Re: will come on-then say no signal
If you mean the monitor is fine during the Windows booting process and then just as your about to go into Windows goes black then do this...
Start the computer
When the bios screen goes start pressing F8
A Windows Startup screen will appear
If you see the Windows Logo (the loading one) then hit reset and try again
At the Windows Startup page, select Safe Mode and press enter twice.
Windows will now load. Go into Device Manager (Start-Settings-Control Panel-System-Device Manager)
Select the video card, and uninstall it.
Reinstall your video card using the Installer package (if it's ATI or nVidia)
If this dosn't work, then post back and we will try something else

I think you are experiencing something that happens a lot when you change monitors, possibly 'downsizing'? Your graphics settings on your actual PC were set too high for the new, smaller flat-screen, so what you'll have to do is hook it back up to another monitor, even an older CRT-style one, and then do the following steps before hooking it back up to your new 14" LCD:
boot into Windows as usual, but on an older, perhaps larger monitor
right-click on any empty area on your desktop, then left-click on 'Properties' at the bottom of the little pull-down menu that pops up
when 'Display Properties' window comes up, click on the very last tab to the right, labelled ''Settings'
find the 'Screen Resolution' slider bar about two-thirds the way down that window, and adjust the slider control to a more standardized, universal setting, like '800x600', or even '1024x786'. Either of those should work with your new LCD flatscreen.
make sure you click 'OK' on that window, then 'Shut Down' Windows properly (using the Start button, and all that)
disconnect your old monitor, and hook your new one back up. It should work!
This happens a lot. I build HTPCs, so it's even worse the more 'options' you have, believe me.
Hope this helps!
Symptom : No images on the screen. I cannot turn on the monitor.
Checklist 1 : Is the power cord connecte properly.
Action : Check the power cord connection and supply.
Checklist 2 : Can you see "Check Signal Cable" on the screen ?
Action : (Connected using the D-sub cable)
Check the signal cable connection.
Checklist 3 : If the power is on, reboot the computer to see the initial screen (login screen), which can be seen.
Action : If the initial screen( the login screen) appears, boot the computer in the applicable mode (the safe mode for Windows ME/XP?2000) and then change the frequency of the video card.
Note : If the initial screen does not appear, contact the Service Center or your dealer.
Checklist 4 : Can you see "Not OPtimum Mode", "Recommended Mode 1440 X 900 60 Hz" on the screen.
Action : You can see this message when the signal from the video card exceeds the maximum resolution and frequency that the monitor can handle properly.
Adjust the maximum resolution and frequency that the monitor can handle properly.
Checklist 5 : There is no image on the screen. Is the power indicator on the monitor blinking at 1 second intervals ?
Action : The monitor is in Powersafe mode.
Press a key on the keyboard activate the monitor and restore the image on the screen.
If there is still no image on the screen, press the On button. Then press any key on the keyboard again to activate the monitor and restore the image on the screen.
If the monitor displays POST messages as it boots, then your monitor is still working. It would appear that either your video card or your monitor settings need fixing. Try booting Windows in SAFE MODE and go to Control Panel. Select Display Settings and uninstall the existing driver for your video card.
Reboot your machine. Windows should detect your video card and install its proper drivers. If you've gotten this far, your monitor is working.
Failing the above, reboot in SAFE MODE again and this time uninstall your monitor. Try rebooting again and Windows should again detect, configure and install your monitor appropriately.
You need to lower the resolution into the monitor's range. 1024x768 is the usual safe one. Now, if you could tell the operationg system you are running it would be a little easier to help. I'm going to assume it's xp for now. You need to plug a different monitor into the computer, preferably a CRT, as they support a HUGE range of resolutions. Then you schould be able to see the screen. Right click on the desktop and click properties. Click on the settings tab on the far right of the new window. Now you should see a resolution dropdown. Change it to 1024x768 and click OK. Go ahead and plug the LCD back in and you should be good to go.
Well, I noticed this after I installed win xp sp3. My monitor won't turn offwhen I click the button. I have to set my power setting to a certain timeframe then require a relogin but the monitor just won't turn off otherwise.
