What's the problem with scaling up by even numbers, i.e. 2:1 or 3:1?

- unwind 3y agoI think the article doesn't consider those to be scaling, which was slightly confusing.
- msephton 3y agoYeah, I could have gone into the differences between native resolution vs integer scaling vs integer scaling with simulated "scan lines". Maybe in another post. This one was written a couple of years ago.
- msephton 3y agoNothing inherently wrong with integer scaling, as long as you are aware you end up seeing more of the colour of each "pixel" as it is 4- or 6-times as big, with less/none of the space in-between, so there is a subtle change to the perception of the image. I'm fine with that I touch on this in the article though I probably could have gone into more depth. I wrote this a couple years ago.
- izacus 3y agoThe biggest issue is that CRT TVs add some bleed/blurring between pixels, which was taken into account when designing artwork. "Pixel perfect" LCDs (upscaled or not) thus show a very different (and less pleasing) picture than what we've seen in CRT era.
- msephton 3y agoYou're spot on. The Philips LCD EDTV that I have is very close to the "aperture grille" look, but of course completely different in how it's achieved (through wide gaps between rows of the RGB triplets).
