I would like to buy a large (eg. 13" or at least 10") device for reading PDFs. Based on my Palma experience, and this 2024 thread (https://ledstrain.org/d/3103-different-experience-with-different-boox-products) I am not sure if there are any options:
Would the BOOX GO 10.3 be my only/best option? (but no front light, only 10", not color)
The key comment from that thread is:
The issue is about devices that use BSR (Boox Super Refesh). That's mainly those with a separate GPU (the Tab series) although also includes the Palma (the same software process just using the CPU). You cannot turn BSR off although you can tweak things for minor improvement as mentioned above. So a device like the Go 10.3 will be fine along with the older devices. I currently use a Max Lumi and have ordered a Boox Page. If you want a Palma sized device (I sold mine) then any of the Hisense devices are great and are better devices overall (I've owned many) - although they are no longer made there is still some stock on Ali Express and eBay. Bottom line is that it means you are restricted to e-ink devices that don't try to work around the limits of e-ink technology trying to create a computer-like experience.
As an additional reference I purchased a premium Dell 4K monitor, most painful screen experience in my life.
I have a KOBO Libra (B&W), and it is a pleasure to use, the most comfortable device I have.
