Doesn't seem like there's a 'fix'. RX 2XX series cards (other than rebrandaed 77XX series cards like the 280 etc) dropped support for 103, which Dell used for BIOS resolutions. Nothing you can do about it, AFAIK, with that GPU.
What are the rest of your specs? The only info I can find on this error appears to relate to a conflict between DELL system BIOS's specifically, with aftermarket GPUs....
