Have a look at https://wiki.archlinux.org/index.php/HiDPI
, in particular
$ gsettings set org.gnome.desktop.interface scaling-factor 2

You can try creating a
custom modeline with the cvt tool, i.e. for 1920x1080
$ cvt 1920 1080
which will give you something like
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088
1120 -hsync +vsync
Then add this to a file like /etc/X11/xorg.conf.d/40-monitor.conf
(create if necessary), according to the following format
Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081
1084 1118 -hsync +vsync
Option "PreferredMode" "1920x1080_60.00"
Use xrandr -q to find out the display identifier (i.e. eDP-1 in the
example). PreferredMode is optional, to tell the xserver to default to
the specified mode.
Then reboot or login/logout and look if this mode works better.

isn't really a graphics-card thing, rather a that the toolkit (Qt,
Gtk) needs to be HiDPI aware and configured accordingly
Hope this helps
