KVM switch and Desktop Monitor Issue

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.

SOURCE: KVM Switch Issue

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:

  1. Laptop display only
  2. External display only
  3. Laptop+External clone
  4. Laptop display + extended desktop on external display (dual monitor setup)
Check your laptop display settings and make sure that it's not in presentation mode (options 2-4) before connecting the KVM switch to it. It may be recognizing the KVM switch as an external display in option 4 mode.

My Windows XP is connected to my Epson Powerlite S3, but the screen is blue with the words Source: Computer (Auto) No Signal on it. When I click "Help" on the projector, it takes me to a screen...


'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 :)

I've got a 4 port switch with two computers hooked up - a desktop and a Lenovo Thinkpad R60 laptop - the desktop works perfect but when I switch to the laptop only the keyboard works - no video or mouse


The Thinkpad does not divert the video automatically to the external monitor via the KVM switch, you need to divert the video by pressing on the Fn key and the press the F7 key to toggle between the Thinkpad's LCD screen and the video port/external monitor. You may need to use a separate USB mouse connected to the Thinkpad.

What resolution are you using? And if you place the Avocent KVM cable to a different port, do you get a signal? If you use a Known good cable do you get a KVM session with good video?

Dual Screens with a VGA connection


The easiest way would be to purchase a video card that has 2 vga ports on it, allowing dual monitor support. Here is an example.

When a computer first boots up the video card send a request to the monitor to find on what resolutions the monitor supports. If the video does not get a response the card will default to very low resolutions. The only way to avoid this problem is to boot your computers one at time and keep the KVM on the computer until it fully boots to a desktop. This will allow the KVM to pass the monitor information to the computer.

Wobbly screen on mac laptop


are you using a Mac Mini-DVI to DVI adapter or any adapters? This is a VGA video output type of KVM switch so probably the problem is with the adapters involved to it.

I guessing that since **-one responded you've given up and returned the whole mess but what the hey.

A lot depends on the KVM you're using. There are some high end units that will match different sources to the monitor but most work best with matched input and output. Unless you's specifically states that it will convert analog to digital it won't. So if it's an analog KVM then both the computer video boards need to have an analog VGA jack and the monitor does too. If the KVM is ditital you need to have all the systems and monitor digital. Savi? The Monitor may support boath analog and digital input but NOT at the same time. You can't plug in two computers at the same time, that's what the KVM is for.

The bottom line here is that you typically need to run the least common de**minator to use a KVM. Also, if the computers have different frequency (resolution) out put and you hit the KVM switch then the monitor will freak out. Some monitors will auto-switch between frequencies but most don't (especially the cheapies).

There are adapters that will down convert digital to analog. If you're dead set on using the KVM with that old Dell then you may need to plug the down converter into the Acer Video Board but you'll loose the high resolution and sharp picture from the digital video. If it was me and I had to use the KVM, I'd get a cheap digital video card for the Dell or just run two monitors.

I run 5 systems on my desk, Three of which are older servers with analog video. They share an analog KVM with video and keyboard on the wall. The other two systems are current generation and share a KVM and 27" flat panel center desk. I also have a laptop that hangs on the other wall with a laser blue tooth keyboard on the other side of my desk. Now if my wife would only let me turn part of her craft studio into a server room.....

KVM Monitor resolution out of frequency and will not display


Restart your system in a VGA mode (you will find this below Safe Mode, by pressing F8 before windows is loading) This way yours screen resolution will be at the very low frequency then you can change it back to the resolution you like. Eg. 800x600 or 1024x768. Remember to keep your Screen refresh rate lower like 75Mhz
