drivers for graphics card

I am looking to replace a defunct display on my cnc lathe.
.I have a compact touchscreen I was hoping to fit and intending to use Gmocappy.
This screen has HDMI input and I have a DVI to HDMI adaptor cable .

I have fitted an AMD Radeon R5 340X in my PCIE slot but Linux is not recognising it or finding a driver . My PC is Intell low profile
AMD website is not easy to navigate for a linux driver for this .

Can anyone explain to me how to go about getting this card recognised in linux Debian , to get me a suitable output to my display

TIA John
