other day it got progressively worse and now fills the screen making playing games and generally using the pc incredibly annoying. I brought the PC to the place i bought it from to get a replacement but the guy who sold it me said to just use a different VGA cable just to test. So i plugged his DVI-I cable into my monitor and it was fine, and didn't distort at all. I then plugged my VGA cable in (without splitter, we just used other output on his graphics card) and it was all fuzzy and distorted like before. Not only that but it effected his screen as well so that you had to move the mouse towards the edge of the screen to move the "view" around because the whole desktop wasn't visible. We then tried one Phil (guy who was helping me) gave us and it didn't fuzz at all, despite still having to move the "view" around. We brought the monitor home, and as soon as i got it home and plugged it in i couldn't see anything on screen, so i restarted the pc and the screen was lower resolution and it wasnt just fuzzing, the whole screen looked like it was being stretched, then occasionally the screen would go back to normal. We rebooted and it stopped doing it for a while, but i then checked my catalyst control center monitor properties and for all the categories it said "Not Supported" which is odd because all i had changed was the cable. I then plugged my pc into an old CRT monitor with a different cable (the CRT's cable is attached to it, i couldn't remove it) and it didn't fuzz at all and catalyst correctly reported the monitor properties, and it didn't say "Not supported" for all of them. So i plugged it back into my LCD monitor, and again it said "Not Supported". I also couldn't get the resolution above 1600x1200 when the max is 1680x1050 which i had used before. I'm a bit unsure as to whether it's the monitor or it's the cable. I do remember bending the cable Phil gave us when putting it in the box so that may have messed it up. I am going to try plugging my pc into another LCD monitor i have with the messed up cable to see whether it makes that monitor distort as well, but can anyone tell me whether the cable can actually cause these problems? or is it definately the monitor?

P.S. sorry for long post

I would guess you should try re-installing the drivers for the monitor. Lots of monitors have their own drivers or will perform better with their own, custom drivers.

If you know there aren't drivers for yk.our monitor then delete the stock drivers (for plug & play) & restart. Windows should automatically re-install a fresh set of drivers. Maybe your drivers got corrupted so that could do the trick.

OK, i have tried the monitor in another pc with his cable and it still has distortion, so it can't be drivers that's causing the problem. I am just gonna get a replacement for the monitor, in the meantime i'm gonna have to use my trusty 1280x1024 CRT monitor which, needless to say has no distortion whatsoever.
