The screen is available on Amazon? But it's a touch screen, which seems overkill; any screen would probably work? One can always build a custom frame around it.
Touch screen I think is cool because then you could interact with the art.
I did a little research and these Waveshare displays look really beautiful. For a particular size display, they have models in different resolutions (from lower to higher res). But they're only for rpis and windows, not like mac or ipad. The QLED ones are the best.
