I setup a Samsung 225BW monitor yesterday (£195 with Googlecheckout from ebuyer.co.uk) and it buzzes
It's not as bad as the 205BW I returned to PC World but it still annoys me. The 205BW had a psu problem - when the brightness was below 90% it would buzz. The 225BW buzzes at all brightness settings - even over 90% but it's not as loud as the 205BW.
Anyone else having similar problems? You may have to put your ear close to the monitor to notice.
I can notice the buzz for two reasons - I have a quiet computer and sensitive hearing.
(I opted for the Samsung over the LG, Daewoo and Viewsonic 22" monitors Scan are selling as I thought it would be better )
