This is why I try to confirm with dealers via phone about anything before recommending anything. 880GMA wasn't there and most people confused it for 880GM.
For a moment I thought its the author that might have confused with the model numbers but someone needs to be in touch with the writer for reconfirming. These guys said that its for 14k:
Dell ST2220T Multitouch Monitor Specs, Review & Price
Whereas other tech PR spin blogs quoted the $ price. Its just not possible. A u2311H itself costs 14k on retail. Looks like the writer did a look up on the internet and found this, must have not checked it.
Its looks to me Price India converted the Dollar value (most like 45 Rupees per dollar) and chipkaoed it. There's no official pricing put out.
Its about time people give the source of the price rather than leaving people in the dark. These are the only screens for that price from dell on retail:
Dell ST2220L 21.5†W Full HD Monitor with LED
Dell SX2210 21.5"wide Flat Panel
Dell UltraSharp U2311H
Most likely the author wanted to mean was ST2220T or the U2311H.
