The following codecs are supported: (take a guess?). Such as AV1? VP9 etc.
Also tested: media playback (4K HDR supported).........
Reported issues: (take a guess?) Bluetooth dropouts, TB/USB C port runs at USB3 (5Gbps) speed only, when using USB 3.2 Gen 2 SSD drives, WiFi 6 implementation slower than Intel's etc.
TB3/USB4 type C ports supports the following protocols: (take a guess?). Such as (ALT Mode) DisplayPort 1.4 DSC? Can it be used with a 2160p/4K, 10bit, HDR, 120Hz monitor @ full RGB full chroma support?
All in all, some testing would be nice with some peripherals people commonly use, then maybe a review.
As far as the Mac Mini M1 is concerned, when can we expect HDMI 2.1? Maybe DP 2.0 (Alt Mode?).
