5 out of 5 eggsSo good, I own 3 now.

Pros: An excellent KVM that allows the use of 2 monitors and if using 1 monitor that has a DVI and a VGA port you can have a mix of PCs with either style of output without using any adapters. Fast switching and never losing connectivity and dropping any of the PCs. See Other Thoughts!

Cons: Better documentation with the KVM would be very helpful and solve the problems people are having before they have them.

Other Thoughts: First I must say their customer support is excellent in spite of what others have said. I sent an email about problems I was having. I got a call on my voice mail from one of their reps saying his email to me was rejected by our anti-spam service (which we hate). He left me a phone number to call him back. That is rare. He worked with me all my problems were resolved.

Second, the problems.
All the issues I see people are having I had also until the rep taught me some things.

Be sure to install the KVM in the sequence that is in the instructions.

The power supply for the KVM is to power the USB hub only. Many old and some new systems have no or unstable power on their USB ports and will cause the dropping of the PC when switching the KVM. Connect your mouse and keyboard to the USB hub on the KVM and that's resolved.

The next thing to do is to check the settings in the Power Plan on the PCs. For "USB Settings" set "USB Selective Suspend" to Disable other wise the keyboard or mouse will not be able to wake the system up.

After I made these changes I've had no problems at all.

4 out of 5 eggsWorks so far

Pros: It supports 2 monitors, which is hard to find. It switches relatively fast. The picture is normal as I used to have with IO gear KVM. I had to switch because IO gear did not support dual monitor.

Cons: I have this unit 3 to 4 months. As other reviews pointed out, I have experienced several episodes of freezing. The unit stops responding, the bottom for port 1 remains on and there is no way to switch to other ports, also keyboard and mouth not responding. When it happens (I had it happen at least 2 times in last month), I have to disable all USB cables. It is very hard to do due to inflexible heavy VGA/DVI cables that prevent unit from turning. The USBs are at the bottom and not accessible unless you turn unit upside down, and it is very hard with heavy VGA/DVIs. I have scratches on my desk now, and unit almost fell when I was trying to connect USBs. The power feeds from the power supply and 1 of my USB cables. I noted that that particular USB is 3.0, while other computers connected with USB 2.0 which do not provide power. I do not know if it is a good idea to let it run this way or if I should rewire it. It also often drops mouse on one of the computers. Requires to disconnect and connect the mouse again. Strangely- I get the sound when USB receiver for the mouse gets disconnected, so computer knows it was disconnected, yet it does not recognize it right away. I also cannot keep the screens set up. If I want to use computer 2, I have to switch KVM to port 2 before computer starts, otherwise, it starts with desktop on the wrong monitor.

Other Thoughts: Still pricey for what it does. Could be better designed. Confusing about power use from USB ports concurrently with power supply.

1 out of 5 eggsDVI issues

Pros: 2 monitors, mixed DVI/VGA and 4 ports computers. good for my needs...

Cons: Read all these reviews carefully, please!. I worked with Linkskey to have the original unit replaced, after the DVI stopped working. Replacement arrived, connected and worked ok at first, but 8 months down the road, the DVI ports are dying..*again*. Absolutely not worth the $399. Plus I paid for it less than 2 years ago...

3 out of 5 eggsDVI AND VGA?

Pros: When brand new? Worked perfectly. Fast switching between monitors, speaker assignment to each computer was flawless, and USB KVM switching was fast and relatively painless. Monitors on DVI and VGA ports worked well and woke up instantly after switching! Keyboard and mouse assignments worked well, virtually no lag after switching. I thought I had reached KVM switching Nirvanna! I was very pleased.

Cons: After 11 months the DVI ports stopped working. I thought my video cards had gone bad. Many hours of diagnostics later I confirmed it was the DVI ports on the KVM unit. Also, it often locked up and would take a complete power down of all computers and disconnecting all connections by reaching around the back of the KVM unit, and disconnecting the usb port connections to all computers, then unplugging the power supply to the KVM unit, then in specific sequence plugging the usb connections back in and powering each of the computers in proper sequence. As time has gone on I have had to do this more and more as it locks up more and more now. As one reviewer already mentioned this is a pain as the connections on the back of the KVM unit are very tightly spaced. I am also using the VGA ports now instead of the DVI ports, by way of DVI to VGA adapters from my video cards to the unit. Keyboard and mouse are now connected separately to each computer. This defeats the purpose of the switch!

Other Thoughts: This was a very expensive unit when I bought it in 2009. It was approx. $200.00 more than it's being offered on Newegg. I am disappointed to say the least. It worked wonderfully at first but now... not so much. Tech support was only marginally helpful as they would not acknowledge the DVI ports stopped working and kept telling me to reset the unit through the process described above. After three years I don't feel I got my money's worth at all. It's no wonder to me the price has gone down so much. I would never buy it again at the original price of over $500.00! If you need a bullet proof KVM Dual Monitor 4 computer switch you might want to think twice about this one.

4 out of 5 eggsNot bad

Pros: Except for the infrequent freeze up, which requires a reset that involves removing the power supply and all usb powered devices from it so that it shuts down, it worked fine for almost a year now.

Cons: I received this as a gift, and it worked fine except for what I stated above, but now the DVI output has died. I've replaced all of the cables and tried 3 different monitors and 2 different computers (thinking it might be a video card) but the DVI is dead. Now I have to go through the RMA process to replace it. That's a pain, because it comes will ALL the cables you need and the manufacturer states that it must be returned complete as when bought...UGH!

Other Thoughts: Over all, works well. My wife got it for $300 almost a year ago. Too bad the DVI input/output died....

3 out of 5 eggsLinkskey

Pros: All 4 work ports work - both monitor ports too. Sound is bad like you'd expect, but don't use that any way.

Cons: USB will drop keyboard and mouse fairly often, generally fixed by quick unplug/replug of USB ab cable.
INSTALL: painful, didnt recognize all units at first, while previous Linkskey kvm *never* had an issue. New KVM was for DVI connections for new computers. Considerable time spent on fiddling with the cables.

3 out of 5 eggsBest I've found, but far from perfect

Pros: - This KVM is much more stable than any other 4-port desktop (single or dual monitor) I've used.
- It's also quite fast with minimal delay when switching (the monitors are slower to respond than the KVM).
- The DVI is DVI-I, so you can connect two VGA monitors even if your computer(s) have one VGA and one DVI(-I).
- Handles high enough resolution for two 24" 1920x1200 monitors.
- The case is bomb-proof! Seriously, it's like 16-gauge steel.
- When I did have a specific non-functionality issue, the company was pretty good about taking care of it.

Cons: - When it does crash (which is rare - thankfully), the port placement makes it really tough to recover. The KVM apparently pulls power from either the DC plug or from any of the USB computer connections, so pulling the AC wall wart or DC plug doesn't shut it off. The USB connections are below the heavy, tightly spaced video connections (which also cause this KVM to want to tilt up onto it's back), so it's no small feat to pull and replace them all without some swearing.
- I had to resort to VGA connections (via a DVI-I to VGA adaptor) because the DVI connected monitor would often not wake back up when it had gone into powersave connecting the monitor directly back to the computer was the only way to recover.
- There is some pretty bad ghosting on the displays. I've learned to live with it, but my colleagues can't look at it for more than a few minutes without getting a headache. I can't imagine someone in any sort of graphics profession being able to function with this.

Other Thoughts: It is the best (non server/rackmount) KVM I've used, but I'm sure there must be a better one out there, or that someone could make one like this but without its limitations. Because of the ghosting problem, I'm not totally convinced this KVM is worth the high cost, but after cajoling my workplace to purchase it, I am not in a position to ask to try another option.

2 out of 5 eggsFun Whil eit lasted

Pros: Functioned as designed... for a while.

Cons: We currently have five of these in our lab. They are about 18 months old and get daily use. At about 12 months the USB ports would suddenly stop working... and that means no key board or mouse. You have disconnect the power and all powered USB cables to reset the box. In the past two months two of the five have bricked completely. Only one is working without issue... oddly enough it was hooked up several months later than the other four. We are now shopping for new KVM switches... they won't be LINKSKEY.

Other Thoughts: If you don't mind spending that much money every 18-24 months this is the box for you.

4 out of 5 eggsPricey, but a perfect solution for me

Pros: Needed a dual-monitor KVM solution for 3 separate laptops. All 3 laptops had DVI & VGA out, and I was able to use this device as a solution. Works well right out of the box, simply follow the instruction to boot the PC's up one at a time and allow the drivers to load.

Cons: The only Con is the high price of the unit, but since Linkskey is they only company with a solution that fit my needs, I only took off one "egg" in my review.

Other Thoughts: There are USB KVM's, DVI KVM's, VGA KVM's, but this is the only dual-monitor USB KVM that supports DVI and(!) VGA. This is running on Windows 7 & XP in my instance.

3 out of 5 eggsquestion

Pros: read below

Cons: read below

Other Thoughts: The cables included say they are DVI-D but the device says the connectors are DVI-I , I guess its DVI-I (lower top resoluiton 1920x1200 shown in specs) but why included DVI-D cables? misprint or trying to fool some?
