YouTube says it will automatically upscale videos uploaded below 1080p (full-HD to higher resolution using AI. The Google-owned platform, however, assured that it will give creators and viewers the option to opt out of the enhancement. The feature will apply only to videos uploaded in resolutions from 240p to 720p and will not affect videos that creators have already remastered to 1080p. Creators will retain control over their original files, and viewers will be able to watch videos in their uploaded resolution through a settings option.

YouTube said it plans to support upscaling to 4K in the near future. The company also said it is expanding the video thumbnail size limit from 2MB to 50MB to support 4K images. On videos with tagged products, viewers will soon be able to scan a QR code on TV screens to purchase items directly.

75th Trombone writes "I'm a fan of several old PC games — the Myst series, StarCraft, Diablo, etc — with 2D graphics that run at a low, fixed resolution. These games all look horrible on modern LCDs. If you run them at their original resolution, they're tiny, and if you upscale them they get all sorts of blurry, pixelly smoothing artifacts. My ideal goal is to run these games at exactly double their original resolution — running 640 x 480 games at 1280 x 960, for example — so that each original pixel takes up exactly a 2 x 2 block of screen pixels, yielding graphics that are perfectly crisp and decently big. I've tried arcane settings in graphics card drivers (new and old), I've tried forcing the OS to run at a given resolution, and I've tried PowerStrip, all to no avail. Short of writing a new, modern engine for my favorite games, is there a reasonable solution to this problem?" There have been many community-supported graphical overhauls of classic games — feel free to share any you know to work well.
