@felonyr301, that's what I was thinking of doing. I usually have my backlight at 4 with Energy Saver off. Energy Saver on Low seems to lower the backlight ~2 notches, so I'm thinking of setting it to Low and upping it to 6.
Game mode is weird though. On primarily white internet pages, it actually looks dimmer than my settings, but for the most part, it looks brighter. This is exactly how Energy Saver on Auto acts on my HTPC. Turning Game mode on and flipping through channels, you can clearly see there's some kind of dynamic backlighting.
@Orta, as I said above, dynamic contrast doesn't dim white pages like Energy Saver mode on Auto does, and with Game mode on, it behaves just like Energy Saver Auto does.
I don't use PC mode, because not all games support 1080i/p, some are 720p only. Plus game mode with Energy Saver on Low doesn't look TOO bad. I don't really care how accurate the picture is when playing games.
