Unverified85% confidenceDecision RuleTime unknown
老片/DVD/AV源片(480P-720P)超分到1080P效果明显，但超分到4K会暴露原始素材的噪点和压缩瑕疵，反而更糊，低画质源建议只超分到1080P

Unverified分辨率认准物理原生分辨率而非'兼容4K'，0.47英寸DMD芯片为原生1080P，0.33英寸芯片仅720P需抖动补偿到1080P，画质有明显差距81% similarUnverified标称'支持4K'与'物理分辨率4K'是两码事，多数微投物理分辨率仅1080P甚至720P，通过'抖动'技术模拟；选购认物理分辨率标识（如0.47DMD为原生1080P），0.23DMD多为720P抖1080P79% similarUnverified高帧率慢动作（240fps/960fps）分辨率通常降到1080p甚至720p且暗光噪点大，追求慢动作画质需确认是否支持4K120fps而非仅1080p高帧79% similarUnverified分辨率认准物理原生分辨率而非'兼容4K'，0.47英寸DMD芯片为真1080P/4K抖动，0.33英寸芯片实际是720P抖动出的1080P，清晰度差距明显79% similarUnverified分辨率越高越清晰但同容量硬盘可存天数越短：4K相比1080P清晰度提升明显但存储占用约3-4倍，家用监控1080P/4MP在存储与画质间更均衡77% similar
