Those are definitely photoresistors. Interesting that you seem to get response times different than spec. Regardless, I strongly recommend photodiodes instead for various reasons including much lower response times, and less sensitivity to incident light. Then again, I've never used either so YMMV ...

I was just curious which photodiode so that I could look up its datasheet. Just like with any electrical component there are many parameters that can make a difference depending on the application. But I'm guessing their response times are typically in the ns or low us range anyway which is fine ...

Nice!

Interesting results and without knowing all the details, it seems pretty accurate and consistent at first glance.

I'm unfamiliar with the hardware and somewhat with the topic in general so forgive my ignorance, however, how did you arrive at the 10% "light level" difference threshold and ...

Don't forget latency gradients, as not all pixels refresh at the same time on the screen, www.blurbusters.com/scanout
This I knew. As long as the position of the photodiode on the monitor is the same, it should be okay. Especially since I'm mostly doing game tests, and those involve placing the ...

Hello. I've been trying to make something that would allow me to simply and properly test the input lag of my computer, and I have something I'm pretty happy with. I suppose I'm now looking for validation, and help on whatever I may be doing wrong ?
I plan on writing a guide on what to buy, and how ...
