in my apartment, i set my surround sound, pc, and ps3 to a 42" 1080i HDTV.
my resolution is currently set @ 1360x768, but i know it can go higher. how? i don't know...
i have the normal monitor cable plugged into the tv (vga?)
i know one option is to use a dvi cable (

but, the tv doesn't have dvi input. i heard an alternative would be a cable that uses dvi to plug into the video card, and hdmi to plug into the tv. someone i know tried, and resulted in lower resolution, so i'm kinda not considering that.
my real question is can i download a driver or any sort of program to increase or change the resolution? do i have any other options without spending a shitload of $?
