When ever i watch a bluray movie in my PS3 I've noticed that either the contrast or brightness is being adjusted constantly. This only happens in certain movies though. It doesn't happen when I watch Speed Racer but it does when watching Interview with the Vampire and Iron Man 2. I've seen people with this problem on the this forums and others but still no fix came from them that helped me.
So far I've checked my PS3 to make sure that the RGB is limited (should this even matter since I'm outputing it in Y/Cr/etc. ?), Y/Cr/etc. super white is on, and that Y/Cr/etc. is on in the BD output settings. I've also checked on my Samsung T240HD that dynamic lighting setting is off as well as power saver.
I'm running a HDMI 1.3a cable from my PS3 to screen. I watch movies that are 1080p quality all the time on the same screen on my comp. So that leads me to believe that either the HDMI controller is bad, bad HDMI, bad firmwire (can't find any to update my monitor anyway), or bad playback settings on the PS3.
Any help would be appreciated.
P.S. Wasn't sure where to put this thread so I took a shot in the dark.
