HDMI Splitter - 1 In 2 Out Not Simultaneously

[CRMS]

I'm looking for HDMI switches/splitters for 2 AVRs.

Denon AVRX250BT output max 1080p from satellite receiver, 4K capable but no sat channels yet, to either TV, 1m HDMI lead, or projector, 10m HDMI lead installed 2008. All at 1080p. So I think a fairly basic one will do.

Something like Techole -

Marantz NR1711 output max 8K to TV 1080p 1m lead or Sony native 4K projector, again probably 10m lead, unless I can find 8m lead. So 4K 60Hz HDR etc, so a decent spec one.

Something like TESmart -

Which is powered but limited to 8m cable.

Or this one -

Again powered but up to 15m cable.

Only require one device in operation at a time. All quite complicated!!
