This is my method for calibrating my plasma. It started out as notes so I do not get lost in the middle of a calibration but it has grown to be quite comprehensive and might be considered to be a guide
but just for my particular set up and it is also missing some nice pictures. Please critic and correct me as needed.
Panasonic VT50 Euro Calibration
Laptop, DisplayPort to HDMI cable, HCFR 3.3.5, i1Display Pro (EODIS3, ID3, D3) and ControlCAL software by turbe
Enable the IFCC Professional modes on the TV and reset any settings in the Professional 1 mode including advanced settings. Switch to Professional 1 mode on HDMI1.
Connect the laptop to the HDMI1 input with the DisplayPort to HDMI cable and set Windows so the desktop extends on to the TV. The DisplayPort is most likely set to 0-255 full range and the TV will most likely detect this and set the picture to 0-255 full range.
Click [Start] > [Run] > dccw.exe and move the Display Color Calibration screen to the TV. Click [Next] and then [Cancel]. This resets any active colour LUTs and loads the ICC profiles to their respective displays as specified in the Windows Color Management page. Sometimes Windows will apply an ICC profile to the TV even though none are listed for the display. Skipping this step can result in strange readings like on the greyscale 100% = 120% Red 100% Green and 72% Blue and lots of head scratching.
Open Firefox and display the YouTube video "TV Static Noise 10 hours" in full-screen on the TV. This will wash the screen of afterglow during the continuous measurements later. Click away any popups.
Connect with ControlCAL to the TV and click [ISF Day] and [Get All]. Full instructions for ControlCAL come with ControlCAL as emails. The TV will show the name of the slider and its value changing when you change it in ControlCAL. Click [OSD Off] after confirming adjusting sliders is working ok. Connect the i1Display Pro placing it centrally on the TV. No special drivers are needed for the i1Display Pro as it just shows up in Device Manager as a USB Human Interface Device. Close the curtains and turn off any bright lights.
HCFR set up
Optionally delete the colorHCFR.ini - on start a new file is created with defaults.
Start HCFR and click [Advanced] > [Preferences] > [References] > [HDTV - REC 709 (75% 75%)], [Display Gamma], [Reference Gamma] = 2.2 [OK].
Click [New] > [Automatic generator] > [Next] > [X-Rite i1 DisplayPro] > [Next] > [Display Type Plasma (EDR for Plasma created with primaries R, G, B and White)].
Click [Calibrate] and move a small notepad window under the i1Display Pro and click [OK].
Enter the following in the Sensor Matrix and click [OK] - Correction matrix to map plasma EDR based correction to JETI 1211 by Zoyd
1.085195 0.009410 -0.003509
0.003101 1.086654 -0.000754
-0.008047 0.014608 1.063265
Click XYZ Measurement = [ON] on the main Measures screen to apply the correction matrix.
Click [Measures] > [Generator] > Set the VT50 as the target screen > Image area = 10% > APL = 0% > Image background = NO > Gray Scale = 0-255 > disable video LUT = YES [OK].
Press Alt + 9 to display the Belle Nuit test image. It should appear on the TV overriding the TV Static Noise video. This should show 12 dimmer than 16 and 255 brighter than 235. This confirms the modes on the video card is 0-255 Full and the TV is not clipping it and it confirms that the setup and settings are suited for calibration. Move the mouse to the image and click and press escape. Note that this is not the only combination that can be used for calibration. See https://www.avsforum.com/forum/139-di...l#post36413890
Press Alt + 1 to display the alignment test image and get the i1Display Pro lined up dead center on the screen.
10 Point white balance calibration
Click [Go] to measure the gray scale and wait for the measurements to complete. The first measurement will be black with a 0:0:0 triplet displayed on the TV and the last will be 255:255:255. Select the 100 column in the Measures Grey scale table and click [Continuous Measurement]. Now adjust the Red and Blue for 100 in the W/B 10PT page in ControlCAL. The goal is to get the bars in HCFR all the same level without touching green. Repeat this for 90 to 0 and click [Go] to measure the gray scale again to see the results. The white balance is now 10 point calibrated.
10 Point gamma calibration
Select the 90 column and click [Continuous Measurement]. Adjust the 90 in the GAMMA 10PT page in ControlCAL. The goal is to get the Y close to the Y target in the table on the Measures page. The Y targets are automatically calculated for 90-10 using the gamma setting when the 100 is measured. Repeat this for 80 to 0 and click [GO] to measure the gray scale again to see the results. The gamma is now 10 point calibrated.
Repeat the white balance 10 point calibration and gamma 10 point calibration again if the results are not satisfactory as the may affect act other. Be careful as measuring the 100 will recalculate the gamma Y targets for 90-10.
Primaries and secondaries calibration
Click [Advanced] > [Preferences] > [References] > [General] > [Use HSV Level Bars] ON > [OK].
Change the View dropdown to Primaries and Secondaries. Click [GO] to measure primary and secondary colours. Select the red column in the table and click [Continuous Measurement]. Adjust the hue then the luminance, saving the saturation for last for Red on the CMS page in ControlCAL. Switch to the CIE Diagram to adjust the hue, then switch back to the measures table and adjust the luminance. As the delta luminance approaches 0%, the Delta E will rapidly come down. Switch back to the CIE diagram and adjust the saturation. Repeat this for the remaining primaries green and blue then do the secondaries yellow, cyan and magenta.
The primaries and secondaries are now calibrated. If the CIE chart is full of continuous measurement points then switch to the Free Measures and delete the many free measures you created while in Continuous Measurement then switch back to the chart.
Repeat the 3 calibrations above as they affect each other. If the Gamma is too coarse (above or below but never spot on despite best efforts adjusting the gamma sliders) for 50 and above then get it slightly above the target and reduce all three RGB sliders by one notch and measure again.
Evaluating the calibration
Click [Advanced] > [Preferences] > [References] > HDTV - REC 709 [OK].
Click [Advanced] > [Preferences] > [References] > [General] > Use HSV Level Bars = OFF > [OK].
Click [Advanced] > [Preferences] > [References] > Colour Checker and choose one > Use measured gamma = ON.
This will use your Average Gamma instead of a fixed 2.22. Pantone skin tones or CalMAN SG (95 colours) are the most useful. Change the View dropdown to Colour Checker and click [GO].
Change the View dropdown to Free Measures and delete the free measures created while in Continuous measurement.
Add some comments like date and dE AVG of the color checkers to the measurements and save them. Also click [Save] in ControlCAL to save the IFCC memory and [File] > [Save settings] to save the TV settings to a file.
HDTV - REC 709 (75% 75%) is a special mode for getting the best calibration for your primaries and secondaries. It uses 75% saturation and 75% luminance. Very little of what is displayed on the screen is 100% saturated 100% luminance - 75 75 is a good target and just because the outside of the CIE triangle is spot on does not mean that the inside is. Compare with the Colour Checker to see the improvement.
HDTV - REC 709 (75% 75%) and HDTV(OPT-Plasma) have no effect on greyscale measurements. But they do have an effect on the Colour Checker. Remember to switch back to HDTV - REC 709 before running the color checker or anything other than grey scale.
HDTV(OPT-Plasma) has control points optimised for plasma and can be used like the 75% 75%.
If measurements are jumpy then clicking the PLAY button in the sensor box will toggle averaging. This can also help when doing continuous measurements of low levels.
This guide is for the Euro VT50 which has a limited light output - moving the contrast above 36 will not increase light output. Because of this fact the two point calibration was skipped in this short guide. Also doing the low part of a two point calibration will cause reds to appear in the blacks.
The internal media player of the VT50 likes to play 0-15 and 236-255 instead of clipping them as it should do. This makes the player unsuitable for displaying test videos. I don't know why it does this but maybe it looks at the content for whiter than whites and blacker than blacks and plays accordingly. The Pioneer black hole demo video is displayed perfectly.
