Poor contrast for fonts and icons

We recently ported our application from PXA320 / WinCE 6.0 to iMX6 / WinEC7. We realized that there are small differences in contrast for the two systems even though the display is the same. The contrast is slightly worse on the newer system (iMX6 / WinEC7). See attached images for comparison.

Is there a way to increase the contrast?

Just an idea: try to change registry

Dear @widtmann,

Thanks for @Frax222 suggestion, that may help you to get similar PXA display output.

Also, play around to match

    "Gamma Value"=dword:000006A4

Please let us know if you have any other questions.

After changing following registry entries the contrast is better:


;Gamma adjustment (value range 1000...2200)
"Gamma Value"=dword:1000

Thank you for your help.
