Hi people, i have a weird problem, i have a 8card rig (rx 580 8gb saphire pulse and 1 saphire nitro with a h110 pro btc+ asrock) when i conect the hdmi cable to one of the rx cards no matter what i do, if a switch the risers, conect to a different gpu or anything else, if i put 8 card the system boots, the hiveos starts but it wont start mining it stay in a dark screen with this symbol on top left (_), but when i conect only 7 gpus starts good and mine good, but if i conect the hdmi cable to the motherboard it recognize the 8 gpu and i can mine very good but i have problem with´applying the fans and voltage settings, why do you thing this happen?

Sorry my bad english
