I recently jumped on the Widescreen LCD train and picked up an lg 20inch widescreen lcd.
Now I hooked it up installed drivers all that jazz and then on my desktop (which is all black) I noticed white, brighter then the black in the middle patches on all sides of my screen going towards the middle a good 1/8 of monitor.
So thinking I got a defective new monitor I plugged in the old one and sure enough the patches were still there. So now im thinking how have I not noticed this for all this time...
I'm pretty sure its not a video card driver issue because I can see bright patches before windows loads up in the early screens when you turn it on, but after this message im going to install the newest drivers for my video card.
Can anyone help me deal with this problem? The video card (and computer itself) is only about 4 months old. Faulty video card?
You are experiencing backlight bleeding which affects all LCD monitors even the more expensive ones. However, it seems backlight bleeding is more common on less expensive monitors which uses something called TN panel technology found in the vast majority of any size monitor costing less than $550.
Try lowering brightness and contrast which should help diminish the "patchiness", but you will likely still see some. If you can, post a large picture of your monitor with the black ground in normal lighting conditions. It could be that your monitor has an excessive amount backlight bleeding.
its not just the new one... its the old one too... i asked my buddy to come over and look and he agreed with me that it was happening with both the new and the old in the same spot. i installed the newest drivers and that didn't fix anything... tomorrow im gonna swap out the 4850 for my old 1650 and see if it stills persists. if thst is the case then i will try using a straight up dvi cable because right now i am using a dvi to vga adapter, which might be the problem but i tried. 2 different adapters and both still that the spots... sorry for wall of text im writing this on an ipod touch now
