Is the computer a newly assembled one? Post all the specs for the computer including power supply and graphics card.

Disconnect the monitor from the VGA/DVI port but connect it to power.
Try to turn it on. You should be able to get to it's on-screen display settings screen and/or get an onscreen message about Signal out of range.
If the thing is still showing the same "Off after 2 seconds" behavior then the problem is in the monitor and probably in it's powersupply.

Unless it is under warranty I'd suggest replacement.

Have the same problem regularly with an Acer notebook and a Hyundai LCD.

Changing resolutions or switching from Clone to Extend will always show the desktop for 2 seconds, then it goes black again. Even the OSD won't come up.

Solution here: In the ATI Catalyst Control Center, go to the "Desktops & Displays" section. Select the second display and deactivate it (Right-click on Icon, then Deactivate).
After that, set it to the desired mode (e.g. Extend). (Again, Right click, then "Extend").

This works for me every time.
