Does signal rgb support radeon gpus or is it only nvidia?
Currently only nvidia as “self-controlled” devices.
Some radeon GPU AIBs (e.g. sapphire) have a 5v 3pin argb input header to connect them to a motherboard or lighting controller port so that other device can handle the RGB lighting, In that case SignalRGB will be able to control it as a component (like your ez-diy strips)
