Hiii I have a problem... I just bought a vga cable so I can transfer my Windows 10 screen onto my Emerson tv screen. But when I plug it in, video does not come up. I have gone into settings and made sure everything is good, what now? Also, my Computer used to have Windows 7 software, I only got the free 3GB upgrade to Windows 10. It is also a TOSHIBA laptop. Please help me!
