High DPI Support in Windows 8.1, 10 Explained [Video]

This video explains the meaning and role of high DPI support in Windows 8.1
We heard for the first time that Windows 8.1 would bring DPI scaling enhancements back in July. Now that Windows 8.1 is finally official, you are probably wondering what exactly it means and what it implies. This video from below pretty much sums it all up, featuring Larry Larsen, Andrew Richards, Chad Beeder from the Channel 9 Defrag Tools online series.

The positive effects of the high DPI support in Windows 8.1 for Internet Explorer 11 are explained by Microsoft:

Internet Explorer 11 brings enhanced scaling for high DPI screens and small slates, ensuring the consistency of your website’s text, touch targets, and layout across Windows 8.1 devices. Specifically, IE11 introduces the following high DPI improvements.

Also, it improves the multiple monitor support

Because Windows 8 uses a single DPI setting, if you’re using multiple monitors with different DPIs, you get a sub-optimal scale factor on at least one of your monitors. IE11 adds per-monitor scaling support, so your web content scales to the correct level automatically as you drag the window between monitors. This is particularly useful when projecting from high DPI devices, as projectors are typically low DPI displays.
