I used to think DisplayPort was the future, about 10-13 years ago.
By now I feel it has come and gone.
HDMI 2.1+ is making its way in everywhere.
It’s a better plug.
It tends to support enough pixels/Hz for most people.
It’s more ubiquitous, being on both TV’s laptops, and monitors.
Pretty sure the PC desktop segment will keep the port alive for a while, but right now it doesn’t seem like a very useful port apart from having a plug that claws itself in place and is often unnecessarily hard to unplug.
With Ultra High Speed HDMI (these names are ridiculous, seriously, look at the standard names) there’s very few, if any, reasons to use DP, apart from compliant HDMI cables costing an arm and a leg.
To be honest I’m struggling a bit to understand why it’s not just all pushed through a CAT6/7 Ethernet cable at this point.
