The display is in a state where 80 dots from 1600 to 1680 on the right side are overwritten with black.

OS Ver

 Main unit/dedicated display 20.1 inch wide integrated type
 Resolution: WSXGA+ 1680 x 1050 dots
 Intel Graphics Media Accelerator X4500HD (built into chipset)

1.As a result of displaying with the following settings, the following phenomenon occurs.

  [1600x1050_60.00] is normal operation and right side 80 dot black
  [1680x1050_60.00] & [1680x1050_60.00] are overwritten with black for 80 dots on the right

2.[/var/log/Xorg.0.log] reports the following:
 [   267.320] (II) intel(0): Not using mode "1680x1050_60.00" (exceeds panel dimensions)

3.Of course, Windows Vista displays in intel1680x1050 mode.

My guess is
  The device settings for the panel (embedded LCD) are not normal and are displayed as "exceeds panel dimensions".

I tried various xrandr commands, but they did not work.
Is it possible to change the panel device driver?
