Anyone here use HDMI?

In my current set up, my AV closet is positioned behind my main seating area. With my ceiling mounted projector about ten feet away, I'm lucky to have a grid ceiling. Otherwise, running a HDMI cable to the projector could be problematic.

For those who aren't as lucky, Adrienne Maxwell might have a solution to that very problem.

Here's part of Adrienne's review on

The Air wireless products are based on the WirelessHD standard, which operates over the 60GHz band and allows for the transmission of 1080p/60 video (with 3D support) and eight-channel high-resolution audio (up to 192 kHz). The 60GHz band isn't as crowded at the 2.4- and 5-GHz wireless bands, which cuts down on potential interference. WirelessHD claims "near zero" lag time, making it suitable for gaming applications. WirelessHD is an in-room solution, meaning it's not designed to transmit signals around your home, through walls. Rather, it's ideally suited for sending signals across one room--for instance, from your source device or AV receiver to your projector or TV.

The Air3C-Pro package includes a transmitter unit (DVDOG3T-PRO) and receiver unit (DVDOG3R-PRO), each of which measures roughly 4 x 3.5 x 1 inches and weighs about five ounces. The transmitter unit has one HDMI 1.4 input and one USB port, while the receiver has one HDMI 1.4 output and one USB power port. These units omit the MHL support found in the Air 3, but both the transmitter and receiver units can be powered via USB, so you don't need a power outlet nearby if your AV gear has powered USB ports. I was able to power the devices directly from Epson and BenQ projectors, a Samsung UHD TV, a Harman/Kardon receiver, and a Dish Hopper DVR. The Air3C-Pro kit comes with two HDMI cables, AC power plugs, and wall/ceiling mounts to affix the tiny units to the area around the gear or to the gear itself.

In-room wireless HD solutions often require line of sight between the transmitter and receiver; the simple act of walking in between the two devices could disrupt the signal, and past products have been painstakingly slow to establish the HDMI handshake and produce a picture on your screen. Neither of those issues presented itself here. The DVDO system can bounce the signal off of walls and ceilings, allowing the transmitter and receiver to be tucked away in more discreet locations. No, you can't place them in an enclosed cabinet or another room, but you do have a little more freedom to place them out of sight. Also, the RF-based "beam steering technology" automatically scans the room (up to 60 times per second) and looks for the best path from transmitter to receiver to ensure a reliable connection. The maximum recommended distance between transmitter and receiver is 100 feet if they have line of sight and 35 feet if they don't.


High Points
• The DVDO Air3C provides a very reliable in-room wireless HD solution--ideal for sending your HDMIsignal from your AV components to your display.
• I did not see any resolution loss in test patterns when comparing a direct, wired HDMI signal with the wireless DVDO signal.
• DVDO's RF technology bounces signals off walls and ceilings, so you don't need perfect line of sight between transmitter and receiver.
• You can power both the transmitter and receiver through your AV gear's powered USB ports, and mounting hardware is available to easily wall- or ceiling-mount these tiny devices.
• The Air3C-Pro version has helpful tools for a more advanced installation. Firmware updates are easier through the software, the signal strength indicator helps a lot to find the best placement, and you can change the pairing mode if needed.

Low Points

• The transmitter has only one HDMI input, so you need to run everything through an AV receiver orHDMI switcher to connect multiple sources. It also lacks an HDMI output to pass the signal through to a local display, which is good for situations where someone uses both a projector and an HDTV.
• The system supports resolutions up to 1080p/60, but not Ultra HD.
• The Air3C system doesn't let you use multiple receivers with a single transmitter (or vice versa) simultaneously.
• The supplied USB power cords are very short. So, if your AV gear lacks powered USB ports and you need to connect these products to power outlets, you will need to purchase longer cords.
