This post is partially outdated – please have a look at the updated version #33F3 with proper photo diode measurements as well!

 

So…I tried measuring response time of the monitor, and I didn’t really succeed. I’m missing MY PRECIOUS photo diode, so doing the same thing with an LED…is pretty meh. Don’t take these for real, time must be off due to high capacitance (“high” being some 10pF including leads?) and the LED not being as sensitive as a proper photo sensor diode.

Well anyway, the shape of the traces tells us a little about the AMA setting of the display, which is BenQ speech for the Advanced Motion Acceleration or pixel response / panel overdrive setting. […]
