crookedvulture writes "Giant, high-resolution LCD monitors have been around for years, but they've always been prohibitively expensive. Good displays based on IPS panel technology command upwards of $700 for 27" models and closer to $1200 for 30-inchers. However, Korean vendors have started selling similar screens on eBay for roughly half the price. These off-brand models purportedly use the same panels as pricier alternatives, and in practice, they appear to be nearly as good. There are some caveats, of course. The number of inputs may small, HDCP support isn't guaranteed, and user controls can be limited. Those may be deal-breakers for some, but getting a 27", 2560x1440 IPS display for well under $400 will be a deal-maker for others."
