@Aike: I found the entry <polling>false</polling> in
~/.local/screen-configurations.xml. Yes, it is false.

However, I need to clarify something about the laptop I am using. Its an HP
Compaq 6530b. The laptop, per se, does not have an HDMI port. But the docking
station I use has HDMI port. 

xrandr -q gives:

Screen 0: minimum 320 x 200, current 1440 x 1950, maximum 2400 x 2400

   640x400        85.1
   640x350        85.1
HDMI-2 disconnected (normal left inverted right x axis y axis)
TV disconnected (normal left inverted right x axis y axis)

The external monitor is HP LP2065. It has a VGA as well as HDMI input.
Currently, I am using HDMI port with 1400x1050 resolution. However, if I switch
to the optimal resolution of 1600x1200, I cannot open a browser window
maximized on the external monitor. It just goes blank and then blinks at
regular interval. If, however, I have konsole on the external monitor, it works
fine (even maximized.) 

At 1400x1050, everything is working well, though.

I hope this gives some more insight into the issue.

Cheers.
