Samsung 152T digital

I have bought a Samsung 152T which has both analogue and digital capability.
Im currently using it in analogue, which i must say is quite nice.
However i wanted to use it in digital mode as it apparently gives better frame speed, higher quaslity pic etc.
But how does one install the digital drivers for it - how do u get it going lol?
As when i got it i had to install it via Nview to get analogue working.
Im using a GEfoece 4 TI 4400 with 41.09 nivida drivers
It had a DVI extention to which i plugged the diigital cable in.
It originally said cannot get signal or something like that.
My Nivida card see a plug and play mointor on the DVI connection but when i switch to it - it does the screentest and nothing - screen goes black.
Doesnt like that monitor
If any one here has installed digital on nivida card or a samsung can u please give me some installation tips.
The mannual is worthless and ive instaled the drivers from samsung as well.

I have both cablss plugged in a well , analogue and DVI.
Should I have only one in.
ANy tips appreciated.

Yeah i unplugged it
cant get it to work
was wondering if anyone esle had similar problems
or if they could tell me how they installe dthere digital screens ie samsung models

Yeah im hoping for a sligt increase in the quality
the screens i gte are nice and clear BTW i like it
although not perfect its good value for money untill much further down the track
the games I play are Neverwinter Nights, Combat mission 1 and 2, and Operation Flashpoint - ive good good quality screens so far cant complain and my eyes dont hurt no more.
