Cannot invoke hotkey function to switch computers
Make sure your keyboard and mouse are plugged into the correct usb slots on the switch. One is labled for keyboard, and the other for mouse. If you mix these up, those hotkeys will not work! :) Also, a much better hotkey for this switch is to tap scroll-lock twice. This automatically switches, so you don't have to hit multiple buttons.

Make sure your keyboard and mouse are plugged into the right USB ports on the switch. If you plug the keyboard into the mouse USB port the hotkeys will not work! The USB ports on the KVM switch are labeled under each port, with a mouse and keyboard icon respectively.From the Quick Start Guide/Manual:
The Numlock hotkeys are listed as:
[Num Lock]+[-] 
Switches to output 1
[Num Lock]+[-] 
Switches to output 2
Auto-scans and chooses which ever port is connected.
Alternatively: Tap [Scroll Lock] twice to automatically switch between ports.
Note: I've never been able to get the Numlock key combinations to work correctly. I always just use double-tap [Scroll Lock] trick to switch.
If you get stuck with your scroll-lock and Alpha lock lights flashing, just hit [Esc] to fix it.
(Scroll down to "Quick Start Guide" and choose CS62U out of the drop down).

My Altusen Aten CS62U-2 Port USB KVM Switch seems
It very well could be just a cable causing this problem, try switching around the cables to see if you can isolate the issue. It could be the KVM is not compatible with your monitors refresh rate though, I have seen this happen a good number of times. It will work but will blink randomly to allow the monitor to re-sync with the video card.. . I have a monitor currently on a kvm that does this exact thing. You may want to try another KVM if you can't get it narrowed down to certain cables.. there is a chance the actual KVM is causing this issue, but is not defective, it is just at a different frequency then the monitor.
Thanks so much
