Depending on your graphics driver and your monitor there might or might not be a workaround around that, but consider the following:
1)
The paragraph you are quoting from is titled Minimum resolution and snap
. Minimum.
Now go to the next chapter:
You can run Metro style apps on a screen
...with a resolution of 2560x1600
.
To me that reads as: You need at least 1366x768 to enable all features.
2)
You really do not want to use a LCD screen at anything but its native resolution. If you do you either only use part of the screen (no stretching), resulting in black barso Or you stretch the image, resulting in an image with distortions (and headaches after a few hours of looking at that screen).
Exception: Fractions of native resolutions are fine. A 1080x1024 monitor at 640x480 or 320x240 is usually fine)
