Microsoft is going to support 1080p, aka Full HD resolution and it’s going to bring this to Windows Phone 8 via an update in the Holiday season, called GDR3. Currently, we’re all on GDR1. GDR2, which is going to come some time in May-June, is going to bring a couple of new features and fixes/improvements, but the GDR3 update already seems more important.
A GDR is a General Distribution Release. Apart from supporting higher resolution displays, the GDR3 update will also bring support for the newer Qualcomm processors, optimizing the OS for quad-cores. That’s as much we know about it as of now. This is different from the ‘Blue’ update, which is supposedly going to come in early 2014.
