4X4 True Matrix HDMI® Powered Switch with Remote Control (Rev. 3.0)
If you're like most people, you have your home theater setup in one room, but have TVs in other rooms as well. This gives everyone in the house the ability to watch what they want, when they want. But what if the kids want to watch a DVD while you want to watch the big game in the living room with your friends? You can lug the DVD player to the other room for the kids, but a better solution is to use an this 4x4 True Matrix HDMI® Switch from Monoprice!
With this switch you don't need to move equipment from room-to-room, nor do you have to buy duplicate equipment for the other rooms in your home. This matrix provides 4 HDMI inputs, which allows you to connect the Xbox 360™, cable box, blu-ray player, and the output from your Android phone. Any of these four inputs can be independently selected for either of the four outputs. Each display can select the same or different inputs.
The switch includes a remote control, allowing direct selection of any of the inputs for each of the four outputs. Additionally, the matrix can be controlled by a computer, via an RS232 serial port, as well as front panel controls.
The matrix supports the full High Speed 1080p@60Hz HDMI video resolution and features a 6.75Gbps bandwidth, sufficient to support 3D video, 36-bit Deep Color, x.v.Color™, and high-definition multichannel audio, including Dolby TrueHD™ and DTS-HD Master Audio™. It is powered by an included 5 VDC, 2A AC adapter. The four input and four output HDMI ports are gold plated to ensure smooth, corrosion-free connections. It measures about 11" x 5.8" x 1.5".
Note: Monoprice strongly recommends using 22AWG, 24AWG, or active HDMI cables with Redmere technology to achieve the best results and to ensure minimum signal loss over longer distances.

Here are the 232 commands, working and tested. A regular null modem cable works (you can get at most electronic stores) female DB-9 on both ends. Baud is 9600, N, 8, 1
commands are simple (same as the commands for the 4x2 model) "X, NOT(X), d5, 7b"
X just goes from 0 to F as as you see below...
NOT is the byte opposite. So in hex, NOT(00) is FF
4 characters total (hex for all)
output 1: input 1 "00,ff,d5,7b"
input 2 "01,fe,d5,7b"
input 3 "02,fd,d5,7b"
input 4 "03,fc,d5,7b"
output2: input 1 "04,fb,d5,7b"
input 2 "05,fa,d5,7b"
input 3 "06,f9,d5,7b"
input 4 "07,f8,d5,7b"
output3: input 1 "08,f7,d5,7b"
input 2 "09,f6,d5,7b"
input 3 "0a,f5,d5,7b"
input 4 "0b,f4,d5,7b"
output4: input 1 "0c,f3,d5,7b"
input 2 "0d,f2,d5,7b"
input 3 "0e,f1,d5,7b"
input 4 "0f,f0,d5,7b"
**note, a regular null modem cable will NOT work with the computer software they provide, as the pinout of the cable they recommend is unusual and different. null modem cable works fine for home automation 232 control however. if you like, you can create a custom cable for the computer controlled software to work. this cable is pins 1-9 all straight through, except for pins 2 and 3 which are crossed. this custom cable will do both the 232 hom automation control, and their software.

Important features this switch lacks:
No manual EDID management. A switch with manual EDID management lets you manually tell your source devices what the least common denominator of your displays is, for both audio and video. Why is this important? For several reasons. Say you have one TV that accepts Dolby Digital audio, but all your other TVS only will handle LPCM. With manual EDID management, you can manually send an EDID that forces all your sources to LPCM audio. This ensures the sources are sending signals that can be switched in a matrix scenario to all your displays. Another reason for manual EDID management is it makes switching sources faster, as the sources never know that anything has changed with the display. The source thinks the display is always connected. An alternative to manual EDID management would be for the switch to intelligently provide an "intersection" of all the EDIDs from your displays, and provide this least common denominator EDID to your sources. This switch does not even do this well. So, if your displays support different audio and resolutions, you will have problems with black screens and no audio.
No signal equalization/amplification. As I mentioned, HDMI does not handle weak signals well. This switch does not equalize or amplify the HDMI signal before it distributes it. So it basically is outputting weak HDMI signals. Depending on your cabling solution, you may or may not have issues with these weak signals. This is why it doesn't work with HDMI extenders over CAT5, because they also will weaken the signal further.
So will this switch work for me? Maybe. If you are:
- NOT using HDMI over CAT5 extenders
- All of your displays have the same audio/video capabilities
- Do not have extremely long cable runs
then it will probably work ok. It didn't work in my particular setup. I ended up buying a much more expensive switch that has the features this switch lacks and it solved every single issue I was having. I'm disappointed that Monoprice does not mention anything about how this switch handles (or does not handle) EDID in the item description. This is an important aspect of HDMI switching that the purchaser should understand up front. I had to figure out this on my own so I'm not happy with the purchase of this switch.
PROS: Metal chassis, inexpensive.
CONS: No manual EDID management, puts out weak HDMI signals.
In isolation, the extenders (PID 8201) worked great. As soon as you introduce this matrix switch, most would fail to keep a signal on the remote TV. Colors would blink out, lines would appear, audio would drop, etc. I had two of these switches for my master plan, so I was able to try them both. Same result. I had even used power adapters at both ends of the HDMI extenders, and that didn't help. I can plug in a cheap 1x2 HDMI splitter (I mean really cheap) and it handles the extenders just fine. This Matrix just did not want to work at all.
Monoprice tech support said "these switches are not rated to work with those extenders". Of course, this isn't printed anywhere. They suggested I use a different matrix that comes bundled with extenders, but those extenders require a separate receiver box that is ugly compared to the clean in-wall install of the 8201 product. Too late for me to return $200 of extenders that won't do what I want, but at least I can get store credit for the two matrix boxes.
I would strong advise that you do not count on this switch working with an extender. If it does, good for you. It appears they are just too flaky to rely on.
PROS: Nice look. Solid construction.
CONS: Does not appear to consistently work with any HDMI over CAT5e/6 Extenders.

I'm controlling the matrix switcher with an mrf350 and every room has a mx850.
I have used 4 rooms at once switching sources around to see if the switcher would blackout a room or do something indicating a problem but this $156 switcher worked GREAT. The only thing is i wish i bought it a long time ago.
PROS: Cannot beat the price. Works great.
Flawless audio/video. No flickering, or hesitation. RS232 control.
CONS: No complaints from me at this point. So far 100% satisfied.
Any cons would be nit picking. I got what i expected plus some:)
HDMI Input 2 gets a Blu-ray player.
HDMI Input 3 gets a Roku player.
Outputs A,B,C, and D are connected to four 7.1 channel receivers, which in turn feed various TVs.
If outputs A, B, and C all select Input 2 (the Blu-ray player), output D cannot select Input 3 (the Roku player). The swapped input selection is also true (if A,B, and C are watching the Roku, output D cannot watch the Blu-ray player). I did not have time to analyze all the blocked paths in this switch, but there are more that exist.
In my case above, I was able to find a working non-blocked configuration:
HDMI Input 1 gets the Blu-ray player.
HDMI Input 3 gets the Roku player.
In this case, inputs A,B,C and D can select either input independently.
This is pretty sneaky behavior, and it took me hours and hours of debug time to finally nail what was going on. Hence the low rating.
PROS: Inexpensive, easy to install, and multiple control options (IR, RS-232).
CONS: This switch is not have fully independent switching.
Also, for $3.42 more, get an extra remote because they're small, easy to misplace and if you have to buy another one later, depending on where you live, shipping will probably cost you more than the remote itself plus, I can use the remote in another room about 50' away with an infrared remote extender I hooked up for my extra Tivo remote, I can actually change inputs/outputs from there too.
PROS: Pros: 4 HDMI in 4 HDMI out, mix or match, just like it's supposed to do
CONS: Cons: None really: it would be nice if the remote worked from further away and at a greater angle, but no big deal it would be nice if the unit did not require AC power, but I doubt that's possible.

PROS: 4x4 for under $200. Awesome price.
Discrete IR codes for all possible source/input combinations.
Picture quality looks just as good as without it in the middle.
CONS: No discrete "Off" command. So you can't program your remote macro to turn the whole thing off for sure.
Either it, my extender, or Onkyo receiver had trouble communicating "off" state
I have 2 Direct TV DVR's, Denon AVR, Oppo 3D blu ray connected to multiple LG monitors (all 1080, one is 3D). I have the Denon as one of the inputs and one of the outputs (giving me the ability to route another 7 HDMI devices through this). Having the Denon on both input and output simplifies the handshaking when everything is turned on.
PROS: Works out of the box. Does what is supposed to do.
I am routing 3D signals via this switch.
Of course, before I plug all of my components in, I decided to test a few first. That way if something went wrong, it would be a minor issue and not trying to deal with a whole mess of problems.
For reference, I'm always using the Monoprice HDMI Over CAT5E / CAT6 Extender Wall Plate (8009).
Nice and simple, I hooked up my PS3 to the 4X4 and then fed the signal to a 26" Insignia LCD.
Or so I thought??? After about 5 seconds, I saw a "glitch" with the picture. Almost looked like an analogue drop out. I kept watching and saw a few more and then a "black screen" and then it came back on again...
I was HOPING that I wouldn't experience any HDCP handshake issues, but it looks like I did...
Understanding that the Insignia TV is a little older (2 years) I wanted to make sure the tv wasn't at fault. So I then hooked it up using a different 8009 to my 2 weeks old 55" Philips LCD.
Ditto. Same handshake issues... Black screen periodically and some flickers... Okay... Let's remove the 4X4 from the equation.
Hooked the PS3 into the 8009 to head directly to the 26" Insignia. Perfect, no issues. Tried the same thing to the 55" Philips... Perfect results! So there's something with the 4X4 matrix in the mix that's causing some distress.
So I decided to try a different output on the 4X4 to the 26" Insignia... And this time it worked! Flawlessly! Same PS3, same 26" lcd... had it hooked up for 20 minutes and no issues. No flicker. Just a different output on the 4X4.
I hooked up BOTH the 26" Insignia AND the 55" Philips to the outputs on the 4X4. BOTH the Insignia and the Philips showed the PS3 screen simultaneously and I cannot seem to change that (I have only tested a single input decide thus far).
Depending on the combination of outputs used on the 4X4, I either have issues, or I don't?
Ultimately, what bothers me is that I have handshake issues using a single input and a single output.
So I'm going to keep poking and prodding to see if I can figure anything more out. I'm really hoping I can resolve the issue as this device is going to be a significant piece of equipment in y setup. If it doesn't work, I may need to patch through my Patch Bay...
Input 1 to (55" Philips on B, 26" Insignia on D) = Both Displays work fine.
The remote seems to do nothing and neither do the two buttons on the front of the 4X4 (Can't recall exactly what they are as I sit in front of my computer).
So I'm at a loss.
My next step will be to add my digital HD cable box to the mix so I have multiple inputs... I'm also aware that it could be the order of sequence the devices are turned on... I have been careful, but will provide more thorough testing results when I have them.
I gave this unit a 5/10 currently because the integration has not been what I had hoped for.
And also? Can anyone confirm... When I turn on my Matrix. It powers ALL of the outputs. So for example. When I have a single input and two outputs. Both outputs receive the same HDMI signal... That seems to be how it works in my case. I thought I'd be able to have 2 of the 4 outputs "turned off" for example.
So for example, if the wife and I were watching.. let's say "Blood, guts and volience - the return of Steven Segal" on the Projects... I don't want the kids to be able to turn on their tv and have them watch what we're watching? Right now, it seems like any tv that gets turned on is being fed the PS3 signal from the 4X4?
Is that correct behavior?
PROS: - Inexpensive
- Great picture quality
CONS: - Very unpredictable
- User manual is useless
