Hi all,i bought 2 Hanns.G HG281D 28 Monitors from overclockers on the 20th of november 2009,both were working fine but last week a problem started with 1 of the monitors,The problem is that i have visible flashing dots running down the screen of the monitor and the whole way across the monitor about 1 inch apart,do i contact hanns-g to replace it or is it up to overclockers to replace it,thanks all
