I don't think I'll add a feature which doesn't make sense, to fix a problem we don't understand =3D). A datasheet I found mentions "One 4.3=E2=80=9D TFT LCD (With Touch panel, CHI HSIN LR043JC211 LCD Model)" And I found: http://www.timll.com/chinese/download/files/CHILIN_TECHNOLOGY.pdf It looks like 24bpp display. What kind of color distortion do you see? Perhaps the problem is somewhere else, like wrong horizontal sync, vertical sync or pixel cloc= k signal setting in .config field. This info should be in the panel datasheet, but it usually takes some deciphering to understand it =3D).
