This paper provides information about the high-DPI (dot-per-inch) feature for the Windows® family of operating systems. This feature helps compensate for the small text size that results from high-resolution displays.

This paper is for display vendors and original equipment manufacturers (OEMs) of ultramobile PCs who must determine the best default screen resolution for their hardware. It explains the concepts that are involved in effective screen resolution, provides guidance for OEMs to determine the appropriate effective screen resolution, and includes a case study that shows the potential trade-offs that vendors might encounter.

This information applies to the Windows 7 operating system.

Included in this paper:

• About DPI and Screen Resolution

• Guidelines for DPI and Screen Resolution

• Configuring High DPI in Windows 7

• Analysis of DPI Settings for Small PC Configurations

• Recommendations and Guidelines
