Question about Compaq (242697-001) 8-port KVM Switch

KVM Monitor resolution out of frequency and will not display

I have a Compaq 8 port kvm (242809-003 or compaq spares 242697-001) and cannot view the monitor when my laptop is connected to the port.  It did work previously, now all I get is an out of frequency message.  The KVM monitor will work for all other ports if I reboot the kvm and avoid attempting to display the laptop.  However this is my daily use computer and I need access to it.

This occurred when I made a monitor resolution change in properties and it was applied automatically without offering a chance to accept or reject the setting.  Now the only thing that appears is the out of frequency message.

I have checked the laptop when not connected to the kvm and it has the correct (previous) setting.  I have rebooted both the kvm and laptop.  I have checked the laptop settings in safe mode (note KVM monitor will display the laptop in safemode).  I installed the laptop on a different port on the kvm and still all I get is out of frequency.  Any suggestions!

Re: KVM Monitor resolution out of frequency and will not...

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

I have avocent switchview 1000 8 port. it has been working ok for over a year. On monday I found that 4 computers are not displaying 2 windows 2003 server, 1 windows 2008 and 1 xp. I have tried switching...

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?

Compaq 8 port kvm switch

You Compaq unit is proabably a rebadged Avocent like my HP Analogue KVM. To open the menu on that, you simply press the Print Screen button to open the onscreen menu.

Hope this helps.

How to set up Compaq Series 4110 8-port KVM Switch & select computer

The Compaq 4110 KVM switch was actually manufactured by Apex which is now part of Avocent. Your switch is Compaq's rebranding of the Apex/Outlook EL-80DT from Avocent.

The key to display the KVM switch menu should be PrintScreen. Here is a link to the user manual:

HP Parts supposedly still stocks the EPROM for this model, so you can try to order it from the HP Parts Store. Check for part 340579-001.

Compaq 8 Port KVM Switch 147094-001

Funny... I was reading about something like this for an HP KVM I' looking at buying... I can't find ANY documentation for that older model. But I did find a forum that gave advisement on how to switch the ports from system to system.

Read this and give it a try:
"Try print screen, then the port number to which you want to switch, then enter.

I copied and pasted it into a text file for myself in case it's the correct method for the KVM I'm going to buy here soon. :)

Perhaps the models are similar enough that it'll work.

Please let me know because I am quite curious to see if this will work. I would imagine that there is a universal standard somehow.

I'll be watching.

Out of frequency


Are you referring to a problem with a Compaq (242697-001) 8-port KVM Switch or on your display (projector?)?

If it is a display problem, start your PC in Safe Mode and go to your Display Properties. In the Settings tab, lower down your screen resolution and color quality. In the Advanced button, Monitor tab, lower down your Screen refresh rates.

Reboot. Do the same and increase settings slowly (by increments) till you get the "out of frequency" message again. Pressing escape would revert you back to the last setting that worked fine.

Hope this be of some help to you, otherwise pls post back with a more detailed description.

Good luck and kind regards.

This is a fairly common occurrence, typically due to signal loss. The longer the total cable run (monitor to computer connector) the less loss you will have. The longest KVM to computer cable I can use reliably these days is about 12-15? at 1024 x 768 at 32 bit color or 8? for 1280 x 1024 at 32 bit color. Things you can do to reduce loss: -Reduce the length of the total cable run. -Increase the quality of the cables used. I only use low loss cables now and have far fewer issues. -Change the video card, some cards can push a signal a longer distance that others. -Reduce the resolution/colors the video card displays. -Try a different monitor or if possible use a different (low loss) cable to connect the monitor to the KVM. Let us know how it turns out or if you have any other questions.
