I’ll hijack this thread and ask, is there any tv that has the ability to change the brightness with a single button press on the remote, or adapts automatically to ambient brightness? On my tv, I have to navigate into 3 menus that take 15 seconds to load. It takes forever. I’d love it if I could repurpose the channel rocker that’s never ever used into a brightness rocker.
