Full Review - Testing and Conclusion
Setup and Use Setting up the HM-31 is quick and easy. Connect your HDTV to the HM-31 by running an HDMI cable between one of your HDTV's HDMI inputs to the HM-31's HDMI output port. Connect your components (DVD plater, cable box, Apple TV, XBOX, etc.) directly into the HM-31's three HDMI input ports. Connect the power adapter to a wall outlet and the DC end into the HM-31 power jack. The HM-31 will instantly turn on and will be ready to switch HDMI sources. Turn on your TV and select the HDMI input that the HM-31 is connected to. With all your components turned on, one of the three HDMI sources will be on the screen of your HDTV. Use the HM-31 remote or the button on the front of the HM-31 to cycle through the three HDMI sources. Conclusion
Note that when you use the HM-31 remote, the HM-31 needs to be in sight of the remote. The remote is infrared and will not go through components or walls. If you want to keep the HM-31 out of sight, you can do so by connecting an RS-232C remote adapter or an IR remote extender.
Once your components are connected and turned on, the HM-31 will show red lights on the front panel This is normal. A red light means that an HDMI signal is ready on that port. A blue light means that an HDMI signal is active and that particular HMDI source has been selected. Blinking blue means that a port/source has been selected but that no signal is detected by the HM-31.
When using the HM-31 for DVDs and HD-DVDs, the signal, picture and sound quality were all stunning. The picture from Apple TV, XBOX and PS3 is equally gorgeous. So long as the original file or audio/video signal is high quality, the HM-31 will bring that image across with no noticeable loss whatsoever. The source-to-display ratio is constant.
The OPPO HM-31 HDMI switch is a great little device for adding more HDMI devices than your HDTV can natively handle. The HM-31 is easy to use, takes up very little space and comes with a compact little remote. The HM-31 does one thing - and does it well. The $99 price point is the only factor that raised a few eyebrows. Other quality HDMI switches are available for less. If you're familiar with OPPO, however, you'll know that their products are high quality and usually worth the extra few dollars.
Pros:
• Compact, high quality HDMI switch
• Very easy to set up and use
• Excellent audio/video quality
• Supports 720p, 1080i, 1080p, etc.
Cons:
• High $99 price
• Limited to 3 HDMI outputs

“This unit will also auto switch between inputs based on a couple of factors... Since some units output an HDMI signal even when they are turned off, or are devices that you want to leave on at all times, like a DVR, you can use that info along with...” More...
