Ryzen 5 2400g
Gigabyte X370 K5
G.skill ripjaws 3200 16Gb (dual channel)
Monitor: Dell SE2717H
Only in this monitor (previous monitor was ok) i haven't display on BIOS.
I have contact with AMD and DELL but no one give me a solution.
The answer from DELL was : " Dell is not going to allocate the money to create a firmware to address an issue with AMD's onboard GPU not allowing the BIOS to be seen. We do not use their onboard GPU. We use Intel's onboard GPU. All you can do is keep checking their site for newer onboard RX Vega 11 drivers and test them. If you need to see the BIOS for some testing purpose, simply connect another monitor."
But when i contact back with amd they say i have to try it in an other pc for warranty, i say to them there is and other people the same problem you need to do something with drivers.
If anyone can help me solve this problem will be nice, i have try the solutions with drivers with open close freesync and change the hz of my monitor nothing of these don't solve the problem.
