The MX123 will also be able to upscale lower resolutions to 8K. The upgrade is in line with McIntosh’s philosophy of continuous product improvement; the 4K version is no longer available.

The MX123 benefits from 10 HDMI inputs and outputs; one of the inputs and two of the outputs will have 8K/60 Hz and 4K/120Hz support (all 10 will continue to support 4K/60 Hz). The three HDMI ports that are 8K/60 Hz- and 4K/120 Hz-compatible, will also offer many other advanced features including Quick Media Switching (QMS); Auto Low Latency Mode (ALLM); Quick Frame Transport (QFT) and Variable Refresh Rate (VRR).
