If you get the right adapter, I've seen others get HDMI CEC working.
However, quality of life features like sleep/hibernate don't work at all on this system. I've also seen people use an ESP32 to power on the system with a bluetooth controller which is pretty neat especially if you combined that with CEC.
I just added CEC to mine today by soldering some wires to my DP-to-HDMI adapter and having Claude write some firmware to run on a Pi Pico to inject the CEC messages at the right time.
It's not the most elegant solution but felt in the spirit of the whole BC-250 experience.
This is why the Steam Machine is worth its money (or, well, what it would have cost if RAM hadn't gone to the sky). Getting 90% of the nice-to-haves costs $200, but getting 100% costs $1000.
I would absolutely not buy assuming this. People used to work hard to get 70W at the socket idle. Things have gotten better, much better, but at the socket those sound like miracle numbers.
Sure any kind of frame rate conversion makes it worse, but lots of 24fps footage has visible judder. The camera can pan fast and the frame rate is too low to show fluidly.
It’s part of the 24fps look, and film makers need to be aware and avoid it as best they can. But judder is definitely a thing at 24fps.
The shutter angle (how much of the 1/24th of a second the film/sensor is exposed for) also makes a difference. The larger it is the more motion blur you get, but it looks smoother. The lower it is the less blur in each frame, but the more obvious the judder as they’re played back.
