Not exactly the same model, but we bought a B2712 HDS at work because we needed a big-ish screen for a trade show.
I wasn't impressed with it at all. We've got six Dell 2408WFPs and a Dell U2410 in the office and the quality of those is far better than the Iiyama, but you get what you pay for.
I'd rather have the 24" with the better quality than the 27" that looks a bit ropey, and as far as I know, the max resolutions are the same.
It could be quite different with the B2776 though...
