Wireless connectivity is essentially a draw: both projectors cover the same ground with Wi-Fi, Bluetooth, AirPlay, Chromecast built-in, Miracast, and DLNA certification. Whether you are streaming from a phone, casting from a laptop, or pulling content from a NAS drive, either device handles it equally well. That said, the Xming Q6 Neo runs Bluetooth 5.3 versus the MoGo 4's 5.1, a modest but real advantage — newer Bluetooth brings slightly improved connection stability and more efficient pairing, which matters most when connecting wireless speakers or audio peripherals.
On wired connectivity, the split is more nuanced. The XGIMI MoGo 4 offers 2 USB ports to the Q6 Neo's single port, which is a practical win for users who want to simultaneously connect a USB drive and a USB audio adapter, or other peripherals without a hub. The Q6 Neo, however, includes a VGA connector — a legacy port the MoGo 4 omits entirely. This matters in specific professional or educational contexts where older laptops or presentation equipment still rely on VGA output.
Neither projector includes an RJ45 ethernet port or S/PDIF audio out, so wired network and optical audio users are out of luck on both. Overall, the connectivity category is tightly contested: the MoGo 4 has a practical edge with its extra USB port for everyday versatility, while the Q6 Neo wins on Bluetooth version and legacy VGA support. Users with modern wireless-first setups will find the MoGo 4 slightly more convenient; those needing VGA compatibility will need the Q6 Neo.
