Doesn't Asus have the 3 year quick exchange warranty for all their monitors? It is amazing they're the only one who does this.
Asus has one of the highest in the monitor industry, yes, 3 years warranty for MOST of their monitors. Viewsonic also is about the same and meets their quality standards and warranty (and viewsonic has an awesome reputation and dead pixel policy on most of theirs). I don't think I would choose any other monitor companies just based on that and my experiences with both brands.
