How to control the luminance of display

[Justin_Lin]

Hi all,

I had tried a program which could measuring the lumincace of the LCD display and then modify the luminance of the entire system to make the images or any display have best contrast.

I am very curious about how could a program be able to modify the display effect of the window system. If anyone have any idea about how to control the display effect of the window system, please share your idea with me. Thanks.

Best regards,
Justin

You cannot measure the luminance with a program, you'll need some kind of hardware to measure this.

Dear Marc,

Yes. You are right. We are using some hardware to measure the luminance of the LCD display.

Since we had measured the luminance, we hope that we could adjust the LCD display to let it's appearence be more sharp.

Thanks for your reply.

Best regards,

Ah, didn't know you were already using hardware to measure luminance.

Still, I'm not sure if it would be possible to control the luminance by software. If you want to change it for a program you're writting, you can perhaps use SetColorAdjustment.

Hi Marc,

Thank you very much. I think maybe SetColorAdjustment() is the function that I want. Thank you again. ^_^
