The sound driver is the one labeled Realtek High Definition Audio Driver.
This is a must-have driver. Works better than anything standard you'll get with your audio equipment.
What size/resolution is your current monitor? I don't think PC monitors cost more... you can get a 1920x1080 monitor pretty cheap these days, but a 1080p TV will cost you a few hundred dollars at least.
I think it's a 23", 16:9, 1920x1080.
I want to get a 40-something/50-something" wide-widescreen, 16:10, and want to be able to run things at double my current resolution. Can a TV do this?
PC screens are faster generally too.
What does this mean for gaming?
It is more convenient for me to have a TV screen because I am often doing multiple things and having to switch inputs, and it means i have to move less.
The main reason I want a huge TV screen, too.
