The Atlona AT-HD4-V42 4x2 HDMI Switch provides a way for users to expand the number of HDMI-equipped components that can be connected to one HDTV. With an expanding choice of components begging for an HDMI connection, it is something many of us need.

If you have ever wanted to connect two HDTVs or an HDTV and video projector simultaneously, this switch lets you use two HDMI outputs to do that. The switch comes with an AC adapter and wireless remote that makes it easy to install and use.

The switch maintained its signal strength. The drawback is that it could use one or two additional HDMI inputs for added flexibility

Detailed Review of the Atlona AT-HD4-V42 4x2 HDMI Switch

I used a total of three HDMI sources for this review: OPPO BDP-93 Blu-ray Disc PlayerOPPO DV-980HD Upscaling DVD player, and a Samsung DTB-H260F HDTV Tuner. Using a variety of HDMI cable lengths (3 feet to 15 feet), I found that both the HDMI handshake and signal integrity was not an issue. When comparing direct connection of the HDMI components to the HDTVs used (Westinghouse LVM-37w3 1080p LCD Monitor and Samsung LN-R238W 720p LCD TV) vs HDMI signals going through the switch before going to the HDTV, the switch did not introduce any visible artifacts or changes in the source signal quality. In addition to video, there was the switch did not have any problem passing all the available surround sound formats, as well as 2 and multi-channel PCM audio signals.

I confirmed that the Atlona AT-HD4-V42 passes 3D signals using the OPPO BDP-93 as the source and an Optoma HD33 (on review loan) 3D DLP video projector.

In addition to direct-to-TV or video projector connection, I connected the source components to an Onkyo TX-SR705 Home Theater receiver then routed the HDMI output of the receiver to an HDMI input on the switcher, then to the TV. I also connected the source components first to the switcher, then to receiver, and the receiver to the TV. In both cases that there were no handshake issues between the receiver, switcher, or TV. The only handshake issue I had was when using the Optoma video projector - I got better handshake results when turning on the Blu-ray Disc player and the Atlona switcher before turning on the projector.

Here is a close-up look at the rear panel of the Atlona AT-HD4-V42 4x2 HDMI Switch. As you can see, everything is clearly labeled. Starting on the left is an RS-232 port (enables the switcher to be controlled by Laptop or Desktop PC, and just to the right, two digital coaxial audio outputs.

To access audio from the digital coaxial outputs, you need to use a TV with Audio Return Channel (ARC) capability. Here is how this works with Atlona AT-HD4-V42:

1. Connect your HDMI source to an ARC compatible TV.

2. Connect the HDMI output connection on the Atlona to the ARC HDMI input on the TV.

3. The audio signal travels back through the HDMI connection from the TV to the Atlona.

4. The ARC audio feed is then available via the digital coax outputs.

Using this feature you can send the ARC signals via the digital coax outputs to a home theater receiver that is either not ARC-equipped or does not have HDMI inputs.

Below the RS-232 and digital coaxial audio outputs are an IR in port, two Ethernet ports, two HDMI outputs, the four HDMI inputs, and an AC Adapter connection.

It is important to note that the HDMI outputs are mirrored, but the digital coaxial and ethernet outputs are independent for each display. In other words, once an HDMI input is selected, the HDMI signals are output by both HDMI outputs simultaneously. In addition, if desired, any ethernet or compatible audio signals originating from each display can be accessed via the Ethernet and digital coaxial audio outputs.

Final Take

Atlona AT-HD4-V42 4x2 HDMI Switch can be a great addition to your home theater setup, especially if you have run out of HDMI connections on your TV. The AT-HD4-V42 allows the user to connect up to four HDMI sources (Blu-ray Disc Player, DVD Player, HD Cable/Satellite Box, etc...) and send the output signal (either 2D or 3D) to two different TVs, TV and video projector, or TV and home theater receiver simultaneously. This switch also has extra flexibility for Audio Return Channel-equipped TVs.

The Atlona AT-HD4-V42 is easy to setup and use and maintains signal strength. However, the AT-HD4-V42 could use one or two additional HDMI inputs for added flexibility.
