For users who use an HDR/BT2020 enabled Sony projector and are not satisfied with the original HDR10 gamma curve, there is a new possibility.
A small team from Germany has decided to achieve an improvement here.
Also in this forum one has become aware of our efforts.
In a second step, we were able to offer ready-made HDR gamma curves, which are loaded into the projector with the Sony ImageDirector:
Here is also a guide to save your own gamma curves with the ImageDirector. We also need it for the next step.
But now the User Mule from the German HIFI-Forum, with the support of Dutyfree and Omardris, has adapted the familiar ARVE tool so that it can be used by Sony projectors.
creating your own Gamma curves for Sony projectors which can directly be uploaded to the projector with Sony Image Director software (tested with V3.1).
This Tool is a modified version of ARVEHJ's project and can be found under:
The direct download link to the ZIP archive of the current version 1.2.1 is:
The following changes had been made in comparison to V0.0.2 developed by ARVEHJ:
•Creates 1024 (10Bit) steps Gamma curves for Sony-Projectors instead of only 256 (8Bit) curves for JVC projectors
•Creates Sony Image Director compatible files ( .ldt) which can directly be uploaded to a compatible Sony projector via Image Director
•Disable JVC specific menu entries
•Bugfix to avoid corruption of config files
•naming convention of config files has been changed to .sconf, because existing .conf files for JVC projectors are NOT compatible with this tool
Python 3.6 or later installed
Sony Projector with Sony Image Director (latest V3.1 tested)
Otherwise, the operation of the original tool from Arve has not changed.
We hope that the ARVE tool specialists in this forum will assist the Sony users in using the tool.
Our thanks in any case to Arve of this publication has expressly agreed and of course to all users who have already diligently tested the gamma curves and hopefully will provide much more input with the now available options for tuning the image quality of the Sony projectors!
