The secondary monitor cannot display

[Zo_yaya]

主显示器的像素为 3840*2160，副显示器的像素为 1680*1050。当 Premiere 窗口的一部分位于辅助监视器上时，辅助监视器不显示回放，并且会受到 win 系统中监视器的显示屏重新排列的影响。我有时需要反复设置分辨率调整，以允许播放功能显示在副屏幕上。

Premiere will not work correctly if part of  it 'bleeds' onto another screen. So what you're trying to do simply will not work.

Create a separate panel group on the other screen, and add panels of Premiere to that panel group. Save as a custom workspace. I have nine custom workspaces, to do a variety of tasks more efficiently across my four monitors.
