Applications appear small on my new 4k 80cm monitor.

Hi,
Just bought a new 80cm 4K 144hz HDR monitor.

I use dwm on X11.
Everything is working, except that all applications appear small.

I increased font size in my dwm config.

I don't know how to change the scale of applications.

Is there any command like tool or config i forget to set/use?

Thanks.

Try xrandr

the short answer is that it is likely that your Horizontal and Vertical settings in X is probably wrong (it is too large)  How to debug it takes a lot more information - like your X log output and HW information (man hwinfo).

DPI ?

A screenshot would help :)

On ~/.Xresources:

Code: [Select]
Xft.dpi: <value>

On the office laptop I need there 150, but when using a bigger monitor I need 123.  Doing the scale thing with xrandr for example is really ugly to my eyes, the fonts get like blurry, and what x11 does underneath is virtually resize the monitor.  The best I've found is playing around with Xft.dpi.  The resources need to be reloaded after changing, or get out and get back in to the x11 session.

This was already fixed on x11 to get the right Xft.dpi according to the monitor size (h x v dimensions) which are detected by x11 underneath, but the developers of xorg reverted it because Qt was doing some dirty magic assuming always a 96 Xft.dpi value.  I'm hoping the issue xserver should correctly set DPI for screens (restore ~pre-2010 behaviour) gets positively fixed.

Alright.
Got it.
It works now.

The other solutions mentioned above are no doubt better, but in most desktops you can usually select a screen resolution lower than maximum in the menus, which makes everything bigger. This can be useful if you boot a live USB and you don't want to mess about setting things up.

seriously, that is one of the worst written support documentations I've seen.  It is not suitable for those not emersed in the technical details of screen displays and technology.   And I disagree that this needs to be fixed through Gnome or KDE.  This is an essential problem with screen rendering and it is fixed either on X directly or wayland.  Stretching the screen on top of a misconfigured display is really putting lipstick on a pig.  If the DPI is not correct, or the geometry for the display is off, it needs to be addressed first.
