1 out of 5 eggsWish it worked for me...

Pros: HDMI KVM for cheap.. Came with cables.

Cons: Does not work with ANY (5 monitors total - 4 different models from 3 different vendors - tested on 2 different laptops, 2 different desktops) of my monitors,,, However, it does work with my TV, which doesn't work for me and is not why it was purchased. What makes me more upset is that my system(s) show it as an active connection, including the proper model number and vendor description.. Not sure what makes my TV so much different.

Other Thoughts: I really wish this thing worked.. price is very reasonable and installation/connection was simple.

3 out of 5 eggs

Pros: Cheap and relatively small as a KVM box.

Cons: After using this unit for over a month, it's starting to get flaky, as one other reviewer pointed out. It'll skip over some of the ports when switching with the button on front. The only way to get it back operating normally is to pull all of the USB cables, from where it's drawing power, and then plug them back in.

3 out of 5 eggsFrustrating setup

Pros: Going from analog VGA to HDMI is a noticeable difference in quality. Comes with 4 combo HDMI+USB cables for PC's. Comes with power adapter (which is unneeded unless connecting high power USB devices on the front, such as a backlit keyboard). KVM runs off of USB power from PC's for switching. I am able to connect a wireless logitech mouse receiver and non-backlit USB keyboard without needing to use the power adapter.

Cons: 1. I have never had such a difficult time getting a KVM to work. I finally resorted to the manual and following the instructions explicitly. Mouse and keyboard were working but no video was displaying. I had to turn everything off, set the KVM to the first computer, boot fully, switch to next computer, boot fully, etc. I can only imagine what happens if I get a power failure or turn off all the computers and have to repeat this annoying process.
2. Does not come with HDMI cable from KVM to monitor.
3. Instructions are terrible. I had no sound until figuring out to press the sound button on the front of the KVM to get it off of headphones.
4. I thought going to HDMI would reduce the desktop clutter of the big VGA cables. It doesn't because the included cables are extremely thick and stiff. However, any USB and HDMI cable could be used, not just a proprietary cable like most KVM's. So either longer, shorter, thinner, etc. cables could be purchased and used.
4. Switching appears to be by remote or button only. The BYTECC website indicates this KVM will switch with caps lock + caps lock + number key of the device (1 to 4). This is false. It does not switch off of keyboard as BYTECC claims. Interestingly, Newegg states the 2-port model of this device can be switched by hotkey. For this 4-port model, that is missing from the item description despite the fact it's on the Bytecc website. However, don't get your hopes up. Keyboard switching does not work.

Other Thoughts: Try to find a 4 port HDMI KVM at this price. Everything else is nearly double, or more. But those devices may work a little better.

3 out of 5 eggsQuality Construction But...

Pros: Four Port HDMI KVM with extra USB to share a USB device other than a keyboard or mouse.
IR Remote control
Cheap, and includes cables
Quality metal construction, (Built like a tank)
When the audio device is turned on it converts the audio carried on the HDMI signal to a two channel signal for your headphones.

Cons: Questionable circuitry. This KVM does not always sync up when you switch it from one computer to the next. Frequently your monitor will detect that there is something connected but will say no signal. However after rotating through the 4 PC's a few times it will pick up the one that was getting a reading of no signal from. This is when the computers are awake. occasionally Ill switch to a PC and the monitor will show snow like in the good ol' days of analog sky-wave. Switching away from it and back to it will usually fix that issue. Additionally switching is relatively slow about 4 to 7 seconds. I know that may not sound slow to many of you but as a comparison my previous D-SUB KVM switched in less than 1 second just press scroll lock twice and you are almost instantly switched. In addition to that; this KVM as far as I know does not have a hot key for switching just the button on the switch or the IR remote.

Other Thoughts: While this switch may have a few annoyances I can live with it rather than pay an extra $100 or more for a switch that also has issues people have complained about. If your looking to save energy this switch only uses 4 watts as measured by Kill-A-Watt when a computer is active and 1 watt or less when all computers are asleep or just not selected. I would recommend it only because there is not a better one even close to this price. However if you are using it in a business environment I would say spring the extra money and get one that is more reliable.

5 out of 5 eggsWorks great on my system

Pros: Supports HDMI and USB
Comes with cables
Comes with a remote

Cons: Doesn't have a way to automatically skip a port or directly select a port on the box
Doesn't always reconnect the keyboard (have to unplug and replug occasionally)
It's no longer available!

Other Thoughts: This is the only unit of its type that I could find for under $200. It works great for my environment (3 computers). The sad thing is that it's not currently available - I hope they come out with a new model in case I need another one.

2 out of 5 eggsYou get what you pay for

Pros: 4 inputs, 4 cables combine HDMI and USB, convenient remote.

When it works it works.

Cons: Will often lose video synchronization with computers, requiring "in the dark" reboot to get video synchronization again. This is the worst problem, and it happens unpredictably. This is with Linux and Win 7 boxes each with GeForce 210 cards.

Does not allow O/S to put monitor to sleep; it keeps monitor seeking missing video input when the computer suspends the monitors.

Other Thoughts: I have had more expensive solutions with their own issues. With these KVM switches, there seems to always be something to deal with. But this one has 2 strikes against it, immediately, out of the box.

5 out of 5 eggsI'm impressed!

Pros: 1. Price. I shopped around the web for an HDMI 4- to 8-port KVM, and the cheapest I found before this was about $150. I almost got one of those more expensive ones, but luckily found this one before wasting money.
2. It works like it's supposed to, and it's fast! I'd say, after pressing the button to switch sources, within 3 seconds it's on the screen and the keyboard/mouse are active.
3. Came with 4 HDMI/USB cables! Wow...no scrambling for HDMI cables or USB cables for my computers. The USB is integrated into the HDMI cable and works perfectly and less cable mess.
4. Comes with a remote. Mine is right on my desk...resting under my 24" LCD TV actually. I can reach it just fine to switch but the remote works flawlessly as well.
5. Nice metal casing. Does not feel cheap at all. Strong and big enough to rest my LCD on (just a little overhang of the LCD base but sturdy and stable). Cables are good quality too.
6. When my computers are powered on and connected, they don't get disconnected from the switch when I changed sources to another PC. That means that once I set up the displays (duplicate or extended), I don't get any constant refreshing of the screen when I'm switching back and forth between PC's. No icons getting moved around. They obviously retain the connection to an outside monitor even though it's not active for that PC. This obviously adds to the speed of the switch and is much less annoying having your screens refreshing.

Cons: USB inputs for shared keyboard and mouse are in the front. I'd prefer them in the back since that's where my cables come from.
So far I can't think of any other cons...

Other Thoughts: I needed a 4 or 8-port KVM for my home desk since I have a work laptop, 2 personal laptops, and a Windows 8 Tablet that I wanted to share all with one monitor, and inputs.
My tablet dock and 2 personal laptops are connected directly via HDMI with the included cables. Video and sound are coming through perfectly.
My work laptop dock is connected via DVI and DVI-to-HDMI adapter. Obviously no sound, but the duplicated screen onto my LCD TV monitor is perfect and maintains its screen resolution of 1366x768 without refreshing or flicker.
I haven't used the shared USB port or the shared headphone or microphone jacks either. So I can't comment about those yet.
But this switch is WELL worth the money for it (my standard of reviewing a product). Cheapest I found, and works flawlessly so far.
