No video signal to external flat panel monitor

by rpapworth1 / October 25, 2006 11:03 PM PDT

I am trying to determine if I have a problem at the computer or the flat panel tv/monitor I am trying to hook up. The flat panel worked the first time I hooked it up, but after that it gives me a ''no video signal''. I have hooked the computer (laptop)to a second flat panel tv/monitor, and get the same message, so am thinking it is output from computer, but don't know how to check it out.

Your display is most likely set to a resolution and/or refresh rate that your monitor cannot handle. For example, a 17" and 19" LCD monitor can only handle a rseolution up to and including 1280x1024 dpi. A setting one notch above that will give you that notice and not display a thing.

If you haven't adjusted the resolution prior to it not working, check the video cable. If that's not the problem, you need to find the key on your keyboard that says "fn" on it and hold that down while you press the key that has the blue outlined picture of a monitor on it. The display should switch to mirror your laptop's display or black out the laptop monitor and display the picture on the flat panel.

Z, thanks for the heads up. I will give that a try.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
