I do like the benefits of being a repeat customer.

I get fantastic results using S & M Disc for basic adjustments then a cheap Display 2Lt meter coupled with Chromapure software on my laptop.

The Duo's grayscale is so easy to do as is the gamma and color gamut.

Good deal.

I amazed when these guys pop out $15k+ worth of gear.

Other perks to using a calibrator, that a meter does not give. Also, once the upfront calibration is done on a new tv, revisits are very cheap, considering meter recertification and such. It's a hobby for me, and my main tv get's left to the professional.

That reminds me has Ken Worked on the Duo yet? Love to get his impression.

He knows Ken and another guy at AB, so he's worked with the Duo and other stuff before. Gregg is the one that recommended the Duo to me, primariliy for its Gamma/Grayscale/CMS features.

Another guy I talk to on another forum has his own meter, and a calibrated Samsung 8500. He bought his Duo right after me and has been working with it. He said it's improved the calibration results and PQ.

Sorry my friend. Not trying to belittle the service you get from your Professional Calibrator.

Must admit my equipment is not the best you can buy but it still manages to verify that my great perceived PQ is technically accurate.

Ken, from AnchorBay told me, if my Display would accept 4:4:4, to send the 4:2:2 out of the BR player to the Duo, and let the Duo do it. Both methods are color interpolation, but if the Duo is gonna expect 4:2:2 in, it's best to reduce the conversions.

You may still have better results with 4:4:4 from your player if its is greater than 8 bit depth.

Whats wrong with us just setting all these to AUTO and let the player and the Duo sort it out by itself?

4:2:2 and 4:4:4 conversion does not change the bitdepth, nor will it make any diffence on a luma ramp. It only changes the color resolution. 4:2:2 and 4:4:4 can be served at the same bitdepths. Just like choosing a color space, you really need to go through all of the bitdepth choices as well and figure out which ones work best. e.g. Lets say you send 10-bit from the OPPO into a display. If the display does not work at 10-bit, it may round down, which may introduce banding. e.g. I feed an SP-A900B 10-bit (dithered) 4:4:4 from an OPPO BDP-83 to get the best results.

Can the Duo force 10 bit output using 4:2:2 out?

They are using the capability of the ABT2010, so the Duo could do the same thing.

More patterns need to be created to deal with bitdepth. Its on the to do list. Right now we are working on a lip sync pattern.

I discovered a problem with my set that was causing it to drift. I would set it correctly and within days, sometimes less, it would shift the grayscale and peak brightness. If I had used a pro-calibrator who was a of national reputation he would have come in cablibrated my set, took my money, and he would have been down the road. Now if he was local be might have come back half a dozen times for nothing (assuming he was a really nice guy) and figured out the problem.... yeah fat chance. It just was not obvious and I can't even imagine trying to get the maker's customer service to do anything positive about it.

I have been messing around for months going through one Duo beta after another recalibrating my set anyway.. but the problem with my set is probably either a hardware problem, a bug, or an undocumted feature. It literally turns down the brightness apparently when it gets to a certain temp on the lamp. How did I figure it out.. well you know what you get when you don't get what you want... in my case lots of trial and error experience.

So while thank goodness for great pro-calibrators, unless they are local they have some limitations on what they can achieve if there are gotchas. The nice thing about a Duo, is with a decent meter and some persistence you can achieve over time, what a pro can not always achieve, they just can't make that kind of investment of time in your set. I have to give some of the great ones credit, day after day, they have to be able to wade into a deep pile somehow and turn it into a silk purse. In my case the efforts of a traveling pro no matter how brilliant would have resulted in a Cinderella effect. After midnight it was all going to turn back into the pumpkin.

The Duo still has warts, but for the money it is an awesome piece. I would buy a couple more of them if I had a few extra bucks around. I have a couple of Panasonics that simply don't have any real adjustability. One gets used as a PC monitor so... it's not important right now, and the other just doesn't get a lot of use. Still when they (Anchor Bay) do the 3 hdmi port "Lite" version for $499, I will stick one on every display I own.

After coming back from the Spectracal Pro Seminar, and impressed with the Auto Calibration features of the Iscan Duo and Calman 4, I was looking forward to this new feature for calibrating. Disappointment! No Auto Calibration Feature, and still the famous Yellow Tinge, despite the Colour Gamut nailing almost Dead Centre every aspect except the Green, which was a tad out. I'm now going to assume, if you don't have the lot more expensive Pro Licence, the Duo is dead in the Water as far as the Auto Calibrating goes. I also, I assume, I misunderstood the fact that I thought we were calibrating the Duo, not still cailbrating the actual set. So where am I ahead with the Duo for the monies put out for it. Set the Output to RGB and enabled the 1:1 which I seem to remember someone mentioning. Other than the Duo has 8 HDMI inputs, to me, right now, it appears to be an expensive Switch! Also missing the Pluge for Brightness and the Contrast patterns I saw at the Seminar. Are these also Pro Licence related, or have the Patterns been changed to patterns that are harder to setup? Also had a problem with the Blue Filter Colour Mode set - adjusted from Top to Bottom and never saw a change! I get a better setup with the LG's Picture Wizard doing the Colour, Brightness, Contrast and Tint setups!

How would you get 20 bit off 3 channels, or is that something more to do with 4:2:2?

Edit: Would that be 4:2:2 10:5:5, for 20? So no rounding would be needed between the Duo and BD85 at 4:2:2 20 bit?
