Treated myself to a ps3 today and i've hooked it up on my samsung lcd through HDMI. So i was looking through all the video options and came across a "RGB range" setting. This was defaulted as "Limited" but when i switched it to "Full" it seemed the colours improved a lot, more intense black for example. So my question is , can anyone explain me what the range does and does having this set to a "wrong" setting can it be harmful for my tv ? Thanks to any responds in advance.
