Unverified80% confidenceDecision RuleTime unknown

文字/表格办公选DPI 1600足够；设计修图/视频剪辑需DPI≥3200且支持分段调节；静音鼠标多定位轻办公，高DPI高精度传感器（如PAW3395）机型极少且往往不静音

Unverified鼠标精度看传感器：办公无需追求高DPI，1000-1600 DPI足够，剪辑/设计选支持DPI无级调节+高分辨率传感器（如26000 DPI PAW3395），高DPI主要对高刷屏和大屏拼接有意义84% similar Unverified设计工作需高精度定位时，选择支持DPI步进调节（如50或100 DPI步进）且原生分辨率≥16000的传感器，可避免像素级操作的插值失真83% similar UnverifiedDPI高低不等于精度，关键看传感器型号：PixArt PAW3395/3950是当前旗舰传感器（最高26000-30000 DPI），实际使用400-1600 DPI最常用，超高DPI是营销数字80% similar Unverified文档存档扫描选300-600 DPI即可，300 DPI满足OCR识别需求，600 DPI适合含小字号或表格的合同；照片/艺术品数字化才需要1200 DPI以上光学分辨率，插值分辨率数值无实际意义79% similar UnverifiedDPI高低影响移动速度而非精度：日常办公800-1600DPI足够，盲目追求16000+高DPI对文档操作无意义反而难以精确定位；仅设计绘图或高分辨率多屏用户需要更高可调DPI77% similar
