The Video Output Format setting was overlooked in this video, and I discuss this setting in the updated article: bit.ly/PS3setup The Automatic default appears to behave properly, but I would recommend configuring this manually.
The BD/DVD Upscaler and how I use it, I usually turn it on to Normal. That way, it's more consistent with the aspect ratio. Besides, if I turn it off, then the 4:3 image would just be stretched all the way out to fill the screen.
Adoniram León For most TVs using an HDMI connection from the PS4, the auto detect feature should properly configure the console for optimal output. There may be TV related controls related to improving lag time (e.g. Game Mode), but an auto setup with the PS4 + the TV's Movie/Cinema picture preset is going to look very good.
