Windows 7 expanded on this giving Windows the ability to query the actually pixel density from the monitor. If an app doesn’t indicate it supports High-DPI then it is treated as 96-DPI. Originally Windows monitors assumed monitors were 96 DPI (even though they were usually 72 PPI in reality.) Windows XP added GDI+ allowing resolution-independent text scaling, and Windows Vista added support for High-DPI displays, so more physical pixels could be used to display sharper text and more detailed images. ![]() As the screen gets larger, the DPI gets lower, unless you also increase the resolution.ĭPI = (sqrt(sqr(width)+sqr(height))/diagonal 27” or 68.58 cm), but we can use these numbers to calculate the DPI (see More on DPI and PPI below) with the good ol’ Pythagorean theorem. Often times when we talk about monitors we discuss resolution (e.g.1920×1080) and diagonal dimensions (e.g.
