I am using latest Gemini 2.90 on my new DM500Si with Alps tuner.

I have used many receivers before and was very disappointed by the picture quality on RGB and YUV on this receiver.

The picture is very blurry and soft compared to my other receivers.

What can be done in the receiver to fix this? is there any config file i can adjust for parameters?

It seems the white level is way off adjusted on this receiver and the contrast way up.
