标称'4K'的低价采集卡多为'4K输入+1080p采集'（4K仅直通不录制），真正录制4K需明确标注'4K60 capture/record'，购买前务必区分输入分辨率与采集分辨率参数

Unverified标称4K的低价采集卡常为'4K输入1080p采集'（即直通支持4K但实际录制降为1080p），选购必须区分'采集分辨率'与'直通分辨率'两个参数90% similar Unverified预算有限时优先保证亮度和分辨率原生规格，而非追求4K标签——部分入门机用0.47DMD芯片抖动实现4K，实际原生1080P抖动到4K，与真原生4K（0.65DMD以上）清晰度有差距79% similar
