screen tearing when hdmi output and dsi output

hello,
nvidia jetson tx1 connects two screens.

#xrandr
screen 0: minimum 8x8,current 2000x1024,maximum 16384x16384
DSI-0 connected 720x576+1280+0 (normal left inverted right x axis y axis) 0mm x 0mm
720x576 59.88*+
HDMI-0 connected primary 1280x1024+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1280x1024. 60.00*+

But, there is a screen tearing with dual monitor. Then I use HDMI-0 only,there is no tearing.

How to display the screen correctly?
I would appreciate any help and explanations.
