Truly there is no way to disable DSC?

[Notoriel]

I sometimes would like to disable DSC on my monitor simply to use DLDSR 2.25x in some games, it has a DSC toggle which is always on, always greyed out and it cannot be disabled under any circumstance whatsoever, not even through the service menu. It is simply hard-locked to On no matter what. I could run in 480p 30hz 6-bit and it would still use DSC on both DP and HDMI.

I searched for ways to disable it manually and the result was that it's impossible or literally no one tried to for some reason, is there truly no way to disable it using a windows program? CRU doesn't seem to have that ability, even though it would make sense? Is DSC like one of those hardware things that cannot ever be disabled by the user unless the manufacturer very specifically allows for this with it's firmware, and you can't ever do anything about it otherwise?

It will absolutely be dependent on the monitor's firmware. It's an encoding/transmission format. It is not something that is automatically enabled beyond the native connection bandwidth without the monitor's firmware dictating that behavior.
CRU is entirely unrelated to that process.

I would also note that if you want any specific help with your display, you're going to need to share the specific model you're talking about. Since it has a DSC option listed, even if it's currently greyed out, it's very likely that there is an alternate configuration that allows you to disable DSC.

Ah yes, sorry about that, I forgot to mention the model.

The model is the TCL 27R83U. Under the Menu - Settings options it has several options, with DSC being one of them. It is the european version of the FFalcon U8 miniLED sold in China.

Are you sure that CRU doesn't disable it? Have you messed around with the Extension Block?
