ViewSonicMY

I bought a Viewsonic monitor.

(1) Do I need to download & install a driver?

(2) Do I need to register for the warranty online?
The physical shop I bought it from gave 1 year warranty but actually the manufacturer warranty is 3 years. Am I right?
If below 1 year, I can send it back to the shop where I bought it from. If more than 1 year, then I have to send it back to the manufacturer. Am I right?
