Re: Measurement Device for Display Lag


imo the only thing i care about is
how much slower is a display than a "perfect display", if both are receiving the same video signal (and hence running at same refresh rate and whatever).

the best way to measure would be with an oscilloscope, probing the video signal (or some signal inside the ...

Re: Measurement Device for Display Lag

Thanks for your reply!

We are aware that the Raspberry Pi is no ideal platform as it only supports up to 60 Hz but we decided to prioritize replicability over supporting displays with higher frame rates for now.
I think a completely open measuring method, including circuitry and source code is key ...

Measurement Device for Display Lag + Discussion of Lag Standards

Hey there!

My name is Andreas Schmid and I am a researcher for Human-Computer Interaction.

I would like to share an approach for measuring display reaction time using a device based on off-the-shelf components, which was developed as part of a bachelor's thesis in our research group.
