Generally true of course. Just remember the High Power is a retro reflective screen, so it shoots light back at the source. The closer your eye level is to the PJ lens height, the higher the gain will be.

How does that work? By Retro reflective you mean the kind of beaded screen that used to be used, right? Or matte white, but in any case in the old days, right?

I have never seen a screen designed to fire right back to the projector no matter where it's positioned relative to the screen, so please enlighten me. My experience has always shown that in a front screen scenario screens bounce their light off to the viewer, and the angle at which that light hits the screen determines where the optimum viewing position will be for the viewer. If it fires straight on, straight across from the middle of the screen - not usually done in front pj scenarios - then you'll want to be seated right beside the projector. If its lens is parallel with the top of the screen and thus fires the center of the image down a bit in hitting the entire screen, your best position will be below the pj, not straight in front of it.

But I am always willing to learn something new!

Yes, the HP is essentially like the glass beaded screens of old but with much finer beads. I believe the finer beads allow for less texture / sparklies and possibly a wider viewing cone compared to the old glass bead screens, though it's been a while since I've researched those things.
The behavior you describe is normal for most screens except the HP.
post #784 of 838
So if your projector is level with the top of the screen and firing down to the center of the screen, the best viewing angle will still be back up at the projector itself? And not down below, where it can bounce straight off the screen and into your eyes?

That is correct.
The surface of the screen is covered with microscopic glass beads, this is the same technology as the green highway signs. When your head lights hit it just right, it shines right back at you and lights up like the sun.

So placing the projector at the ceiling is going to get 0 gain, for the old HP 2.8 that would be effectively .8, with the current crappyer version 2.4 it is about a gain of 1.
So a shelf mount just over the heads or head level or between the 2 center chairs will get you the max gain.. raise projector or use ND filter if it is to bright.
Most people now use this screen to have a huge scope screen that there projector could not really light up properly if it were not for the gain.

For more info on how an HP works, have a read here.. the new 2.4 just has multi sized smaller beads than the 2.8 that this tread is about.

http://www.avsforum.com/t/773065/high-power-a-review-part-1/0_100

Here is what the surface looks like .. I got luck and when I purchased my first HP 2.8 then sent me the new 2.4 which did not look exactly like Tryg explains in the 2.8 thread.. so the research started..
My pictures of 2.8 vrs 2.4 The sample is the 2.8 the screen is 2.4

Post in the location thread in the signature area at the bottom of my post. If you also want audio, mention that too.

I know two calibrators that do both audio and video calibrations. You can contact both of them to find out if they tour your area.

I've used Gregg Loewen of Lion AV for the past 12 years or so. He started on my old Sony CRT and worked miracles from there. He helped me build my current theater set up, which I have used for years and while I was reviewing for another site. Gregg recently did my new Panasonic ZT 60. Gregg is ISF certified, but has been working as one of THX's main calibrators, teaching new calibrators to become THX certified as well. Highly recommended! Gregg works the east coast regularly, but also makes trips out west around CES and maybe during the summer.

Here's a link to his THX class Facebook page: http://www.facebook.com/group.php?gid=405940913568

Gregg Loewen of Lion AV has been doing my calibrations for years and when done my panels and rpt sing an awesome tune(picture)!!! He is the best!!! biggrin.gif

He is scheduled to calibrate my Sony VW1000ES in October but now that they have announced the upgrade package that will be coming in November I guess
I will have to wait a bit longer.

And by then the Sony 4K 65X850A I have on order will be hung by the chimney with care so he will be able to do both at the same time!!

Believe it or not he can make a panel that looks great out of the box look so much better with his calibration skills that I have always been amazed
and always keep coming back for more.

I can hardly wait to see what he can do to the Sony 4K projector and 65" panel!!

Had Gregg Loewen, when he was out for CEDIA in Denver in September 2013, calibrate my Panasonic 60VT60, Samsung 46B8500 and Panasonic 50ST30. He showed up at my house at 9:30 (30 minutes earlier than was planned at 10 am, so I do appreciate him for promptness) and was at my house for about 4 hours to do the three sets. The Panasonic 50ST30 I couldn't ever get quite looking right using the suggested calibration settings on avsforum settings and using the Disney WOW disc, colors were always just a bit off from what they should be. Once Gregg finished that set, the set looks so much better and was definitely worth the calibration. The 60VT60 and 46B8500 both had excellent pictures, but once Gregg finished those sets they both look spectacular now, especially 60VT60 which I can understand why CNET ranked it as one of the best TV's you can purchase for PQ. He was extremely informative calibrating the sets, he calibrated my 46B8500 first and explained all the settings he was doing and explained how things should look and why things look they way they are supposed to, and also showed me the before and after settings so I could see on paper the differences of what he performed(which he later emailed me the settings). Understanding how much the equipment is that he uses, pretty much justifies the price of his service. He next calibrated the 60VT60 and 50ST30 he was able to do those much quicker since he explained what he was doing with the 1st set and didn't need to repeat those. I would suggest if you are looking to get your TV's calibrated to look the best they can to use Gregg's service if he is going to be in the area since his expertise and knowledge and great customer service definitely made this an A+ experience.smile.gifsmile.gifsmile.gifsmile.gifsmile.gifsmile.gif

GM here.
Bought a new Panasonic P50ST60 Plasma several months ago and burned it in for 100+ hours using mixed programming (Movies, Sports, TV).
Now, just to set the stage. I am an Aeronautics Engineer (yes, I AM a rocket scientist..sort of anyway).
I understand hydraulic, mechanical and electronics equipment, computers and complex systems composed of these.
I debated with myself for some time about the 'need' to have professional calibration. After all, I can learn this stuff. I can learn about Luminance, Chroma, Y′CbCr vs RGB, right?
I have tried to do my own calibration and in fact did some calibration of my new Plasma myself.
It looked pretty darn good, using Cinema mode as a starting point.
However, I am enough of an engineer to know that if you really want the best job done, you find an SME (Subject Matter Expert) and hire them.

So, I contacted ChadB and settled on a date and time for him to come by and perform a calibration of my new Panny.
He was prompt, polite and asked me various questions about my viewing habits, room lighting, audio choices, etc.
He setup and spent the next 4 hours with me on this Plasma.
He explained things as he went and never seemed to lose patience with my questions (I ask a LOT of questions). He paid particular attention to some new tools he has
for setting up the display to give natural looking skin tones. VERY effective.
He performed a TV calibration first, then did 3D and my Panasonic 3D Blu-Ray player.

My final opinion?
HIRE THIS MAN!

The difference between what my 'settings' were and the final result from ChadB were nothing short of astonishing!
The quality of the images, from Blu-Ray, DISH TV (even SD) is truly impressive.
And I don't mean impressive like in a Showroom, where everything SHOUTS at you.
The skin tones of the actors are absolutely spot on.
The quality of the image does seem to be 3D without ANY 3D turned on at all!
Oh and BTW, I know actually enjoy using the 3D features of this TV. They no longer look 'unreal' or fake to me.
I am sold on professional calibration, if done properly. And ChadB KNOWS what he is doing!

Only downside?
Now, I must get all my other TV's calibrated, since they look positively sad in comparison with this one!

Thanks, Chad!!

Had Gregg Loewen over last night to calibrate my Panasonic 60ST60 plasma and he did an awesome job, would certainly recommend him to anyone looking for a calibration!

I was suprised at how much brighter and life-like the picture was post-calibration (the ftl increased from 29 to 35 I believe). Also suprised to see how much better cable TV looks, especially given the signal quality variance from station to station. NFL Footabll looked amazing. Blu-Rays now look 3D and skin tones are dead on.

The calibration took between 1.5-2 hours, and he took the time to explain each step. Very cool to see how the adjustments are done, and to see the various measurements updating in real time on the laptop. All in all it was a great learning experience and well worth the money, I will definitely have him back in a year or so to touch up the set.

Home this review helps, anyone on the east coast/I95 corridor (also think he mentioned he goes out to southern California once a year) don't hesitate to reach out to Gregg, he did a great job!

I'm only able to include links to owners reports that I find in the threads that I read. If any of you that run across comments from an owner who has had a display professionally calibrated give me a PM heads up I will be grateful. biggrin.gif
post #800 of 838

Just wanted to give a "shout-out" to Mr. Bob regarding the quality, assistance, and professionalism of his services offered. I have a 2003 Pioneer Elite Pro530HD and I was seriously considering dumping it for a new flat screen LED set. I've been "shopping" for about a year as my set picture quality had degraded to the point that it had lost its "wow factor". However, after my neighbor bought a new Samsung 7000 series and I saw it in action, I kept thinking that my set performed better when it was new. So i started researching ways to refurb it, and found this forum. I'm so glad I did.

 

I contacted Mr. Bob and used his phone-assistance to guide me through a deep cleaning of the lenses and mirror (10 surfaces), plus all convergence adjustments, and WOW...I'm stunned by the improvement!!! I now have a "like-new" picture that leaves me thoroughly impressed every time I turn it on. It definitely has the wow-factor picture that betters many of the new flat panels IMO.

 

Mr. Bob has a detailed and precise process for bringing back the "like-new" quality of these RP CRT sets, and I highly recommend contacting him before you make the switch away from your unit. My wife thought I was nuts to try this rather than just buy a new unit, but now she is amazed at the result (and thrilled that I didn't dump $2000+ on a new TV).

 

Thank you so much to Bob for his expert services.

 

Jeff

Unfortunately, that's the unavoidable downside to getting one of the best to come to your house. With travel and lodging expenses as high as they are, plus having to get our own health care and software / equipment, I don't think any of us are getting rich. tongue.gif However, we do our best to make it worth it for our customers, as many enthusiasts have confirmed here. The difference between the results we get and that of a GS or bargain calibration can be staggering.

Are you referring to Gregg's classes or his in-home calibrations done on tour where the travel expenses are shared among several customers? The latter seems very reasonable to me, especially for those who have a large investment in home theater rooms and/or gear. smile.gif

$1000 for calibration is reasonable ok sure
That's not a typical charge, but I've never used Gregg's service. Do you know how much of that is travel? I've used UMR and D-Nice and including their tour travel cost it was $400 until D-Nice reduced his video calibration price to $300 recently. UMR does high end audio calibrating too, which will increase his overall charge. I don't know if Gregg does audio. He, or his customers, have never mentioned it.

By "our" are you referring to information you've received from Gregg and his associates? If so, it seems that they may concentrate on high end home theaters similar to the pictures you have posted. If those are fees you've paid for audio/video calibrations, then they seem reasonable to me if the calibrators delivered good results on home theaters like yours..

Those prices wouldn't be reasonable for our living room's 60" Kuro with a 5.1 audio setup powered by a Denon AVR. redface.gif

I just did a scan of the front projector customer reports (Post 1), and flat panel customer reports (Post 2) and Gregg's customers seem to be in a range of displays that are typical for the $300 - $450 range that's been common for some time. I never see the posts for high end home theaters because most of the posts are ones that I read in the threads that are consistent with my interests. Even so, I've read way more posts than would be healthy for anyone. wink.gif

WSE, what is your angle / axe to grind? Please be straight forward or stop your whining.

My rates are on my website and have not changed for a decade. Usually $ 50 travel, and $ 400 for a display calibration. Extra work involving external video processors is extra. My day rate is $1100.

I also do audio calibrations and have taught the THX HT classes. While I know audio extremely well I do not consider it my forte. In relation to audio I can assist 95 % of the population at a very reasonable cost. If I can not assist a person to audio perfection I will make a recommendation to an appropriate acoustical engineer.

For video I carry with me and use: PR 670 ($24000), JETI 1201 ($7500), K10 ($7000), QD780A ($6500), Accupel 5000 ($1700). In addition to 3 laptops, cabling, and test discs. I have been performing calibration, consulting, and video educational services well more than a decade.

For audio I carry with me and use: Sencore 495, (w 4 mic multiplexer) ($4000), Ipad with ipro kit ($3500), laser distance measuring tools, spl tools, etc etc.

Considering the amount of money that most of my clients have invested in their systems, and also that the clients value hearing and viewing the best possible images and sound (within their limited time schedules) my pricing is extremely reasonable.

IMO and FWIW,

Gregg Loewen
post #806 of 838
Gregg's display calibration fee is in line with what everyone else charges, and yearly touchups are discounted, like every other calibrator.

I dont think its fair to expect a pro calibrator to roll audio calibration or dealing with lumagen work into that fee. These are time consuming and these guys have expensive gear.

For some people, it is all about the "bling" and not about the performance. In my best guestimate, about 50% of overall performance is due to the room and proper setup and not with gear cost.

WOW!!!!!
My guess is that it really is not too expensive for you...but you put little to no value in calibration work.
I am only saying this cause I looked at your setup..and with a very quick overview of your room...there is easily over $50K worth of gear there..with B&W speakers and Classe Gear.

A reminder from the calibration "sticky" threads:

"It has been my observation that there is a flaw in human nature that shows up in some folks periodically. That flaw is revealed when facts are ignored when they conflict with preconceived, misbegotten opinions, or threaten a self-serving agenda. Our culture has spawned many attitudes of resentment toward a product or service that costs more than certain individuals can afford or find worthy of the expense. Rather than accepting that they simply have different priorities, or admiring the quality or benefits of said product or service, and working constructively toward acquiring the means to procure it, some types of personalities default to immature resentment and unwarranted criticism. Crybabies are difficult to ignore, but they sometimes persist until they get some attention. Every public forum must tolerate such behavior, up to a point. The reasonable and rational majority will respond to logic and authoritative facts."

"Value" is strictly subjective, and differs from one individual to another. Opinion regarding value is only valid for the person expressing that opinion. There remains about six billion other opinions in this world that may or may not have a differing perspective. The issue of pricing and value pertaining to calibration services is a relatively ancient and tediously redundant topic throughout many sections of this forum.

This thread is important in that it offers first hand analysis and observation, from actual recipients of various calibration services, performed on specifically identified display systems, over many years. It remains one of the best places I know to refer people to who want understanding about such services. I am personally and professionally grateful for all the constructive contributors.
