This could be an issue with the display settings either not being set to mirror or extend the desktop, or the resolution for the TV in the computer display settings being set too high or too low.

 

Right click on the desktop and click on Personalize and in the new window click on Display.

 

With the TV connected to the computer, do two screens show up in the display settings window?

One Happy CustomerNew York

I am very happy with my very fast response. Eric is very knowledgeable in the subject area. Thank you!

RPAustin, TX

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
