The M4 Professional Mac Mini can deal with up to three 6K-resolution screens at 60Hz in excess of Thunderbolt and HDMI. Alternately, for just a two-display configuration, it can perform just one 6K 60Hz screen above Thunderbolt and either an 8K 60Hz or 4K 240Hz display about Thunderbolt or HDMI. https://milojhhfc.aioblogs.com/85885877/ajm-slot-an-overview
