When having the mpv window on the secondary screen it estimates the fps based on the primary screen:

Provide following Information:

• mpv version mpv 0.35.0-326-ge1727553
• Windows Version: Microsoft Windows 11 Pro, 10.0.22621, Build 22621
• Source of the mpv binary: https://github.com/shinchiro/mpv-winbuild-cmake/releases/tag/20230317

Reproduction steps

Open MPV via: >mpv --no-config -v -v --log-file=debug.txt --video-sync=display-resample --vo=gpu-next ytdl://https://www.youtube.com/watch?v=7ePaVk7TKGM

Move video from 180Hz main screen to another screen that is 60Hz.

Expected behavior

Estimate should be ~60Hz

Actual behavior

Estimate is 180Hz, taken from the wrong monitor.

I was using a youtube video as demo via ytdl inside mpv (See command up top): https://www.youtube.com/watch?v=7ePaVk7TKGM`

Start by reproducing the issue with the provided mpv command, moving the video between the 180Hz primary display and the 60Hz secondary display, then inspect debug.txt and the linked related issue. Done means the display-sync FPS estimate follows the monitor containing the mpv window and reports approximately 60Hz on the secondary display.
