Did you see anything at all when you boot up the computer?  Things like BIOS settings/ Chipset.... that would generally show up on the monitor.  Maybe the resolution setting is much more than what your monitor can handle.  Reboot and log in Safe Mode and lower the resolution.

We had what we thought was a dead monitor at the library I work at.  Turned out that the vga connector into the CPU was loose.  The tech jiggled the connection and the monitor came back on.  Hope I explained it correctly.

this happened to me...you donot need a new monitor simply run the computer in safe mode by pressing F8 at the startup screen (manufactor's logo) and choosing safe mode...then do a system restore to before you changed the resolution by going to start>all programs>accesories>system tools>system restore

Do you have the drivers for your monitor installed to the computer? Mine did the same thing before i had them installed and also would not let me change the resolution.Try that

The monitor is working... this is the standby state, sounds like your "gateway" is having video problems try downloading a new driver for your graphics/video http://support.gateway.com/support/drivers/dlcenter.asp

it shouldn't do that, try to unplug the monitor from the pc and then plug it back

It might be a single resolution burned out of the screen. I hope I'm wrong. The screens are so cheap now, I doubt it's worth fixing..Good Luck.

Check that the monitor cable is correctly connected.\nIf it is, then get a new monitor from some place with a good returns policy - just in case the problem is with your graphics card!!

Sounds as if your video card has no output.  Check to make sure your monitor cable is not loose.  If it isn't, your video card could have died.

Most likely it's getting Old...You can try to correct this with you screen settings via you Video card...First try you gamma setting, contrast, brightness...but as cheap as Monitors are now, you better off getting a New LCD flat screen monitor anyways...

Brand names really don't make much difference.  Sounds like the computer needs a new video card.  Perhaps the light setting dial under the monitor may have been moved to dark also.  Hoope this heps

If your lcd monitor boot up with the pc and able to show the desktop, then 99% you are okay, 10 sec of black screen is normal unless it happen just recently. \nFor a pc to boot up to the desktop, the bios recognize the hardware then the loading of platform, there is not much to show unless you change the bios settings on some motherboard, so it should be generally dark.\nConnection between pc and monitor shouldnt be a issue as normally you won't touch that, if it's connected, it should work, otherwise it won't be 10 sec delay only.

You should be able to boot up using a default mode on your display then upgrade.\n\nAlso, the display should be there, look under control panel->display->settings.

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

It sounds like your video card got jarred loose, or is bad.  Try reseating it, if that doesn't work, you may need a new one.\n\nBy the way, the computer itself comes on, right?
