So if I set the EDGE to RGB and I still get a picture on the TV that should be fine?RGB is recommended though since the native dynamic range for videogames is 0-255 while all YCbCr color spaces are limited to 16-235. The most important thing about is that your TV has to be set to the same color space. Some TVs will only accept RGB, others only YCbCr, others both, some automatically, others manually.
Thank you very much for explaining this. I will change the settings to you recomendations later
