Measuring display sharpness

Overview

Pen displays have some anti-glare treatment that introduces a small amount of blur. It can vary widely between pen displays. I've created a simple test image to so I can consistently evaluate the blur.

Test image

It's a small PNG file with black and white pixels.

There are 8 samples.

Process

  • Open the image in Krita

  • Set the zoom to 100% so that every pixel in the image corresponds to exactly 1 pixel on the display.
