Hi @Muthyam ,
Can you share the datasheet of the display that you are trying to use?
Is it the same display that you mentioned on your different post.
Also, you main concern was to test whether you are able to see changes using overlays and for that you took backlight as an example. Since backlight is working , now you want to try adjust other timing parameters like horizontal and vertical resolution, right?
So, do you mean when you use some other resolution like 960x1080, it is not getting reflected?
