"The SPLITMUX-DVI-4 is a nice product. We used it for our audio multitrack workstations on Stand Up To Cancer, a television show, and it worked very well. We used it again last weekend on a taping of a Kathy Griffin special where it also worked well. I showed it to a number of folks on those shows who were quite impressed.
I've spent time trying to get it to fail (because in live television if it can fail, it will) - powering things in the wrong order, connecting and reconnecting things, changing resolutions, and it always seems to deal with it. Its ability to auto-scale anything seems to work very well. The hotkeys and the "hotmouse" functionality, both of which I thought were gimmicks, ended up being the primary user interface. Note - the ability to set our own hotkey combination is important - we ended up using ctrl-alt-windows because that's available. The default of ctrl-alt is used in too many audio workstations.
One nice small feature - our operators all want to use Kensington trackballs, and Kensingtons will not switch smoothly with any KVM, as Kensington will tell you. I've tried almost all of them. The SPLITMUX unit keeps the connection so when we switch to a computer, the Kensington is operational. Whatever you're doing with the Kensington HID, it works.
Thanks for your policy of demoing this unit - that sold us on its abilities. It's been a big hit here."
