5 out of 5 eggsDoes the job well

Pros: Supports four DIV-I (dual link) systems in a dual monitor set up
Will support resolutions up to 1080P (maybe higher but my monitors only go to 1080P)
Supports PS/2 keyboards and mice
Fast switching on PS/2 ports, monitors will depend on specs of the monitor.

Cons: Supplied cables, while very high quality, will only support DVI-I and not DVI-D. If you have a card that has DVI-D, you will need a separate cable. The KVM will work with DVI-D cables as they are only missing the analog signal. The analog signal is irrelevant if you are using digital monitors. LINKSKEY, recommend you provide a few DVI-I to DVI-D adapters so the DVI-I cable can be used to connect to a DVI-D port.

Other Thoughts: I have seen some reviewers giving bad reviews to this device because it will not support new mice. Before you buy, read the specs. This KVM supports PS/2 devices. This means the KVM will not recognize or transmit the UBS signals to the CPU. PS/2 ports do not communicate with the CPU directly, they have an assigned IRQ that only communicates with the CPU when they need to. This means they do not take up CPU cycles when not in use like USB devices. If you have USB keyboards or mice, do not buy this KVM. You will likely have to spend more money on a different KVM to support them (different technology required to ensure the USB can communicate seamlessly between systems, OSs don't really like UBS devices to be shut off like PS/2. A disconnected PS/2 device will not be noticed by the OS as the OS will only look for their input when the IRQ initiates). I have seen a few, but none that have dual DVI-I ports. They will be very hard to find.

Bottom line, PS/2 devices work much better than any USB input device in a KVM set up. If you need a KVM, recommend using PS/2 mice and keyboards as they will work better than USB, even if you are using a KVM with USB.

5 out of 5 eggsWorks great

Pros: As other comments suggest, this handles larger resolutions than what the documentation suggests. I'm running dual ASUS ProArt 24" monitors, at 1920x1200 resolution, with some DVI-I to DVI-D converters, with no problems. Just plug it in and it works.

Cons: Unit is rather bulky and not the nicest design in the world, but it works great at a decent price so I don't really care what it looks like.

2 out of 5 eggsNo support for latest mice

Pros: Dual monitor DVI with high resolution

Cons: Does not appear to support the Microsoft Comfort Optical mouse (it is a PS/2 mouse). Windows just simply doesn't recognize it.

Other Thoughts: I don't see a firmware update or anything on this site

5 out of 5 eggsNow supports 1920x1200

Pros: It works perfectly and can do 1920x1200. Because it has ALL the cables you'll need it came in a huge box.

Cons: .

Other Thoughts: The BETTER part. I went looking for a 2nd 22" monitor. a 23" monitors for a little more, then 24" for a little more... Next thing I knew I bought a 26" monitor. :-) After ordering I realized the 1920x1200 is way out of the listed specs so I emailed Linkskey. I asked what would happen if I tried to use it at that resolution. They wrote back: "The current version supports 1920x1200. The website will be updated soon." Sweet. :-)

2 out of 5 eggsFrustrating KVM

Pros: Moderatly priced dual KVM Switch with high quality construction.

Cons: The design logic is faulty. In order for this KVM to see a computer it must be switched to point that computer when it (the computer) is powered on. Every other KVM I have used will see a computer that is powered on; whether or not it was pointed at the computer when powering up. Just wait until you power up one of your PCs and then have to shut down and restart in order for this KVM to see it. The process is both frustrating and time consuming.

The 4 cables are all the same length - a length which is unspecified on the NewEgg and Linkskey websites (8'). Varying lenghts would make much more sense (to me at least).

Should be shipped with rack mount brackets (that I could then adapt for shelf mounting).

Cannot switch forward and backward from the KVM's manual button (forward only).

Other Thoughts: Ugly Graphics, poorly described functionality, etc. in NewEgg and Linkskey website narratives. As for me, I would have gladly paid more for a better thought out KVM design.

5 out of 5 eggsBest DVI Bang per $

Pros: KVMs are problematic, PERIOD! This one works nicely in 1600 X 1200 and works in gaming as well. There's not a lot of info out there on DVI KVMs. This KVM works well with my Logitech MX3100 (MX1000 mouse) and even maintains the mouses back/forward browser functions. This has been a huge issue and has a lot to do with my KVM "collection". Overall a fine product, so far, since I've owned it about six months. Excellent quality cables which should be considered when factoring the overall price of your KVM.

Cons: The box is pretty ugly. Logitech's drivers are iffy at best but they "don't support KVMs". Microsoft's intellipoints work nicely with the MX1000 and this KVM. Sometimes the monitor is only recognized as a generic monitor. No big deal. The cables seem to have issues with Nvidia graphics cards. They work but the two screws aren't long enough to engage the "nuts" on the my 6600GT. I hated that card anyway and ATI cards work fine. As far as forward compatabilty PS2 mice/keyboards and ports are supposed to be legacy technology and might well be on the way out. Something to think about when contemplating a $270 switch.

Other Thoughts: KVMs aren't perfect. Dual DVI KVMs can cost thousands. For the money this one is fantastic. It just quietly works like a switch should. Best bang per $ out there. I spent months researching and soul searching over this purchase. No regrets!

5 out of 5 eggsWorks great!

Pros: Works as described. Able to handle 1600x1200! Cheapest dual dvi kvm you'll find that can handle 1600x1200.

Cons: Can't switch screens during boot.
Occasionally when switching between 2 particular computers, the screen gets moved to the right by 1/2", toggling the DVI/VGA input switch restores the correct video.

Other Thoughts: Don't be confused by the cheaper versions of this model. If you want 1600x1200 on each screen you need this one, the enhanced version.
This is a digital only kvm(per specs), vga adapters will not work with this. You need native DVI.

2 out of 5 eggsUnreliable KVM

Pros: Dual DVI.

Cons: PS/2. Logitech SetPoint driver is lost each time I switch between computers. Sometimes video signal is garbled, or ceases priodically, or is "out of range". When starting a computer, it must be selected in KVM from POST until the video driver is completley loaded. (Otherwise the computer will not be recognized by KVM.)

Other Thoughts: This KVM does not accept analog signal. All the necessary cables are included. Length is 2m (6.6'). But their ivory color does not match with the color of KVM at all. Design and color of KVM are mediocre.

In general this KVM is not reliable. It seems that I have to stick to a dual VGA KVM for a while until a reliable DVI KVM is released.

4 out of 5 eggsGood product - weak quality control

Pros: Dual-DVI monitor support; heavy-duty cables; good overall design and feature set.

Cons: The manufacturer's quality control is a little shaky. The first unit I got was defective. I could only get one monitor working at a time, and only briefly before the colors would distort. Newegg RMA process was excellent! Second unit has worked fine for almost a year.

Other Thoughts: The connections have to be screwed down very tight on the switch box or the monitors get no signal. Great prodect if only LinksKey could get their QC act together.

5 out of 5 eggsLinksKey NOT Linksys

Comments: <a href='http://www.linkskey.com/kvm/ldv-dm04esk.htm' target=_blank>http://www.linkskey.com/kvm/ldv-dm04esk.htm</a>

Had I realized it was a LinksKey, I'm not sure I would have bought it. But it actually works great. The included cables were nice hefty cables with ferrite chokes (much nicer than the ones that were included with the monitors - Samsung 213T's). You get two replacement cables for both your LCDs and four sets of DVI cables molded with ps/2 cables. Image quality is great (dual 1600x1200@60Hz).

The ps/2 to USB adapter (for the Mac) also works fine through this box.
