Current Best Known Guide

Follow these steps to enable Dolby Vision on your PC:

Prerequisites

1. Download and install Dolby Vision Extensions and HEVC Video Extensions.

Steps

1. Download Custom Resolution Utility (CRU).
2. Open CRU.
3. Select your display from the dropdown menu.
4. Export the current EDID to a file (e.g., dolbyvisionmonitor.bin).
5. Download AW EDID Editor.
6. Open AW EDID Editor.
7. Open the exported EDID file (dolbyvisionmonitor.bin).
8. Navigate to the Vendor-Specific Video section.
9. Edit the Payload (HEX String).
   1. Below are some known, pre-computed (original -> updated) values:
      • 480376825e6d95 -> 480377825e6d95 (LG C1)
      • 480a7e86607694 -> 480a7f86607694 (LG C2)
      • 4d4e4a725a7776 -> 4d4e4b725a7776 (TCL C825)

      • 4403609248458f -> 4403619248458f (unknown model of Sony Bravia)
   2. If your hex string is not listed above, then compute it via:

      python.exe enable_dolby_vision_hdmi.py __HEX_STRING__

   3. (If you want to dive deeper into the hex string config, consult dolby_vsvdb_calc.xlsm from here).
10. Save the edited EDID as a new file (e.g., fixeddolbyvisionmonitor.bin).
11. Open CRU again.
12. Import the edited EDID file (fixeddolbyvisionmonitor.bin).
13. Run Restart64.exe or Restart.exe found in the CRU folder to apply the changes.
