Hi everyone

I just got this awesome monitor in order to use it with my Macbook Pro 13 with Touch Bar.

Power charging and USB hub works flawlessly, but I can't get it into Retina mode (HIDPI).

Did anyone experience the same issue? Below the output keeping ALT pressed on the keyboard, in order to show the whole range of available resolutions.

1280x720 HIDPI is not available.

Apple Support was useless.

PS I was able to use it as HIDPI only with SwitchResX, but this doesn't use the whole available space, leaving 2 blank vertical lines on the left and right side.

We should have a screen like this:
