So i bought a Samsung HDTV monitor LN-S1952W
and i bought a DVI cable and hooked it up to my PNY 7900GS graphics card

and i dont see a difference at all except brighter colors...did i do something wrong? is there a button i have to press? so from my graphics card i connected my DVI wire to the DVI spot on the monitor. MY graphics card says it supports HD

Specs
WIN XP 64bit
AMD 3500+
KN1 Lite motherboard
2gigs RAM
PNY GeForce 7900GS

Thanks

What exactly where you expecting from a 1440x900 Samsung display? most computer monitors have higher resolution then that. My 21 inch pc monitor can go up to 2048x1536.

I'm not exactly sure what you though an HDTV was compared to a computer monitor, but in all honesty its nothing major, except most HDTV's come in much larger sizes then pc monitors.

Are you gaming or watching movies or what? Games run best on a CRT Monitor because you can change the resolution to whatever you want depending on the game and graphical demand.
Movies on the other hand look better on HDTV's because of generally being wide screen and larger picture.
Unless were talking about HD-DVD or BLU-RAY, then, the higher the resolution the better.

How can i get up to 1440x900?

I can only use 1136x684...anything bigger and i cant see the Start Button
