Yes, subpixel rendering of fonts looks worse than greyscale only.
I can confirm that changing the gamma values (independently of each other,
different combinations tried) using xgamma did not change the color #FFFF00 on
display, not even slightly. Always looks like lime instead of yellow. Something
else must be going wrong.
You think that using a calorimeter (like a ColorHug?) to create a color profile
would help correct the inaccuracy? I would not want to spend €80+ on such a
device and find out it was for naught.
But since it seems they did something on Windows to make color accuracy better,
there must be something we could do on the linux side of things?
I contacted Lenovo customer support about the issue, but only got an unfriendly
answer back, forwarding me to the "official fix" page.
Is there any help to be expected from Lenovo's side? I think it would be in
their best interest to come up with a good solution for this, since they
marketed this Ultrabook as a device for professional designers and such, but
bad colors make it more or less useless for professionals ...
Should I try to get in contact with them regarding what exactly they did to
improve color rendering?
