Switch 2's Handheld Boost Ups Original Games to 1080p on the Go

A new Switch 2 system update (version 22.0.0) adds Handheld Mode Boost, allowing unpatched original Switch games to run in handheld at 1080p by upscaling from 720p. Early tests (e.g., Mario Kart 8 Deluxe, Dragon Quest XI S) show sharper visuals and docked-like detail in handheld, but the feature increases power use and drains battery, disables touchscreen input, and makes Joy-Cons register as a single Pro Controller. Not all games benefit, and patched Switch 2 titles aren’t affected. Enable via System settings > Nintendo Switch Software Handling.
