When I connect my tv via HDMI it will show the computer screen, but I can't get it to 'extend'. When I go to Screen Resolution and the drop down menu for the display it only shows the computer monitor... not the tv. Help me pls.

Yes, I did. That was one of the first things I did. My computer does not detect my tv screen. Now, it won't even show the screen when I have it connected.

What video card do you have, and what type of connections are used for each monitor? If you don't have a video card, dual monitors may not work

Hello... Right click your desktop-screen resolution-multiple displays-extend these displays. Use this Area for your master control of OS display/monitor settings...
1) do you see your New Monitor here?
2) where is your New monitor plugged into?
3) what type of cable are you using?
4) did you set the New monitor for the cable input?
