Displayrotate 270 degrees very slow

Dear All,

 

I have kernel 3.10.53 and a display with a resolution of 1280x1024  connected via LVDS.

The display works fine and the updatetime is good if I used rotate 0.

 

If I change the displayrotation to 270 degrees the updaterate of the display is very slow, it seems that the rotation will be done by software.

 

Is there a way to rotate the display by hardware to speed up the udate rate ?

 

Kind regards

 

Wolfgang
