The HDMI Forum has rejected our proposal unfortunately. At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements.

Why did HDMI succeed over display port? Always the same problems with closed source.

[–] [email protected] 0 points 8 months ago (1 children)

In my experience, its cause monitors are already over priced, and adding a display port to it seems to add at least another 100 on top of that.

Which is why I prefer HDMI. Less cable headache too, since I only have to keep one type of cable in stock and so i can easily switch for testing/diagnostics/layout change purposes.

I... don't think display ports add 100 on top of the price. Do you have a source for it that its so much more expensive?

[–] [email protected] 0 points 8 months ago (1 children)

HDMI didn't succeed over display port; they're two different formats meant for two different audiences.

  • HDMI is meant for consumer electronics like TVs / set-top boxes because it focuses on delivering a little bit of everything (audio, video, network, etc) in a single cable for the best, easiest singular TV / device experience.

  • Display port is meant for computers because it focuses on delivering the best responsive multi-monitor experience.

In other words, if you are working or gaming on a computer, you should be using Display port; however, if you are using anything else, you should be using HDMI.

I just hate how my monitor came with a HDMI cable

[–] [email protected] 0 points 8 months ago (1 children)

Regardless of the cable that came attached, check the monitor to see if it supports a Display port -- It most likely does. Your monitor likely came with an HDMI cable for sake of cost reduction (I guess better than no cable at all). If the monitor doesn't support Display port, it means that manufacturer didn't build or manufacture that monitor to be a true computer monitor class product.

I know it's probably for cost cutting. But the monitor does indeed have a DP input option. Maybe the HDMI is included because it has inbuilt speakers and as far as I know those aren't usable thrpugh DP and I don't know if it has a separate audio input.

HDMI did have a head start, but nowadays, the answer is money. As usual.

[–] [email protected] 0 points 8 months ago (1 children)

That also includes money to upgrade, for example, display equipment in virtually every office conference room, classroom, home theater, etc. It took a long time to shake VGA in those settings and now that that's largely been dropped in favor of HDMI it'll be a tall order to chase after the next best thing with no benefit noticeable to 99.9% of people.

Fair, but the same was said about USB. We got there eventually.

[–] [email protected] 0 points 8 months ago* (last edited 8 months ago) (1 children)

It's an older interface than DP and has "better" support for audio (I.e. all of those proprietary passthrough audio formats that home theater setups support) so it became dominant in TVs. Monitors are still DP first but likely have a HDMI port as well.

Most modern monitors have a single displayport, and then a small army of HDMIs.

[–] [email protected] 0 points 8 months ago

That kind of makes sense though. I figure they assume you’ll have one computer hooked up and then a bunch of consumer devices that all use HDMI. And if you need a second computer hooked up you can also use HDMI if needed. Probably makes the most sense to the most people as having more DP in place of HDMI would just mean the average user couldn’t hook up as many devices since (almost?) no consumer devices use DP unfortunately.

You forget every desktop GPU having 3 DisplayPorts and only 1 HDMI, and USB C supporting DisplayPort?

[–] [email protected] 0 points 8 months ago (2 children)

Because the movie studio execs like their hdcp drm

[–] [email protected] 0 points 8 months ago

Which is funny because of how easy it is to circumvent

[–] [email protected] 0 points 8 months ago

Which in a lot of cases can be easily removed with adding an HDMI splitter in between. Fuck DRM!

Is display port still open source? I thought something happened.
