a 1920x1080 screen at 15.6" will have the same calculated dpi as a 4k screen at 32".
Similar, yes, but not the same. 15.6 is 141.3. 32 is 137.7 (if 32 is in fact 32 and not 31.5).
While the latter needs dpi scaling, the former does not.
All else being equal, two different sized screens having the same density (DPI) will render objects at the exact same physical size regardless of the screen resolution that produced it. What matters in determining whether scaling is indicated is the relationship between density and viewing distance. Without knowing the viewing distance it can only be guessed whether scaling might be called for. Note that when the current problem with the installer is known, we have from linuxrc e.g. XVideo=1680x1050,108 that would scale up sizes on that 15.6" 1920x1080 laptop screen considerably, and e.g. XVideo=1920x1080,132 to do considerably more scaling on that 4+ times larger 32" 4k. -- You are receiving this mail because: You are on the CC list for the bug.
