Which scaling method for my LCD?

[BossNoodleKaboodle]

I've got a Dell 1704FPT using DVI from my graphics card as the input. If I'm playing a game at 1024x768 which method of scaling should I use in the Nvidia driver control panel??? The two best options seem to be Monitor Scaling or Display Adapter, which one is preferable?

I usually just use monitor scaling, but that's just for ease of use. For reference I'm using a 2005fpw.
