is there a rating? for lcd's for their anti-glare properties? its time for a new screen i think so i was wondering if they rate this or are they all the same? what should i look at? resolution,contrast ratio and brightness? resolution looks to be the same with most of them but contrast and brightness seems to vary. probably should go with a name brand like dell,viewsonic,toshiba etc. or are these "other" brands made by the same company just with a differnt name?
