Summary: This is overall an okay KVM switch. It does the job with no hassle, but when I got it, one of the VGA cables was broken. Also, in case your computers cannot provide enough power to the switch, you need to purchase your own Power Supply for it, since it does not come with one.
Pros: Cheap, Hot Key Switching
Cons: Cable was DOA, Instructions Unclear, You Have To Provide Your own PSU.
Pros: Worked fine at first with a hickup now and then losing the mouse when switching between computers.
Cons: Now after about a month of using it running multiple different computers it's dropping the mouse constantly, I might be able to switch between computers 3 or 4 times before the mouse stops working.
Summary: Background on the DDC... All modern graphics card drivers (on all modern OSes) use the DDC to detect the monitor's supported video mode(s). Without it, the graphics driver makes a guess, and usually it's either way too low (800x600) or the monitor can't display it.
Pros: Cheapest 4-port KVM that I have found anywhere. Has dedicated button to switch inputs so you don't have to use the keyboard if you don't want to.
Cons: Both the KVM switchbox and its cables are missing the DDC signals! I did a careful A-B comparison with known good cables to confirm this. Worse, the video quality is horrible: ghost images, sparkly pixels, slowly scrolling noise artifacts, etc. The noise is most noticeable on an all-black screen....
Pros: Work good, the channels don't come in with all the same video quality, but for the price, it allows me to monitor the activity of multiple CPU's, set up is very easy, I don't use PS/2 mouse so I have a coulpe of mice around, but work good. Low tech solution for space savings.
Cons: Don't intend to use for high video apps/games
Pros: I've been using kvm's from a variety of vendors since 1992 and this is the best set of features I've seen in such an inexpensive model. Works as advertised.
Cons: In my mind I took off a star for short cables and the annoying beep when switching machines whether using the button or hot keys (hope I figure out a way to turn that off). However, I'm sticking with 5 stars because for the price this is a very good kvm.
Summary: I would recommend it as a means of gaining desk space as well as a power saver. It looks cheap but it's worked fine for me, and I'm constantly switching between 4 computers.
Pros: I've had it 4 months and it's working fine. Much more room after removing 3 monitors!
Cons: Be careful when installing, to be on the safe side don't plug in new computers with it already running. Make all your connections then power on. I had an E-machine suddenly stop working after I made that mistake, but it was an e-machine so no big loss.
Summary: The only reason I made my first was I had been misinformed as to the cost. I thought a 4-port would cost between $300-$450! I just wish I had checked sooner!!
Pros: This is the perfect KVM for most, I made my first KVM, but it switched more than keyboard, video, and mouse. It also had stereo audio speakers, stereo audio mic, and one USB port. In most cases you only need to switch "KVM". All the others are hot-plug anyway
Cons: The only thing I've found so far is the cables could stand to be longer.
Summary: I tried all combinations of booting the other PCs also into dual-boot O/S's and it worked flawlessly--switching is OK but video is no good. I'm using a fairly old HANNS-G HW191D wide-screen 19" LCD monitor at the above specs, a nice IBM KBD, and a nice MS optical roller mouse.
Pros: Nicely packaged, looked good at first. Very nice cable set.
Cons: Hooked it up to 3 of my PC computers one of which is a dual-boot (V32 Business & V64). This switch switched perfectly upon booting my main PC, but the video very much ghosted, was poorly focused, and showed horizontal noise bars rising up the screen. I worked vigorously on my NVIDIA settings for ...
