Question about Computers & Internet
I had the desktop computer and laptop successfully working through a KVM switch, but when I changed the resolution on the monitor through the desktop computer, the monitor blanked out and gave me the message that "Input Signal Out of Range." I unplugged the monitor from the KVM switch and plugged it directly into the computer and it worked fine, so I tried to fix the resolution while it was directly plugged in, but now I get no signal from the desktop to the monitor. I tried to reset the monitor to factory settings from the menu of the monitor, but nothing happened. Under the information menu on the monitor it states that the current setting is 1152 x 864 and recommends 1680 x 1050 60hz. Any help anyone can provide would be great.

There is a natural order of things in pc's. It sounds to me like you may have an issue with the pc being just quicker than the lap top and it is loading in a hodge podge way.
I wish I could help you more but I would try going to a ps2 mouse and keyboard if you have the usb type and if not swap these two out as these must pass before the unit will even boot. Also - do you have a slave drive marked cable select? These things upset a delicate balance. I would also email the maker and see if they can help.
For a more definitive answer please send the make - model and operating systems on each pc - lap and desk - also have you done all your updates? Try updating the driver on the KVM website as well. These issues usually are a small matter to get lined out.
Let me know how it goes and send ur pc info

This almost sounds like the display setting on your laptop was changed to an external device. Most laptops are designed to be hooked up to an external display, such as a monitor or projector, specifically for presentations. You can alternate the display options in the following ways:

Tips for a great answer:
'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:
Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!
Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.
Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.
If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)
