Steps:
---------------------------

./testdisplay -o 9,0


Result:
--------------------------
1.VGA mode show wrong size on screen.
2.It's not full,you can see it on the attachment.

It happens on BayTrail with drm-intel-next-queued and drm-intel-testing kernel.
Comment 1 Daniel Vetter 2013-11-08 07:26:31 UTC 
That can happen with VGA. You need to resync your monitor everytime you switch between machines with the OSD (or sync buttons). The monitor's manual should explain how.
Comment 2 Guo Jinxian 2013-11-22 07:22:08 UTC 
Auto adjust the screen, VGA can shown normally, thanks.
