Logon screen, shutdown screen, and lock screen are not displayed in full-screen mode after you change the screen resolution to 3200 × 1800 in Windows 7 SP1 or Windows Server 2008 R2 SP1

Symptoms

Assume that you change the screen resolution to 3200 × 1800 on a computer that is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1. After you restart the computer, the logon screen, shutdown screen, and lock screen are not displayed in full-screen mode.

Cause

This issue occurs because 2560 × 1600 is the maximum screen resolution that you can use to view the logon screen, shutdown screen, and lock screen in full-screen mode.

    Version

    Product

    Milestone

    Service branch

    6.1.760
    1.18xxx

    Windows 7 and Windows Server 2008 R2
