Hello there, today a built a new system with ryzen 5 2400g apu and gigabyte a320 motherboard, after assembling as I connected it to my Acer monitor ( 2008 model) it says no signal but keyboard led is on and caps lock is working. Then I connected it to my friend's monitor which is an AOC monitor (2018model) it just works fine. Then I checked my monitor with a another system but it works fine. I connected my newly assmbled system with another 2008 model monitor then also it doesn't work. I do not understand why is it happening. I am using the same VGA cable to check with every monitor. Please help me . I am out of my mind.
