I am simply not interested in that sort of limitation on a display device, regardless of the available work arounds. Just sell me an eink monitor and be done with it. This is digital sign technology as can be seen at https://www.visionect.com/products/, and has very little place in the home. It is a waste of resources in that location.

Could you give a few more details on this? While the 32'' screen is a bit too expensive for me, I would probably find interesting usecases for he 16'' version if there weren't the subscription requirement. I don't mind writing my own CMS as long as that's possible.

What are the requirements to make a system work with these? Do you at the end stream bitmaps to the device? Something else? Is there a documented interface?
