Solved Surface 3 (Atom) Dpi-scaling / multi-monitor tweaks - regkey hack

[surfdock]

I just posted an article specifically for the Surface 3:

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)
