    I just posted an article specifically for the Surface 3:
    http://blogs.msdn.com/b/danchar/arc...tel-atom-x7-cherrytrail-multi-mon-tweaks.aspx

    This addresses the same concerns folks had for the Surface Pro 3 and offers a quick regkey workaround to set lower resolution 3:2 aspect ratio modes to avoid black bars (letterboxing). Hopefully the next Intel driver update will include these resolutions by default.


    Here are the resolutions I tested and added to the regkey hack:
    • 1920x1280 213.7dpi 100% scaling native resolution at 10.8 inches diagonal
    • 1800x1200 200dpi 106% scaling
    • 1728x1152 192dpi 111% scaling
    • 1530x1020 170dpi 125% scaling (Intel driver may round to 1528x1020 which isn't exactly 3:2 ratio)
    • 1440x960 160dpi 133% scaling
    • 1350x900 150dpi 142% scaling (Intel driver may round to 1352x900 which isn't exactly 3:2 ratio)
    • 1278x852 142dpi 150% scaling (Intel driver may round to 1280x852 which isn't exactly 3:2 ratio)
    • 1200x800 134dpi 160% scaling
    • 1152x768 128dpi 167% scaling
    • 1080x720 120dpi 178% scaling (can't run modern apps on Surface screen)
    • 1020x680 114dpi 188% scaling (can't run modern apps on Surface screen, Intel driver may round to 1024x680 which isn't exactly 3:2 ratio)
    • 960x640 107dpi 200% scaling (can't run modern apps on Surface screen)


    Cheers,
