xrandr causes flickering

Hey
i want to set the display-resolution to 1920x1080 (the native display-resolution) on a HP Pavilion 15.
The xrandr-output is:

 
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 16384 x 16384
eDP connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 345mm x 194mm
   1366x768      59.99*+  40.00  
   1280x720      59.86  
   1152x768      59.78  
   1024x768      59.92  
   800x600       59.86  
   848x480       59.66  
   720x480       59.71  
   640x480       59.38  
VGA-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)

so i tried

cvt 1920 1080                                                                                                         
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

and

xrandr -- newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

xrandr --addmode 1920x1080_60.00

xrandr --output eDP --mode 1920x1080_60.00  

but than, the display is flickering and not usable in any way.
Not only 60Hz but also 30Hz doesn't work for me.

Do you have any ideas how to set the resolution to the native FullHD?

Re: xrandr causes flickering

I had a similar flicker problem twice. In both cases, using xrandr to rotate the screen by an unobservably small angle 'fixed' it.
