Comment(by gang65):

 This bug (wrong resolution 1366x768) occurs when radio is activated.

 When radio is deactivated the resolution is correct (1024x600).

 This happened because when the radio is deactivated, the screen resolution
 is taken from EDID:

 But when radio is activated the resolution was taken from scratch
 (ViaPanelGetNativeModeFromScratchPad function):

 I don't know why this happened.
