标注'4K输入'的采集卡多数实际采集分辨率仍为1080p，4K仅指HDMI环出直通监看，选购时需确认'采集分辨率'而非'输入分辨率'的标注

Unverified分辨率标注需区分'物理分辨率'与'兼容/支持分辨率'：标'支持4K'但物理分辨率仅720P/1080P是常见套路，看清DMD芯片实际分辨率86% similarUnverified物理分辨率与'兼容分辨率'是两回事：标'支持4K'但物理分辨率仅1080P甚至720P的机型很常见，看清'原生/物理分辨率'参数84% similarUnverified分辨率为1080P而非4K，追求超高清画质的用户需权衡83% similarUnverified分辨率认准物理分辨率而非'兼容4K'或'支持4K'，真1080P物理分辨率的DMD芯片才是家用底线，很多标'高清'的实际物理仅720P82% similarUnverified分辨率优先看物理分辨率而非'支持4K解码'：车内投影距离短、幕布小（多为60-80英寸），原生1080P已足够清晰，标注'1080P兼容'实为720P的机型不建议购买82% similar
