The HDMI Forum, responsible for the HDMI specification, continues to stonewall open source. Valve's Steam Machine theoretically supports HDMI 2.1, but the mini-PC is software-limited to HDMI 2.0. As a result, more than 60 frames per second at 4K resolution are only possible with limitations.

Are people just forgetting it has a displayport also? Just ignore HDMI, they got greedy, onto the rubbish pile they go.

[–] pressanykeynow@lemmy.world 97 points 3 days ago (1 children)

The people who block HDMI for Linux are also the people who make TVs and other media stuff. So you may not be able to use displayport or hdmi just because some rich people decided so to make more profit.

[–] YiddishMcSquidish@lemmy.today 40 points 3 days ago (1 children)

This is what I said the other day about this issue. Good luck finding a decent tv with display port! Those fuckers are rare and expensive!

[–] Routhinator@startrek.website 24 points 3 days ago (2 children)

They are called monitors, and yeah expensive but then you don't get a "Smart TV" with tracking and bullshit.

[–] sunbeam60@feddit.uk 6 points 3 days ago (3 children)

Nor do you get TV tuners. While most geeks probably couldn’t care less, any associated family do prefer to watch Great British Bake-off as it airs.

[–] Petter1@discuss.tchncs.de 2 points 2 days ago

My country just disabled radio and tv over coax wire and provider send ip-TV boxes.
This allows to have now faster internet, which I like.

[–] Cybersteel@lemmy.world 3 points 3 days ago* (last edited 3 days ago) (1 children)

You could get an external digital tuners and a hdmi switch to switch between pc and the TV.

My grandmother still has an ancient tv with one of those tuner boxes she bought for her tv when analog went off the air.

[–] madjo@feddit.nl 2 points 3 days ago

I would use an Apple TV or a Chromecast in that case. Most TV providers that I know offer their own mediabox anyway, so no need for TV Tuners anymore.

[–] YiddishMcSquidish@lemmy.today 2 points 3 days ago (3 children)

Just told my elderly aunt to not buy a smart tv today!

But do they make 40ish+ monitors?

[–] Routhinator@startrek.website 4 points 3 days ago

They do, but they much more expensive than a smart TV, even though they have less components.. Because a Smart TV is sold for less because its providing the vendor access to you as a product to all of their 3rd party partners.

[–] FG_3479@lemmy.world 2 points 3 days ago (1 children)

It doesn't matter if you get one. They are the cheapest and best image quality TVs available, and many like Samsung's let you set them up without connecting to Wi-Fi.

[–] YiddishMcSquidish@lemmy.today 1 points 3 days ago (1 children)

Yeah, is a fucking sad state of affairs. I actually paid extra for my dumb TV, but then hooked up a jailbroken firestick so I guess I'm a hypocrite.

[–] FG_3479@lemmy.world 1 points 3 days ago

I understand why, but you didn't have to. Many smart TVs let you set them up without Wi-Fi and just use the HDMI ports.

Samsung, LG, and Google TV models do, but Roku and Fire TV do not.

[–] Routhinator@startrek.website 3 points 3 days ago (4 children)

I will add that you can also still get Westinghouse dumb TVs with included DVD player and USB video player, 3x HDMI and a tuner, but 1080p and Max 36"

Basically no modern TV has displayport except for few that come with USB-C

[–] LorIps@lemmy.world 27 points 3 days ago (2 children)

DisplayPort to HDMI adapters are quite cheap and don't add latency.

[–] FalschgeldFurkan@lemmy.world 6 points 3 days ago (1 children)

Aside from practicality, might there be something that gets lost if you do this? (e.g. worse frame rate, quality or sth. else)

[–] LorIps@lemmy.world 18 points 3 days ago* (last edited 3 days ago) (1 children)

No, DisplayPort, DVI-D and HDMI use fundamentally the same protocol, HDMI just adds DRM which requires active adapters when one plugs in a HDMI source into a DisplayPort sink. DisplayPort to HDMI conversions are completely lossless and don't add latency AFAIK.

[–] FalschgeldFurkan@lemmy.world 8 points 3 days ago

Oh wow, all that hassle just for some DRM, as if that would prevent anything... Thanks for clarifying 👍

[–] azvasKvklenko@sh.itjust.works 2 points 2 days ago

Yes, but forget about VRR unless you want to flash a custom firmware and with that the adapter is finky as hell. I use one for 2 years now. It kinda works

[–] echodot@feddit.uk 1 points 2 days ago

It might be possible to get into output wirelessly, it has a dedicated radio for video output so presumably if you just stuck an adaptor into your TV you could just cast to it. Could be quite a nice setup if you wanted it to be able to connect to both your computer in the study and your TV in the living room.

[–] Treczoks@lemmy.world 16 points 3 days ago (2 children)

The problem is that many TVs have HDMI, but no DP.

[–] AshLassay@lemmy.world 10 points 3 days ago (2 children)

Then buy a DP to HDMI 2.1 dongle

[–] chiliedogg@lemmy.world 3 points 3 days ago

What we want is a solution for customers who don't understand the benefit of DP and won't buy an adapter when there's already HDMI ports on both devices.

[–] Treczoks@lemmy.world 4 points 3 days ago

No problem for me, but many consumers don't think that far.

[–] Ronno@feddit.nl 7 points 3 days ago (1 children)

Wouldn't an HDMI to DP cable work then?

[–] Treczoks@lemmy.world 2 points 3 days ago (1 children)

It probably would, but that is already to complicated for most people.

[–] madjo@feddit.nl 7 points 3 days ago (1 children)

Not if Valve packed it in with the Steam Machine.

[–] Treczoks@lemmy.world 5 points 3 days ago

That would be a nice idea, indeed.

[–] douglasg14b@lemmy.world 6 points 3 days ago (1 children)

That's not really how it works given that so many devices have HDMI ports.

If we expect to make hardware devices that are generally compatible with interfaces non-technical users use, then excluding an entire class of common modern interface spec isn't a great choice.

It'll be fine for now but as the specs bump up inversion and HDMI changes over time is just going to get worse

[–] MonkderVierte@lemmy.zip 7 points 3 days ago* (last edited 3 days ago) (1 children)

but as the specs bump

Eh, 4k is already at the point of diminishing returns. There are 8k displays for a while now, but nobody buys them.

Rather, create 5k, please.

[–] TotalCourage007@lemmy.world 2 points 3 days ago (1 children)

I wish game devs knew how to optimize for storage better. Let me install HD instead of 4k games if I choose. I do the same thing for anime series because HD barely takes up any space at all.

[–] MonkderVierte@lemmy.zip 1 points 3 days ago* (last edited 3 days ago) (1 children)

Weell, except some series, where every 20 min HD piece is 1 GB.

[–] Petter1@discuss.tchncs.de 1 points 2 days ago (1 children)
[–] MonkderVierte@lemmy.zip 1 points 2 days ago* (last edited 2 days ago)

No, bad transcoding settings while ripping. Lycoris Recoil is especially bad, 1.5 GB per episode while 300 MB mpeg is usual. Ah, to note that the lossless encoding they use on DVDs is over 6 GB per episode.

[–] anon@lemmy.sdf.org 3 points 3 days ago

VRR? HDMI-CEC?
