Hot-Key Commands You can change ports on the switchthrough the simple Hot-Key commands using the "SCROLL LOCK" key and the UP and DOWN arrow keys. 1. To invoke the Hot-Key mode, Press the "SCROLL LOCK" key twice within two seconds. 2. Press the UP or DOWN arrow keys to switch to the previous or next port respectively.
Alternatively you can directly switch the KVM focus to any computer by entering the switch port number. Ex. press "SCROLL LOCK" "SCROLL LOCK" 2 and the computer on port two will be selected.

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.
Try swapping the KVM cables from the 2008 computer into the Vista computer and see if the problem follows the 2008 computer. This KVM gets the drivers it needs from the OS and the IOGear web site does not show any support for 2008.
the way the kvm switches works is you have your mouse/keyboard and monitor plugged into the switch then you have the cables connecting to where you would have your mouse/keyboard on your pc, youll be using the same keyboard/mouse and monitor to run 2 pc's. there will be rather a switch to move between the pc's or like the 1 i use i have tp press ctrl the number 2 twice.
Press Scroll Lock two times within two seconds. Then press the Arrow keys, up or down to switch between ports. Or press Scroll Lock two times and the press the number One or Two key to switch between ports.
The monitor is not detecting the video signal from your computer. Assuming both of your computer video cards have been tested and really work I would try the following:
Try switching the cable sets that connect the PCs to the switch. If the problem follows the cable set then it?s likely the cause. If not then try switching the cables that plug into the switch so that PC#1 is now connected to the port where PC#2 originally was and vice versa. Again if the problem stays at the same position then I would suspect a defective switchbox. If it doesn?t then you probably have an issue with one of your PCs video cards.
I know this is two months late but perhaps but hope this helps you or someone else researching a similar problem.
If you are sure the left monitor?s power is not the source of the problem it does sound like a shielding or excessive signal loss in a device/cable.
If it?s always the left monitor I would try unplugging the video cable that goes from the left monitor and plug it into the right monitor; do the same with the other monitor. If the problem moves to the right monitor then that eliminates the monitors and we move on. If the problem goes away then probably one monitor had more signal degradation than the other. If the problem stays then the monitor is the source of the problem.
If the problem followed the cable then I would exchange the cables that run from the switch to the monitors; if nothing changes exchange the cables that run from the switch to the PCs. If exchanging any of these cables results in the problem moving then you have a damaged cable or a bad connection.
If the problem is still on the left monitor unplug the cables from the left PC that run from it to the switch and plug them into the right PC; do the same to the right PC. If the problem moves then you might have a damaged switch OR perhaps the video card output on one of the PCs is weaker than the other.
All cables and devices weaken the video signal to some degree but the amounts can differ wildly. Over the years I?ve had this problem caused by cables, switchboxes, video cards, radio transmitters, bent connector pins, poor connections, excessive cable lengths, monitors and accumulative signal loss from several devices. The last is the hardest to diagnose.
Good luck and let us know what happens.
