My (15 month old) Dell monitor developed a problem - intermittent line of dead blue pixels resulting in a yellow vertical line across the screen. http://i46.tinypic.com/vigwlk.jpg So I call Dell about 12am yesterday. No problems, we'll send a replacement, they call back to say it won't be later than Monday pm. It arrived this morning (Sat 10am) - less than 24 hours. Now that part impressed me - truly fantastic service. Replacement monitor is a "refurb", but looks fine/unused clean condition, recent production date stamp. Hmmmm... So I plug it in and at first it's okay, and after 1/2 hour, the darned thing is consistently flickering badly (whole screen quickly dimming) about every 4 seconds or so. They've replaced my dud monitor with one that's even dudder. (yeah - I've checked by swapping between VGA/DVI connections and on 2 PCs for both monitor problems - but I'm not paid to be Dell's QC checker). I'm starting to get a bad feeling about how this is going to turn out.
