There are a lot of computer experts on this system, so I was hoping someone would know the answer to this.
On my daughter's old PC, the LCD display has a very pronounced "horizontal shadow" of sorts. That is, if I open a small window on the Windows desktop, there are horizontal streaks paralleling that window, running the full width of the display. The streaks are still the general background color of the Windows desktop, but in different shades. If I move the window around, the smudges go up and down with it.
In a window with a lot of text, you see darker smudges at the same vertical coordinates as the text, again going across the screen.
At first I thought it was the monitor, a 2.5 year old Dell 1703FP LCD, hooked up via analog RGB cable to the PC's old NVidia GeForce 256 (AGP) display card.
But I plugged my notebook into the monitor and the display was fine. So it's not the LCD.
I looked all over the display settings, trying to find something, but could not. There's all sorts of settings for the NVidia stuff but nothing obvious. I even changed a few, but no luck. The driver seems fairly well-updated, circa 2003. Changing a few settings, rebooting, etc. don't seem to have helped. I've switched resolutions and sync rates, no help.
The strange thing is that this combo has worked fine for nearly two years now. It just started suddenly. Windows Update runs against it automatically. The PC does take a lot of abuse from my 3.5 year old daughter, and there are a lot of games running on it that switch the display mode.
Could the display card be going bad? Should I just buy a cheap AGP card to replace it
Thanks in advance. |

Before trashing my daughter's 15" LCD from Dell after experiencing the same symptoms, I tried a few things...
You already tried the monitor on another machine so you've already ruled that out.
1. Try a different VGA cable. Yours may have gone bad or has a bent pin.
2. Upgrade your vide cards drivers and choose their default settings.
3. Update your DirectX drivers.
4. Start Windows in VGA mode (F8 at boot and choose VGA) and see if you still see the lines. If so, I would replace the card. |
