Question about Computers & Internet

A surge may have fried it if you didn't have it on a UPS (Uninterruptible Power Supply).
Here's some tricks I would try. Something here, might help...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

I think it might be the Caps in the power supply. If you can open the unit up, find the power supply. See if there any caps are bulging on the top. If they are they need to be replaced. There maybe as many as 4 to 6 caps you need to replace, If the caps are 16v replace with 25v, If they are 25v replace with 35v. This is because some of these caps in power supplies are under rated. Always use the same mfd's that is on the old cap.Make sure you do not put them in backwards. They do have a + and a - . This is all being said assuming you know a little about electronics and good with a soldering iron. Hopes this is helpful.

This looks like a driver/resolution problem. Which laptop are you using? New laptops shouldn't give you any hassles, but older models don't always have the graphics cards to support all monitor sizes.
Make sure your monitor driver is installed on the laptop and that you have the latest graphics drivers installed for your laptop.
You can download the screen driver here: http://driverzone.com/device.php?id=55741
Then check that the resolution for your monitor is set correctly on your laptop under display properties. The native resolution for the screen is 1280x1024.
Hope this helps,
