How to make two laptops share the same external monitor?

I have two laptops which I need to connect (one at the time of course) to the same external high-resolution LCD monitor (Dell Ultrasharp 21") in 1600x1200 mode.  I tried a hardware switch from my local computer store (2-in, 1-out), but I get ghost reflections. I need some kind of high-quality switch as this monitor is used for photography processing and I definitely don't want any ghost image.

Thanks in advance for your help,

Serge

You need an electronically controlled KVM.

Also, the cabling that you use should be as short as possible.  You are losing signal for every inch that your broadcast travels.

irwinpks,

Could you be more explicit on the brand?  A friend of mine used the Belkin KVM with quality short cables and had ghost images at resolution of 1200 and up.

Tx,

If you're pushing quality then you may want to consider Rose products

The cost of the extender & kvm could be as much or even more than a new LCD display

I use a DLink KVM, similar to http://www.dlink.com/products/?pid=307&sec=0.  The specs support very high resolutions; you may want to test your VGA cables by swapping them to see if they can handle the higher bandwidth.
