Funny thing - I tried the link and the best value revealed to be 2.6. It 
is quite tough, as my eye is comforted
when gamma is set to 1.2 ;) I watch many photos on screen, and they are 
all displayed good, much better than
on other systems. So I really doubt I understand what 2.6 exactly means. 
Not kgamma's values for sure.

I think your problem is somehow garbled settings of graphics chip, since 
it can set gamma for usual screen
and overlay surface independently. Possibly, it thinks about gamma 0.5 
on overlay or so. But I do not know
how to tune it in linux, unfortunately. I also wish sometimes to alter 
overlay's gamma, but nVidia driver does
not allow me to do it.
