ASRock DeskMini X300 vs DeskMini 310: DisplayPort 1.4 is the main upgrade

The X300 swaps DisplayPort 1.2 for 1.4, enabling higher 4K refresh rates and HDR support. Everything else is identical—same HDMI 2.0, VGA, USB ports, Ethernet, and DC power. The front USB-C remains Gen1 (5Gbps), which feels like a missed opportunity for a refresh.
