So I'm not sure how many people care about this, but it was something I really wanted to see when I was researching PDP's. I looked for hard numbers for quite a while, but for the most part, couldn't really find any and just had to go by anecdotal reports or one line blurbs from reviews (usually for foreign equivalent models that may or may not be the same). Anyways, I decided to try for some real measurements on a North American G10 and compared the methods (for accuracy) to an A650 LCD since it is a very heavily
tested display line
. I took about 15 pictures of each "Mode/Profile" that could potentially affect the lag (Game/PC/Standard/Etc). Basically, I just ran a timer on a laptop and cloned the output over HDMI. The lap top is running in its native 1366x768. I have no idea what the cloning is doing for output over the TV, seems to be placing it in a 1080p window as that's what the TV's "Info" bar says and it doesn't fill the screen. Several of the photos follow.Please PM me any links to other's tests so I can add them.

and even try it yourself
1 Frame = ~16msG10 Game Profile
Avg lag ~1 frame. Very rare transitions that suggested it could be as high as 2 frames. The above is the only one I got.G10 Standard Profile
(This mode has some motion interpolation/processing)
I didn't see any significant difference from the Game profile. Same goes for Custom and THX, but it was too redundant to post their pictures.To confirm relative accuracy and compare/contrast with other's finding, I've included my results for the Samsung A650 LCD:A650 HDMI2-PC Mode (LCD):
Avg. lag ~1 Frame, more frequent transitions that suggested as high as 2. This could just be a function of the LCD's PRT, not necessarily processing lag, I dunno.A650 Movie Mode
(AMP and all Enhancers OFF):
Avg. lag ~4. Several transitions suggesting it could be as high as 5.A650 Game Mode:
Avg. lag ~2-3 frames.
