Windows Phone 7 will support resolution of 320 × 480
Developer XNA Game Studio Sean Hargreaves (Shawn Hargreaves) wrote in his blog that future phones on Windows Phone 7 will support the resolution at only 480 × 800, but the lower 320 × 480, which will install this OS on a cheap device. Hargreaves believes that with the phone's screen will be easier to deal with three-dimensional graphics, even without super-fast processor.
As previously reported, Microsoft will make certain demands on producers smartphones on Windows Phone 7. At one time it was believed that the resolution 480 × 800 would be minimally acceptable, but if the statement Hargreaves is true, it means that at least some of the phones on the new OS will be relatively inexpensive.
