First of all if you've checked that the monitor is still plugged to electricity and won't work, I recommend you to take it to a specialist, so it will give you a solution.

Make sure the power cable and video cable are securely connected.  If that doesn't solve the problem, hook your monitor up to a friend's computer.  Same problem?  Then you have a bad display.  Works ok on a different computer?  Probably a bad video card in your computer.\n\nI'd also suggest using different power and video cables if you have access to others.  You might find that you just have a bad cable.\n\nGood luck

First look at the adaptor and get the output rating of the adaptor. It will also show a pictogram of the adaptor plug this shows what part is negative and positive at the laptop end). Look for a new adaptor that has the same rating (or extremely close) and the same pictogram of the plug.\n\nThe ones for the laptop may be quite expensive.\n\nAlso get the battery looked at, it may be faulty.

Most likely, it is either a bad connection, faulty cable, graphics card is going bad, or monitor is going bad.  I would start with the connections; make sure they are clean and tight.  Try swapping out cables if possible.  If both these fail, then you are going to need to test a second monitor and then a second graphics card which will get a bit tricky and will require a second computer or help from a neighbor.

It could actually be your computer screen. I know that my old laptop had a malfunctioning screen. Try contacting the manufacturer to see if infact it is a monitor problem and not a software problem.

try restarting the computer and if that doesn't work check your display settings

Unfortunately you can't.\nThe video-outs you have are the only ones you can use, so you are limited to the laptop monitor and one external is you have a VGA or S-video output.

Check the cabling between the monitor and the PC. It may be a bad connection.

There should be a combination of keys you can push to get it to switch displays.  For Compaqs, I think it's Fn+F4.  For Dells, it's Fn+F8.\n\nSee if any of the keys on your keyboard has a picture of a monitor or the words "CRT/LCD," in a different color.  That, combined with your Fn key, usually tells the display to output somewhere else.  Good luck.  =)

the projector will need to be pluged in and turned on at the time of the change... possably when the laptop is booted as well.\n\nit could also be disagreeing with the resolution of the projector. there should be an option to not extend your monitor but to clone it... i'd see if that gets you any further.

Yes.  DVI to DVI is all you need for the connection.  You want to make sure the video card in your laptop can hadle Dual monitors if that is your intention.  Sometimes Dual monitors plus not enough juice in the video card equals a crashing CPU.

If your laptop has a yellow video port, with an RCA jack connection, just use a common video cable to hook the laptop's yellow plug with the yellow plug on the TV.  \nIf your laptop has only the external monitor port, you probably won't be able to connect the two without an adapter.

Laptops usually have an output for connecting a monitor. When you use that output it may disable the laptop screen. If that is what happened there is probably a key or key combination that could be used to enable your screen again. The key or key combination depends on the laptop so you should check your manual.

if using windows go to your display or monitor properties screen, and look for something that says refresh rate and turn it up untill the lines go away, if that doesnt work your monitor might be going bad
