Rx 6750 XT Chroma & RGB Support

[Timmiieehh]

Hi everybody, 

I recently bought my first Asrock item, the RX 6750 XT Phantom GPU. 

I am trying to 'expirement' with the rgb settings. I already have Razer Synapse installed because of other peripheral hardware. I also downloaded the Asrock RGB Polychrome Sync app and followed the tutorial to connect both apps. Unfortunately it wasn't successful. 

In the Polychrome App I cannot see the the Razer Chroma button which, based on the tutorial, is supposed to be there on the main page. I am curious if gpu's are also compatible to connect to Razer Chroma or if this is for motherboards only. 

I also want to know if the ARGB led fan connector on my GPU is there to connect it to other hardware devices or can I connect it to my motherboard? This is a Gigabyte B550 Aorus Elite v2 which has arg led fan input connectors placed on the board. My goal is to use as less RGB apps as possible, it seems that is an ongoing issue for everybody, unfortunately. I have asked the same questions on the assrock forum but no response. 

Thanks in advance for your response.
