How Can I Use Two Monitors At The Same Time?

I have the following component, and equipment I would like to connect with each other:

ATI Sapphire Radeon 9550 256MB 128Bit Video Card

Samsung Sync Master 2253LW 21" DVI/VGA LCD Monitor

LG 37LG30 37" 720p HDTV VGA LCD Tv


I currently have my Samsung pc monitor connected to my video card using a dvi cord. & I'd like to be able to use my large HDTV as a secondary monitor using a vga cord. My video card has both a dvi, and vga output. So I'd like to know how to set these screens up to work with each other displaying the same thing at the same time. I want to do this so I can watch videos on my large HDTV without having to shutdown my pc, disconnect my current dvi Samsung monitor, and attach my tv's vga cord on my video card. It's such a repetitive task to have to do that. Not only that but I'm afraid that the constant plugging and unplugging of these cords will damage the video card outputs.

I want to setup the screens as follows:

Samsung Sync Master 2253LW 21" DVI/VGA LCD Monitor (Primary Monitor #1)

LG 37LG30 37" 720p HDTV VGA LCD Tv (Secondary Monitor #2)


I'd also like to know how I can disable the usage of two screens within my pc when I just want to use my primary display and not use a secondary display. Or for instance when I decide not to have two screens physically connected to my pc at all and go back to the way it is now.

What type of input does your tv have? If HDMI you could get a VGA to HDMI converter but not sure if they exist but i do know VGA to DVI exists and then you could get a DVI to HDMI cable.

 

Oops i don't think VGA to HDMI exists. However you could disconnect your monitors DVI and switch it to VGA if you monitor takes VGA and then buy a DVI to HDMI cable and connect that to your tv.

 

From your description leave the HDMI cable hooked up to the PC and monitor and run a VGA line from the VGA outlet on your PC to the VGA input on your TV. If you want the same picture on both it should be good to go, if it doesn't work right click on an empty area on the desktop and choose properties, choose the Advanced tab and configure from there. If you PC monitor has VGA and HDMI, use the HDMI for the TV and the VGA for the PC, better use of digital signal on the big screen. Sounds like you have DVI on the monitor, one of the two (DVI/HDMI) doesn't carry a sound signal, I just don't recall which. Think it is HDMI.
