The HDMI port has its own, lower VRR window (48-144Hz) versus DisplayPort/USB-C's full 48-180Hz — reaching the panel's true ceiling requires DisplayPort or USB-C specifically. The USB-C port's 7.5W of Power Delivery is only enough for trickle-charging; it cannot sustain a handheld under real gaming load.
