#23439 (Bug) graphics drivers or hardware do not support loadable gamma ramps or calibration
Computer – Windows Desktop with NVIDIA GeForce 1050 graphics card. Windows 10 64bit
I have been running with an old version of DisplayCAL which has been working fine. I updated the version to 184.108.40.206 the other day and updated the ArgyllCMS to version V2.1.2 as well. I now get a message “Your graphics drivers or hardware do not support loadable gamma ramps or calibration. You may need to update your device drivers. ” and cannot calibrate anymore.
I have updated the NVIDIA driver to the latest version (220.127.116.1166) and with help from the NVIDIA team did a clean install and checked the spec etc. after this did not solve the problem. They have confirmed that there should be no problem with loading a Gamma Table or Calibrating on the 1050.
There is a post on the forum on this subject which recommends various restarts etc, but this has not worked.
I posted a request on the forum for a legacy version of DisplayCAL, so I could roll back the version, but no response as yet. The only version I have been able to get hold of is 18.104.22.168 and when I have uninstalled the update and installed this version using the latest ArgyllCMS everything works again. So I believe there is an issue between my system and the latest update.
I have included a log file from both the update and the working version (22.214.171.124)
