shadows on Samsung SyncMaster 753dfx

[Hugo Vanwoerkom <hvw59601@care2.com>]

Hi Debian!

I thought I was smart and since I was satisfied with my Samsung 
SyncMaster 750s I bought a flatscreen 753dfx.

Terrible decision.

The 753dfx has shadows.

It is the monitor because if I swap the videocards the shadows follow 
this monitor.

Everything shown is duplicated in shadowformat, several times.

Anybody have a pointer on how to minimize it?

Thanks.
