You were probably expecting something more high tech but I use these even with my 30" Dual Link displays.



They do degrade the signal a *bit* - so if you are going to run dual link DVI out near the max (around 10 feet with regular cables) then be wary of trying to push it to 15 or 20. At normal distances, everything should be fine.

If you buy more then 3 or 4, you can get a discount.

They don't do VGA but there are PLENTY of A/B Boxes out there that work fine - check Monoprice.com - I have no doubt they have plenty.

My 17" monitors have multiple inputs and I just use software to turn on and off the displays such that it auto switches when it detects a signal present on DVI but not on VGA or vice versa. The 30" monitors are single DVI only and do not support that - hence the switches.
