C61 4K HDMI Power Output?

I have a 4K HDMI 1x2 splitter that depends on the HDMI connection for power. I have the two outputs connected to two HDMI inputs on my Vizio TV. The input on the splitter is connected to my C61-700 4K receiver. Before I connect to the C61 the two monitoring lights for output are brightly lit. When I connect the C61 the input lights but dimly. The two output lights also stay lit but change to dim. And I get no signal passthru. This tells me something is off on the C61. A setting perhaps? Any knowledge or experience with this?

I have no experience with this,
but,
have you tried using each side individually ( 1 HDMI connected to the TV ) and see what the results are there ?

I've never seen any but powered splitters ever recommended in these forums (for whatever that's worth).

Powered are the only kind I've ever used. But I have noticed a little with the indicator lights even before (one of the splitters) was plugged into power (suggesting at least some kind of current coming through one or more of the cables).

Worth a lot. We keep recommending that folks only use powered splitters so they don't have problems like these.

On my TV you can set the Picture settings for each Source. I am assuming he is doing that,
or, he is feeding 2 TVs.

I did it to simplify de-bugging of the issue. In reality, if I can get it to work the second output will go to a DVDO wireless transmitter that sends the HDMI stream to a 4K panel in an adjoining room. Which brings up a second problem. But I digress.

The HDMI spec only requires providing 55ma @ 5v for EDID. Some devices provide more power than that but it isn't required by the spec and can't be counted on. Any splitter that can be powered ONLY by the source port and doesn't have provision for an external supply should IMHO be returned and exchanged for one that does.

The splitter, a Monoprice Blackbird, has a power input but was sold without the transformer to price it low. I have to decide on whether to buy the transformer for about another $10 or scrap this one and buy a $41 one that has 18mps instead of 10.2 with EDID switches for setting the usage criteria.

One more time folks...buying an HDMI passive switch is just looking for trouble. Make sure you get a powered switch. That's one with a wall wart.

I agree with the above suggestion. Several years go while testing a new DTV box, I tried a non powered splitter and it wiped out the HDMI output. Apparently the DTV HDMI outputs just meet the industry spec. Doesn't appear to have any headroom..
