Digital also loses quality with each generation of compression and jitter, not as substantial as the consumer analog formats but there is a loss that's why its called "lossy compression". There are time when a SD looks far better than the HD and again this comes down to the overall detail, just because it has 1080 progressive lines doesn't mean each line is unique in the sense it wasn't sourced from a lower format and upconverted. Then we can get into things like 4:1:1 sub-sampling, bit error rates and the all important dithering from the low sampling be it 8-bit or the more common 10-bit. How about the compression artifacts like mosquito noise and dynamic pixelations? The modern displays are really good at hiding these things with their 3D filters and other DSP functions but when they're disabled the truth comes out, you can only make a pile of pixels look so good.
Yes 34 inches of 16:9 CRT that covers native unprocessed analog plus HDMI to 1080i due to the CRT itself. It will show you every flaw in that pretty digital image without shame, I have a screen cap from the first StarWars from the original Laserdisc (where Hon shoots first) but the videokarma server won't accept it due to the size. What it does show it the real quality of the image without the dithering or other digital compromises needed to keep the costs low for the consumer world. The image is very bright and dynamic, no highlight crushing or dithering and without the blockiness of the pixelation during the fast action scenes. Once again analog wins this round.
