Hi all,

Recently won this card on eBay for a pittance, it's a great card but for some reason the output is smeared on dark areas. Any black lines smear across quite heavily. Physically the card appears to be in excellent shape and there's no missing components.

I don't have actual pictures of the card (bad lighting at the moment) but it basically looks as these pics:

I've attached an image of the output I see (ignore the red line, that's just the crappy LCD I'm using).

Where should I be looking on here?

I habe exactly the same Problem with an Elsa Erazor X2 card although it is in excellent shape.

Ah bugger. I wonder what the issue is! I just tried removing the filtering caps (C9, C10, C11) but it didn't make any difference.

Have you tried readjusting the VGA cable? That's pretty bad for it to be the cable but my ghosting seems to get better or worse depending on adjusting the cable.

I can confirm it's not the cable as switching to another card resolves the issue. Someone else has posted the same issue, it appears to be a problem either with the RAMDAC or the nearby circuitry I think.

I have GeForce 256 with the same issue, so I'm starting to think that it's rare RAMDAC hardware failure on early Nvidia cards.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

Ahh poop, it does look that way.

I wonder if the signal can be rectified in some way; I guess not though!
