Do they use the same VGA cable as a CRT?
Probably.
Also, will I need to download a driver?
No.
There are also a number of them available without AC adaptors.
Most now-a-days use a standard power cord, no AC power block needed.
Watch out for dead spots on the screen.
Got a freebie a couple weeks ago. Nice and big. Buuuuuuut. But there is no backlight control -- it's on full bright all the time.
Like I said, the opening bid is VERY low.
Opening bid hardly matters.
