Default Ghosting on screen

I have just noticed that the Mouse pointer and all Large Menu text against a white background is showing slight multiple Ghost images - there is one barely noticeable image alongside the Pointer/Text and then a few more which are a bit faint. My question is this problem likely to increase or will it stay at same level ? I cannot capture this image as the ghost images are not that prominent.... at least for now. This is only noticeable when I have the Mouse Pointer or Large text on a white background.

I suspect it is a Display Card problem - after all I am using a CHEAP BIG 7300GS card The Monitor is a Samsung LCD 740N.

I have tried moving the Monitor wires around with no difference. Also cleaned ther display card. The MoBo is A8N-E and the only other card in computer is an Audigy 2. This AMD setup is only one week old.

Is this slight Ghosting normal ?

EDIT: This does look like a faint version of Mouse Pointer Trails but it is not as prominent as the Trails and it shows even when the Mouse is not in motion. And NO I do not have Mouse Pointer Trails switched on

What I see is not motion ghosting but ghosting like what you see on TV's when you have an antenna out of alignment with a signal.

I already have Clear Type Tuning running.

Here is a picture that shows what my problem is - the Ghosting problem shown in the picture is more than what I see on my screen - what I see is quite faint in comparison to the picture... and I get multiple faint images. Irritating !!!

Samsung 740N has only VGA.... sadly I did not notice this problem with my last P4 setup which I had till 10 days back - only now I noticed this on my new AMD setup when I ran a white page in a Picture editor - it was noticeable alongside the Mouse Pointer.

I have never seen this type of problem in any of my setups.... I think it is the BIG display card's doing. I will try borrow another card and see if the problem goes away.

Eazy... Try playing around with few monitor features... I am sure it is more related to the fine/sharp adjustments of the monitor then anything else...

Also you can chk the PC with a CRT and if you notice the same thing then most probably its the card/driver then anything else... But i am quite sure it is a tuing problem...

Now why did I not think about trying the CRT lying in my Attic OK will get it down and confirm if it the GFX card or the Monitor. THANKS !!! My bet is on the problem being with the BIG CRAPPY card

OK I think I found the reason for the ghosting... It is a BIG problem.... YUP the problem seems to be originating from the BIG card.

This card has a ribbon cable between the PCB and the VGA connector and I think this cable picks up EMI which shows up in these ghost images. When I move the cable around the ghost images change patterns - I have twisted it a bit and this reduced the ghosting to make it barely visible - I can live with what is now generated on screen.
