Graphical Environments & Desktops • Same (Xorg, Linux, conf., monitor size), different HW and DPI

This makes me crazy.

I use the same Xorg version, kernel version,

Code:

$ inxi -GGraphics:  Device-1: AMD Kaveri [Radeon R6/R7 Graphics] driver: amdgpu v: kernel  Device-2: AMD Jet PRO [Radeon R5 M230 / R7 M260DX Radeon 520/610 Mobile]    driver: amdgpu v: kernel  Device-3: Acer Lenovo EasyCamera type: USB driver: uvcvideo  Display: x11 server: X.Org v: 1.21.1.7 driver: X:    loaded: amdgpu,modesetting unloaded: fbdev dri: radeonsi gpu: amdgpu    resolution: 1920x1080~60Hz  API: OpenGL v: 4.6 Mesa 22.3.6 renderer: AMD Radeon R7 Graphics (kaveri    LLVM 15.0.6 DRM 3.54 6.5.0-0.deb12.4-amd64)
(I do not use dedicated graphic card.)

Code:

$ inxi -GGraphics:  Device-1: AMD Barcelo driver: amdgpu v: kernel  Device-2: Sonix USB2.0 HD UVC WebCam driver: uvcvideo type: USB  Display: x11 server: X.Org v: 1.21.1.7 driver: X: loaded: amdgpu    unloaded: fbdev,modesetting,vesa dri: radeonsi gpu: amdgpu    resolution: 1920x1080~60Hz  API: OpenGL v: 4.6 Mesa 23.2.1-1ubuntu3.1 renderer: AMD Radeon Graphics    (renoir LLVM 15.0.7 DRM 3.54 6.5.0-0.deb12.4-amd64)
on both system default configuration except the same file for monitor dimensions:

Code:

$ cat /etc/X11/xorg.conf.d/90-monitor_size.confSection "Monitor"Identifier"<default monitor>"DisplaySize343 193# in millimetersEndSection
With older hardware, AMD Kaveri, Xorg set dimmensions to incorrect:

Code:

 (II) AMDGPU(0): Setting screen physical size to 508 x 285
but with newer one, AMD Barcelo, Xorg size is correct:

Code:

 (II) AMDGPU(0): Setting screen physical size to 343 x 193
Please, where can be cause of this faulty forcing size to 96 DPI?
