It's about time somebody does some reverse engineering and just uploads the needed stuff online to make HDMI 2.1 work in Linux. It's getting absurd at this point. TV's need to start including Displayport, HDMI is a giant pain in the ass for gamers.
Displayport has DDC/CI, which allows you to adjust things like brightness, volume, etc. remotely. This has existed since the DVI era (!) which means Displayport had a huge headstart. But they never formalized and enforced the DDC/CI spec, which means every monitor has extremely weird quirks. Some will allow you to send and read data. Some will only allow you to send data and crash when you try to read. Some will update only once every few seconds.
Although in this specific case, one wonders why Valve didn't just use two Displayport 1.4 ports and and stuck an onboard HDMI converter in front of one of them, sourced from a company that would be amenable to having Valve work on the firmware of said converter. Make the entire firmware of the converter open source except for the binary blob that handles the Displayport 1.4 -> HDMI 2.1 bits.
Hopefully Valve does this but sells it as a external, high quality converter. It would be a nice little plus even for non-Steam Machine owners, same way like Apple's USB-C to 3.5mm convertor is the highest quality mini DAC on the market for the low price of €10.
I don't know. I have an LG TV and it does not support turning the display on/off with HDMI CEC. Everything else seems to work but it intentionally ignores those commands.
Option 1 (Hidden Menu Method)
* Press the Mute button repeatedly until the hidden menu appears; ensure Auto Power Sync is enabled.
* Go to General → Devices → TV Management and disable Quick Start+.
* Go to General → System → Additional Settings → Home Settings and turn off both options.
Option 2 (Settings Menu Method, webOS)
* Press Settings on the remote and open All Settings.
* Navigate to General → Devices.
* Turn SIMPLINK (HDMI-CEC) ON. (webOS 6.0+, enabling SIMPLINK automatically enables external device control).

Unfortunately, for longer runs, DisplayPort is kind of a nightmare. HDMI tends to "just work" as long as you use fiber optic construction.
They exist for medium-speed HDMI (see for example [0]), but I haven't seen them for modern high-speed DP yet.

This cable is absurdly long. I have no idea how to coil it nicely. At my last place I had three stories, and would sometimes just dangle most of it down to the ground then wind it up from the roof.
The only potential issue is that they seem to be slow waking up from sleep. I've never been interested enough to investigate if moving the PC closer with shorter cables fixes that, or whether it's just an issue with having 2 monitors. I think the underlying cause is actually just because it's Windows and that one monitor (they're supposed to be identical) seems to wake up earlier than the other, so it briefly flashes on, then goes black while it reconfigures for 2 screens and then on again.
But anyway, my 5m cable runs seem fine. They weren't especially expensive nor especially cheap cables, IIRC around 10-15 GBP each.
I wouldn't steal a car, but I would copy one or download one from the internet and 3D-print it.
But Piracy isnt that, you create an unlawful copy, but you didnt steal (IMO)
Which is why i cant participate in the "Is AdBlocker Piracy" debate, because for me, not even piracy is piracy :P
Not defending the HDMI forum here, but perhaps Valve / AMD have a way of including a proprietary blob in SteamOS (I don't think most gamers would care)
I just don't care about the other things in a TV - I don't want smarts, I don't want speakers, I no longer need a tuner.
For a simple example, a TV usually assumes the viewer isn't sitting just inches away from it...
If they sold a 4k 65-75" version of it, I'd buy it in a flash.

DisplayPort actually makes sense as a digital protocol, where-as HDMI inherits all the insane baggage of the analog past & just sucks. HDMI is so awful.
The percentage of people who will actually use DP to connect their TV vs HDMI is tiny. Even people who do have DisplayPort on their monitors will often times connect it with HDMI just because it's the more familiar connector. I spent a decade working in that area and we literally were debating about spending cents on devices that retailed for hundreds, or thousands. The secondary problem that drives that is that ~90% of TVs sold use the same family of chips from MStar, so even if you wanted to go off-track and make something special, you can only do it from off-the-shelf silicon unless you pay a fortune for your own spin of the silicon. If you want to do that then you better commit to buying >1m chips or they won't get out of bed.
HDMI forum was founded by mostly TV manufacturers, they're not interested in constraining the market in that way. It's all just been market consolidation and making TVs cheaper through tighter integration.
Wait what?! This would be jaw-dropping anticompetitive behavior. Could you source this statement?
... we need a digital video link
VESA develops DVI
... market gap for tv's identified
hdmif develops HDMI which is DVI with an audio channel
... while technically a minor feature that audio link was the killer feature for digital tv's and led to hdmi being the popular choice for tv's
VESA develops displayport a packet(vs streaming for DVI and hdmi) based digital link, it's packet nature allows for several interesting features including sending audio, and multiple screens.
... no tv's use it, while display port is better than hdmi it is not better enough to make a difference to the end user and so hdmi remains normal for tv's, you can find a few computer monitor with DP but you have to seek them out.
I will have to see if there is some sort of stupid "additional licensing cost" if a tv is produced with displayport, that would explain so much. I don't claim that there are no tv's with DP but I certainly have never seen one.
Contrast this with the hdmi consortium which put together the hdmi standard. originally hdmi was just dvi with a built in audio channel. and while I will concede that the audio channel was a killer feature and resulted in the huge success of hdmi. They really did very little technical work and what work they did do was end user hostile (hdcp rights management)
It really is too bad that display-port is sort of relegated to computer monitors as it is better designed and less end user hostile than hdmi. but hdmi with it's built in audio channel won the market for digital video connections and by the time display port was out people were, understandably, reluctant to switch again. While display port is better, it is not enough better to be for the end user to care.
