I use testdisplay, then find this bug, I have attached the photograph after
booting. Then you let me start X, and I find it's also shifted.

testdisplay uncorrect mode I have listed when I reported this bug.

current test result like below:
--------------------------------
screen shift right: 
CRTS(3):[0]  1920x1200 60 1920 1968 2000 2080 1200 1203 1209 1235 0x9 0x48
154000

failed to display:
CRTS(3):[1]  1920x1080 60 1920 2040 2248 2576 1080 1081 1084 1118 0x6 0x0
