We installed an HD flat screen tv in our new outdoor patio and I wanted to split the signal from our HD cable box in the house and share it outside so I didn't have to get another costly cable box. I had been trying to figure out what kind of cable would you want to install? Co-ax? An HDMI cable? And then in time that format will be old and you have to remove it and install a different type of cable. Plus it would look awful and make a mess drilling through stucco. Then I found this HD transmitter/receiver and was so pleased - it solved my problems! I ordered the more expensive version in case I want to have more than one source, but I probably should not have bothered with that as I don't think I will be hooking up a dvd player or computer or anything else. Since I wasn't sure, I decided to upgrade just in case. The directions are kind of long-winded, but once I got it in my head how to set it up, the actual installation was very easy. I have my inside tv connected to the transmitter via direct HDMI cable, and the wireless receiver is hooked up to the outdoor tv, also via HDMI cable. (Also have an A/C power cord for both the transmitter and the receiver, so you need a plug nearby for each. This one does not get power via USB cord, unless I'm missing something.) The receiver is very lightweight and easy to hang on the back of the tv. I connected the remote control extension cable to the receiver and stuck it on the front of the tv, so the receiver is out of sight but you can use the remotes aiming at the front of the tv. I connected the IR blaster cord to the transmitter and stuck it on the front of the cable box over the sensor that receives the remote control signal, and now I can take my cable box remote outside and aim it at the tv and it controls the cable box. Very nice! The signal is excellent - I do not see any degradation of quality. Of course, both inside and outside tvs have to show the same program. Only minor issues are that the tv inside now receives signal through the IOGear transmitter and that makes changing channels sometimes a bit slower. Also for some reason if I turn off the inside tv the outside tv loses signal, so I need to figure out why - it should not do that so I may have set something up wrong, but I don't mind that too much. The biggest issue is that I often have to unplug the power cord on the outdoor receiver to reset the receiver, otherwise it will not connect. But that is easy to do - unplug and plug power cord back in, and then it connects quickly. May be due to being outdoors, who knows. The transmitter is only about 3 feet away from the receiver on my setup, with a thick frame/stucco wall in between. Not sure how far the signal would travel through an exterior wall. Anyway, we LOVE this unit and being able to have great HD signal from our cable box outside! I've had it a week, so hopefully all will continue to be well for a long time. (I do have the tv and receiver completely covered with water repellent breathable fabric cover when not in use to protect them from dust and moisture, so that should help.)

Although some have had mixed reviews, this unit solved my problem. Short history, Family room remodel (moving tv over fireplace). I wanted no equipment in view so all the components were going into the laundry room (right next door). All is over a crawspace (inside, not outside), so instead of tearing up walls to run cables, went down, under, and up into the laundry room. Cable length is a bit over 30. I am sort of a neat/organizer freak and didn't want wires just coming out of the wall through a hole, so at each end, have quickport/keystone wall plates. I also ran TWO of everything behind the TV, 2 hdmi, 2 optical and 2 ethernet. Make a long story short, I had a signal length issue. Depending on the content or the device feeding the tv, I would have intermittant (or more) screen flashing. After several attempts (and purchases) of line boosters/amplifiers/distribution boxes the only solution that worked was 1 short redmere cable at the tv end and a 1' cable from the receiver to the wall in the laundry room. Then I upgraded my receiver and lost everything (newer equipment, cheaper components, less signal).

I started researching wireless hdmi systems as a last resort before cutting drywall and running a shorter more direct run. I decided on the iogear mainly because it sends uncompressed signal.

I was not sure this would work as advertised, so when unpacking I only unpacked each unit and each power supply (used my own hdmi cables, I have PLENTY). This thing worked like a charm. I 1st just sat it on the fireplace mantel to test for a day. I later have it now just sitting behind the tv (it's pretty small so it fits easily behind). I then mounted the transmitter unit on the wall in the laundry room. Been almost a week w/no issues.

The units do not get too hot (a complaint I read about some others). The other bonus is once I turn off all my equipment, I just leave these on (last thing I need is another unit to turn off). They power themselves off after a while. The best bonus is they power themselves BACK ON once I turn everything on. Quite the welcomed feature!

I cannot comment on anything else about these, I haven't even unpacked the remote or flashers. I already have IR repeater system installed, and all of my source switching is done via my A/V receiver. This thing is literally PLUG AND PLAY!

Wireless 5x2 HD Matrix
1. Q: My video is not showing up on my TV.
  1. Double check all connected power and HDMI cables for a secure connection. Restart power in the following order; Wireless 5x2 HD Matrix, TIVO and TV in that order and verify if a stable wireless connection is achieved.
  2. Try the Wireless Kit with the transmitter and receiver in the same room and verify if you are able to establish a connection. If a connection can be established, then reinstall the wireless unit back to its original closet location and proceed to step #1.

2. Q: Where should I place my wireless transmitter?
A: The transmitter can be placed anywhere within the home or same room as the receiver within 100’. The transmitter can function properly inside of many cabinets, but depending on the cabinet materials.
Please note:
  • Wireless signals are able to penetrate walls made of standard drywall/gypsum board with wood framing.
  • Concrete, brick, cinder block, steel and water (such as aquariums) may adversely affect, hinder or eliminate the wireless signal.

3. Q: Where should I place my wireless receiver?
A: For best results, the receiver should be positioned such that well ventilated.
Common places:
  • Wall mounted behind HDTV
  • Wall mounted below HDTV
  • Wall mounted above the HDTV
  • Wall mounted to side of HDTV
  • Placed on top of table or cabinet
  • Mount on ceiling near projector
The receiver should never be mounted directly behind the center of a TV or on top of a projector.
Please note:
  • Wireless signals are able to penetrate walls made of standard drywall/gypsum board with wood framing.
  • Concrete, brick, cinder block, steel and water (such as aquariums) may adversely affect, hinder or eliminate the wireless signal.

4. Q: Why does my HDTV turn off when I turn off my Blu-ray player?
A: This is due to HDMI-CEC (Consumer Electronics Control), a feature enabled on your TV and source device (blu-ray player). To disable the CEC feature from your source device settings, please see your source device user manual for directions.

5. Q: How do I use the IR blast cable?
A: The Receiver can also send RF signals to the Transmitter. This means that you do not have to point your remote control at your devices as you may be watching TV in a different location.
  1. Plug the IR blaster cable into the IR OUT port of the transmitter.
  2. Refer to your devices’ user manual and locate the IR sensor. Manually move the IR blaster to identify a good IR response position. Peel back the adhesive backing and securely place the IR blaster onto the device.
  3. When the connection is established, the Transmitter relays infrared commands from your Receiver to devices. You may need to change the IR frequency to meet your devices’ IR specifications. See Troubleshooting for details.
  4. Plug the IR blaster cable into the IR IN port of the Receiver.

6. Q: My DVR/Set-top box or Blu-ray/DVD IR remote isn’t working properly.
A: Press the IR button on the included remote to switch the IR Blaster frequency to meet media source device’s requirement (38KHz / 47KHz / 56KHz). Please refer to your device’s IR specifications.

7. Q: What is the IR button for on the remote?
A: Press the IR button on the included remote to switch the IR Blaster frequency to meet media source device’s requirement (38KHz / 47KHz / 56KHz). Please refer to your device’s IR specifications.

8. Q: How do I switch between my connected devices?
A: With the included IR remote, press the SOURCE Selection button to switch media source of the transmitter. You may also press the SOURCE button on the transmitter or receiver to switch manually.

9. Q: Why does my TV flash when turning off or on the other TV?
A: This only happens if both transmitter and receiver are watching the same source and one side changes to a different source or if both transmitter and receiver choose the same source. The screen will refresh making sure you receive the most optimal resolution for your HDTVs. This is due to EDID (Extended Display Identification Data) - the data provided by digital displays to indicate their capabilities to video sources. The Wireless 5x2 HD Matrix distributes HDMI signals from your video source to two HDMI displays. In order to deliver the best audio and video formats supported by both TVs, the kit reads the EDID information from both displays and determines the "Best Common" video resolutions and audio format to send to the video source to program EDID on the device (i.e. Blu-ray player’s auto resolution setting) In order to output the best common resolution, the kit reads the EDID whenever a TV is plugged in, unplugged, or turned on/off. You will see both TVs flash couple seconds in order to adjust the "Best Common" resolution that all devices can handle. To get the best resolution for a specific TV (i.e. 1080p 3D), you can manually change the resolution from your video source or unplug the lower EDID devices then power cycle the kit and devices. For certain 3D Blu-ray players, you may need to eject and insert the 3D Blu-ray disc. Since your video source is not outputting the best common resolution, one of your TVs may not show any content or play audio only. Please refer to your devices’ user manuals for further instructions.

10. Q: What is the difference between wireless 5 GHz, Wi-Fi with compression and 60Ghz AV solutions?
A: 5GHz Uncompressed: Operates on the 5GHz band "based on WHDI™ technology" designed to provide a high-quality, uncompressed wireless link which can support delivery of equivalent video data rates of up to 3Gbps (including uncompressed 1080p) in a 40MHz channel in the 5GHz unlicensed band, conforming to FCC regulations. Range is beyond 100 feet, through walls, and latency is less than one millisecond (<1ms).

It provides consistent picture quality with low latency (<1ms) and low power consumption.

Wi-Fi with Compression: Operates on Wi-Fi within 5 GHz (802.11n) technology to transmit video between data rates of 400 to 600Mbps. Wi-Fi must therefore rely on video compression technology. Compression codecs are typically used (H.264, MJPEG, etc…) to compress and decompress (encode/decode) the A/V signal in order to fit High Definition video (1080p) through its limited bandwidth. Range is 100 feet, through walls*, and latency is less than thirty milliseconds (<30ms).

Video compression technologies are key and may inadvertently degrade video / image quality and introduce greater latency (<30ms). Compression technology utilizes more power consumption to process which can generate additional heat to which video pixilation and loss of signal may occur.

60 GHz: Operates within 60 GHz band and requires line of sight between transmitter and receiver. The range for products will be in-room, point-to-point, and line-of-sight at up to 10 meters which is 30 feet. A technology which provides up to 4 Gbps of bandwidth, more than enough to transmit uncompressed 1080p Full HD video - providing wired-equivalent image quality and latency.
