post #601 of 1357
A bit ambiguous.
post #602 of 1357
On thread #132 there is a video clip regarding sharp will release the professional monitor in Q1 2013 with local dimming. I assuming this is the industrial monitor.

For those who currently own the 90". How is the black level without the local dimming? And how many of you calibrated the unit, is there a major differences?

I am planning on getting the 90" sometimes next week and have it calibrated by certified ISF technician and of course I will share the data but I need to clarify one thing though, is it necessary to wait for 100 hours of operation before the calibration.

I agree. I can't imagine that $99.95 would cover all sets above $1000, even those that retail for $10,999. It throws the whole underlying methodology of insurance into the ditch.

When I called SquareTrade some time ago there were different prices for sets of different retail value (and sets of different replacement value), as I posted.

I think calling SquareTrade directly would be more helpful. They might even better explain Costco's bundling of SquareTrade.

I offer that yes a 100 hours for a wait but really if you are going to do a calibration ,you really must have confidence that that's a display that has passed the trail period for failure but also if there are any minor issues that might show up . .
By that I mean make sure that it's period of breaking in has gone past the point that the display is not going to have a issue crop up . Most major failures are in the 1st 100 hours of use in modern electronic equipment but some issues do crop up months later . As once a calibration has been done you can't do a hard restart without losing the settings (& most are settings inside areas that a normal person can not reach ) , a hard restart is the 1st thing that any service rep is gonna do IF there is a problem issue .
Me , I would wait a good 3 months myself . but that just my Humble Opinion cool.gif

I agree. Wait if you can. Keep in mind the 90" does not have an ISF day or night mode to work with, like the Elite.

You may want to try some of the settings on this thread first and see what you think.

The black levels of the 90" is not as good as the Elite but close. But of course no set has the black levels of the Elite, maybe with the exception of the Panny VT50. Not sure about the Flagship Sony.

Thank you very much to all. I will wait after the 100 hours then.

dreaux,

If I understand you right, the elite has 2 modes but then how often you switch between the 2 modes (day & night). In Canada, we don't have the elite so I don't much about it.

I bought the Samsung ES9000 75", the color and black level are amazing but I returned it due to clouding issue, I wanted to give it a another chance but a fella from this forum (mata7) returned 3 ES9000 for the same clouding reason. I guess Samsung quality is not as high as I expected. I checked out the 90" at Trutone in Mississauga but I couldn't judge the PQ because of the multi feed from a Bell satellite TLC HD channel (1080i) to many TVs.

dreaux's screenshots (thanks for sharing), I find it is useful and it is really helping me with the decision.

Yeah the Elite has two ISF modes. One set to watch in day...with ambient light and night for watching in the dark. Not sure what mode you are going to have calibrated....maybe the movie mode.
All modes are accessible except 'dynamic fixed' mode.

So you bought the Samsung ES9000? I haven't seen it but I would have imagined it would be quite a picture. Didn't know about the clouding issue. It must have been quite noticeable to have returned it.

I think you are going to be quite happy with the Sharp 90". It has an excellent picture and very good blacks. I plan on posting some more pics with Suzooks settings tomorrow. Been too busy until now. I only use it when watching Blu-ray movies, not regular viewing.

Looking forward to your impressions when compared to the Samsung.

I am very happy with the PQ of the 90" and that's coming from an Elite. I have noticed that the PQ has gotten better with more hours on it.

I don't know where you live in Canada but in Montreal there are stores like Fillion and Brault&Martineau where one can get the Elite...
post #609 of 1357
Some new pics shot in the 'movie mode' with Suzooks settings. Blu-ray of Avitar from a Chambrdge Audio Azur 751 blu-ray player.

Again some banding seen but not to the naked eye. Seems no matter what shutter speed I use it still is there to some degree.

This is serious clouding you have there! eek.gif
post #613 of 1357
I am also curious to know how you'll feel about the Sharp 90 PQ vs the Samsung 75 PQ...

dreaux,

How do you project the light from your TV to wall behind the TV

Thanks again for sharing those pictures. It is better with Suzooks' calibration setting.

Seems that is a industry wide problem with these lager 55"+ displays .Sharp has twice now tried edge lighting & both times have had a huge failure rate.
The 70 inchers from Sharp are hit or miss on clouding with most all having some degree with clouding
it's really hard to get the alinement right with the edge LEDs on the larger panels consistently ,
they keep trying because it saves alot of $ . And they can still charge a higher price @ a lower MFGering cost .. mad.gif

It is not wall mounted, it is on a table stand. It's just a lamp. But I am thinking of getting some edge LED lighting, it does help with eye fatigue.

Other members have tried this with good results.

How does it improve colors? Not sure how it works. Read their description, isn't just a florescent bulb?

it's color balanced & has a "K" rating that is scientifically know to improve view . . . . They are way over priced IMO smile.gif
the LED strips with the color choices & dimmable work just as well . . . they are a fraction of the price
but I M H O these lights really only work well in a really dark dedicated HT room .

I myself don't like them I tried but for me the rear light behind the display or off to the sides drew my eye away from a full immersion effect

. . . . . . . . But that's just me , you might feel different
It's one of those you really like them Or you hate them rolleyes.gif
I actually like a low reflected light that is behind me but that doesn't reflect on the screen , doesn't cast shadows , my wall behind the display is a dark red Oak .
So it's really room dependent on how your room is , as if they will work for you .
It's best if you test lights out that you might have at home to see if you like the effect IE; lamps with a towel thrown over them behind or off to the side of the display
allota guys have bought these expensive ones just to find out they didn't like them .
the cheap LED ones are dimmable , have colors & a remote

Here is some fundamental truth regarding bias lighting:

What are the recommended elements of properly implemented bias lighting?

1. The color of light should be as close as possible to the video white point of 'CIE D65' (loosely referred to as 6500 Kelvins) for color video viewing .
2. The color rendering index (CRI) is often published for a given lamp. A minimum CRI of 90 out of 100 is recommended for color reference applications.
3. The illumination should originate from behind the frontal plane of the screen to avoid reflections, haze, and glare (which interfere with, contaminate, and obscure the image).
4. The lamp itself should not be directly visible to the viewer, but rather the illumination should be reflected by surrounding surfaces, such as the wall behind the monitor.
5. The brightness of the reflected illumination should be 10% or less of the brightest white the monitor is adjusted to (calibrated for a dark environment).
6. Surrounding surfaces within the observer's field of view of the monitor screen should be neutral in color (gray to white), see: Munsell Color Order System's neutral value scale.
7. Completely surrounding the monitor screen with illumination is not necessary to realize the principle benefits of the technique.
8. It usually works best for the lamp to be mounted on the back of the monitor or TV cabinet (rather than on the wall), in order for the illumination to spread out over some distance.
9. Test patterns for adjusting bias lighting relative to the monitor screen are available in many optical disc programs for setting up home entertainment systems (see: 'Avia II- Guide to Home Theater,' 'Digital Video Essentials' series, etc.).

What are the proven benefits of correctly implemented bias lighting?

1. Reduces or eliminates eye strain and viewing fatigue in dark viewing conditions.
2. Eliminates image contamination due to reflections, haze and glare on the screen from conventional room lighting.
3. Enhances perceived black levels, contrast ratio, and picture detail by enabling dark adapted viewing.
4. Preserves correct color perception of the video image by the viewer.
5. Prolongs monitor phosphor life by enabling dark room viewing and lowering of screen brightness requirements (phosphors are used in CRTs, plasmas, and LCDs with CCF or white LED back lighting).
6. Provides a low level of illum

Again, I have used the Ideal Lume bias lighting for years (mounted behind my 60" Pioneer KURO Elite) and it most definitely offers the benefits listed above.

You are right...they work best in a dark HT, which is where eye strain is most possible, thus the need for bias lighting.

Yeah they didn't work in my room as it a living room , I keep it dark due to a concussion syndrome injury that has me having a light sensitivity issue .
I have friends who swear by these & I have been in their HT , but for me Nah ! I didn't like the effect . I always liked the movie theaters dark when I was younger before the head injury
It's personal thing for sure , not saying they are bad at all . . biggrin.gif
I glad they work for you thou ! smile.gif !

Just a word on watching Netflix on the 90". Unlike my AVR which has Netflix, the Sharp 90" does HD 5.1 audio and even more importantly for me will do subtitles.
I use them mostly because I am half deaf and watch a lot of English series with accents that are hard understand. When watching Dowton Abbey or Forsyth Saga. I was always saying...what did he say? Now I use the subtitles.
With the Netflix button on the remote it is easy to get in and out of Netflix.

Lots of people have trouble with TV dialogue and British TV! If you listen to a 5.1 broadcast and don't have a great center channel it can easily get muffled. And British TV!!

We were watching Sherlock last night, and I and my girlfriend kept looking at each other and saying "What?" continually. Apropos of that, some years ago there was a comedy about crews that demolish buildings in London, and with the thick cockney (and other) accents, the American release (and possibly the British) had subtitles!

Anyway, glad you're happy with your set. You might be a very popular Thanksgiving spot, dreaux.

Happy Thanksgiving. to all.

A large sharp was featured on the Jimmy Fallon show. They were showing some games with the new wii. It looked really big, I thought it was a 90 but the frame was glossy like the 80. Unless they have a bigger model out there.
