Bios update problem

[francesco991123]

Hi, I updated the motherboard drivers and a problem arose, with the dp the monitor goes on the 1024x768 resolution, with the hdmi normally goes to 1920x1080, I also tried to change the input of the dp on the video card since it has 3 but if I change the monitor it turns black and does not detect any signal, what should I do? The motherboard is the asrock ab350 gaming k4, gtx 1070 g1 video gaming board and the monitor is an aoc g2770pf, the motherboard with version 4.60 works perfectly instead with versions 4.70-4.80 and 4.90 has this resolution problem
Returning the base frequency processor the problem disappears, but first with the 4.60 oc it was fine
Why?

When posting a thread of troubleshooting Nature, it's customary to include your full system's specs. List them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

If latter revisions of BIOS causes the problem, then stick with the latest most stable revision. Out of curiosity, did you try uninstalling and reinstalling your GPU drivers after you updated your BIOS?
