It preserves framebuffer geometry through reassertion during launcher and frontend lifecycle events. Video configuration delegates applicable HDMI states to the launcher, and pixel-repetition scaling is updated. ChangesHDMI launcher startup and lifecycle
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: ⚪ Minimal · up to The PR preserves frontend framebuffer ownership and reasserts geometry after output changes; no actionable merge-blocking risk remains beyond normal checks and review. Sequence Diagram(s)sequenceDiagram

Define and declare video_fb_reassert() before using it. support/zaparoo/alt_launcher.cpp:598 calls the function, but no definition exists and video.h declares no prototype. This causes a compile failure. The helper must recompute fb_width, fb_height, brd_x, and brd_y from the current v_cur.
