Not local dimmed. Just more edge lit garbage.

Yep, glad I stayed with the 844 for my replacement.

Changing the output of the genie seems to have fixed the problem. I've read countless post about edge lit tvs being junk but I encourage everyone to check this tv out before making a decision because the picture quality of this set is absolutely amazing. I'm not a big fan of 3d either but this set really delivers here as well. One of my favorite features so far is the ability to serf the net, check email, etc. while watching tv side-by-side. Initially I thought I wouldn't use the feature but it's great. Can't wait for football season when I can pull up my fantasy sites while still watching the games.

I would love to see what picture/color settings others are using. Also if anyone could recommend a nice Bluetooth keyboard with built in mouse that would be great, I see quite a few on amazon but not sure yet which one to get.

Thanks for the help.

Got a 70le857 in at work today (best buy magnolia). Tv picture is not good. Uneven backlighting and horrible motion handing. Also it has a matte finish screen, so colors are muted and hazy. Played with the picture settings for awhile but no luck. Step backwards from last year IMO.

My LC-80LE857U was delivered yesterday. I did a quick set of "before" readings on it. These readings are taken with OPC off, in Movie mode, brightness at -2, contrasts at +30, back light at 0.

Color


Gamma


Luminance


Contrast


And a 4 second exposure of a black screen (making sure the back light stayed on). I'm not sure what to make of this.

I'm confused on one thing. I thought the 844 and 857 were both edge kit. Can someone explain this? The 844 is full backlit?

Also, hmm, scroll down near the bottom of this 844 thread. Seems this ghosting issue is happening to someone else and it looks similiar to the pics in this thread. Maybe you guys can help him?

The 844 is full arrary-Backlit, a superior technology but more expensive to make. Glad I got another 844 from Sharp as an exchange over the newer one.

I'm not sure you'll have nonuniformity issues like many of us have with the 847/845... your picture (with a 4 sec exposure) looks pretty even overall. do you have the AVSHD test patterns? I'd be interested to see a 10% or 20% gray full screen picture.

Here's an example of 847/845 non-uniformity:

LINK

the bright blog lower right towards the middle will show up in content (dark content, dark critical viewing). My set has a similar blob in the upper left. for 2.35:1 films you don't notice, but full screen stuff like walking dead you do...

General comment is your calibration looks pretty good...

Best, jeff

yes 844 is only Sharp model for 2012 with direct full backlit. Elite is another one.
60" and 70" are edge lit for 2012.
for 2013 60,70 and 80 are all edge.

You guys are great. One more question. On the 80" 120Hz Full Array LED™, 632U. What was main differences between that and the 844 besides 3d and 240? And is there a big difference in person. I'm looking to pull trigger soon.

I just post a similar issue on the 844 thread, and its during Batman that it really bothered me same as you (Skyfall was pretty bad as well), almost to the point of being unwatchable. Over there the consensus is that this is "normal" and needs the touch of a pro calibration to correct, yours looks alot more uniform as far as the hotspots go

Jeff, I appreciate your response. This is my first "large" edge lit set so I'm not sure what to expect. This 80" replaces a 70" 732. I find that the corners are easily visible on black screens (movie titles, for example) but I don't see anything in the actual picture yet. I used one of the really dark scenes in the 7th Harry Potter film to get Sharp to replace my 70" 732 for clouding. In that same scene, I can't see any issues with this set. The black screen visibility of the corners is annoying but also present to some degree on my edge-lit Samsung 46"

The calibration images I posted are the "before." I've done one pass now and I'll do another calibration run tonight and I expect to be in much better shape.

The requested images for 10 and 20 IRE are below.

I guess I am the exception to the general consensus as I am VERY happy with mine. I got it about a week ago and haven't noticed any of the issues mentioned above. Now keep in mind, im a regular joe and not an A/V expert, but from my point of view im happy I made the purchase.

With that said, I cant seem to find calibration instructions to optimize the picture. Can anyone point me in the right direction?

I plan to use a lower back light at night, given how bright this set is. So I expect this will make any corner issues invisible under most viewing conditions. This set is 50% than my 732 with similar settings.

Hello all. I'm getting ready to purchase an 80" Sharp.

My question is should I get the 857 series or the 844 series.
I can get the 844 for $1900 less than the new model.
Is the newer model worth $1900 more?
I'm going to have to buy the 3d glasses separate with the older model so I imagine that would cost about $100.
Also, what is the best model number of glasses to get for the 844?
So I would still be saving $1800 buying the older model.

Has anyone got the 80 inch 857 or been able to compare it to the 844?
Which has the best picture quality?
I don't really care about the thinkness of the older model because I'm not going to wall mount it.

Thanks in advance for your feedback!

all of the 857's are edge lit. the 844 is full array. edge lit will potentially give some nonuniformity issues. look above for some examples. To my eye the 857's look more uniform, but the pictures above using a 4 sec shutter might be misleading.

Best,
jeff

I went from the 70" 732 to the 80" 857. The 732 has very similar technology as the 844 (other than 3D). I can say the 857 is 50% brighter than my 732 but both are more than bright enough for a bright room. The back lit 844 might show some of the back light pattern on a blue sky or total black screen. In theory clouding is more likely in the 844. The 857 case is definitely more attractive (but that's not an issue for you).

This year's 3D glasses are blue tooth rather than IR. So the glasses stay synced with the set even if you aren't facing the TV.

For $1900 less, I'd suggest getting the 844. Unless you plan to go "pixel peeping" as they say in the camera forums, I doubt you would see a difference between the two sets.

I need to adjust the overscan as I'm seeing some pulsating white horizontal lines at the top of the screen at intermittent times (when there is CC data present in a show with the DirecTV genie).
Anyone know how to do this?

You are probably using dot by dot mode. Since this mode has no overscan, it will sometimes allow you to see stuff at the very edge of the screen that is supposed to be hidden.

I received my replacement 80" from sharp today. It is just as bad as my original with clouding and is pretty horrible in dark scenes. I'm not sure why Sharp can't get this right but it's definitely a problem with two of the sets I've owned. I've decided that I will just deal with it since there aren't really any other options in this size. I'll go back to adjusting the levels to see if I can reduce it as much as possible.
