Check device manager for driver.

Please go to start>search>type device manager.
Are there any "unknown devices" with yellow triangles on them?
Is you driver there , listed, and working?

If your driver is missing, or there is a yellow triangle on it, you will need to update it.

If you were using an computer monitor previously that was using a higher non - Vga resolution, Ex - 1920 x 1080 then you may have to go into display properties and switch to a lower Vga supported resolution, Ex - 1024 x 768. It is also a good idea to check in the Bios ( if applicable ) if video output is set to on board or PCI-E.

Also if your TV and computer support it a DVI or HDMI connection will yield much better picture quality and higher resolutions.
