I am mostly interested improving the Bravia display from the internal image viewer. It is waaaay off now for those jpegs on phones via the roku app or via the Smugmug app.
Oddly the video though clearly off, is at least acceptable. I am probably more critical of still images especially when I know what they should look like. Thank you for thinking about this.
Hi, to be able to make further improvement of your Lenovo and your BRAVIA also, you have to buy a colorimeter, the best choice for value/money/performance is the X-Rite i1Display PRO.
For your Levono or any other notebook/PC Monitor calibration, since you will have i1Display PRO, you can download and use the X-Rite i1Profiler software.
i1Profiler It's direct connecting with your Monitor RGB Balance controls (when this is possible, or asks you to do this manually and guides you what adjustment you need to take to do an initial White Calibration....usually monitors have 1-point of RGB balance controls for that). Later it will autoadjust the Grayscale/Gamma by adjusting the output of the video signal that it goes to the display (VCGT). It will measure some colors also and it will generate an ICC file. To fully take advantage of the ICC correction (Gamut Correction) you need an application that can read ICC correction, software like PhotoShop (from inside PhotoShop preview window you will be able to see Gamut Colors Correction.)
To your windows or other applications that is not supporting ICC, it will correct the VCGT (Video Card Gamma Table), this means RGB Balance (Grayscale) and Gamma, your Gamut is not corrected by VCGT.
For your BRAVIA, usually the internal picture players has disabled some of the display calibration controls, if you see that you have at least 2-Point RGB Balance controls (or 10-Point if you have newer BRAVIA model) then you will be able to do grayscale calibration.
For calibration software to use with your BRAVIA, there 2 free calibration software solutions, you can download:
1) HCFR from here
with support forum topic: HCFR - Open source projector and display calibration software
2) The Free DPS version of LightSpace CMS
can be used also with an i1Display PRO meter, there available to read various guides
on the Light Illusion website.
The specific guide for use with LightSpace DPS is here
But there is a lot of potentially useful/interesting info in the various guides on the website also.
Support forum topic: Free LightSpace DPS - Manual Display Calibration
Since you will calibrate the BRAVIA for PC-Data Levels (because pictures or internal viewer working in PC-Data Levels also, you will need to create some patches for PC-Data Levels also, load them as pictures to the viewer and taking measurement wth HCFR.
For Contrast/Brightness adjustments you can download the Calibration Images from here: http://lightillusion.com/downloads.html
To create some images for 11-Point Grayscale and Colors use a image processing software (like PhotoShop or any freeware) to create some pictures using these RGB Triplets:
For 11-Point Grayscale:
0% Black -> 0.0.0
10% Gray -> 26.26.26
20% Gray -> 51.51.51
30% Gray -> 77.77.77
40% Gray -> 102.102.102
50% Gray -> 128.128.128
60% Gray -> 153.153.153
70% Gray -> 179.179.179
80% Gray -> 204.204.204
90% Gray -> 230.230.230
100% White -> 255.255.255
Once you have calibrated the image viewer, load the same images from the mobine app you are using and check if you have aggrement with results you get from measuring the images from BRAVIA image viewer.
So having i1Profiler for your Levono and HCFR/LightSpace DPS for BRAVIA, you can match the target peak luminance and gamma setting also between both displays.
For BRAVIA calibration for Movie playback using it's USB Media Player or a stand-alone blu-ray/media player you may have, you can use my calibration disk as a pattern source.
To calibrate a Display, initially you will need to start by setting Sharpness/Contrast/Brightness with my disk and then move to measurements with HCFR/LightSpace DPS with you meter. You will start using the Movie Mode (which is the best performing mode from all the other movies that each TV is coming), disable enhancement, and measure the Warm 1/2 with Grayscale patterns to see which has better RGB Balance and it's closer to D65 (The White Point that REC.709 colorspace is using). After that measure the available Gamma Options (0,-1,-2,-3) to see which one is closer to your target gamma (2.4), recheck again contrast/brightness and then move to Grayscale calibraition. If you display has 2-Point and 10/20 Point RGB Balance, then start with 2-Point and use 100% White patch to calibrate using the RGB-Gains (RGB-High) controls and then with 30% with RGB Cuts (RGB-Low) controls, recheck always both and contrast/brightness again, after that move to 10/20-Point RGB balance for further adjustments and use the 11/21-Point Grayscale Chapters. After the end of Grayscale calibration you will move to Color Gamut check to see if there required some adjustments to Color/Tint controls (since Sony don't have controls for Full CMS adjustments....6-Axis CMS).
About using HCFR, there info @ AVSForum thread: HCFR - Open source projector and display calibration software
There is a user tutorial here: The certainly not complete user guide to get to know and calibrate your TV
The settings for HCFR per measurement run if you will use my calibration disk, I have posted them here also: Ted's LightSpace CMS Calibration Disk
For improve your calibration knowledge, here are some useful links generally for calibration:
