I just noticed this. I don't know if it has always been like this. I just happened to be swapping between tuner 1 and tuner 2 and there is a subtle but definitely noticeable difference in the detail between the two tuners. I don't know how to tell which tuner is currently displaying but is there supposed to be a difference? There doesn't seem to be a way to intentionally set the resolution differently for the two tuners. Anybody seen this or have any ideas?
