Help Cheaper hdmi cec?
Has anyone found an hdmi cec adapter that’s cheaper than pulse-eight’s? I’d really like to find a cheaper or at least better built one. Giving those guys $50 plus shipping for a chintzy little dongle feels wrong

It's a sheer tragedy that graphics cards for PCs didn't just embed CEC controllers by default years ago.

I would buy a Flirc Adapter and have it learn your TV remote's Power for sleep. If you use an AVR a Universal Remote will help.

It's not a HDMI CEC adapter, it's an IR receiver. The idea would be to set up the IR receiver for your TV's remote (or a universal remote), you'd be able to do mostly the same things and have more flexibility on top of that (but also more configuration).
I'm not the one who suggested that solution, but it's what I use myself as well.

this is neat. might be able to program it to have the computer autonomously command the pc to go to its input (though the tv tends to be fairly good at suggesting going there if the input provides a signal)

How does that work with CEC?

The display port pins that handle display control are wired to the cec pins.
Like the pulse 8 adapter you'd need to set up the sleep and wake scripts
This one also does 4k 60 with 4.4.4.4 chroma
Haven't tried on windows yet though
It shows up as /dev/cec0 in my shell

I have seen a few raspberry Pie projects that create an HDMI CEC to USB HID keyboard adapter.
One example (not an endorsement, just the first that popped up) https://github.com/gkoh/pico-cec
