Tim did a post on cheap 27" IPS 1440p monitors from Monoprice within the opening days of the calendar year. These panels are derivative of the type you would see on Dell Ultrasharp or Apple Cinema Displays. We say derivative because LCD panel manufacturing is very imprecise: completed panels get graded, bin-sorted, and sold to bidders. A panel which does not grade high enough for Dell, Apple, HP, and other professional companies is probably still a perfectly good panel and suitable for other bidders. Monoprice is putting their branding on one of those bidders and selling it for under $400, about a third of the cost of the A+-sorted panels.
And they're gone.
Now, almost three months later, Monoprice has caught up and will start shipping the new batch as early as tomorrow. How long that will last, who knows? If you wish to have a high end monitor on the cheap, you will probably want to run and not walk.
The Monoprice CrystalPro WQHD monitor is available for $390.60. Monoprice advertises the display to be perfect for Eyefinity setups… except that it is limited to one per customer. Oh well, troll well.
