That Fry's ad is actually for this tv... http://www.amazon.com/Mitsubishi-WD-.../dp/B003HPB97I not the 80" Sharp.

Jason

Exactly. Good catch Jason. "Actual screen size 82"

Also, it says it is a 3D TV and the 80" Sharp is not 3D........Nobody could sell the Sharp for $1,500, they would lose money............

We can dream though!

Sorry, techjunky2, I must disagree. Because of the shear size of this screen, some rolloff of picture quality can be seen at relatively small angles from close viewing distances. My eyes are not the most acute, but at 3' off-center at 10' away I can see a slight decrease of contrast and saturation at the opposite side of the screen. It is minimal and not bothersome to me, but it's there. I watch my set from a bit over 13' away and at that distance that rolloff is gone.

Active Contrast being enabled will improve off angle viewing in most cases. It also changes the Gamma from being mostly flat to more of an S shaped curve so for those with accurate calibrations in place it will alter those.

Jason

Fit tester, i sit in the middle of my 12'6" living room and when i shift all the way to the left or right walls i notice no difference at all in off angle viewing from 13' away from the display. I really dont know how you could see what youre seeing, but hey im not going to argue it, i just dont see it. I definately think around 13' is the ideal viewing distance. Although i have sat 5' off center at a distance of around 8' and the pic still looked exceptional. So i guess we agree to disagre...but i love this tv!

I saw what I saw because, as I said in my post, I was "3' off-center at 10' away", not 13'. I totally agree that from 13' away and 6' off-center there is no drop off of picture quality, at least not that I can detect. But at 10' it's a different story.
What I disagreed with in your previous post was your comment that "the tv is so large that off angle viewing would have to be extreme to diminish pq". With a TV this large, that's the case only if your viewing distance is also large...and you did say you saw "virtually zero difference", not none.
Our resident ISF calibrator, Chad B., had this to say about the issue:
"Although Sharp specifies a 176x176 degree viewing angle, all that means is that you'll be able to see an image at that angle. I found that the 632U, like most LED LCDs, was very sensitive to viewing angle. With the picture paused, moving just slightly off center caused flesh tones to pale and contrast to weaken. At a 9' viewing distance, moving about 1.5' to the side caused a noticeable degradation. In fact, because of the sheer size of the screen, even if you sit dead center you may still see some side effects of off axis angles near the screen edges. I saw that the edges became just barely pale at a 9-10' distance, so color was just slightly richer in the middle of the screen than along the outer quarters of the screen. Sitting farther away will diminish or eliminate the effect, though that is not a very good compromise."

I just dont see it, sorry. While "the expert Chad" may have come to that conclusion, I really dont think its an issue thats worth any time. Why would anyone watch a tv from such an extreme anglr or sit so close that this effect was evident. All lcd based sets have the off angle viewing "issue", if you actually call it an issue. Some people just have to find fault in something even if its ridiculously irrelevant to 99% of people. I mean seriously, if you are that picky about a minute change in saturation or whatever it is thats said to be seen, by a plasma. Everyone knows thats one of the major differences betwen the two types of displays. Like i said, if you are a consumer thinking about buying this set, viewing angle is not an issue unless you plan on being in another room and watching from an extreme angle, but really, who does that?

I meant "buy" a plasma if this really concerns you. This is such an old topic that still has the exact same storyline as always. Viewing angles are better on Plasma. Is this really stiill a topic worth discussing? Nothings changed.

"Move along people, there is nothing to see here " L O L

Correct Slappy.....as far as the viewing angle topic is concerned, you're right, there's nothing to see here, or there. ;-)

L O L ..I can't see why it's an issue , if your room is Huge & you have multiple viewing angles from all over ..Like a barroom &/or pool hall style room . Then plasma, multiple plasma's .
Man caves this display is perfect !!!

The topic of viewing angle is an old one, but was being discussed because a fellow member, wmwilker, asked a legitimate question and we were caring and polite enough to give our personal opinions instead of saying, "Use the search feature, buddy." The fact that our opinions vary slightly doesn't make either one of us right or wrong, or the two of us enemies.

Thanks for all the replies.
I got the 632 this morning and man is it a beast. I got the gamut and 2 point calibrated as best I could and then hooked to my Radiance Mini and did a full CMS and grayscale cal. The picture is awesome but I need to tweak the red and magenta some more. I can't get less than a 4 DE in the red. I will have to pick dagamepimp and Chad B's brain to try to get it better.

For most of my viewing area the dropoff is not enough to worry about. If I have a larger crowd for football some will be SOL. Oh well.

Again thanks and I'll be more active in the thread instead of lurking all the time.

Glad to hear you like it, Mike. Yeah, the viewing angle is not too important if you watch from 11, 12 or more feet away. Chad B. said red hue has to go + against measurement. I'm using Suzook's calibration settings, http://www.avsforum.com/avs-vb/showt...3#post21668083, post 1174, with red hue at +8 and red saturation at -12 to get realistic flesh tones. Enjoy!

A RED delta of 4 is actually astounding for the 632's, I am assuming you used your outboard CMS in the Radiance as there is no way to obtain an 'accurate' delta that low on red with the internal controls. These sets have a Red delta range of 8 to about 12 from what I have seen, I would be thrilled with a 4.

Did you check your color gradation after calibration, make sure you are getting all distinct steps in Red.

Jason

I respectfully disagree. I routinely get the red dE 1994 around 2.5 after cal.

Well you've done way more of these than I have and you have reference gear so you are the one that would have the definitive answer. I have only done a few of them and have yet to see anything like what you are stating. I also talked to someone that could not get better than 7 without causing other issues.

My limited experience shows that making any drastic adjustment to red causes other issues, is this not your finding? And are you speaking only regarding the 80" or the 60" and 70" 632 series as well?

* Oh and are you consistently experiencing a higher Red dE than the other colors (primary and secondary)?

Thanks,
Jason

Hey there. Have any of you guys been using the netflix app with our tv? I use this app quite often. And it gives me trouble constantly. I dont know what it could be. Hoping you guys could help me out. I used to use the wii before i got this tv and never had an issue. My problem is intermittent. Id say 3 or 4 out of times i go to use netfix it will tell me that netlix didnt connect please exit or try again. If i click try again it will never link up. But if i exit sometimes by going back out it might. And if that doesent work what i do then is go into my settings of my network and put in my routers wep password again and that works instantly to connect me to netflix. And i have been doing this for about 2 months now with this problem. Now today my fix isnt working. When i click on netflix app it takes tv almost 20 to 30 seconds to respond that i even clicked on the netflix app. And it gives me the failed can log me in message.

Thanks for the replies guys.
I did a rough calibration in the 632 with the 2 point and gamut. This is the first time using controls like that. In the gamut I set ChromaPure to HSL and I'm assuming that's correct. If not PLEASE let me know. I could never get the red very close and never outside the reference point as I could dial it in with the Radiance. If either of you have any suggestions I would appreciate any advice. I will attach the calibration report and again would love suggestions.
I will probably be tweaking this for a while but I like the picture for the most part but this display shows every fault shown by the source.

FYI I'm using a i1 Display 3 Pro profiled with a recently calibrated i1 Pro.

Thanks again

Hmm, those results are strange.

I agree that the red cms sat and red cms value controls do unexpected things to the picture; they should be used sparingly, and it's a good idea to pause an image with skin tones and run the controls up and down to see how they (mis)behave.
However, even before I got the Jeti spectro, I got red dE's under 3 on the 632u measuring with the i1Pro. I'm not trying to knock you, I'm just genuinely puzzled why it's not close to that for you. I'm going to attach one of my 632u calibration reports here. I think it's my first 632, measured with the i1Pro, and it shows movie mode before and after cal. The red dE is below 3 even before cal. If you have your calibration report, I'd be interested to see it and maybe we could figure out what's wrong.

Would it make any difference that he is doing a cal on a 60 inch 632 vs sn 80. Users seem to indicate maybe the chip set used might be different between the two models thus causing the red anomalies?

Chad, I'm using Chromapure and in the gamut I used the HSL setting. Is this correct?

I only remember one 60" 632U well enough to comment on. On that one, by special request of the customer, I went in to the SM and calibrated the 6 point white balance/gamma adjustment (all Sharps I know of have this in the SM; it's just a real bear to deal with) so the customer could use Game mode instead of Movie mode, because he was still a little bothered by some motion processing in Movie mode.
Game had terrible gamma before cal, though. The only way to make it decent was in the SM.
Here's the cal report on it.

I'm somewhat new to ChromaPure, but I believe that's just a way of interpreting the data. That's the setting that makes most sense with these displays.

However, in a sunny room the plasma is a POS with washout and mirrored reflections on most and a huge NEGATIVE that far exceeds a nominal loss in viewing angle --- washout on a sunny day on plasma can be over 80% and the reflections are mirror like and were on that POS Panasonic I briefly owned. I'll take the negligle loss and agree with the other poster - I don't see the drop off at all on my LCD's at normal viewing distance - but I could barely see anything during the day on the Plasma - especially dark video games and movies in the daytime Plasma is a bed wetters TV BTW with urinated on whites also!

Thanks for that Chad, after looking it over the 80" is definitely a different animal. My 60" and one other are sitting about delta 8 pre-cal in Movie mode, I would love to have that pre-cal delta 3.

That 80" had 4 of 7 points on the CIE (mine... 0 of 7) and that average dE was crazy for out of the box... WOW! The average pre-cal dE on mine would be at least 3x that and I have seen pre/post from a couple other 632's that are much closer to mine than that 80" (none of them were 80's however, two other 60"s and one 70").

I'll refrain from making any calibration generalizations on the 80" 632 at this point, if they are all similar to that one they are indeed different from the other 632's (at least mine and the others I have seen info on) and it appears Sharp is spending a little more time on the 80" before it's out the door. This certainly coincides with people calling the 80" the better looking display vs the 70"... they seem to be coming much more accurate out of the box with factory pre-sets (so no wonder).

My Low CT in Movie mode is up close to 8000K out of the box and closer to 10,000K in Game mode (best Game gamma was about the same as what you found with that 60"... 1.9).

Hopefully I'll get a chance to CAL an 80" in the near future and I can see first hand.

I recently discovered some repeatability issues with my i1D3 so I am having it replaced tomorrow. I also have an i1Pro so it will be interesting to see if I get the same results with the replacement i1D3 (although even the i1Pro alone was telling me Red dE was 8+ out of the box).

At least your findings collaborate what I was stating in the settings thread regarding drastic Red setting alteration (I could improve my Red dE while creating image issues ).

Thanks again Chad, your expertise is greatly appreciated and please don't worry about 'knocking me', I am just an avid enthusiast/hobbyist (long time videophile) and appreciate civil constructive commentary from industry experts.

Quick question. Got that message that there is a update available so i tried to start the update through my connected wifi i get as far as 5%u and it fails. I try again it downloads for a few minutes and fails again. My signal strength is at maximum. All my settings are correct. I figured out my netflix problem finially and now i run into this. Maybe there is another way of getting the update to the tv like downloading it to a flash drive or something.
