I really wish I could find a TV within my desired specs that had DisplayPort. We will buy a Steam Machine to use it in place of our docked Steam Deck in the living room, so being able to use DP would be amazing.
Adapting DisplayPort to HDMI with minimal quality loss is child's play. It's the other way around that's misery.
Any cheap adapter cable that supports DisplayPort In to HDMI Out should be perfectly fine.
I just realized I have such cable in my desk (brand new), DP to HDMI 4k 60fps
My spouse need something for the other way around for his desk setup
Those specs sound like HDMI 2 anyway. HDMI 2.1 can do 4K @ 144Hz with HDR. Or apparently even 10K @ 120Hz.
But the big thing with HDMI 2.1 is the cec protocol which doesn't translate over an adapter unfortunately. But it is a very tiny thing most people won't care about.
Would be cool if they put one in the box. Would save many sad christmas days as you wait for Amazon to come round with an adapter.
i want to say you can buy an adapter to get dp 1.4 out of steam machine and into hdmi 2.1 on a tv and should be fine. just has to be a powered adapter i believe
The powered adapters are for the other way around. DP has support for HDMI out without additional components, but ofc the HDMI forum makes converting HDMI to DP like pulling teeth.
