Bought a gigabyte gtx 750 ti and it didn't really work.. hoping to get the rx 460, just worried it might not be compatible with legacy bios and same thing happens.
What Motherboard are you using?
I'm using IPISB-CH2 (chicago). To be more specific I bought the XFX Radeon RX 460 2gb single fan. I read that specific brand was compatible, it's just when I installed it, my monitor isn't getting a signal.
All you can do is try updating to the latest version of the Motherboard bios. If it does not work then it is not compatible and may require a further bios update from HP.
