The setting no longer sticks in NVIDIA Control Panel when I switch between the "monitors". I tried to reset and re-import but it didn't help.

Not sure what could have happened to make this stop working. The import appears to work as EXP0901- EP-HDMI-RX (transmitter/receiver) has the same listed resolutions as the MEID08E - AE3000 (the projector).

If you imported the projector's EDID into the receiver's configuration and the extension blocks are enabled, then I don't see why it wouldn't work.

It's worth a try. Make sure you install the file with the projector disconnected so that it overrides the receiver's EDID. You can uninstall the file in the device manager by right-clicking on the monitor and choosing "Uninstall" from the menu.

1.There is a check-mark in the extension block. After I imported the Projector EDID using CRU, the transmitter listed the projector's resolution. Thus, everything seemed OK. However, the NVIDIA control panel setting didn't stick when turning on/off the projector (when projector is off it shows the transmitter EP-HDMI-RX; when it is on it shows the projector AE3000).

Note that the name change is desirable because I set AE3000 as the default device for the Sound (in Windows Sound Panel). When the projector is off the AE3000 is removed and the Sound automatically reverts back to the PC Speakers.

2. I next tried to import the INF file into the registry and the name of the EP-HDMI-RX then changed to AE3000 as expected. In this case, the NVIDIA control panel setting did stick when turning on/off the projector as I wanted! However, although this solution solved the NVIDA issue, the Sound no longer reverts back to the PC speakers because the AE3000 device is never removed.

Thus, I would need to use CRU rather than the registry to import the EDID. I just don't understand why it doesn't work anymore (it used to work). Can it be that my current NVIDA driver looks at the name of the attached device and the setting is therefore lost when the name changes? How can I troubleshoot this?
