I have a firepro W8100 Graphics card which have 4 output ports，each port connect to a monitor. My PC's OS is ubuntu 20.04. I want to splice the 4 monitors to a unified desktop ,But I'm not sure how to set it. If I use Nvidia graphics cards，I know I should use nvidia-settings to set mosaic ，but amd doesn't seem to have similar software. So if I want to implement this function，what should I do ？I know amd graphics card has Eyefinity mode，but I don't know how to use it in ubuntu，Is there an expert who can give you some advice please？Thank u very much！！！
