So I recently bought an used rx 570(after confirming it is in working condition) and tried to connect it to my monitor using dvi cable but I got the message 'cable not connected'. Assuming the cable being dead as it was lying for 7-8years unused,I bought a vga to dvi converter but I still get the same result that is the cable is not connected. Anything else can I try before I send the card for rma?
