Are people just forgetting it has a displayport also? Just ignore HDMI, they got greedy, onto the rubbish pile they go.
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.
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!
They are called monitors, and yeah expensive but then you don't get a "Smart TV" with tracking and bullshit.
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.
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.
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.
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.
Just told my elderly aunt to not buy a smart tv today!
But do they make 40ish+ monitors?
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"
This is big! Where can I buy one for my aunt‽ She needs a dumb TV that integrates with the Westinghouse infrastructure.
This is the one I've gotten two of for kids playroom and bedroom.. They work great, old school simple tech.

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.
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.
Basically no modern TV has displayport except for few that come with USB-C
DisplayPort to HDMI adapters are quite cheap and don't add latency.
Aside from practicality, might there be something that gets lost if you do this? (e.g. worse frame rate, quality or sth. else)
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.
Oh wow, all that hassle just for some DRM, as if that would prevent anything... Thanks for clarifying 👍
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
The problem is that many TVs have HDMI, but no DP.
Then buy a DP to HDMI 2.1 dongle
No problem for me, but many consumers don't think that far.
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.
Wouldn't an HDMI to DP cable work then?
It probably would, but that is already to complicated for most people.
Not if Valve packed it in with the Steam Machine.
That would be a nice idea, indeed.
VRR? HDMI-CEC?
Ok but I need a pretty expensive active adaptor for my tv?
Two considerations: Displayport doesn’t support audio, and there is no connector on the planet more frustrating and unreliable than DisplayPort. It’s like a joke how sensitive it is to the lightest bump. HDMI just works.
DisplayPort absolutely does support audio

You seem knowledgeable, Mr. Vandelay. Perhaps you deal with imports and exports... if so on the topic of audio on DisplayPort, are you aware of any Receivers that will split the signal to send audio to speakers and video to your projector or monitor (TV but there are few)?
Serious question about the receiver if you do know of any - it's come up in the last week while seeing the Valve HDMI news on Lemmy. I found some projectors that have DP, but no receivers and hoping someone here can!
should be able to with hdmi arc, not sure 100% tho but it seems like you could tell the projector where to send the audio, i know you can with tvs and hdmi arc. worst case scenario you do dp in to the projector and hope valve has stereo or optical out to go into reciever
Yes, I have recognised, that if a speaker is connected on the HDMI-ARC port, it will play audio from other input sources to TV still on those speakers. But in my setup, other input sources are HDMI as well..
I know that there are some complicated configurations that you could use to get the audio feed from display port to your receiver,, like running it through a splitter that will strip out the audio and send it to your receiver separately. I'm pretty sure there are no mainstream AV receivers that will do what you want because the market is split between home theatre and PC, as mentioned elsewhere in this thread, and manufacturers need to be convinced there's a market for it.
In that situation, I would connect the output device, in this case a PC, directly to the TV/monitor with DP, and run optical audio from either the TV or the output device to receiver.
You lose some of the integrated control that HDMI-CEC gives you, so get a good universal remote that can adapt to this set up and get one-button source switching back.
I've considered this - I would like multiple sources on my receiver though, so this as you say requires at least a universal or 2 remotes to swap back to the reciever. My projector (current one) only has 2 HDMI Ports. Perhaps in the future this can be my setup.
I run a USB DAC off my pc, then have RCA cables going to my speakers. Usually the DAC built in to a PC or TV is terrible compared to a dedicated one
Didn't know the HDMI cartel could afford bots / useful idiots
They must have found one in the bargain bin.
it's gold plated
I'm not sure where you're getting your information, but displayport absolutely supports audio. In most of the same formats that HDMI does as well.
Also, I've only ever had issues with HDMI plugs. All the displayport plugs I've used had positive locks on them and have been the most reliable plugs I've ever had to use aside from BNC connections.
You could perhaps have instead gone with "you don't find displayport on cheap consumer displays," because that's an accurate statement. That's a huge part of why this is a big deal.
My cat literally loves hiding behind my display port connected monitor, bumps into it all the time, it has never disconnected or stopped working. Your cable might suck.
Where did you hear that? I use DP to connect to my monitor and I can play sound through it.
Ground your shit. Or your cable's bad
I have an HDMI cable somewhere that stops working temporarily when there are changes in temperature, air pressure or planetary alignment.
This is not an HDMI vs DisplayPort issue.
Not everything you don’t like is a bot. I learned something new today that DP supports audio and feel a bit foolish for not knowing that before now, though I stand by my personal experience with the connector. Between work and home, it’s always the DP that flicker at the slightest tap.
Does it have VGA?
