Pros 1.3 Certified, Connects Blu-Ray, HD-DVD thru A/V Receiver
Cons Only 3 inputs
Summary Bought the Monoprice 5x1 switcher and tried to connect my Sharp Blu Ray, Toshiba HD-Dvd, and a Onkyo Up-convert Dvd thru the switch to one of the inputs on my Onkyo Receiver with 2 HDMI inputs, 1 output. No Dice, the monoprice unit didn't give me a screen on either of the High Definition units, it did pass the signal from the Up-Convert DVD unit, but that's not what I was looking for. Evidently the problem is that the Monoprice unit is not 1.3 HDMI cerified. Not the case with the OPPO HM-31 Switch. Plugged in all units, sent the signal thru to the input on the A/V Unit and viola! HD Heaven. The unit worked like a charm and it is 1.3 certified, so if only 3 inputs is not a problem for you and you have HD-DVD and Blu-ray players, then this Switch is perfect. I gave it a 9 because so far I haven't heard of any problems with the unit on any other review pages, while the same cannot be said of the units without 1.3 certification.
Pros signal conditioning, and autoswitching
Cons none outside of the price...
Summary This switch prioritizes the input ports from 1 to 2 to 3. If you put your always-on component (mine is a Tivo HD) to port 3, and your other components to ports 1 and 2, then your HDMI signals pass to your A/V receiver in priority order. Just turn off your other components when you want to watch your Tivo (or other DVR) and the HM-31 auto-switches to port 3. Want to watch a DVD player connected to port 1? Turn it on and the HM-31 switches to port 1 as it has a higher priority than 3. How about your other component on port 2? Turn off component on port 1, and turn on the component on port 2, voila, the HM-31 switches to that port as it is still higher than port 3.
Only hitch happens when a component sends a signal out of its HDMI port even when it is turned off, but you still have the remote to handle those hardware situations.
The HM-31 displays one of three light colors depending on what it senses on any port.
It displays nothing if it senses no signal on the incoming port.
It displays a red light if it senses a signal is present on a port.
It displays a blue light if it senses a signal and is sending that signal through to the output HDMI port. It will blink with a blue light when it can't find any incoming signal, but has been artificially directed to switch that specific port to the HDMI-Out port.
The blinking light will only happen when you use the remote or the button on the HM-31 to direct output from that inactive port to the HDMI-Out port.
For what it is worth on signal conditioning, I found a "white paper" on the Oppo site that describes their switch receiving a signal on an incoming HDMI 1.3 rated cable 50 ft. in length and passing that signal through another 50 ft. 1.3 rated HDMI cable to an HDTV with no signal degradation. It was tested at an an official HDMI.org authorized test center. I can't attest to that as I don't have cables that long but it might be of help to other readers.
"Great Switcher!"on by m007368
Pros 1) Worked out of the box. 2) No compatibility issues 3) Defaults to active signal if none present.
Cons 1) could have used one more port, but not an issue for me.
Summary I loved this device based on the sale price on Ama$#@ and it met all my needs with no hassle. I am using it only for video pass through and I am running all my sound via Toslink due to my YSP-1100 not possessing HDMI.
I have the following for reference routed through it:
DISH Vip 622 HD DVR
all routed to
Mitsubishi WD-52528 DLP
In the end the HDMI three ports wont be an issue since the next time I upgrade my YSP to the YSP-4000 there will be suffient 1.3 HDMI ports I wont need a switcher.
But this is an awesome intermediate solution.
Pros Works with any device I connected to it, true FullHD Video AND Audio 1080p
Autoswitching and signal conditioning
Cons only 3 ports
Summary I am very happy with the Oppo HM-31 HDMI switch, even if initially I thought it wass to expensive compared to others, like Monoprice switches. I have tested my devices with two Monoprice (5x1 and 4x1) and one IOgear 4x1 HDMI switches and the ones with 1080p video output AND Dolby TrueHD or Master DTS audio have not worked with them.
With the Oppo HM-31, anything I have connected just works. I also like the autoswitching function, as in my home setup it works fine without the need to use the Oppo IR remote to change the inputs.
The latest device to be powered on activates the input on th Oppo switch. When you power off the device, the Oppo HDMI input switches to the other powered HDMI input, if any.
In my case, the only device that powers the HDMI input on the Oppo switch even in standby is an Asus O!Play Air media player.
Excellent HDMI switch and excellent value for money!
Pros Nice small box design and easy set up make this awesome! You can tell Oppo takes pride in their product with the packaging and care they took making this product. I have tried 4 other swithcers and this one is the best! Beats Xtrememac and Terk
Cons Pricey an only 3 outlets makes it a bit out of budget. No power off switch on this thing make it a bit strange.
Summary Sleek design and solid controls and features make this a hit out of the park. Took 5 minutes to set up and even configured with my Logitech remote..awesome...
