Its not quiet true....because i had a friend he has a an old samsung LCD tv (fullhd) and hes screen unscaled the 720p games to 1080p...and the
games they showed terrible....
i mean the PS3 settings were 1080p....the game were 720p...and the screen has not gone down to 720p automatically.....and the picture were awful....
Maybe I have not made myself clear, let me re explain.
I have a modern HDTV FULL HD. with HDMI 1.4 ARC and I have a slim ps3 120gb
My tv and ps3 settings are set to full display settings i.e. the ps3 see's all resolution possible from 480p, 576p, 720p. 1080i, 1080p
I have games like Fifa 11 for example that:
If you leave all the above settings i.e. (full resolution display settings - automatic) the game will play in 720p (game native is 720p), now if you disable 720p from your display settings by maunally removing the 720p tick box, the game upscales to 1080p
Gt5 which runs at 1080p native, will run at 1080p on my tv without any settings needed to be adjusted manually like mentioned in the ''FIFA'' example.
Now in skyrim - if you leave the display settings to auto (all display res availavle 480p, 576p, 720p. 1080i, 1080p) the game will run in 720p, if you do the same step as in fifa by disabling 720p in order to make it upscale to 1080p the game will not upscale in this case and runs in 576p. same it does for other games like MGS4, PES2012 etc, few are the games that upscales.
NOW pleas note that i am refering to EU PS3 with EU GAMES and not USA versions etc, as if not mistaken on the american version on the box it states 1080i which on the EU version in states 720p
