Are you using any kind of adapter in the cable?

Are you connecting VGA, DVI, HDMI?

Dumb question but are you connecting to the same VGA port as you were using with your old monitor?

Try the original monitor again. Could be a bad cable.

"....screen goes black"

If you are always getting video while booting with the LCD monitor connected, but after Windows is supposed to load you get NO video, that's easy to fix.

For 2000 or XP...
See response 9 here:
http://www.computing.net/answers/ha...

starting at....
Boot into Enable VGA mode.

Note - that's missing this...

Remove any bootable CDs or DVDs you have in drives.
Press F8 repeatedly while booting, don't hold down the key, starting very early in the boot.
When the Windows boot choices menu appears, choose Enable VGA mode.

Are you using the same cable and video port for both monitors?

The old monitor cable is wired direct inside.

Then you need to test the new monitor and cable on a different computer to verify they are both good.

What type of port are you connecting to? VGA, DVI or HMDI?

Click on the llink below and scroll down to photos of each connector.

You also need to post the model of your computer and if you have an add in video card, the model of that.

People often tell us they have no video when they actually DO have video while booting BEFORE Windows is supposed to load.
If you DO have video before Windows is supposed to load, see response 6 !
.....

If you have no video at all from the LCD monitor, assuming nothing else is wrong.....

If the LCD monitor works with another computer, and if your CRT monitor has a DVI video connection ....

If you have a desktop computer with onboard video - video built into the mboard - and if you are using a DVI (male) to VGA (female) simple gender adapter to connect your VGA LCD monitor to a DVI port for the onboard video, some more recent mboards have onboard video that cannot support you using such a gender adapter - you cannot get VGA output from the DVI port because it does not support DVI-I use (both digital and analog video).

We can confirm whether that is your case if you provide.....

- the make and model of the mboard if you have a generic system
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.

- the make and model of the computer if you have a brand name system.

The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.

If it's a Dell computer...
Go here for how to find the Service tag "number":
http://support.dell.com/support/top...

Tell us what it is.

If it's a HP or Compaq computer.....
Go here:
http://partsurfer.hp.com/search.aspx
Scroll down a bit.
Look for the similar label on the outside of your computer.
Quote the specific model number - that's at the end of the first line.
Quote the Product number - that's on the third line.

If it's a Lenovo computer
Find your specific Product number and tell us what it is:

"Already connect to my laptop which is Gateway modelM-7315u the monitor came up a short time. Using vga cable the same one that i bought to connect to my desk top."

That confirms that there is nothing wrong with the external LCD monitor or the video cable you're using for it.

You need to provide the make and model of the mboard or the brand name computer it does not produce video with - see the last part of response 11.
