You need to learn a bit more about hardware--I'm just guessing here.
It may have detected the correct brand of monitor, but not necessarily the correct model.
Do a search on http://www.google.com
for the manufacture of your monitor/display, go to support and look for the specifications for it--like the frequency ranges for it. Print that page out. It may be that you have to check your configuration file to see if the correct settings were applied from the database.
If those things are correct--well then, you may have a problem with the video adapter card. Many of the newer cards have to have custom drivers installed to work properly.
Boot your windows installation and look in the hardware manager for the video adapter. Make note of the make model and version of the adapter.
Then, do a search on http://www.google.com/linux
using that information.
Chances are the adapter is supported, but you may have to download and install a driver for it.
When you have possible hardware-related problems, do a listing of the hardware (motherboard, video adapter, sound card etc.). This will enable those who may have had the same problem and over came it to answer you.
Don't expect us to be psychic.
