ATEN CS1764A 4-Port USB2.0 DVI KVMP Switch, Cables Included

Pros: hasn't exploded yet.

Cons: Won't accept my Corsair keyboard, won't switch peripherals when a computer goes offline, wireless mice are hit and miss. Have to power it down regularly to even get it to function. Too expensive for something that doesn't work.

Other Thoughts: Don't bother buying this thing. I've been trying to get it to function somehow since day one. Finally switching back to my 2 port kvm, since 2 computers is better than none.

Pros: Low price, nice cable sets, solid construction, no problems with video

Cons: I leave the switch on 24/7 but often shut-down one or more computers connected to the switch and when systems are restarted the switch usually does not recongnize the mouse. Have to unplug/plug mouse, doesn't matter if wired or wireless mouse. Also have updated firmware to latest version (as of 11/01/2012) and that did not resolve issue.

Pros: It supports my hi-res monitor. Previous KVM was a Black Box KV824A. It did not have DVI ports and what it did have did not support my Samsung 2343 2048x1152 monitor. The screen images were always a bit fuzzy. With the Aten, everything is tack sharp. Came with full set of cables including audio pink and green.

Cons: A bit expensive, but my eyes are happy now.

Pros: Good quality and solid construction. Cables provided were very nice.
Worked as advertised with my Windows 7 machine.

Cons: I purchased this KVM because it listed it was compatible with Linux. However I have three Linux machines that all displayed the same behavior while the unit was in place:
The Keyboard does not function.

Mouse worked, video looked good. I was unable to type in a user name and password. Remove the KVM switch from the equation and everything worked like normal.

Other Thoughts: Was not able to consistently get into BIOS or Quick Boot menu by pressing "DEL" key or "F8" key while KVM was installed. Sometimes it worked, but mostly it did not, again this does not work for me as most of my machines have multiple hard drives with different operating systems to choose from while booting from the quick boot menu.

Pros: Sturdy construction, functions exactly as advertised.

Cons: A tad pricey, but you get what you pay for...

Other Thoughts: I'm glad I spent a bit more for this switch over some of the cheaper offerings.

Pros: Unbeatable DVI quality @ 1920 with zero lag. Yes, you can run the most visually-demanding games with this switch and see virtually every frame as if you were connected directly.
Solid, heavy construction.

Cons: hardware compatibility.

**DO NOT** even think about buying this switch if you intend on connecting it to *anything* that uses a standard 15-pin analog video connector DESPITE what the description on Newegg states. The outputs/inputs on the switch are DVI-only and no number of adapters or jerry-rigging (short of a solution that involves soldering) will allow an analog signal of any kind.

While this switch has an absolutely flawless 1920 signal, **IF YOU ARE A GAMER** and your game requires the use of more than 2 mouse buttons (or you're like me and have become fond of using the mouse wheel button as a "double-click" alternative), you will be completely out of luck with this switch.

Other Thoughts: Wish I had paid attention to other reviews regarding analog. For the money, I could have picked up something else that supported more hardware. Good device overall, but would not be my first choice given a redo.

Pros: Easy to setup and get working and easy to use once you get it setup. It has a small footprint so will fit on your desk without too much problem. It comes with all the cables you will need to connect 4 DVI-enabled computers. The switchbox and cables seem to be quality made.

Cons: Cables are a bit short and are rather stiff, but they work. Sometimes you have to hit the switch twice to get it to change to the computer you want to be active. I wish it had a power on/off switch on it.

Other Thoughts: I have it configured with an older Dell Dimension (XPS), new Dell XPS, and an HP docking station with an HP laptop. The switch box sits on my desktop and I use the switches on the box to change between computers instead of the mouse or keyboard hot keys. I would definitely consider buying another one of these and would recommend it to others.

Pros: Based on the other reviews, I decided to give this KVM a try, and I'm glad I did. Here's what I like:

* Comes with four DVI KVM cables
* Supports HDCP
* Remembers device capabilities
(this allows me to reboot a system without it being the active display)
* Flawlessly handles my G11 keyboard (including multimedia and extra function keys) and wireless Trackman wheel
* No screen glitching at 1920x1200
* Has never locked up

Cons: My only complaint (a very minor one) is that it takes four key presses to switch displays rather than three. For example, to go to port 2, you have to press <Scroll Lock><Scroll Lock>2<Enter>. I'd rather not have to press <Enter> at the end.

Other Thoughts: Overall, this is a very solid and stable piece of hardware, and I highly recommend it. I've never had a KVM before that's worked so well for me.

Pros: Still working with no major issues.

Cons: Nothing that would stop me from recommending it to a friend.

Other Thoughts: I use this on my testbed station. As long as one PC is connected, no problem. If no PCs are connected, when you connect one with power to the switch it may hang. Easily fixed by pulling the power plug on the back of the switch for a few seconds and reconnecting.

Pros: The kvm seems pretty decent in most respects.

Cons: The problem I had with this kvm is the lack of easy toggling between computers. I hooked up 2 systems to this 4 port kvm. And I have to hit Scroll Lock - Scroll Lock - Port Number then enter to switch, takes two hands and have to look at keyboard. There is also an option to allow double clicking of the mouse wheel to switch but it can be difficult to double click the mouse wheel, and also it switches to ports that aren't active so i have to double click it 3 times (6 clicks) to switch from 2 -> 1. There doesn't seem to be very much customization on the ways to toggle.

Other Thoughts: If you can handle slightly complex toggling then you probably will like this kvm.
