Both the DUO and your Com Port on the computer need to be at the same bit rate, partiy, stop bit etc. Once that is done CP can operate the DUO and use it as a signal generator and allowing you to do an auto-calibration. I hope you understand that the HDMI out on the DUO is the main conduit for your source devices to get their signal into your display. The DUO if allowed modifies the signal before it sends to your TV it does not actually calibrate your TV. It adjusts white and colors in the signal to compensate for your displays deviation from reference response tothe input signal.

Plasmas are trickier than other types

Thank you for the explanation.

Essentially by calibrating the DUO as you put it, you have calibrated your display. The variation between say a good Blue-Ray player and other devices should be minor. For example a current Panasonic BD player is known in its standard mode to put out a reference quality signal requiring no adjustment with zero color error. A cable set top box can't really be calibrated as each channel and scene varies. A broadcast like the evening news will vary from camera to camera.

I set the Sony Ruby's bright and contrast from Radiance XS pattern before starting anything.

I am using a X-Rite EyeOne Display 3 PRO, mode front projector off screen. Signal generator is Radiance XS, window, 100.
My meter was level vertically but at the 10 o'clock position horizontally with its shadow down and to the right. About 10-12" from screen.

I used the latest version of Chromapure, but apparently did not load advanced auto-calibration license. It was late so I started it anyway and left the room.
Room is quite reflective, definitely below par. But no other light source. Results in brief:



Next: import right license file. Then ??? Rerun? Change window to field in generator?
All suggestions and insults are appreciated. I freely acknowledge this is new territory for me.

If you have US english windows, you should be OK, but if no - mine is Slovak, you can set evry thing in regional settings to english, still chromapura has problems with decimal point. If excel reports works, then quick reports are not working... Really annoying...
Tom, you know about it (in this thread it is mentioned) maybe one year ago, but no progress to resolve ?

It had to be at 30 when normally it is at 37 to 42. Also, chromapure measures my gamma way to low compared to what the tv is set to. I have to set the tv to 2.6 to get anywhere near the 2.22, and even then all the ire point have to be cranked way up gamma-wise cause they're all way too bright. Now here's the annoying thing, once I've done all that, the graphs are all pretty, but the image with bluray or cable video is just visibly too dark... I trust the chromapure gamma reading, not the tv setting, bit it seems the abl is making it difficult. Any suggestions on how to tackle this? I got the best results in the past with small windows with an apl background, but I want to use my 125 color calibration and those patterns aren't available.

Except I didn't look at all the files that ended up on the MacBook. The correct and previewed report is here: CalibrationSummaryDetailed 1.pdf 2468k .pdf file

Prior to my current effort to calibrate, my adjustments have been TV by eye on outdoor scenes, S&M BR disk, and VE DVD. I have never been satisfied with reds. They just are not real world. I can adjust things to where reds are incadescent or reds are reasonable and all the other colors are washed out. Red is my primary motivation for doing calibration.

I did not think that it will work but it does. Primaries and secondaries can be adjusted to perfection at 100% saturation and near perfect from 25% to 75%. Better than most TVs. Luminance can be adjusted also, full gamma control from 0-255. The only thing that is not completed yet is multi-point WB. At this stage only a single parameter.

Videophiles are in luck if you have one of these phones.

Apps can never do it, you will need to root you phone and flash this kernel. Most Android phones have certain calibration capabilities, you just have to flash the ROM and kernel but never a full CMS. The only comparable model with iOS is iPhone5 and iPad4.
