Muppet Babies probably looked plenty clear on the 20-inch standard-definition TV that sat in the corner of Mom’s living room in the late ’80s. That relatively low-res picture had the equivalent of 25 pixels of image data per inch; blow it up much beyond 32 inches, and Baby Kermit’s nappy would start to split, revealing gaps and jagged edges. Let’s call that size the image’s breaking point. Apply the same density of color blocks to modern high-def screens, and you can figure out just how massive they could get before they’d fissure. Take a look.
