LG C3 with EDID modification does not keep the "Enable HDR"

[bensonjohnson]

First off I would like to say long time fan of BetterDisplay. I recently updated macos to 26 tahoe as well as to the latest version of BetterDisplay. I was prompted to repurchase a pro license again as it had been enough updates? I was a little thrown off by this, but honestly the value is there so no real complaints. Let me get to the "bug":
I am using an M4 max Macbook Pro with a dell HD22Q and an LG C3. I did the EDID modification to spoof the HDMI port to being Displayport over thunderbolt to get to 4k 120hz / HDR. This worked for probably 2 years with no issue with a couple different macbooks. For some reason now with either macos or the newer release of better display it will not remember the HDR setting. I can enable it no problem, and it retains the 4k 120hz setting. If I reboot though it has HDR off and I have to turn it on pretty much every time I plug the macbook back into the dock. Its a minor annoyance I will admit, and I would probably look past it if I didn't have to pay for a pro license 2x.

Let me know if you need anymore info.

Hi there - I don't think it's an app issue but probably a change in how macOS remembers display layouts. Anyway, you can use the app's Configuration Protection feature (see the similarly named menu item under the display) to "protect" the HDR setting if it does not get restored with the layout.

Let me know if this does not work.

The protection feature does indeed fix my issues. Appreciate the quick response.
