I am trying to hook my laptop up to my tv. I am using Windows 8 on my laptop. I bought a vga to rca cable off of amazon. I hooked the cable up to the laptop and to the tv through the component jack on back of tv. I turn it to the cmpt 1 channel on tv. U can see the screen but it shows in the long columns. how do i turn it into the whole screen so i can i can watch netflix and movies off my laptop on my tv? I also went to my display settings on laptop and changed it to project second screen. PLEASE HELP ME...
