Audio Output from Monitor Buzzing Noise Problem!

[kennyreid95]

Hey guys I need help with my Acer H257HU Monitor audio output making buzzing noise to external speakers. Whenever I play games like Borderlands 2 or an older game Burnout Paradise I hear a buzzing noise coming from my external computer speakers plugged into audio output from monitor. I made sure the green audio cable is plugged all the way in monitor's audio output and it still makes buzzing noise. Listen to it for yourself. It is really annoying noise. I am 100% sure there is nothing wrong with my Acer H257HU Monitor.

Here is the recorded audio clip of the buzzing noise I hear from monitor audio output to external computer speakers.

Do the speakers make a buzzing noise when plugged into the audio jack on the back of the computer as well?

If not, it is an interference issue of some sort, and even though you are sure it's not your monitor, it could be your monitor.

Ok I really feel stupid now. All along the problem was DVI. DVI was causing buzzing noise all along. DVI is very obsolete why did I not think of using newer better HDMI or display port? Because I thought I could only use external speakers through DVI and I was wrong. I can use external speakers with HDMI by plugging in external speakers in audio output of monitor with headphones icon and I don't hear buzzing noise anymore using HDMI

Has nothing do do with HDMI. The buzzing you heard was unshielded noise coming from your pc because that is where the analog signal was generated from. Now it's being generated by the monitor which is better shielded and isn't putting out much rf too I imagin.
