hello guys.

So nowadays what do you think that offers the best gameplay and graphics, 720p or 1080p... what are you playing with?

hi
this has been discussed a lot when the game came out, and many won't agree with what i am gonna say, but i have tested a lot of different settings and here is what works best for me on a 42" Full HD TV:

-RGB Full range: Full (my TV is compatible)
-Output 1080p
-In game Brightness almost to max (the backlight on the TV is set a little less than half for energy saving / durability of the TV reasons)

Hope this helps

what if my tv is a20 inch lcd?

the size of the screen doesn't matter
what matters are the specifications of the TV
for the 720p or 1080p the PS3 should display the correct resolution if you set it up correctly and i suggest you leave the default setting
for the RGB Full range, you need to test it to see if your TV is compatible or not
if you google RGB Full range PS3 you'll find a lot of forums discussing the subject and giving examples of how to know if your TV is compatible
