Is that really worth it, though? The 13 inch screen from this company is 899€ and already comes in a proper enclosure, and is wireless which seems important for this product. If your goal is to quickly manufacture reliable devices, partnering with someone that already sells a proper device seems totally worth the extra cost.

Not to mention that OP wants a big poster-size screen, so your suggestion comes a few inches short.

It is absolutely worth it! The Visionect display require a subscription to run properly: https://www.visionect.com/software/ . 60 Euro / year to run a display that I paid almost 1k for is not for private use.

I guess that's why the price for the 32 inch display is so high, the subscription is priced in.

We built our own CMS, so no need for a subscription

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?

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.

I don't think you can buy a large eink screen as a consumer anywhere because of the shenanigans of the company that owns the eink technology. I forgot the exact details, but it was discussed here several times in the past.

It seems reasonable for OP to pay 4x given:

- the display size is 6x

- no need to DIY

It's the size that'll make it feel like a newspaper.
