-- Posted by JC at 1:05 am on Sep. 3, 2008 I got a tv the other day and it has a VGA port to plug in a computer. So i've done that, and at the moment i've got it running on both screens (computer and tv). How do i make the tv as the default (and only) monitor? The "use this device as primary monitor" option is disabled... -- Posted by Chevy Jackson at 1:08 am on Sep. 3, 2008 Are you using vista? If you are, then you have to go into some monitor options in the control panel (it's not the normal display options) and there's an option to switch between external only, both screens, or monitor only. Sorry I can't be more descriptive, but I'm not on my vista machine right now. The best I can describe it is an option screen that has things like wireless settings, brightness, battery options, and sound all in one window. -- Posted by JC at 1:10 am on Sep. 3, 2008 i'm using XP, and i've done it before, last time all i had to do was close the laptop and the other monitor would take over as default, but this time when i do it, the other monitor just goes blue and says "no signal" -- Posted by TheBigFish1991 at 1:10 am on Sep. 3, 2008 at the moment i am doing sorta the same thing... i have a screen plugged in because my laptops keyboard is stuffed and yer so i leave it under the desk with a cooler pad..... on ur keyboard u should have a key that looks like a screen...
