yes, they come in different lengths, and you can also extend those by getting USB extension cable. The key is get one that works with your computer and OS. I heard Prolific chipset is good with DUO.

I have amplified 16 foot USB extention cables that work great! Similar to these: http://www.usbgear.com/USB2_extensio...ion-cable.html I use one for my Duo and one for my Display 3 Pro meter and Chromapure to control everything. I can sit in my theater chairs recline back and control my Duo in the projection room behind me and another cable to reach my Display 3 meter right in front of the screen.

Calman has a newer 4.6.3 update for those who calibrate using the iScan Duo. New software supports the new Panasonics 50 Series TVs.

Hi all I've contacted spectracal about buying my own kit. I'm sick of having to pay people to come out and calibrate. I was told to get this kit : CalMAN DIY Consumer AutoCal Package.

The question is once connected to DUO is it plug and play?

Yeah it's pretty straight forward. There are some YouTube videos on CALMAN and the duo you can watch. SJ

It's highly recommended that a manual calibration be done first, then fine tune with the Auto-Cal.
I've found my calibrations, out calibrated the Auto-cal, but then again, they're LG TVs and the whole calibration scenario seems geared to Sony's and Samsungs. Panasonic and Sharp have now been added, but despite LG being #2 in sales, Spectracal still doesn't support it! ChromaPure has added LG support, but I've now gone back to Calman to give me the best results. The iScan Duo is only providing my Patterns for the Calibration. The AVCHD is used for the Contrast, Brightness, Colour and Tint. S&M for Sharpness, and to confirm the Colour and Tint setting. (Have not checked out the New S&M yet. I definitely do not use the Disney WOW calibration Blu-ray)

If using the Duo for calibration I would recommend AutoCal for gray scale and then a manual touchup if needed. Manual only for color gamut if your points lie outside the triangle.

Thanks for the reply p5browne but unfortunately Im not educated enough in the field to understand in doing a manual calibration that why i get the services of calibrators. There goes the idea of sitting back and let the Duo do the work. Thanks for your reply.

Hi praz i was told by spectralcal to get the d.i.y. Package which was the autocal to my understanding. I've written them an email to give me an idea on how it will work with the Duo still waiting for a reply.

You will have the Duo interactive workflows in the downloaded version. However, you need to add an Autocal button:

I used the Autocal for greyscale only. Used manual/interactive for CMS. SJ

That seems to defeat the whole point of autocal, as well as implying that the result is indeterminate.

Also, I was surprised at your reference to support for specific displays.

No projectors? I have a JVC.

Similarly, why doesn't autocal put the points where they belong on the triangle?

Manual calibration, are we talking about calibrating the TV through its controls or through the Duo's? Apologies if that's a silly question, thread's a long read, and I've been trying to figure out what settings to keep my ST50 at prior to calibrating it with the Duo and a C6 rental that should be arriving tomorrow.

Would it still give me better results if I attempt a manual calibration first, considering I have no experience with CalMAN or calibration outside a simple Spyder3Elite?

Calibrate TV first, then calibrate via Duo.

IMHO auto-cal doesn't mean "Automatic Calibration", it means "Automated Calibration". Auto-cal doesn't do everything for you, it just speeds up the repetitive portions of the calibration process.

The actual TV is calibrated first. If anything goes wrong with the iScan Duo (like an accidental Reset, etc.) your TV is still left calibrated!
After a Manual Calibration of the TV:
The Auto-Cal calibration for my CMS was a disaster! And it looked that way!
The Auto-Cal Greyscale values were all higher than what I calibrated. (In other words - wasn't even on the 100 line, but above) And it didn't look so good either! Reset the iScan Duo - but still had my Original Manual Calibration. Now that I finally have the Service Menu White Balance manually set correctly, may give another try. But not being optimistic!

Seems I have more work cut out for me than I thought. Which I don't have a problem with, the appealing thing to me about autocal was, or at least everything I'd read seemed to imply it would be easier to get more accurate results as a novice calibrator.

I've started going backwards through this thread, but what I haven't seemed to be able to find much of yet is recommended usage of Mosquito NR, Fine Detail and Edge Enhancement. I realize it's possibly subjective and source-dependent, but, is there any? Or even, should they be used at all?

all?

I rarely use those, it is very much source dependent.
But occasionally with a cable 480i formatted video, the 480i Encore channels come to mind, there can be some improvement with edge enhancement on old westerns like Gunsmoke.
Mosquito noise can be an issue with Laserdiscs and I sometimes engage that when using the Pioneer CLD702 Laserdisc player.
But for the most part these features can be left off.

I have 10 sources connected to the Duo, including the CLD102 (composite video) and an S-VHS VCR (S-Video). Some old tapes can benefit.
My Tivo connected OTA receives UCSD analog NTSC broadcasts which can benefit from some sharpening.
But in most cases it is not worth the effort.

In the end, experiment. It is nice to have the option.

sorry, but no, it can't. There's is no mosquito noise on laserdiscs. Mosquito noise is a digital compression artefact caused by low bit rates in MPEG2/4 encodings.

There is an aspect ratio setting for the Duo's output, which define's aspect ratio of the display. However, I'm a bit confused by the Duo's input aspect settings. What exactly is the relationship between the "Picture" aspect ratio and "Active" aspect ratio? How do these interact and affect the displayed image?

Maybe a stupid question, but if I have a tv capable of displaying a 1080p 24Hz signal, why is it that when I set the video output to "auto" duo chooses 1080p 60Hz?

Is your source outputting at 1080P24?

You have to set under output frame 1x1 to enable even if you have output set to auto. I had the same issue until I discovered this. It is set to disable by default. It is somewhere in the manual.

No it is outputting 1080i. I just thought the duo could force it to 1080p 24Hz. I get 1080p 24 Hz from my blu ray. I guess it must depend on the source. Thanks.
