This is my 40x40 pixel screen I have been working on for the past days, it can store up to 9 images, and those images can be shown at any given time! The total Length and Width of the screen is 80 by 80, each pixel = 2x2. This isn't the smallest pixel possible, but the 1x1 pixel method creates massive amounts of lag when used on such a scale. Because it would be a piston screen, which generates about 3x more lag than redstone lamps! 

Some people messaged me about that it takes very long for your image too load, that's mostly because the pixels on the screen shouldn't be able to interfere with each other, to prevent that, and still keep it compact, you need repeaters, and repeaters slow down the speed...

Although those repeaters slow it down, the rest is made to be as quick as possible, like the wiring going up, it is the quickest way a redstone signal can possibly reach the top, the wiring from the saved images to the screen, also, as fast as possible, but if you have any faster way, please tell me and I'll try to implement it!

I hope you like it!
