Part Number: TDA3XEVM
Hi Everyone ,
I like to know is there any possible ways to control the RGB gain, brightness / contrast of the display from the TDA3x . I like to know whether these parameters can be controlled through software .
Thanks & Regards ,

Hi Brijesh , I have enabled the above mentioned register and tried , but I could not see the image on the display . I tried with different coefficients value still I could not adjust the RGB gain of the display. Kindly help us on this and also let me know if I have missed anything.
What is your input format? which display pipeline you are using?
The CSC module will be definitely used if your input format is YUV and you are doing some blending operation. It is not possible that change does not take any effect if it is getting used. You must be using either using difference pipeline or your input format is not YUV.
It is even strange that CPR is not working. I have used CPR and it works fine. Are you enabling CPR for the correct output? TDA2x supports multiple outputs, so if you are not enabling it in correct output, you will not see its effect. Check the overlay manager and LCD output that you are using and enable CPR accordingly.
Hi Brijesh , We are not sure about the following things : 1) Input format 2) Display pipeline We are currently using rear view panorama usecase on TDA3x platform and the output is VIP LCD display . The observations which we found is we could enable Gamma output whereas the CPR even after enabling we couldnt see changes in the display . I also like to know whether you are referring to TDA2x platform.
