downscale

The downscale tag covers issues where high-resolution videos automatically switch to a lower resolution during playback. In one reported case, a user with a 2560x1440 monitor and GTX 780 card experiences 1440p videos dropping to 480p at the ten-second mark when going full-screen on YouTube. After exiting full-screen, the original resolution may become unavailable, though 2160p or 1080p options remain. This behavior occurs with both 4K footage and PC Gamer videos, while games run fine at 1440p. The tag focuses on troubleshooting automatic downscaling during video playback, particularly in web browsers, and may involve graphics driver or browser settings.
