I recently bought a RX 580 to replace a working r9 280x and the new card does not have any signal even at bios. I have a MSI z97 Gaming 5 motherboard with the newest bios they have and also am using UEFI. The card lights up and it looks like it is booting into windows going my the debug LCD on the motherboard. This is my second 580 card that I have tried and same result. Any suggestions would be great. Thanks.
