HiDPI and dual display

Hi

To the left i have a 2K monitor (2560x1440) and to the right i have a full hd monitor (1920x1080).

I try to use an HiDPI on my 2k monitor and an normal one on the other.

I read this page
https://wiki.archlinux.org/index.php/HiDPI

it said

An example of the syntax for a 2560x1440 WQHD 210 DPI laptop monitor (eDP1) using native resolution placed below a 1920x1080 FHD 96 DPI external monitor (HDMI) scaled to match global DPI settings:
xrandr --output eDP1 --auto --pos 0x1458 --output HDMI --scale 1.35x1.35 --auto --pos 0x0 --fb 2592x2898

I tried without success

xrandr --output DP2 --auto --pos 0x0 --output HDMI1 --scale 1.35x1.35 --auto --pos 3456 --fb 2592x2898
seem like my mouse can go on the second monitor

2560x1,35=3456
