ST2220T Audio Problem.
I bought a new headphone. When I plugged it into my ST2220T Multi-Touch Monitor audio plug, I found the sound extremely small. I first thought that it was the headphone's problem. But then, when I plugged it into the computer's plug, the sound volume went loud as what I expected. I then reset the monitor to the factory defaults, but the problem still occurs.
What can I set now? Or this is a hardware problem which claiming for the warranty is the only solution?
Thanks and may God bless.
