    I'd like for one receiver, C61-700 to output simultaneously to two 4k tv's,. We have two seldom used bedrooms each containing a 4k TV. Can anyone recommend a reliable HDMI splitter preferably one input with two outputs?

    I don't remember the model, but I recall it been posted here.

    That may be overkill for what he needs. It handles two inputs and two outputs. He only needs one input, like this one at half the price:

    Monoprice Blackbird 4K Mini 1x2 HDMI Splitter, USB-Powered - Monoprice.com

    I will add a caveat, though. I've had several of these from different sources, including Monoprice, and they've all worked for at least a year but eventually stop working. Don't know the truth of this, but I've read that this is due to the cheap units copying HDCP certification from actual certified units, and that the old certification expires eventually.

    I gave up on the splitters years ago for that reason. Never had one that worked well and they never last. Passive devices are the worst, I would never buy one that doesn't come with a wall wart. This is not the kind of device you want to try to save money on. If you absolutely have to have one, I'd suggest buying an expensive one and hope for the best. No matter what I did, no matter how much I paid, they all failed. But, it's been years since I've tried one, maybe they're better now.

    Yes unfortunately the vast majority of HDMI splitters are cheapos made in China using forged HDCP keys. Two ways around that, one buy another cheapo splitter when yours stops working, or buy a brand name device for several times more that uses a legitimate key.

    I don't think there's any way to know which "brand names" are using legit keys though. Some could be cheapskates and relabeling cheapo splitters. I imagine if you go to a site like avsforum.com there are threads where people can recommend brand name splitters using legit keys that won't stop working in a year or two.

    FYI the reason they stop working is a firmware update from Directv - the HDMI org requires makers of compliant "source" devices like DVRs, set tops etc. to include updated key revocation lists when they produce firmware updates. So if you have a choice about installing firmware updates (like on your set top) or are using a really old device that no longer gets firmware updates (the case for quite a lot of cable TV equipment, perhaps before long Directv's H2x/HR2x) then the cheapo splitter will continue working for you.

    You can 'test' this yourself by checking a splitter that stops working on something that hasn't had a firmware update in a long time. If it "died" because of the key revocation, it will still work fine if you connect it to a different DVR or set top that hasn't had a firmware update that where the splitter's key was revoked. That's the case most of the time - failure from other causes should be pretty rare, especially when it is within only a year or two.

    Some of this may not apply for 4K capable devices, I'm not sure. HDCP 2.2 uses a new generation of HDCP tech and forging keys may not be possible. They could steal keys from other devices, but revoking those would be problematic so I'm not sure whether they'd do that. Probably couldn't hurt to take a chance on that 1x2 4K Blackbird and see what happens.

    The only time I've ever had a splitter fail was a crappy power supply. (I read that somewhere, and it turned out to be true many use those crappy power units.)

    Swapped out the PS and it's working ever since.

    I have yet to experience an HDCP failure but I'm sure that's possible too.

    Many models of HDMI splitters works fine without PS. Most of device's HDMI output port providing enough power [5VDC] to run the splitter [often using DC-DC to 3V inside ]

    I had so many splitters and none of them lasted. Never saw a bad power supply tho.

    I had a friend tell me yesterday about the Yamaha RX-V685 and it has dual 4K output ports on the back of the receiver. Very tempting to get. . Could be an easy solution with upgrading to 4K at the same time.

    Taken from the owners manual

    Dual HDMI Outputs: The receiver's two HDMI outputs are parallel, so the same HDMI audio/video signal is output through both and can be used simultaneously (video is output at the resolution supported by both TVs).

    Yes that would Very nice

    You want the same content going to two TVs? I can see that in a man cave but it becomes a bit of a PITA when used in separate rooms. I have done that but not recently.

    Well kicking around extending to my back porch. I would have no issue with the same video, it would be for sports watching party anyway.

    I used mine to send both to living room and seldom-used guest bedroom. Guestroom mostly used by me when sick and trying to keep from passing it on to the missus. Almost never really need both sets at once so when my 2nd splitter gave up the ghost, just replaced it with a switch.

    My objective is to provide DTV to two seldom used bedrooms.

    Wireless HDMI has not been really practical until recently because it demands so much bandwidth. It also uses high frequencies that don't pass well through walls (or people) so it isn't very reliable. You'd be much better off getting a wireless client since passing 6-10 Mbps for an MPEG4 HD stream is a lot easier than passing a couple gigabits for 720p or 1080i HDMI.
