How Should You Set Overscan/Underscan on Surgical Monitors?
For most OR video chains, the safest default is underscan / 1:1 pixel mapping so the full frame remains visible, including edge UI such as scale bars, measurement markers, patient identifiers, and warning banners. Use overscan only as a last resort to hide unavoidable edge artifacts that cannot be corrected upstream, and keep it minimal because scaling can soften detail, alter geometry, and reduce consistency across side-by-side surgical monitors.
