randomly wrong screen resolution

[corbax]

Hello guys. 

I am running 2 monitors for a while now. But recently when I start my PC I get three solutions: resolution of the second monitor is 1280x1024 (most common but can be any resolution), 1920x1080 (which is normal) or the second monitor won't even turn on but it will display msg reading "OUT OF SIGNAL 75kHz/60Hz". First I was running xfx Radeon r9 270x but as it was on end of her life I taught it was because it is dying but then I changed my GPU to sapphire r7 260x and the problem is still here. 

 

PC spec:

CPU: FX-8320

RAM: 8 GB

GPU: Sapphire r7 260x

PSU: Raider 650 W

Some basic MSI UltraDurable motherboard

Hard Drive: WD blue 1TB 

 

Main monitor: LG 25UM58-P (connected via HDMI)

Second monitor: LG 23MP65 (connected via vga cable + dvi to vga adapter)

 

Running Win 10 64 bit

Maybe your VGA cable is degrading? Have you tried switching it out?

I was thinking about it but wanted to hear some other opinions. should then be better to just buy DVI cable instead VGA

your your resolution it doesn't really matter but yea, I'd still go with DVI/HDMI or even DP
