VGA no signal on LCD monitor attached to laptop

displayexternal displaylaptoplcdvga

I bought a new Asus vh242h LCD monitor for use with my lenevo T60 laptop running XP professional. Display info under control panel says "Intel(R) 945GM Express Chipset Family". I am connecting via VGA.

When I connect the monitor I get "VGA no signal" and the monitor screen stays blank.

I have selected the monitor as the display device on the laptop. The information on the monitor displays the correct screen resolution from the laptop, so the monitor is communicating in some way with the laptop.

I've successfully tried the monitor with my Dell inspirion 1525 running Windows Vista. I've change the VGA cable to one I know works. Tried different resolutions.

I cannot find and specific drivers on the internet for this monitor, so I assume it should work with Plug and Play.

Does anyone know what the problem could be?

Most laptops have a function-key combination you must press to activate the external monitor. On ThinkPads it's FN-F7. I don't know what it is on the Asus--look for a keycap that has a little picture of a monitor, and press the Fn key and that.

You can also try powering off the laptop, plugging in the monitor, and powering on. On some laptops a monitor is only detected if it's present at power-on.
