    OK I just bought this splitter from Amazon and it does just what I needed. I am sending the signal to two different resolution TV's and they are each getting the correct resolutions. The lower HD TV does not cause the 4K to lower to the same resolution of the HD TV.

    I am glad you found something that will work for you! Unfortunately, it sounds like it may not be a solution for me:

    When the input is 1080p, then the outputs are 1080p. It will not show on the 720p TV because the source is a higher resolution. The only way it will work is if you change the source signal to a 720p signal so both 1080p and 720p will display the image.

    Let me see if I understand… When input is 1080p… And the outputs are 1080p and 720p… As long as the 1080p output doesn’t down-speed to 720p… Would this work for me?

    Most HDMI splitter won't re-scale. So, if you want the signal to go everywhere, you have to send the Least Common Denominator - a signal which all the display devices can deal with.

    Exactly. Which is why I can't get my head around this post:

    Are you saying you are getting HD (1080p or lower) on one TV and 4k on another TV at the same time? This would be a first for a splitter, as every other splitter at that price point will not include a scaler to down sample the 4k to HD for a lower resolution TV on one of the outputs. Typically the TV with the lowest common denominator dictates the resolution and audio outputs for all TV's on the splitter. It would be more likely (but still very unusual) that you can only watch one TV at a time if you want the 4k TV to get 4k.

    Please get back to us on that as I am very interested to hear your confirmation.

    If you have a TV on the splitter that only supports 720p and no higher, than you would need to set the TiVo to 720p for both TV's to work. The 1080p TV will get a 720p signal and work and the the 720p TV will get a 720p signal and work. If you set the TiVo to 1080p the 720p TV will not work.

    Might not some tvs take that 1080p and downrez to the tv's native format, allowing the 1080p tv to get full HD?

    Sure, there are plenty of TV’s with a native resolution below 1080p that will still accept 1080p and downrez the signal to match the TV’s native resolution. This includes 720p and 480p TV’s, as well as anything below 1080. Many TV’s will do that.

    I should have been more clear, but it was late and I was thinking of a 720p TV that could not accept signals above 720p.

    There are also older HDTV’s that can only accept 1080i and cannot accept 1080p or 720p (Mitsubishi mostly).
