After installing this, I noticed serious problems typing at normal speeds. This KVM will either drop or transpose characters as you type them, for some peculiar reason. As a consequence, I find myself plugging my keyboard into the machine I wish to use manually, almost defeating the point of having this.
Switching between machines will work, but perhaps because they do not feed any information between the machine from which you've switch and the now-missing displays, something seems to get reset, and you find yourself having to fiddle with settings when you return.
It does maintain good video quality (otherwise), and not a problem with the mouse.
The keyboard issue is serious enough to warrant a 2 star rating instead of the 4 stars I would otherwise give this.
Been looking after lots of these devices for several weeks now and no end of problems. Problems: have to type each key twice at bios level, screens go blank when lost focus or go into powersave mode. Have to switch PC off/on to get video output again. remote desktop comes inactive at times when trying to connect to remote server, have to close down and reopen. These are just a few of the issues, very poor performance for what should be a simple product.
I bought this after speaking with Startech's support team, which while they didn't really know a lot about this product, were generally helpful. First the Good news. Supports DisplayPort to legacy adapters very well. I'm running a 30" Apple monitor (w/powered adapter) and 27" hdmi (passive adapter) between two macs. No video problems. Now the Bad news: The unit doesn't recognize a mac keyboard, (according to StarTech support "no KVM does")so in addition of not being able to use the HOT key switching, the unit won't even pass keystrokes from the dedicated keyboard usb in to either or both machines (I got inconsistent results from this- I tried 2 units). Fortunately, the hub works just fine, so if you place the unit where you can reach it, it will perform well (just don't use the dedicated keyboard or mouse inputs). The unit is well priced at amazon and rakuten, and compared to other solutions (which also have their own issues) it's at least workable. Would hope that their Asian development partners start supporting Macintosh products. There are more than just cheap PC's out there!
