It requires compatible GPUs, but it's how early 5k@60Hz displays were connected using DisplayPort 1.2, and how very large displays are connected in general. Among displays that used this was for example Dell UP2715K and early LG UltraF

Which is why in my experience on computer hw it's common to see one, maybe two HDMI (among other reasons, to support things like connecting a console to your monitor), and multiple display port connectors - sometimes it goes ridiculous

No, that's the point of DisplayPort in being royalty-free and unencumbered. HDMI was deeply intertwined with the brave new world of Protected Media Path.

Well, yes. Another part that prevented more rapid adoption of DP2.0 other than longer and longer upgrade cycle of GPUs and displays is that another option is to just use 2 cables for 51 Gbit/s which was also a thing with early 4k displ

The decision to replace VGA with HDMI on Thinkpads was literally driven by market research deciding that likelihood of encountering HDMI setups was bigger than VGA by then.

The point of HDMI port is that access to it is controlled by the consortium, and that it includes DRM. This isn't necessarily compatible with FOSS.

Usually it's raw DisplayPort connection using some of the SuperSpeed lanes on USB3/USB-C connector. Encapsulation is optionally available when running Thunderbolt/USB4 on the port, then between consenting devices you can setu

The manufacturers very much care - every HDMI port (physical or virtual ) involves tithe to the HDMI consortium, whereas DisplayPort does not.

IIRC main difference was that DP1.4 at 26gbit was more than enough to drive 4k displays

It's worth it because it matters to simple cases of normal user needing a converter dongle. Passive USB-C DP-altmode to DP cable are easy to acquire, cheap, and work fine. USB-C -> HDMI is usually expensive because nearly nobody use

Interesting, I don't think I've seen VGA anywhere outside retro setups or places that were setup once long ago and left like that. I think many people don't even know there was such a thing as VGA these days if they work in o

Thinkpads will usually have multiple DisplayPorts (some as alt-mode on USB-C), and 1 HDMI for use with roach-motel-quality conference room setups.

DRM is pretty much mandatory in HDMI in home entertainment setup, and is controlled by the media companies' cabal, which is important to vendors in that space (who are often members too). Also, lowest common denominator HDMI in TV form

HDMI replaced VGA as the "lowest common denominator port" for conference usage, not as major display tech. HDMI is also for various reasons very tightly bound with home entertainment ecosystem because the DRM is mandatory while it

And then you went and got even less on track, because offering multiple engines and re-engining aircraft is the norm , sometimes to very different engines (like Russian engines offered as upgrades to old Mirages)

737 MAX had nothing to do with replaceable engines, but with trying to run an ancient airframe with new engines but without necessary upgrades to support the new engines because of costs.

The very reason for the Loop Buffer was to let decoder power down within tight loops, so I'd assume micro op cache would have similar effect, except with more impact on performance.
