thanks masseur

I've cryed for this ever since my first K750, and noticed the problem with gamma (contrast) compared to my K700

This hack really improves the overall visual experience of the screen, and themes, pictures, videos, games now looks like it should

I cant make an accurate screenshot comparison, because the change are propably to subtle to show in a normal photograph of the screen, and I cant control the photographing good enough to be 100% the same both times i take a picture.

And this doesnt work for all K750/W800, cause not all tft panels are the same, so not all have this gamma issue.

Those that do have the gamma issue, and are graphically minded, experience a wrong whitelevel, making colors wrong (to bright) compared to photoshop when making themes, with whiteburns and to bright blacklevels. This also causes compression artefakts in black areas of videos to be shown more clearly, and bright areas to wash out in general.

Therefore if your screen is allready correct gammalevel, this driver is not needed and you may instead experience the screenpixels to show more clearly (by some called increased graininess), but if you do have one of the K750's with wrong gammalevel you will see improvement with this driver immediately. If you have ever compared one with correct gammalevel to one with wrong gammalevel you will know the difference.

If you have doubts, try it and see which you prefer, it wont do any harm to your phone, and you can allways switch back to the default one (allways remember to back up your default driver)

Ok the driver definitely gives more contrast which is good. However.. maybe it's only me, but I find images have blurred quite a bit. Maybe you can check up on that.
