I bought this monitor and i'm very pleased with it.
a) It was cheap at £140
b) The screen is bright and colours are rich
c) No humming noises as you've experienced
d) I'm running a HDMI cable from the PS3 in the lounge to the monitor in my room - now when the other half wants to watch TV, I can play on the PS3 using my Hanns G - and it works a treat.
