I did this, and from what I can tell, the pic looks great and you maintain the deep black levels without the back light fluctuation. I think. I will know more tonight when it is dark in the living room. I have no clue what is at play here to make it do this, but it looks like it may be a small work around for something....i dunno.
I decided to experiment a bit with this idea. Right now my tv is in standard mode. I followed this suggestion, and enabled "game mode" under system>general. Since I hadn't adjusted any settings in that mode yet of course it needed work. I then proceeded to put in all the same exact settings that I had in standard mode. So now game mode enabled in standard mode has the same settings as game mode off.
Well it appears that the tv does not
auto-dim the screen with game mode enabled like it does in standard mode with game mode off. It's very obvious - with game mode off, and in standard mode, choose a signal that is mostly a black screen with a bit of text - for me I can just turn off the FiOS box because then the FiOS box sends a pure black screen with a small Verizon logo as a screensaver jumping around the screen. Now just hit "menu" on the tv remote - notice how dim the pop-up menu appears in standard mode - the blue menu box is quite dim when the screen is mostly black - much dimmer than when there's a normal image on screen with the menu. Now, enable game mode - instantly, the menu appears brighter - the way it should be, just like when there's a normal image in the background. For me, the FiOS logo and text immediately gets brighter in the background as well as the blue menu screen brightening, however, the black seems to remain just as black as with game mode off
. Go ahead and switch back and forth between game mode on and off - it's an instant difference in the brightness of the tv menu - even though the black screen behind everything remains just as black either way. It's just as much of a difference with game mode enabled in standard mode as with game mode off in standard mode - both have the same nice deep black screen that is far deeper than movie mode.
So, by enabling game mode in standard mode, it appears you keep the same deep blacks, but without the auto-dimming that you see with credits, titles, etc.
Which leads me to believe then that the auto dimming in standard mode is not responsible for the nice deep blacks we are seeing, since those same deep blacks are seen in game mode under standard mode - and yet auto dimming seems to be disabled in game mode. So obviously something else must be responsible for the deep blacks in standard mode and standard mode with game mode on.Which then goes back to the question - why does movie mode have such poor black performance when compared to standard/game mode?
I'm not sure, however, that game mode is the ideal way to watch this set - perhaps others can offer their input here. What does game mode disable for image processing? Does game mode still use micro-dimming?
I notice that LED Motion Plus and Auto Motion Plus (AMP) are unavailable in game mode, which is unfortunate but obviously makes sense because it would kill framerate. Game mode may also be disabling other beneficial functions as well, to reduce game lag. Because of this, I don't think game mode is the ideal option, if there is an ideal option, even though it does seem to offer the deep blacks of standard mode while eliminating the auto-dimming. Perhaps I'm wrong though and maybe there is no reason not to use game mode after all. It just seems that maybe we're losing something good by using game mode - like micro-dimming maybe. It's a shame LED Motion Plus and Auto Motion Plus aren't available - which is why game mode doesn't seem ideal. Game mode is intended to disable all video processing - but does it disable micro-dimming?
This does seem very interesting though because I really think that this suggests that movie mode should indeed have much darker blacks than we are seeing. If game mode under standard mode can display deep blacks with no auto-dimming, then why can't movie mode? It's not because movie mode disables auto-dimming because it's disabled in game mode too.
Does anybody here know if watching in game mode would be inadvisable due to loss of beneficial processing that is disabled? Give this test a try - I'd like to hear others' thoughts on this as well. It really seems to me that game mode shouldn't have deeper blacks than movie mode, but it does. And both modes disable auto-dimming. I really think movie mode should be displaying similar deep blacks as these modes, but for some reason it isn't. And - since auto dimming is disabled in game mode, why can't we disable it in standard mode?
It seems right now there is no ideal mode for viewing - game mode seems promising but seems silly to watch blu-rays in game mode, yet standard looks great but with stupid auto dimming, and movie mode has yucky blacks. You can't win.
Here's what Samsung says about LED Motion Plus:To help negate the problem of motion blur on LED TV's caused by various things such as:
Pixel response time
Sample and Hold time
Slow camera shutter speeds
Samsung developed LED Motion Plus to help eliminate this blur. When this feature is on it will cause the LED backlight to strobe. This strobing mimics the strobing found in CRT (Cathode Ray Tube) televisions and greatly reduces the motion blur seen on the TV.
This is unfortunately unavailable in game mode.
