Can you use a 2560x1440 monitor over HDMI with the 2015 Retina MacBook? If so, which one are you using, and are you using the Apple adapter?

I used the Dell U2515H 2560x1440 with an Aukey hub (HDMI and 4x usb3.0).
Had the hub connect with an usbC extension cable to my rMB (base 2015). Very pleased, no issues.
