Average Reviews:
(More customer reviews)I've been an HDTV owner for six years and during that time, I've assisted about two dozen friends in their HDTV home theater setups.I've just upgraded to the Samsung LN52B750 and I couldn't be happier.For reference, I'm upgrading from a Samsung DLP and I own another Samsung LCD HDTV.
There's a lot that's misunderstood about this TV, so rather than the usual Pros and Cons, I'd like to share how I'm getting viewing value from this set.
First, if you're reading this, you're either already an LCD owner or have read about them - and have read about this new breed and if you're like I was, you're wondering what's what.
Color swirls - you never read about this, but if you've watched TV on an LCD set in the past, especially with standard def (SD) stations, you've seen it.The backgrounds look like compressed colors from jpg photo files.My earlier LCD HDTV (8ms response time) had it - this one simply does not.(I did have trouble watching compression artifacts in a movie from 1930 on TCM on this TV - but that movie was so hosed, I can't blame the TV only.)
Contrast - you've read by now that all LCD set makers lie about this.If you're confused and remember the old audio days, that works like this:You'd have a 35 watt RMS/channel amp (into 8 ohms).Some would lie and call it a 70 watt amp. Then lie some more and call it a 140 watt amp (how about 4 ohm speakers?).Then lie some more and refer to peak instead of RMS - and suddenly a 35 watt amp is legally lied about as a 200 watt amp.Now - I don't know the ins and outs of legal contrast lying, but I believe what I've read - it exists in this industry.This set is rated at a contrast of 150,000:1 - with every stretch of legal lying possible - the contrast on this set is amazing.I still cannot believe that it's an LCD.It's simply that good in terms of contrast.One plasma-owning friend insisted for a half hour that I was wrong, and had gotten a top line plasma.
Blur/response/lag - LCDs are noted for this weakness.Not this TV. Read on.
Quality of SD programs - some controversy exists.Not a problem on this TV.Read on.
240 Hz AMP - this is the most misunderstood feature I've read about on this TV.Nothing I've read in any review prepared me for what to expect.I was buying the TV partially for this feature, noting that depending upon whom you believe, you turn this feature on, off, on for movies but not sports, on for sports but not movies.
It's none of those on/off things.It's adjustable.Here are my simple recommendations based on my setup:
1.DirecTV.
I use a Dayton HDMI cable, also bought on Amazon (amazingly good cable - buy it), from my DirecTV HR20.I have the HR20 set up to display all resolutions in Native mode.The LN52B750 switches resolution so quickly that this is not a problem.Unlike earlier sets I've owned, the HDMI input on this TV accepts 480i, 480p, 720p, 1080i and 1080p - the HR20 outputs all of those on HDMI.In DirecTV circles, it's well-known to set your TV and your HR20 to the TV's native resolution and turn Native output off on the HR20.This is because the HR20 is purportedly better at 3:2 pulldown processing than the top of the line chipsets/firmware used only a few years ago, in that the pulldown is done between the steps of converting the satellite signal to TV frames - and my own experience agreed with that.
However, I offer this simple advice - set your HR20 output to Native, all resolutions, and set the B750's 240Hz processing to: Blur=5, Judder=3 - and you'll be exceptionally happy with the results from all program input.My Boston Legal reruns have never looked so good and they appear on some of the poorest-signal (highly compressed) stations in my lineup.So, with this setting, SD as well as satellite 720p and 1080i programs look great - not fake at all.(And all you have to do to see the controversy on this feature is to "turn it on" without customizing its adjustment - and wait for your eyes and stomach to turn.)
I played baseball as a kid - loved it.Still remember what a ball looks like going through the air.When you're at the right angle, you see a stobe of blur and clear, red stitches.With the Blur=5,Judder=3 adjustment, I have finally seen just that watching a dropping curve ball (720p source).Any higher or lower, the ball looks wrong - oh, yes, very exciting - but wrong.
So I strongly recommend this set for its 240 Hz processing - providing you are willing to change those two parameters slowly and study a lot of source material to dial in what's right.I contend that if you're a DirecTV HR20 owner, I've just given you the key to really great SD and HD viewing.
And don't fear about those great blurs being missed from movies that wanted it there - Harry Potter and The Goblet of Fire looked really great in that regard.
BTW - resolution switching on this set is FAST - you'll experience little or NO extra delay when switching resolutions.(Not true on my older HDTVs.)
2.HTPC (Home Theater PC)
I use a Mac mini.I know, people hate them, you pay too much for Macs, yadda, yadda, yadda.The Mac mini is THE correct form-factor for a HTPC.You can find duplicates of this form-factor - and directly comparable features - in the Windows world for **exactly** the same price as a Mac mini - so, 'nuff said on price.
But - so far as a I know, only the built-in Apple DVD Player plays movies at 24 frames/second.Last I checked (and this may have changed by now), all other software (Win) does playback at TV rates: 60 frames/sec, with progressive scanning, etc.
Now - I'm not explaining all of this to brag about Macs - this is all about Blu-Ray vs. DVDs.
The de-judder tech being targeted by the 240 Hz processing is all about reconciling Blu-Ray 24 fps (read: real theater) vs. 30/60 fps (read: TV signals).
I don't own a Blu-Ray player - my gut, after all of these years, is still telling me to wait for the right features and prices.
But, I do use a Mac mini for my HTPC and if you do - or are considering one - here is my recommendation (based on Leopard 10.5.7): set the DVD Player to Best Quality Deinterlacing, set the Mac Display preferences to 1920x1080 at 24 Hz (it's progressive by default), and feed that into your LN52B750 with the 240 Hz options set to Blur=5 or 6, Judder=6 or 7 - and your jaw will drop.If you have a copy of Moulin Rouge - use it as your reference for the settings.I particularly recommend noting that you'll actually see the dust kitties on the floor in the Tango Roxanne chapter (among other things) and also suggest that you'll really love the depth and details of the stars, lace and glitter in Your Song.
With those settings you'll not only get a great HTPC, but you'll get possibly the best standard DVD player you've ever owned.Before the LN52B750, it was very good - now it's really incredible.Ghost Dog and Moulin Rouge on DVD are now completely three dimensional (not exaggerated foreground fakey - actually 3-D looking) - I didn't even know that this sort of picture was possible from a DVD.
I think my setup shows how well this TV works with a 1080p/24 fps source - I can only imagine that Blu-ray looks even better.

3.Sound
People complain about the sound quality of the LN52B750.I don't know.I haven't used a TV for sound in 8 years.I don't wish to sound snobbish, but really - you're spending a boatload on your TV and input sources, why listen to TV speakers?
I don't go for surround sound.I'm an audio purest that prefers the highest fidelity stereo.To each his own, but if you're like me, here's the secret on that:route the optical audio out from the LN52B750 into the Mac mini, not from the DirecTV's optical port.This routing is surprisingly better.Use Rogue Amoeba's free LineIn software, set all buffers to default values except for output - use a buffer size of 2048 - convert the optical to copper stereo and pipe that into your stereo system.This is the best TV-to-stereo sound I've gotten in 8 years.
I'm using large electrostatic panels, driven by a 400 watt (peak)/channel amp and a 2 kW servo-controlled subwoofer.You hear sound from all over the room and the depth and spacial qualities are great. I recommend more money into a better stereo and less room wiring over surround sound, but that's just me.To each, his own.
4.Miscellaneous Adjustments
Next, some words on clouding, screen adjustment and glare.
Glare - I don't have any.Yeah - I can see some reflection in the screen at various times of the day.The picture quality is so deep - as is the contrast - that I don't even notice glare, if it is there.And the screen is neither glossy nor matte.It feels glossy, but is low-glare like matte, but sharp and clear like glossy.They're telling the truth on that improvement.
Clouding - let the set burn in for a few days before looking.This is great advice for any large LCD, by the way.Clouding - I don't have any.
Adjustments:Go. Very. Slow.I'd recommend not touching a thing for a full 24 hours of viewing.So far, I've turned down the backlight and the contrast and turned up the brightness.I'm not going to suggest numbers here, though - there are too many factors, such as your room, that will dictate what's right.I will say that out of the box, the contrast is too high, as is the backlight (but not the brightness) - so, as I said: Adjust. Each. Parameter. Slowly.You'll be pleased.
