Hello, i have a problem with external monitor. I used my main monitor (LG 29WL500) with rx 6700 xt through hdmi, because this monitor have only hdmi output and everything work fine. One week ago i bought second monitor (AOC 27b2h/eu), who have just hdmi output too. On mine gpu i have 1 hdmi and 3 x DP. So i bought dp to hdmi cable and that's where I get to the problem. On second monitor show bios, but when enter in windows just main monitor work and on external it says no signal. Windows detect second monitor and i can change resolution, fresh rate and everything but still image doesn't get. Sometimes i random get image on few seconds and then back again black screen. Does anyone had this problem and know how to fix it?
I've Tried:
Bought 3 different cables and adapters, always is the same problem
Connect both monitors through dp to hdmi, then i had black screen on both monitors (but bios logo show)
Tried DDU in safe mode, then install again new driver for gpu and nothing changed
Changed PCIE and PCIEX16 to gen 3.0
Updated AMD Chipsets
Updated BIOS
Tried cables and adapters on other pc, everything works fine so its not cause of faulty cables
Tried all 3 display ports on gpu (hdmi work without any problem)
When booting pc and both monitors are connected, pc in first 10 seconds are so lagging (on second monitor light indicator is white, but getting image just sometime)
