4 out of 5 eggs Can cause frustration in Win7

Pros: Inexpensive for 8 ports, but not as cheap as it looks once you add 8 cables..

Quick & easy to set up.

I especially like that there are 15-foot cables available. No need to separately buy extender cables to connect to computers that are farther away.

I'm not in a rack-mount environment, but it fits nicely under my monitor.

Cons: This does not transmit constant monitor EDID. That's the signal that tells your computer what monitor type you have. Windows 7 (and I assume 8, I haven't gone there yet) contantly polls your monitor to see if you've disconnected it. Why? Who knows. Lots of people turn their monitors off or have KVM's and it should have no effect. Microsoft calls it a "feature". But it's not something you can turn off. If it's a "feature" it;'a a poorly thought-out one. With some display adapters and drivers in Win7 (maybe most, I have one that doesn't), the screen will re-size to the smallest available when the moniotor is not attached for some period of time. And with this KVM, the computer thinks the monitor is detached when you select another port. When you come back, any windows you left open are crammed in the upper left 1/4 of the screen (more or less, depending on monitor resolution). It's even worse in a dual-monitor configuration. I read of a work-around where you disconnect pin 12 of the monitor (where EDID comes in) and configure it as a non plug-n-play monitor. Haven't tried it. It's not a unique problem with Trendnet -- the internet is full of folks complaining since Win7 came out. But ones that don't do this cost more than twice as much, so I put up with it.

I have also seen the "dead mouse and keyboard" issue. It typically happens if I power cycle a computer while the KVM has that computer selected. If I switch away before it powers down and back while it's powering up (but early enough in the boot that it detects the monitor correctly), everything seems to be OK. When the problem does happen, you can unplug and re-plug the USB all you want, it'll do no good. It gets detected as an "unknown USB device". Only disconnecting and re-connecting power will fix it. Since having multiple machines connected seems to keep it powered up on it's own (at least for a long while), I have to disconnect everything to get power to cycle.

Bottom Line: When one port went dead on my 4-port Trendnet, I upgraded to 8 with this one.

Don't know which 4-port Trendnet KVM the other reviewer had, but my old cables work fine at least with the video and USB. Mine was a KT-423, which also has PS/2 capability at computer end. Haven't tried that since it's not a listed feature and I no longer need it.

1 out of 5 eggs All ports died after 9 months of use...

Pros: Very cheap considering how many ports there are. Slim and durable case construction.

Cons: All 5 of the 8 ports died in succession and within 5 minutes of each other after 6 months of use. It seems to me something internal shorted out. About 3 months later, three more died. So this leaves with an entirely useless KVM.

1 out of 5 eggs Aarrrgh!

Pros: Cheap (this might be a con)

Cons: Warning: does not come with cables to hook up a computer. Not Even One. This leads to....

Warning #2: Since I work in a corporate environment, I thought "well it is a good thing that I have a bunch of KVM cables for other devices lying around". Wrong. I can't make this work with any cable. Sure the monitor function works, but I can't get this to work with a mouse or keyboard on anything we have. Xp, Win 7, Server 2003, 2008 R2, 2012. Nothing responds to keyboard or mouse control. This is brand new out of the box.

Not pleased at all.

Manufacturer Responses:

Hi Anonymous, We are sorry for any misleading information that would've led you to believe that this unit shipped with cables. Our KVM cables have been optional and can be purchased using this link - .

1 out of 5 eggs Great if you don't need the keyboard

Pros: Monitor always works, mouse almost always works

Cons: Keyboard is totally unreliable

Bottom Line: I bought this because I had a four port mamma san KVM (that I bought for $30, including cables, at a computer show) and needed to work with more computers. The 4 port no name KVM would hose up every six months or so; turn it off and turn it on and every thing worked again. I am introducing a number of new computers to the office desktops. They are all from the same manufacturer (Dell) and are the same model and have the same amounts of memory. On the plus side the monitor has always worked, always. There have been few mouse failures, very few. But the keyboard is purely hit or miss. It will stop working in the middle of a session. It not work sometimes when you return from a session with another computer. The only reliable way to restore it is, get this, power off the KVM AND disconnect all the computers. Sometimes but not all the time if you reboot he lost computer it will come back. I even had a computer get so hosed that it was never again able to use any keyboard, i.e. even with a keyboard directly attached. I've never had that happen before, had to use handicap access on screen keyboard to reinstall the operating system. This was sufficiently weird I'll give Trendnet a pass on that even though it happened shortly after the computer was attached to the KVM.
So, if you only need to use a mouse, this might be the KVM for you. If you are fine with FREQUENTLY having to directly attach a keyboard to computers when one or more ports fail; or better yet directly attach an additional keyboard for every computer attached to the KVM, the this is the KVM for you. Personally, I think it is best suited to be a boat anchor.
By the way I am writing this with a directly attached keyboard because the Trendnet attached keyboard doesn't work (both are Dell keyboards).

Manufacturer Responses:

Hi Eddy, So sorry for any inconvenience this may have caused you. Please ensure to use TRENDnet’s cables with your KVM and see if they help on either PS/2 or USB or not. If it still doesn’t help please contact me directly at with “Newegg TK-803R R” in the subject line and I will respond immediately to assist. I am looking forward to hearing from you soon and to restoring your faith. Warmest regards, Adrian

2 out of 5 eggs Ports broken

Pros: Easy switching if computer will run on all USB cables

Cons: Purchased on 6/22/12. 2 ports are not functioning on 6/26/13 just 4 days after warranty has ended. Cables and computers work on the other 6 ports but not on the 2 that do not respond.

5 out of 5 eggs Great Value

Pros: A few issues with mouse/keyboard in BIOS/DOS environments.
SeaTools in UBCD will not recognize mouse, but keyboard works. Of course, DOS doesn't officially support USB, so I can't blame TrendNET.

Every so often (maybe once a week at a full-time computer refurbishing job) I'll have a port "go bad" where any computer you plug into it will never recognize and initialize the USB device. A quick power-cycle fixes things.

By far the cheapest 8-port USB KVM available anywhere, even including cable costs.

Cons: As mentioned above, slightly buggy, on occasion, but always easily remedied.

Bottom Line: Don't forget to order cables.

4 out of 5 eggs Nice

Pros: This is now in our server rack ... I bought it because I needed to get rid of the old PS2 KVM switch and get something that supported USB ... and for the price it's great.
There's no On-Screen-Display and no security options ... but if you don't need those two things this KVM is an excellent choice.

Cons: none
