OpenScreen() always fails

[Little John]

Code: Select all

Define.i w, h, d, count=0

If InitSprite() = 0
   Debug "Error with InitSprite()"
   End
EndIf  

If ExamineScreenModes()
   While NextScreenMode()
      count + 1
      If OpenScreen(ScreenModeWidth(), ScreenModeHeight(), ScreenModeDepth(), "Test")
         w = ScreenModeWidth()
         h = ScreenModeHeight()
         d = ScreenModeDepth()
         CloseScreen()
         Break
      EndIf
   Wend
EndIf

Debug Str(count) + " screen modes tested"
Debug Str(w) + "x" + Str(h) + "x" + Str(d)

With both PB 6.04 LTS (x64) and PB 6.12 LTS (x64) on my ASUS ZenBook Flip 13 with Windows 11 Pro, I'm getting this result:

51 screen modes tested
0x0x0

There is no known problem with the hardware or with the operating system.
Does anybody have an idea what could be the reason why OpenScreen() does not work?

@SPH:
It's fine that your code works on your computer.
However, on my computer your code yields the same result as my code above, as expected.

Nowadays, fullscreen is mostly done by using a top borderless window to avoid changing screen resolution as the final rendering speed isn't really impacted. You can try with the DX11 subsystem to see if it works here.

When using the DirectX11 subsystem, it works fine on my notebook. Many thanks!
