> No device output in DP

Yeah, if we exclude basically every half decent GPU and ~70% of laptop USB-C ports in existence.

I was talking about the TV room device, as opposed to the computer devices.
I use an HDMI to HDMI cable to connect my MBP to my 38" monitor (3840 x 1600, @ 85Hz). Would I get any benefit from using a USB-C to DP cable instead (e.g. running at the monitors maximum refresh rate)?
Unanswerable without specifying what laptop you have.
Sorry, I should have Googled before asking the question. I just did, and see that my monitor (Dell AW3821DW) supports only 85Hz over HDMI, but up to 144Hz over DisplayPort.

The laptop's spec page doesn't say what refresh rates are supported for external displays (except saying at least 60Hz): https://support.apple.com/en-us/111901

I'll buy a new cable right now :)

Yes that macbook pro supports outputting even 4K @ 144hz over displayport so it should work easily.
With the new cable, MacOS is showing the refresh rate is variable 1Hz to 144Hz.
Those generally aren't in the living room
