From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

For three years there has been a bug report around 4K@120Hz being unavailable via HDMI 2.1 on the AMD Linux driver.

The wait continues...

Alright AMD, just remove HDMI from your graphics cards and be done with it 🤷 . Fuck the HDMI forum.

As much as I want them to give HDMI the middle finger I don't think they have enough leverage in the GPU market to pull such a bold move off.

This really bothers me. Closed standards locked behind a licensing fee may as well not be standards at all, in my opinion.

I don't understand why any hardware uses HDMI anymore anyway, what does it have that displayport doesn't?

HDMi foundation is founded by companies who own the home theatre environement (mainly movie conpanies and television) who puts DRM on HDMI to make it harder to illegally copy content like movies, ao they will always want to be anti open source because thats the request of streaming services/movie businesses. Its why for example, mobile devices have widevine levels. those levels basically determine how "unlocked" the device is and services will refuse to offer full functionality to unlocked devices because of it, be it audio or video.

Members of VESA, who control the displaypprt standard are generally computer companies are mostly not in the business of media, so they value specs over drm on changes, which for example a use case is that displayport allows for daisychaining diaplays.

Can hook up to TVs…

CEC (technically I think displayport could support it, but generally isn't implemented) and ethernet up to 100Mbps.

Almost nothing uses ethernet over HDMI to my knowledge.

Decades of being the standard in a/v. That's like asking, why don't we get rid of gas stations and just install electric chargers? Well, everybody's got gas powered cars.

HDMI only had about four good years to itself before DisplayPort showed up. In contrast, the RCA port stuck around for damn near 100 years.

AV things sure since they stick around longer, but computers? When was the last time you saw a high end GPU with VGA or DVI? And they already usually have mostly DisplayPort with just one or two HDMI ports

[–] [email protected] 7 points 1 year ago

Computers are AV things.

Well, I wasn't referring to that ecosystem. That ecosystem is already on display port. The reason HDMI is so prevalent is because it's the standard in audio-visual equipment. Why would I talk about computer equipment when it's not the standard there?

The point still stands. Everybody has equipment that has HDMI, and to phase out that standard in equipment going forward is phasing out equipment people already own.

Feature-wise probably next to nothing, and it's usually behind one or two generations in terms of bandwidth. HDMI is often the only port available on TVs though, so GPU makers likely can't afford to just leave it out.

[–] [email protected] 8 points 1 year ago* (last edited 1 year ago)

They should anyway. New tech TV's are all smart these days and the dumb ones are made for two decades ago. At this point we are better off with a PC monitor and separate speakers. Built in speakers are shit seemingly as a requirement. I use a video port switch for extra inputs without needing to use the on screen menus or just running out of built in ports.

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

Yep. Very common.

A lot of people use their pc like a console or media server. Ie. use it to watch/play stuff from their bed or couch.

Probably a lot more hardware using HDMI than DisplayPort? Just throwing a guess, tbh.

That being said, I might consider looking towards DisplayPort when I can get a new monitor...
