Just got my brand new Samsung 226BW LCD monitor today and was gutted to see a horizontal flicker when plugged into my Toshiba A100-110 lappie (clearly visible with greys and black backgrounds). Called Samsung support – they suggested trying another PC to see if had a flicker – I did and no flicker! Still happening on my Tosh though even after updating graphics drivers etc. Now I don’t know whether to just try and exchange the monitor for another one. Anyone have any suggestions? Please?!
