Pretty cheap for features, but you get what you pay for
20 November 2010
Summary: There are very few items I give a “poor” review to but this unfortunately must be one. After months of ownership and hopes that it will eventually work right I just regret having purchased this thing. I originally got it so I could work from my work docked laptop or my personal laptop on the same keyboard/monitor/mouse I use on my desktop.
Pros: • 4 Ports • dual monitor • USB support • speaker/microphone connections • Cheaper than many comparable units • Won’t murder you in your sleep
Cons: • At the “maximum” DVI Resolution (1920x1200) the screen is fuzzy, wavy and sometimes has scattered pixel distortions of solid RGB colors. I often have to switch to an empty port then back to “reset” it so I can see the screen. On my laptop’s dock it CAN’T go at this resolution, it’s constantly flickering off then on every couple seconds. • The audio is dramatically distorted over connecting directly to the speakers. Lots of background buzzing if you turn the sound up...
Summary: I tried following the advice here and upgrade the firmware. It took me a while to find it on the manufacturers website. The instructions were horrible. I did it anyway. That did not fix the mouse problem. Then I discovered the FW I installed, "latest" from the website, is v. 1.03 whereas the original shipped with it was v. 1.04. There was no way to email the company, so I used the Live Chat feature.
Pros: DVI + VGA + USB Needed something for several computers, each with a dual display, and this works, well - sort of
Cons: It was not the easiest to install. The USB mouse did not work on any of the computers. Tried plugging it through the USB hub instead of the mouse hookup and it worked. Observed some erratic behavior while switching, e.g. , a computer reboots for no apparent reason.
Summary: I have never tried the audio/mic switching, so I can't comment on its functionality. Like I mentioned above, monitor switching has always been rock solid. Now keyboard and mouse switching seem solid with no noticeable delay when switching.
Pros: Finally! It now works correctly AFTER updating the firmware located in the drivers download from the product home page. I have been using this switch for over 6 months at work and it has never worked correctly. I too suffered the same problems others experienced with the sticky keys, Alt-Tab not working, etc. After 1 hour of putting up with that initially I just gave up on using the dedicated mouse and keyboard USB ports and used the additional two general purpose por...
Cons: 1-Firmware shouldn't have been released in the Driver package. I remember looking at the manufacturer's product page right after I got it. I didn't see anything about firmware in the downloads section, so I figured they didn't have any firmware updates. 2-After upgrading the firmware, I still show the same version. Perhaps they just consider this a patch rather than a new version, which seems a little weird...oh well, as long as it works.
Summary: Sometimes you will need a PS2 Keyboard or Mouse as some systems have difficulty with USB only, especially older systems.
Pros: Bought this unit from another vendor and it has been outstanding. Never had any of the issues that the other reviewer had with it repeating keys. We use it in our computer lab all day long to switch between customer computers.
Summary: these problems are present on two of these kvm switches we purchased - bot are going backkkkkkkkkkkkkk.
Pros: It works and switches between vga and dvi - excellent
Cons: when typing, this KVM switch skips keystrokes, repeats keystrokes, and far to often will repeat the last letterrrrrrrrrrrrr or twowowowowowo that you typed until you hit the backspace keyeyeyeyey. While that was meant to be funny and/or amusing, it is in fact what is happening.
