CRU - 85hz - text sharpness

Hi,

i used CRU to tune my sharp lc32le350vbk TV.
At 85 hz I noticed that text has "missing pixels" or edges aren't sharp like on 60hz. It's more visible on grey coloured text (some parts/edges of letters not visible).

I tried 85hz without HDMI data block and text is sharp like on 60hz but I had another problem with colours. I see a green colour overlay.

Is there anything that i should enable in CRU/driver settings to make font sharp as i have on 60hz. Or maybe I should change colour settings on TV or in driver settings by reducing green so i will get white color (more or less)

I tried to search before but i didn't find a solution.
I am including 3 images at 60hz, 85hz and 85hz without hdmi data block.
