doesn't get the full list of monitors

[leporel]

pymonctl don't return all my monitors (one of them connected to nvidia card (display port, 144hz), other to motherboard integrated gpu (hdmi 60hz))

• Windows 10 (Windows 11 same behavior's)
• python 3.10.11
• PyMonCtl 0.7

import pymonctl as pmc
from screeninfo import get_monitors

print(pmc.getAllMonitorsDict())
print("--------------")
for m in get_monitors():
    print(str(m))

return:

{'\\\\.\\DISPLAY5': {'system_name': '\\\\.\\DISPLAY5', 'id': 131073, 'is_primary': False, 'position': Point(x=1920, y=0), 'size': Size(width=1920, height=1080), 'workarea': Rect(left=1920, top=0, right=3840, bottom=1050), 'scale': (100, 100), 'dpi': (96, 96), 'orientation': 0, 'frequency': 60, 'colordepth': 32}}

print(pmc.getAllMonitors())
print(pmc.getMonitorsCount())

Monitor1

and this if statement resulting false

Monitor2

win32con.DISPLAY_DEVICE_ATTACHED_TO_DESKTOP show as 1

actually i have 3 monitors, but one disabled in windows (Settings->Display->Disconnect this display), when activate him its seems all 3 display is showing

{'\\\\.\\DISPLAY1': {'system_name': '\\\\.\\DISPLAY1', 'id': 131130, 'is_primary': True, 'position': Point(x=0, y=0), 'size': Size(width=1920, height=1080), 'workarea': Rect(left=0, top=0, right=1920, bottom=1050), 'scale': (100, 100), 'dpi': (96, 96), 'orientation': 0, 'frequency': 144, 'colordepth': 32},

i supposing here is some bug when get dev.StateFlags for DISPLAY1

Hi! Sorry for my late reply. I've been out these days with no access to my "stuff". Thank you a LOT for your feedback!

Let me ask if I properly understood the issue. You start the script with one of your monitors de-activated (detached). Then, at one point, you activate it, but somehow dev.StateFlags doesn't return proper updated value... is this the case?

First off, PyMonCtl is not intended to return non-active or detached monitors... If you need it, we can think of a new function or an input parameter to getMonitors() to force to return ALL monitors despite they are active/online/attached or not.

Please, let me know what you think.

I apologise for my English, I might have expressed my thoughts incorrectly.
No, these my state when i start script:

Windows	Script	dev.StateFlags
DISPLAY1 Active	processed but not returned	2
DISPLAY5 Active	returned	3
DISPLAY2 de-activated	empty?	-

Note: win32api.EnumDisplayMonitors() returned 2 monitors: DISPLAY1 and DISPLAY5 (but in device manager i see 3 monitors, i.e. DISPLAY2 not detached, he just deactivated in windows displays settings)

when i activate DISPLAY2 in windows:

Windows	Script	dev.StateFlags
DISPLAY1 Active	returned	3
DISPLAY5 Active	returned	3
DISPLAY2 Active	returned	3

My problem, when DISPLAY2 de-activated, DISPLAY1 processed as non-active (DISPLAY1 is primary always)

something wrong with StateFlag, he think DISPLAY1 DISPLAY_DEVICE_ATTACHED_TO_DESKTOP is 0 in bitmask

Oh, ok. Understood!! Really weird behavior in deed... Let me dig into it and will come back to you with my findings. We will solve it!!!

Thanks a lot for your feedback and help!!!

Hi again!

Solution found and will be solved in next version!

Checking dev.StateFlag is not really required. It's a remnant from previous versions. Using win32api.EnumDisplayMonitors() and win32api.GetMonitorInfo() is enough to retrieve all required values. It is much simpler now as well.

Thank you for pointing it out!
