从edid-decode 所说的来看，在我看来，这个 HDMI 输入只支持 30 FPS 12 位 4:2:0。我是否正确解释了数据？我不确定 HDR10+。支持吗？

看起来我的电视的 HDMI 功能有限，但我想它会准确地显示具有以下视频流的文件，如果在适当的视频卡上使用适当的媒体播放器播放并通过适当的电缆传输：

现场表演：

bitrate: 60748 kb/s
Video: hevc (Main 10), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 3840x2160 [SAR 1:1 DAR 16:9], 25 fps, 25 tbr, 1k tbn, 25 tbc

电影：

bitrate: 73847 kb/s
Video: hevc (Main 10) (HDMV / 0x564D4448), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 3840x2160 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 90k tbn, 23.98 tbc

如果是，那么我应该为此购买什么视频卡？我也希望它保持静音，所以也许移动或嵌入式 APU 可以处理？

对于 12 位 4:2:0，您应该检查自己。

这些视频是 HDR (smpte2084)。
