I'm interested in getting a Mac mini Late-2014 (specifically A1347, Macmini7,1, MGEN2LL/A), but I'm concerned by the multi-monitor specifications published by Apple.
The specs state:-
- Support for up to two displays at 2560 by 1600 pixels, both at millions of colors
- Thunderbolt digital video output
- Native Mini DisplayPort output
- DVI output using Mini DisplayPort to DVI Adapter (sold separately)
- VGA output using Mini DisplayPort to VGA Adapter (sold separately)
- Dual-link DVI output using Mini DisplayPort to Dual-Link DVI Adapter (sold separately)
- HDMI video output
- Support for 1080p resolution at up to 60Hz
- Support for 3840-by-2160 resolution at 30Hz
- Support for 4096-by-2160 resolution at 24Hz
- DVI output using HDMI to DVI Adapter (sold separately)
The thing that concerns me is up to two displays at 2560 by 1600 pixels - the 4K resolution alone exceeds the pixel count of 2 2160x1600 monitors, which suggests to me that it might not support a second monitor at all if a 4K is connected. If the 4K already suffers a refresh rate hit, I'm concerned that a second monitor will either push it into slide-show territory, or not work at all. Obviously resolutions can be reduced, but that's a deal-breaker for me.
So, would 2014 Mac minis be able to drive both a 4K (3840x2160) monitor and a 2K (1920x1080) monitor simulataneously? Additionally, would the 4K monitor maintain 30Hz in this configuration?
