Default New Acer monitor problems

Hi-DPI (it's 2X of an HD monitor at 1920x1080).

So you're driving it with the wrong video card and it's
not running native for starters.

It is at its native resolution, no doubt of that.

Have a look through Wikipedia in the HDMI and DisplayPort
sections for details. VGA can't go that high, and VGA
typically stops at 2560 or so (the VGA spec is unlimited,
but DACs don't go that high). The dual link DVI won't
go that high either.

DVI dual link 2560x1600 at 60Hz

We're using a DVI connection. The resolution is the full 3840 x 2160
