Does video cards make monitors have better IQ ?

[psyside]

Want to know does the vga makes any diffrence for movies and desktop use?
not talking about games and 3D applications.Sorry for noob question

Lets say you got 285 vs 7600GT

For your standard graphics cards, I don't think there's any difference. However, there are specialist graphics cards made by nVidia and ATI that have drivers specifically for working with and boosting the performance of desktop applications (such as the nVidia Quadro line).

Ok thanks

For VGA outputs the RAMDAC quality makes a big difference. It used to be that outside Matrox cards whatever ATi and nVidia came up with were crappy RAMDACs providing horrible analogue quality. Nowadays the difference isn't so big anymore.

As for digital outputs, you'd be hard pressed to see any difference. If you want the best possible IQ, use a proper hardware calibration tool like the LaCie Blue Eye (Pro).

Ok dudes thanks.

There is absolutely no difference between cards sending a digital (DIV/HDMI) signal to a normal monitor. (no matter if it's $20 onboard S3 or $5000 Nvidia Quadro it will be exactly the same data, the later might support 10bit color when paired with an equally expensive display though..)

As Elledan stated the only thing that can make a difference desktop use is the calibration. (ether with specialized hardware, or simply by changing the settings in the drivers (gamma, contrast etc.))
With movies, most new cards can have hardware to support for getting the compressed video to the output.
So a better card could make a difference in therms of movie quality because more power and available free CPU cycles could translate into more post processing options.. don't know much about it though, maybe someone else knows more about the different cards, player software ect.

For all intents and purposes you probably have, no...there will not be a difference.
