New Video card installed--now LCD monitor has "white noise" or interference via DVI; analog connection works somewhat

I have a Dell 8200.  Recently the video card burned out and I had the system diagnosed--it was in fact the video card. I then had them install a new video card for me (it is an ATI Radeon 9550).

When I tried to reconnect my Dell 2000 FP LCD via the DVI cable that I'd been using without any problems before the video card was replaced, the display had a lot of white noise or interference (sorry don't know the appropriate term for the problem).  Essentially it looks like a white screen over the display.

I then had the system plugged into a new LCD, which seemed to be OK using my DVI cable.  Then I had them plug my monitor into another system and they said the problem was apparent after a minute or two.

Considering the monitor was absolutely fine before the video card burned out and the monitor cost $1500, I wanted to try everything before giving up on it.  So I bought a VGA (Belkin) cable and a new DVI cable (Monster).  The VGA cable worked fine at VGA 600x800, but was too low-resolution to be workable for me.  Any higher resolution setting resulted in a "box" display that was compressed and doesn't look right.  I then used the new DVI cable and the white "screen" returned.

A friend of mine is a PC repair man and guesses that my LCD is fine.  Can you suggest anything to me considering the monitor worked perfectly before the video card problems?

Reset your monitor to default.

though your friend suggested that the LCD panel is fine..it indeed may not be if my above comment doesn't work.

you LCD panel will have on board monitor controls such as brightness, contracts, degaussing, etc.. it would be prudent for you to read your manual and locate this function. Hopefully, it does exist.

I will look through the manual.  But as far as I can remember, I did nothing to the factory settings other than selecting the DVI input.  Thanks.

but your video card went out on you and that can impact the configuration that was once applied to the old card.

old configuration doesn't mix on current video card.

OR

the old video card that burned out, took out some element of your LCD monitor.

I just checked.  Looks like the monitor came with a CD but no manual.  Are you thinking that analog connection with 600x800 is the best I'll get out of it from now on?

Perhaps running that setup CD would help?

Irwin SantosComputer Integration SpecialistCommented:
Review the CD as it does have the manual in there.  As for the resolution...not sure until you are able to reset.

Check the warranty for your display, most have more than 1 year's warranty and often it is onsite. I'd check that out as an option.

Thanks rindi,

It's a monitor from 2002 though, so I think any warranty is likely up.  I will double-check though.  It was $1500 at the time so I am hoping to get as much use out of it as possible.

How big is that LCD monitor?

chrisyanoAuthor Commented:
It's a 20.1 LCD.  Also, I just tried the cheap S-video cable that came with the new video card.  It worked, but image quality was very poor and blurry--also "black boxed" as it didn't display on the whole screen (black bars on top, bottom, left, and right).

a 19" Wide Viewsonic LCD is $348 at CompUSA :-D

perhaps excercise that warranty as rindi mentioned?

chrisyanoAuthor Commented:
Unfortunately it is a 3-year limited warranty.  I think I'm out of luck either way there.  I know LCDs are much cheaper now but hate to buy something if I don't need to--especially for business equipment.

Anyway, I reviewed the CD and it showed me how to restore the factory settings.  That did allow for some of the resolutions (unfortunately not all) to "fill" more of the screen with the VGA cable.  It has some shadows, but is much better than 800x600.

I will now see if the DVI cable will work, as that would give me a sharper image.  Either way, I can't thank you enough for your help.

LEt's add to this..how about downloading the latest video driver and installating?

in addition, your LCD monitor "may" have drivers.  If so, let's take care of that too.

Ok, tried the original DVI cable and the Monster Cable DVI that I recently bought.  They both still had the same white lines running through the screen, but now the display even flashes on and off when connected by DVI.

I will download the latest drivers for the video card and monitor (if any) and see if installing them does anything for the DVI support.
