Need dedicated HDMI splitter

[animematic]

Hi so can anyone tell me where I could buy a HDMI splitter? Wanna be able to hook my computer up to 2 TVs and one of them is a slightly older model.
I tried using one of those dual Splitter/Switches but that didn't work so looking for one thats just a splitter

Do you need them to be identical output to each other? Because that's what a splitter would do.
