How to find Monitor specs

In order to insert a modeline for my EeePC screen in the /etc/X11/xorg.conf, I needed to drag up quite a lot of relevant information.
By typing
xvidtune -show
you get much of it like the following

"1024x600" 50.40 1024 1048 1184 1344 600 600 619 625 -hsync -vsync

This thread has a lot of useful pointers as to what these numbers mean as has this Wikipedia article.
Now you need to generate the modeline. You can do this with this Modeline Generator or you can just use the gtf tool as described here. To use it just type gtf followed by your resolution and the refresh rate into a terminal as shown
$ gtf 1024 600 60

# 1024x600 @ 60.00 Hz (GTF) hsync: 37.32 kHz; pclk: 48.96 MHz
Modeline "1024x600_60.00" 48.96 1024 1064 1168 1312 600 601 604 622 -HSync +Vsync
