Also, when using the HDMI output, a workaround the black bars is to have some kind of background, like these: Sometimes people do atrocities, in which case I would prefer the black bars. But when it is well done, I like it.

Great. Being able to rotate is also great. I can't stand playing with a distorted image, my eyes hurt when I see it, like in your videos. But the black bars on the side are distracting to you, and you hate those, so different strokes for different folks. Your heart is in the right place, and I am glad that you found a solution. And the tinted window should work nice too. Good luck with the project.

You can have it playing in 4:3 on the 16:9 screen, you just need to adjust the software settings. I would prefer a 4:3 screen, but I don't think it would make a difference in your design, since the size of a 4:3 screen that would fit is the same that you will get using a 16:9 with black bars on the sides. And, as you said, the ones that are cheap and readily available are wide. And adjust the settings to display it in 4:3 when using the HDMI out too.
