Can you grab a screenshot of your GPU’s Device and SubDevice IDs? you can find those at the bottom of the Device Information menu under SignalRGB settings. Example:
As far as I can tell that GPU is already prepped to be added to SignalRGB v2.2.33, there’s beta builds you can try (which you can get in Plugin test discord server after grabbing the “General Release Testing” role in the #roles channel there). Please be mindful of the changelogs before installing those.
Yeah it’s possible this card was already in 2.2.29, but devs changed how SignalRGB handles some devices in v2.2.31 and they might have forgotten to put it back in. I checked 2.2.31 and 2.2.32 and your IDs aren’t there, but they are in 2.2.33.
