McIntosh Announces 8K Upgrade to MX123 AV Processor

McIntosh has announced an 8K compatibility upgrade for the MX123 AV processor.

Originally launched in October 2019, the MX123 launched with 4K/60Hz compatibility, but new versions shipping from the McIntosh factory starting in September 2021 will support 8K/60Hz and 4K/120Hz video resolutions and refresh rates. The MX123 will also be able to upscale lower resolutions to 8K.

Of its 10 HDMI inputs and outputs, one of the inputs and two of the outputs will have 8K/60Hz and 4K/120Hz support (all 10 will continue to support 4K/60Hz). The three HDMI ports that are 8K/60Hz and 4K/120Hz compatible will also offer other advanced features including Quick Media Switching (QMS); Auto Low Latency Mode (ALLM); Quick Frame Transport (QFT); and Variable Refresh Rate (VRR).

All 10 of the HDMI ports support HDCP 2.3, Rec. 2020, 4:4:4 colour spacing, Dynamic Lip-sync, and 3D Video pass-through. And all 10 will also now support a myriad of high dynamic range formats such as HDR (static HDR), Dynamic HDR, HDR10+, HLG, and Dolby Vision (including low latency).
