LCD Monitor Ghosting - What's wrong?

I have just updated my brother's PC with my old NVIDIA 5950 Ultra graphics card. The monitor (an 17" LCD Panel) is now experiencing really bad ghosting. I have been using the card right up until a few days ago and I can't figure out what's wrong with it.

I have checked the sharpness settings, refresh rates and resolutions but nothing seems to make a difference :(

There are 2 ports on the card. VGA and DVI - I am currently using a VGA lead, would using the DVI make a difference?

Thanks,

DVI won't make a difference.  Does the monitor suffer ghosting with all machines?  I think it's either the card or the monitor, but you need to check them against working models.

Both the card and monitor are fine - I have used them both together in the past but with a DVI cable with no issues. I just didnt want to spend £10+ on a DVI cable if I could sort the problem manually :)

Like I said I have been using the card fine before now, on my 19" widescreen LCD with a VGA connection. No problems. My bro has been using the monitor with some Dell issued graphics card that can with his PC on VGA with no problems...

I guess it's just the mix of the card, monitor and VGA cables....?

Adjust the refresh rate and resolution.  This may solve the problem.

He solved his own issue....read his last note :P
I've seen this with LCDs on a KVM. Is he using a KVM?

I've also had this problem with some CTX monitors. For some reason they had slight ghosting until I installed the driver disk that came with them. Check the monitor manufacturers website to see if they have a driver for the monitor.

Thank you for all your responses!

It is very interesting to see what you all think and what possible causes there are. Unfortunately the simplest explanation was the right one!

I changed the cable to DVI and the ghosting magically disapeared! It must have been a bad quality VGA cable or a dodgy VGA connection on the card (it is getting on for 3 years old i think!)

Thanks again for all your help guys - i wish i could give you all lots of points!

(Callandor) "The DVI cable may give you more brilliant colors and slightly sharper images, but it will not deal with ghosting"

Ooooooooooo.    I think this is the very first time I've EVER seen Callandor miss.   I'm gonna bask in the moment...  

:-) :-) :-) :-)
I was working on the assumption that the VGA cable was working - I'll bet a new VGA cable would be just as good, if the cable was the problem ;-)    I did suggest "I would try a different VGA cable to see if that can be eliminated."

A 6-ft working VGA cable has a picture quality that is very hard to tell from a working DVI cable, when dealing with monitor-sized displays.
Callandor I knew what you meant :)

But it seems as though simply changing the cable solved the problem. That will teach my bro to buy cheap merchendise.

On a different note I managed to brick my new mobo by damaging one of the "wires" while trying to plug in a new graphics card - what a n00b things to do...I feel so embarassed lol!!

Thanks again guys!
