hi so after getting in touch with sapphire they told me that if u have lower res screens then the gpu will make it the "main".
"How about output ports? Are they all straight connection or they are going through adapters? If the monitors are different make and models and specification, if 3 monitors have different max resolution, the multiple monitor setup will take the monitor with the least resolution and make that one the standard, so I think that is the issue you are having."
also i didnt reset my pc after unpluging the cables so i couldnt see any difference.
