The coolest way to display these is to have them sublimation-printed onto fabric (not silkscreened; silkscreening applies the ink heavily enough to reflect sound, while sublimation printing leaves the fabric still soft and porous), then wrap them onto frames containing sound-absorbing material. Hang them around the place and they improve your acoustics and aesthetics simultaneously.
LED walls are cool (and cheap via China) otherwise, and you can start small and then expand if you want since it's relatively modular, just a bunch of square LED panels linked together. You would need a driver though which you may or may not be able to hide behind/somewhere else, makes it kind of bulky compared to just a vertical TV :)
How much is a large digital picture frame,I guess just mounting a tv sideways could work.
