For me the main benefit of LCD was the reduction in glare from a matte screen and now even that has been taken away on these new sets. So to me LCDs use less eelctricity and run cooler and that's about all they have on plasma. So what gives? Why is everyone buying this LCD instead of the PN5XA650?

Quote: Has anyone here that bought a 52A750 ever consider the 58A650 or 50A650 plasma? If so, why choose the 52A750 over the plasmas? Just curious because this thread has way more traffic and users leading me to think that more people are choosing the LCD over the plasma. It seems that most experts still say plasma is the superior technology but these threads have me questioning that logic. Am I missing something?

There is no one superior technology. The answer to why LCD's are being chosen by more people are numerous. The decline and ultimate demise of CRT and RPTV's have basically given the reigns over to plasma and LCD. Now, plasma has been losing OEMS over the years which hasn't helped them compete with LCD's. Also, more and more people are using their displays as an entertainment hub with a PC hooked up as well as XBOX/PS3 etc. This favors LCD because LCD is not phospor based. Plasma owners tend to be non gaming, non PC participents as far as using plasma as the monitor, they primarily are DVD/Blu-Ray, cable/sat users. "Experts" have always tended to be pro plasma because of the "less is better" theory meaning a more purer, less processed picture. In fact, many pure plasma owners will tell you 1080p is not needed...a 720p on a Pioneer or Panasonic will suffice.
But the "experts" are also realizing the gap is closing, expecially with the Samsungs. Samsung has addressed some LCD issues like motion blur and black levels head on. The "experts" have recognized this and have recently mentioned that the 650/750 series has comparable inky blacks to the Kuro. The problem with plasma is lumenence. They are around 2.5 which when shown next to an LCD in a retail store will differentiate the whites. The plasma in store will look murky and dull while the LCD looks bright and vibrant. This gap closes significantly at home, however, many buyers purchase on first impression so plasma loses. Since plasmas are phospor based, you need to be more aware of image retention. Burn-in is almost impossible to achieve nowadays, however, and i have fought tooth and nail with plasma owners about this, but IMO, a plasma dictates your viewing habits instead of the other way around. How does it do this? Well, you must break it in, you have to limit a station like CNN with tickers after a certain amount of time, or you have to limit the black bars on the screen etc. A TV is meant to be enjoyed not babied. The excess mental baggage may be hazardess to your health.
As far as price points, well, if you told me 2 years ago i could get a 52" LCD with all the bells and whistles and generally regarded as arguably the best of the best for less than Michael Jordan's jersey number, well, you know the rest.
I hope i answered some of your questions about why LCD's have taken over as the display of choice.

Yes they are just as likely on the 750 as the 650. They have the same panel and build quality.
post #4293 of 12492
P.s. I may have some flashlights, I think that is what they are called, on the right and left top cornors of my beautiful set.

Does anyone know if there is a way to correct that issue or adjust it (them) in some way to make them disappear or not be noticeble?

I am not talking about the "Halo Effect", I actually like that.

Thanks for the excellent response. This is my first HDTV and I do not have any bias one way or the other. I'm just reading a ton on these sets in these forums and trying to read as many expert reviews as possible. This goes a long way in helping me understand why one technology would be favored over the other in certain viewing situations. My main concern is with watching action movies and sports, especially football. How does the 52A750 handle sports programming? Are there any more issues with the triple ball effect? I thought 120hz was supposed to fix that but I've read that many critics don't think this does much. Perhaps the 4ms response time fixed this issue? If I can feel confident that sports will look good on this set with no blurring then I think I'd choose this set over the plasma because it seems more versatile as you mentioned below.

When I am watching mine in a dark room I put the backlight at 4. I see no flashlights. If you crank up the backlight you may see some light leak through. You will see that with any LCD.

I'm fairly sure no other 46" TV would do a noticeably better job though

Is the cable signal feeding straight into the TV, or is it being fitered against grunge in the signal through a UPS or surge protector? If the signal's not clean, would the grunge get "upconverted" also?

Plus, LCDs are manufactured in all the smaller sizes where plasma can't/won't go. I read this week that smaller screens (under 34" or so) outsell bigger ones. I, too, was concerned about having to baby a plasma, as my viewing preferences may favor LCD. I still have a couple of plasmas on my short list, though, and that list includes the 650 plasma and 750 LCD.

Good points. Here are few more:
1) Price difference. Same size Pioneer Kuro vs. a Samsung 750. What a ridiculous price difference?
2) plasmas are noisier - both in their pictures S/N ratio and audible power supply buzz
3) Plasmas are even more un-green than LCDs
4) more expensive larger plasmas drop in brightness as compared to the smaller one: this is ass backwards
5) The American reviewers for reasons unknown (but we can speculate) were heavenly biased toward plasma. Think of a home theater type of magazine. Now consumers voted have with their pocketbook and voted them dead wrong. Poor lack of leadership. The British reviews were considerably more even-handed.
6) LCDs perform much better even with considerable and everyday levels of household ambient light.

I agree new technology should be convenient and not rule our lives. If you want to suffer then buy a Blu-ray player or Onyko receiver (without an Ethernet update port) to go along with your plasma. Oh and a first generation i-phone!

Here is what Consumer Reports thinks of the Samsung 650:
"Highs
Excellent picture quality across the board, with top-notch detail that makes the most of HD programming. Has very good color accuracy and better than average black levels. Contrast was very good, giving images depth and dimension. Excellent reproduction of scenes with subtly shaded light-to-dark areas. Excellent film-mode operation effectively eliminates jagged edges--"jaggies"-- on movie content. Has 120Hz technology that doubles the frame rate to reduce motion blur. The remote control is very easy to use; its backlit buttons make them easy to see in the dark. On-screen menu is very easy to navigate.

Lows
Viewing angle was somewhat limited, so the picture lost some color, contrast, or brightness as we moved away from the center of the screen. Touch-sensitive controls on console are poorly labeled and difficult to read.

Bottom Line
This 52-inch 1080p model from Samsung is one of the best TVs we've ever tested. It has excellent picture quality across the board, and was one of the few tested models with excellent sound."

In conclusion at least Consumer Reports got it right!

I have mine at 3, hmm I could have sworn someone on here said something about loosening some screws on the back of the set some place would loosen pressure causing them to vanish... or maybe I'm mixing up info or sets as I also go to 64U Sharps' page as well.

So far I feel the blacks are amazing but lack detail somewhat, is it just me?
I'm using Zerog6's Movie calibration & studdad's Standard calibration which are solid for the most part.

I watched the NBA finals OTA and they looked absolutely incredible. I didn't notice any TBE or motion blur. With a good HD feed my set has been great for sports.

I think loosening the screws on the back to reduce flashlights has been suggested since last year with 61/65 models. And as far as I remember, it has also discussed in Sony and Toshiba threads.

i just got my tv and my goodness this is the most amazing tv ever....nothing beats it....

I haven't even calibrated it...

anybody know how long lcd's are supposed to last? do they have half-lifes where the brightness dies after a few years?

Try these settings and see how it looks then.

http://www.avsforum.com/avs-vb/showp...&postcount=304

On an average, it should last at least 12 years, depending on the usage, and no, it won't get dim after a few years.

thanks i am looking forward to trying zerog's settings i've heard amazing things about it...i'm just wondering if doing the service menu tweaks would be worth voiding my warranty...i could just get my own insurance through ebay...since i know samsung covers you for either the first 30 days or first year i forget

If you go into the service menu and don't know what you are doing it there, you could end up with an expensive new brick. And yes, it would void your warranty. So, I would recommend you leave the service menu alone for now.

You would get 12-month warranty (or extra 3 months if you register it online but not sure if it is still going on) and if you purchased it with one of those major credit cards, your credit card company should give you an additional 12-month extended warranty so you end up with 24 months (or 27 if you get that additional 3 months from Samsung) warranty for free. Please check with your credit card company to make sure it has that option.

p.s. And if you used an American Express (not sure about VISA or MasterCard), you have 90 days accidental damage up to $1000.

There is no need to go into the service menu to calibrate the 750. Everything you need is available in the user menus.

Right? I figured as much, wish I could find that info again and or better someone drops science on how it works and how to do it if it has been confirmed as a positive and safe fix.

Regardless I'm no longer dying because this set is AMAZING. Can't believe I'm now someone who can write that without being a fraud, a fan boy or of limited LCD experience. Seriously, Banding lines no matter how faint can kill. At least someone like me with mild OCD, LOL.

Not a lot you can do. Some people have mentioned that they have faded over time, and my clouds have faded a bit. You can try lowering your backlight, turning down or upping brightness (I have heard both), lowering contrast (this works well with pillars and maybe it will help your flashlights). You might also want to see if dynamic contrast or black level adjust has any effect. When I had flashlights on the 71 tv, not much helped, although lowering the backlight did help some. I also had pillars, and lowering contrast helped with that.

Edit: oops, forgot about loosening the screws as was mentioned in the previous posts. Some people have had great success with that, but I have not looked to see where the screws are located on this set. Other people saw no difference. It must depend on whether or not the screws are tightened too much and putting pressure on the edges. Just be carefull not to loosen them too much or the damn thing may fall apart.

Could you folks comment on the 750's sd upconversion/upscaling capabilities? Presumably SD DVDs (with DVD player's upconversion/upscaling turned OFF) scaled to the 750's native resolution.

Also, I am lost in finding any good AVS links that talks about comparing SD upconversion/upscaling in HDTVs. It's all over the place.... :-(
Anyone care to share some good reads or comparisons links?

Also, is there a simple consistent method using a DVD to do this at a store? Which is a good movie title to test for upconversion/upscaling? i.e. what to look for?

Thanks in advance...

Hmm... Trying to give this some thought. I'm wondering if wear and tear from CEVA may cause the screen to be bumped around causing that flashlighting/clouding? Just as a matter of saying, I'm hoping for a perfect set here, but I'm wondering if most of these problems were from Amazon customers like me at all. Like the "you get what you pay for" bit where the best sets are from people that pay the full MSRP vs. the discount shoppers like us. Makes me even wonder if I'm even gonna luck out and get one that actually will be trouble free.
post #4312 of 12492
question that cloth they give to clean the screen do you guys actually spray water on it like the picture says??

i'm scared to even touch any part of the screen

Use the dry cloth that comes with the tv to clean the screen, wiping it off gently. Try using it dry.

I originally bought a 52a650 from Best Buy then ended up returning it for a 52a750 from Amazon. On the 650 I had minor clouding, on the 750 I have some minor flashlights...both were very minor. I would actually say my 650 from BB had worse screen uniformity. But again, both were very minor and I probably wouldn't have noticed except for reading this forum

How would transporting a tv from point A to point B have to do with flashlights and clouding? Those are more like manufacture defects, putting the thing together at the factory, Mexico. You make it would like majority of owners who bought it from amazon have some kind of defects with their set.

But if you are so concern about it, why not just pay a little more and buy it locally. I am sure the set is assemble in the back of the store when you order it instead of in Mexico, then transporting it to Samsung's warehouse, and then finally transporting it to your locally store.

Just got my 46A750 today. This TV is AWESOME.

1) SD channels of my Dishnet look very, very, very good. Better than my previous 27" JVC CRT.

2) I have a mini portable media player (mediashare) that I connected thru the USB port. It has an 80 Gb laptop hard drive formatted in FAT32. It plays my movies (.avi & mp4 files) FLAWLESSLY (touch wood). I believe there's no other TV that offers this feature currently. The best part is I don't need to use the remote control that came with the media player. Wiselink works just fine.

3) Now for the third feature. Streaming youtube videos from laptop to TV. I need some advice here. These are the things that I have now:

a) Laptop (Fujitsu Lifebook A3210)

b) Wireless router (Linksys WRT54G).

c) TV (46A750)

I read that I need to get a wireless bridge and hook it up to the TV using the ethernet port and install the software on my laptop. Is there any other setup that I need to do for the TV to see the files on my laptop ?

lol, +1. Clouding is caused during manufacturing, and shipping will have nothing to do with it.

Can someone more knowledgeable about 5.1 audio explain to me what it means on pg12 of the user manual? Under the heading Connecting A Digital Audio System it says

"When the source is a digital component such as a DVD and is connected to the TV via HDMI, only 2 channel sound will be heard from the Home Theater receiver. If you want to hear 5.1 channel audio, connect the DIGITAL AUDIO OUT (OPTICAL) jack on the DVD player or Cable/Satellite Box directly to an amplifier or Home Theater, not the TV"

If this is true why are there 4 HDMI inputs on the TV? These could only be used by someone who wants to hear 2 channel audio from all his sources. Apparently, the only way to hear 5 channels is by using an AVR to collect all you source inputs.

Is this typical for high-end HDTVs?
