So as title says, my Acer H223HQ has started making a high pitch sound when it's on standby, starts a few minutes after turning the computer off almost inaudible and raises up to a certain point not too loud but decidedly annoying as background noise. He's connected by HDMI and i don't use the in-built speaker (volume turned to zero), haven't tried any other cables because i don't have any spare atm. Turning it off doesn't help and the noise only disappears when i unplug the power cable from the wall. Would you think this is age starting to show (he's 6yo-7yo) or is there another way around this ?
