![]() ![]() We generally use 2K with a monitor having roughly 2,000 horizontal pixels, 3K with 3,000 pixels, 5K with 5,000 pixels and so on. There are so many variations of horizontal and vertical displays, and the name and standard overlaps with minor pixel differences. What is my screen resolution A simple online tool that shows you basic display information about your device. The following display standards have evolved into the current resolutions. The ratio between the horizontal and vertical has changed from 4:3 to 16:9, and the 16:9 aspect ratio is the new normal used on most monitors today. Today, the most commonly used display resolution is 1920 x 1080. In the late 90s and early 2000s, the 1024 x 768 was the most common resolution used. Raise NotImplementedError("Handling %s is not implemented.The display industry has advanced dramatically over the years, and monitors with 2K, 4K, and 8K resolutions are not uncommon these days.

I am using a get_screen_resolution method in one of my projects like the one below, which is basically an import chain. I'll use the 158 to make sure my Matplotlib plots are the right size with: from pylab import rcParams My display scaling sets my current DPI to 158. I am running Windows 8.1 with a 220 DPI capable monitor. Which returned: Width: 1555 px, Height: 875 px Print('Width: %f dpi, Height: %f dpi' % (width_dpi, height_dpi)) Print('Width: %f in, Height: %f in' % (width_in, height_in)) Print('Width: %i mm, Height: %i mm' % (width_mm, height_mm)) Print('Width: %i px, Height: %i px' % (width_px, height_px)) Note that I call SetProcessDPIAware() to allow the program to see the real resolution. I'm able to get the correct full screen resolution, and current DPI with the below code. (reported_px*current_dpi)/(96 dpi) = physical_px The formula for reported system effective resolution is: Per this Windows site: Adjusting Scale for Higher DPI Screens. Reported python resolution: 1555 x 875 (158 DPI) High DPI Desktop Application Development on Windowsīasically, rather than displaying content the full monitor resolution, which would make fonts tiny, the content is scaled up until the fonts are big enough. Types of DPI aware applications are listed here: It appears that python is by default a 'system dpi aware' application. I found out that this is because windows is reporting a scaled resolution. ![]() To get the correct full resolution of a high DPI monitor on Windows 8.1, one must call SetProcessDPIAware and use the following code: import ctypes Other people are having this same problem for ctypes: getsystemmetrics returns wrong screen size On Windows 8.1 I am not getting the correct resolution from either ctypes or tk. ![]()
