Is it possible to set DPI larger than 250 on Windows 11?

The highest DPI can be set by setDpi.exe seems to be constrained to 250 on Windows 11

Yes, if your computer supports it. That is, i believe the upper limit is determined by your computer. If your display settings can go to 300 then SetDPI can go to 300. My AHK / SetDPI script on Windows 11 toggles between 175, 225, 300 without any problems.

this is the script i use and it successfully tri-toggles up to 300 dpi

#Requires AutoHotkey v2.0

; Define the DPI scaling values for the three states. 
DPIScalingValues := ["175", "225", "300"]	;These must be actually available per the Display Settings (cant do 314.15)
CurrentState := 1					;global by default since defined above function

; Path to the SetDPI.exe tool, note the space after exe
SetDPIPath := "C:\Users\... your path ...\SetDPI\SetDpi.exe "

; Toggle between the three DPI scaling states when Ctrl + Win + F1 is pressed
^#F1::
{
    global DPIScalingValue := DPIScalingValues[CurrentState]

    ; Run the SetDPI.exe tool with the specified DPI scaling value
    Run SetDPIPath DPIScalingValue

	Switch CurrentState
	{
		case 1: global CurrentState := 2
		case 2: global CurrentState := 3
		case 3: global CurrentState := 1
	}

}

Hi. Sorry that it has been a long time and I suddenly recalled this issue.

I'm able to change DPI to a very high value by modifying reg like this:

HKEY_CURRENT_USER\Control Panel\Desktop" /v LogPixels /t REG_DWORD /d 350/f
and log off and on windows.

but when using setDPI, setting 350 has no difference with setting 250, I remember Win10 doesn't have problem with that. Any clue on this?
