Power Display: Inconsistent triple monitor detection after Maximum Compatibility update

Microsoft PowerToys version

v0.100.2

Installation method

WinGet

Area(s) with issue?

Power Display

Steps to reproduce

1. Connect a triple monitor setup (dual monitors work fine).
2. Open PowerToys > Power Display (or equivalent monitor control module).
3. Observe that the third monitor is not detected/displayed.
4. In some sessions, only two monitors appear, and for those, brightness, contrast, and sound sliders are greyed out / unavailable rather than showing full controls.

✔️ Expected Behavior

All connected monitors (including triple monitor setups) should be detected consistently, with full brightness, contrast, and volume slider controls available for each detected display.

❌ Actual Behavior

• Dual monitor setups work correctly since the Maximum Compatibility update.
• Triple monitor setups intermittently fail to detect the third display.
• When only two monitors are shown (in a triple setup), some controls (brightness/contrast/sound sliders) are missing or disabled rather than fully functional.
