LN52A750 Measurements and Viewing Evaluation
For calibration I'm using both the Sencore ColorPro5000 and Colormetre HCFR software. Basically, Sencore is great for calibrating your set but doesn't give you the pretty graphs that we like to show in our reviews. That's where Colormetre comes in. From the default settings, I measured:
Dynamic - 11000k (4850:1 contrast ratio)
Standard - 8500k (2300:1 contrast ratio)
Movie - 6500k (1450:1 contrast ratio)
Calibration options were nearly unlimited on the LN53A750 not that you needed them. All the standard stuff was there (Brightness, Contrast, Tint, etc) along with your gain and cut adjustments under the White Balance menu under Detailed Settings. I fiddled with these controls but in the end, I don't think you need to do much else other than turn the set on. I was able to achieve these measurements from the default Movie setting (Note: throw out any color readings below 30IRE due to limitations of the colorimeter I am using):

Comments on Audioholics DVD Torture Tests
The only change I made from
the default settings was to set Film Mode
under Picture Options to "Auto." Without this enabled, the unit
failed the Film Detail and all the Cadence tests including 2:3 pulldown when
fed an interlaced signal. The Samsung LN52A750 passed the HQV test with flying
colors. Feel free to set each of your components to interlaced output and let
the display do the work - unless you spent a lot of money on your source (or you
have a Blu-ray player), you aren't going to do much better than this display.
Viewing Evaluation
It is clear that the Samsung LN52A750 is providing a great deinterlacing as per the HQV tests. It is also clear that you the consumer needs to do little other than shell out the asking price to get that fantastic performance. But the real question is, "How does it look in real world applications?"
DVD: 300
300 is easily one of
my favorite movies to use in reviews. The picture quality is a little grainy
(by design) but there are tons of dark scenes, brown tones, and deep reds not
to mention a lot of action. I used this disk for a number of subjective
evaluations including dark definition. The Samsung LN52A750 showed all the
proper definition in the prodigious amount of darkness in this movie. Even
during the night scenes, you could pick out the detail in hair and backgrounds.
While Lionidas is climbing the hill to see the oracle, even through the smoke
and darkness, there is never any sense of loss of detail. Is it as good as a
high definition disc? No, of course not. But it is still very good and sure to
impress your friends.
Xbox 360: Army
of Two
With the recent update
of this game, Army
of Two has recently hit my play rotation again. For the purposes of this
review, however, I was looking at vibrancy of color, ability to handle fast
motion, and over all picture quality. Army of Two has some of the most stunning
graphics (in game or cut scene) that I've ever seen. The LN52A750 absolutely
shined through this portion of the review. The 4ms response time in conjunction
with the default setting of "Low" on the Auto Motion Plus 120Hz
setting made for a very clean and fluid image. While I played around with the
Auto Motion Plus setting a bit, I never really experienced that "too real"
phenomenon that people associate with it. Often, this is because real film
doesn't refresh that quickly. To me, it just looked gorgeous. All the
characters were rendered beautifully and the colors really popped. If it wasn't
for all the people shooting at you, you could get lost in the graphics of this
game. And don't even get me started on the lush cut scenes. Rarely is there a
game where I will voluntarily watch the cut scenes more than once. With Army of
Two, it is rare for me to skip them.

Even after looking over the original ln52a750 article Tom Andry wrote, it still seems like there are more settings for the picture and detailed settings. Can anybody do a list of what those are? Or does anyone have the exact calibration levels?
That would be up to your room and your display

What exactly is the "purple haze" issue? This is the first I have heard about that one.
Who the heck comes up with these names? LMAO
Purple Haze... it's something I kinda came up with on the fly.
It remined me of the TN panels; when the whole screen was black, you move your viewing position off center axis and the screen looked purple instead of black.
I think that either panel would have been a great choice; but the 750 is so close in price to the 650, I don't know why many would choose the 650.
That's just me though.
We actually read the whole thread prior to making the decision.

Thanks. He went with the 750 and ordered it from Amazon last night.
