Comment (by cocobean):

 NOTE:
 1. app_server shows display resolution of: 2560 x 1440
 2. Some video display modes 'guessed' and not handled properly by specific
 video driver accelerant:
    a. 1600 x 1200
    b. 2560 x 1440
    c. 2048 x 1536

 If Check mode returns:
    a. B_BAD_VALUE - mode can be made, but outside limits
    b. B_ERROR - not possible

 Then MODE_OUT_SYNC issue.

 Updating video accelerants for modern 'VESA-compliant' display modelines
 may mitigate the 'out of sync' monitor issue.
