My first post got buried in the deep.
I have a brand new Samsung 4K TV. Just received a ROKU Premiere. I have had many years of happy experience with an older model. There are several HMDI connections on the TV, but only one of them supports the other requirements. Obviously I need to double up on that input (output?) Do I need a splitter or a switch? Do I need a 2-1 or a 1-2. Any help would be appreciated including a point out on Amazon. Will I need to go back and forth manually?
Also, the wireless connection is scary. Put an Ethernet hole on that baby!
You definitely need a switch and not a splitter. I have seen them go both ways, but you want 2 (or more) in and 1 out. Make sure you really need it. If only one of your HDMI inputs supports 4k and/or HDCP 2.2 and you only have one 4k device then maybe you can move things around. If you get a switch make sure it supports HDCP 2.2. If the switch doesn't support automatically switching to its active input then you'll probably want one with a remote. If it does support automatically switching then it also has to prioritize its inputs because a Roku is always on. As an example, I have a switch with a Roku and my Blu-ray player connected. The Roku is connected to a lower priority input so when I turn on the Blu-ray player the switch automatically switches to it and when I turn it off it automatically switches to the Roku.
I can't really recommend one because my switch is very cheap and doesn't support 4k. One of these will probably do what you want:
I have two 4K devices, the AV receiver and the Roku. Can I run the Roku in to the AV receiver and then take all of the receiver to the One workable TV port?
But-----my AV receiver has HMDI outlets, but none of the fancy new qualifications. So if I run the Roku through the AV receiver, even though it will end up in the qualified TV HDMI, there will be a whole section of the link going through the unqualified route, thus negating the effect?
So...basically the Premiere has little or no ability to function with 4K TV. I wish the company would make that clear in advertising. Same with the non-Ethernet connection.
I also see now that what I got was a 2019 product. Was this just a cheap attempt to clear the 2019 inventory?
Sorry, I'm not sure what you mean. I thought it was the receiver that possibly didn't do 4K. You could try it and see if it passes through anyway, I have no idea. The Ultra does ethernet. But if you run that through a receiver that doesn't, I think you'd be in the same boat as the one you have now (on the 4K.) I think that's the current Premier. I don't think they rev them all every year.
