DisplayPort gang?
Sadly also not an open standard, in reality but they are friendlier to FOSS.
At least it is royality free compared to HDMI which has a large annual fee + per unit fee for manufacturers
Oh. It's absolutely superior on the royalties side. Just incredibly frustrating that what should be an open standard that anyone can tinker with is not.
It's at least partially because the specification was designed to detect and thwart attempts to tee the video and audio data in order to bypass copy protection on DVDs and Blu-Rays, iirc.
It is indeed and the fact that I don't care about any of that makes it that much more frustrating. I got bored with piracy nearly two decades ago and just want to implement my own open-source virtual display systems in hardware and gateway I shouldn't need to either cough up thousands of dollars a year or find a copy of a PDF that someone "accidentally" left at a public location in order to do so with an established protocol standard.
Accidental DisplayPort guy checking in. I didn't even know it was a thing until I bought my graphics card. It seems like I dummied my way into some good tech.
Does DP support CEC or ARC nowadays?
sadly not, but GPUs (at least those I used) do not support that over HDMI as well, which is kinda frustrating :/
I was thinking about home cinema, but good point
