Hi everyone I need a little help here, I am very affected to refresh rate flicker on monitors. I was wondering if refresh rates on LCD monitors can have a flicker like they do on CRT's. I only ask because I just bought the Dell 24 2407 and I seem to notice a flicker and a headache associated with it when I sit and look at it for 15+ minutes. I never noticed anything like this on my old 17" LCD Apple Studio Display, AM I crazy or is this a problem. Also will the 23" Cinema suit my needs better? Thanks.
