UnverifiedHDR内容采集需采集卡明确支持HDR10直通并配合软件tone-mapping，否则PS5/Xbox开启HDR后画面会发灰发暗，选购时确认支持"HDR pass-through"91% similarUnverifiedHDR采集需采集卡明确支持HDR passthrough和HDR录制，多数中端卡只直通不录制HDR或会做色调映射降级，采集PS5/Xbox HDR游戏需选支持HDR10录制的型号如Elgato 4K60 Pro MK.290% similarUnverified直播/录制采集场景若采集卡不支持HDR，用剥离器把HDR转为SDR比让采集卡强行采HDR后调色更靠谱，此时应确认剥离器支持tone mapping色调映射而非简单截断83% similarUnverified更常见的实际需求是'HDR剥离器/降级器'（HDR转SDR或Dolby Vision转HDR10），用于老投影仪或不支持DV的采集卡，这类需求应搜'HDR splitter/stripper'而非'转换器'78% similarUnverified非HDR真机（无分区背光、峰值亮度<400nit）的'HDR10支持'仅是信号识别，实际HDR效果差；追求HDR体验需认准DisplayHDR 600以上和Mini-LED/局部调光76% similar
