Has anyone done button-to-screen input lag tests for the BenQ XL2540 at 240hz?

I found some good stuff on 240hz for the Acer Predator here, but not the XL2540:

Here I found discussion on 60hz input lag tests for the xl2540 which seem pretty invalid.

I'm hoping to find some stats tested at 240hz with and without the hacked blur reduction...any help is appreciated. Or if this can be done DIY for <$100 I might be interested in to putting in some research and performing the tests myself. Thanks for any help/info.

If you just wanted to know the awnser I can tell you it's going to be as low as every other 240hz monitor, they don't really vary much interms of input latency.

But I think chief was going to make a sellable input latency tester device if I recall correctly, maybe I'm wrong.

That it can. Everything needed should be less than $50.
Microcontroller that can emulate a mouse(I used an arduino micro, flood used a teensy 2.0)
A basic electronics prototyping starter kit. (assorted resistors, LEDs, switches, jumpers, capacitors, and a breadboard).
An opamp.
A photoresistor, photodiode, or phototransistor. (photoresistor is slower, but simpler to implement)

Here's flood's thread, there is a post with his code somewhere in there, along with discussions about developing the testers: viewtopic.php?f=10&t=1381


Here is the post that explains how I built mine(including code), and there's more discussion in this thread: viewtopic.php?f=10&t=3005&start=50#p22634
