Hey guys, There have been a number of discussions on the Dell and Toshiba forums regarding issues with the Encore and Venue 8 Pro not enabling users to DUPLICATE (Mirror) their screens via Miracast and HDMI. Instead it appears that the machines are forced to EXTEND. Which is completly pointless on a tablet as you have no way to control the 2nd screen. Dell Discussion Here: http://forum.tabletpcreview.com/dell/59427-venue-8-pro-miracast.html Possible Encore fix here: http://forum.tabletpcreview.com/toshiba/59957-encore-owner-s-lounge.html However I have not been able to get it to work (This was after my Encore was fully patched with the latest Windows updates). It may work on a NON Patched Encore) Microsoft seem to know about the problem You cannot duplicate the display to the second monitor on a Portrait-First device that is running Windows 8.1 From my own troubleshooting the Encore appears to supporting screen Mirroring (Duplication) via HDMI and Miracast when it comes out of the box (Stuck at 800x600 resolution). The moment that Windows 8.1 downloads updates onto the Encore the screen mirroring (Duplication) stops working and you are only able to extend the display. From what I can gather it maybe a mix of issues with Intel and Microsoft: - Intel not having updated software to support full resolution mirroring/duplication via HDMI and Miracast - Microsoft not having updated software to enable mirroring/duplication on 8" devices. What fixes/troubleshooting have people performed?
