A:Answer It has something better than a manual MUX. I'm sorry to say that Acer's response is not 100% correct. It has Dynamic Display Switching and Advance Optimus. Which means it has a MUX switch that enables dGPU to directly connect to your internal displays. Instead of a manual MUX, which requires a manual reboot, my Helios 300 RTX3070 Ti, and my friend's Helios 300 RTX 3060 do not require a manual reboot. I also have a 2022 Zephyrus G14, which a manual MUX. I wish all OEMs would implement what Acer did.
