Hi! I have installed Windows 10 Technical preview on a Hyper-V VM (1st Gen.) on a Windows 8.1 Pro with Media Centre host on my laptop (with a widescreen 1366x768 monitor). The guest OS runs fine, but the problem is that I am unable to select a widescreen resolution for the guest. The resolutions available are all 4:3 resolutions and the closest I could get to fullscreen is 1024x768 which displays annoying black bars on the left and right of the guest display on my monitor. How can I get the guest (Windows 10) to recognise my native resolution? Thanks in advance.
