color bleeding, maybe a a horizontal sync issue? does sync even exist in an LCD display?
this is my first PC, so please bare with me. Using a Princeton Graphics 17 inch LCD display, I am getting a problem that doesn't happen when plugged into my other computer. I found Dell's knowledge base page about a similar sounding problem and tried all the things they reecommend, including safe mode and even removing the video card and putting it back in. allow me to explain:
lets assume the windows desktop is set to the old-school solid blue. open up a white window, ie. windows explorer or "my computer". to the right and left of the white window, the desktop's blue is now lighter. this horizontal color bleed exactly correlates with how bright the overlayed window is, so for example there is the most bleed where the windows explorer window has a white background, but there is also bleed where the window's manu bar is (actually making the blue background darker since the menubar is a darker blue). this problem exists to some degree at all points on the screen based on what is to the right or left of the point you look at, no matter what windows are open. as far as I can assertain, it seems like something is wrong with the refresh rate or sync, but only in the horizontal direction. is this even possible? does sync even exist on an LCD display? I have played with every setting I can find, in both XP and the computer's BIOS, and nothing fixes this problem. furthermore, as I said above, the monitor looks great when plugged into my other computer. any help is appreciated.
graphics card is an nVidia GeForce (I guess the original one cause no number is listed after that name), with 64mb video memory, in a 2x AGP slot. resolution is currently set at 60hz. when I switch the resolution to 75hz, which is what I use on my other computer, the screen looks different than it should be, the way it looks when you have it display in 800x600 or 1024x768, instead of its native 1280x1024. the horizontal bleed problem still exists at 75hz, though, so I've left it at 60hz. one problem at a time, ya know?
