Dear ALL：

But when we use the hdmi output only, the hdmi can show in TV normally. we use a DVI for capture the log, accessory is the overlay information. some configure error we maybe met ?

thanks

    Check next post

    http://e2e.ti.com/support/omap/f/849/p/221713/781068.aspx

    about the use of

    persist.hwc.docking.enabled

    persist.hwc.mirroring.enabled

    persist.hwc.mirroring.region

    mainly docking value, setting it to zero should remove the full screen, by full screen is it no naivgationbar or statusbar?

    try something like

    stop

    setprop persist.hwc.docking.enabled "0"

    start
