About

I am a software developer who is enthusiastic about many subjects, including algorithms, computer graphics, analog/digital electronics, science, and engineering.

I use this space to organize my thoughts on various subjects, which may be incomplete or inaccurate, but may still have value for those willing to excercise a bit of skepticism.

Display Transfer Curve Tester

2018 Jul 30, Mon

A small application to determine a display’s approximate transfer curve using a series of test patterns.

Scroll up or down to match brightness, then click to move onto the next pattern.

Results will be displayed in a graph with ideal sRGB and Rec. 709/2020 curves for reference.

Instructions

Measure a monitor's approximate response curve using a series of test patterns.

The test patterns must be viewed at native resolution with any "sharpness" adjustments disabled. Results have not been validated against a ground-truth (i.e. a properly calibrated colorimeter).

Scroll up/down to match color, then click to advance to the next pattern, repeat.

Select test patterns
