Previously there were reports that Microsoft is working on bringing in 1080p screen resolution support for Windows Phone 8. This is some evidence now, which can be construed as proof for this. The company is reportedly working on a update called GDR3 which will bring support for full HD 1080x1920 resolution.
Justin Angel, who is a former employee of Microsoft and Nokia has managed to find some emulator files for Windows Phone, which happens to support 1080P resolution. The files come in the format of Visual Studio 2013, which was previewed during Microsoft's Build conference, which happened recently.<blockquote class="twitter-tweet blockquote"><p>Good news everybody!

Let's understand what emulator files are - they are basically files that are used by developers for running a virtual Windows Phone on their computers. This helps them to see how the apps would appear and perform. Suppose if the emulators support 1080P, then it will allow developers to test apps in such a resolution.
This also means that smartphone manufacturers will be able to make windows phone based devices with displays that support similar resolutions.
The GDR3 update for Windows Phone 8 is expected to be made available for hardware vendors by the end of this year or early 2014. There is also expectation that the new update might bring support for Qualcomm's new quad-core Snapdragon SoCs that are popularly used in HTC One or one of the Samsung Galaxy S4 variants.
