1. Get Phoenix EDID Designer, (
https://www.tucows.com/preview/329441), unzip and run the exe (no install reqd)
2. Click Tools->Extract registry EDID, then double click the line for your TV/monitor in the popup
3. Click Tools->Byte viewer, and note down the values in row 00, columns 08-0B (4 bytes)
4. Start the installation of the latest Nvidia drivers and cancel out once the files are extracted
6. Open the file "nv_disp.inf" in a text editor. By default for the current drivers this is in C:\NVIDIA\...\169.21
7. Scroll down to the section [nv_SoftwareDeviceSettings], add the following line there, replacing the "XX" values below with the 4 values noted in step 3:
HKR,, OverrideEdidFlags0, %REG_BINARY%, XX,XX,XX,XX,00,00,FF,FF,04,00,00,00,7E,01,00
(In my case the TV code was SYN 0043, the four values being: 4F,2E,43,00 )
4. Uninstall your current drivers and reboot
5. Install the modified drivers by running the previously extracted setup.exe. By default for the current drivers, this is in C:\NVIDIA\...\169.21. You'll get a warning about the driver not being signed because of the modified inf. Just press OK.
Reboot, and you should have GLORIOUS AUDIO!!!
