First of all thanks to you all for your time and help. I really appreciate it.
The other piece of the puzzle is what graphics hardware do you have and what driver are you using? I have nVidia hardware and static image quality is the same between the free nv driver and the non-free nVidia driver (but nVidia driver gives hardware decoding for watching movies).
I've BFG's GeForce(nvidia) 7800GS OC 256MB AGP card. when i use debian etch's "nv" driver with [EMAIL PROTECTED](native for my monitor) everything on Gnome and Gnome Login Window is blurry. So i had to install nvidia's driver(from nvidia's website) and then Gnome visual improves(not 100%) but Gnome Loggin Window is worse as before.
Under the "Monitor" section of the file /etc/X11/xorg.conf, add the following line. VertRefresh 60
Okay i did that rebooted and still vertical refresh rate wont go beyond 57Hz. Is there any other way to increase the v refresh rate? I also tried to increase the v sync rate through nvidia's "nvidia-settings" tool but couldn't as that particular option was disabled.
