This post inspired me to do the same test, in order to try and exclude the TD factor from my eyestrain. (the vimeo links in that thread are expired)

I wrote a html/js page that goes slowly from white to black and recorded it with the 480fps cam on my LG G5 phone. I used a cheap microscope attached to the camera.

Here is the result. (the first half of the video is uninteresting)

My setup is as follows:

- laptop (intel GPU) attached to an external monitor (Dell 2408WFP)

- the monitor is at max brightness, with no software blueblocking filters

- The intel GPU is configured with:

"Inbuilt processing by the display": Off (in order to avoid TD)

"YCbCr": On (in order to avoid TD)

"Quantization range": Default

- ditherig.exe is set to "no dithering"

So, do you guys think this flicker is TD? And can you give me any advice?

    logixoul Not sure what monkeying with those settings in Intel GPU settings does with regards to your tests.

        I have no account and can't watch the video:

            Good question! 🙂

            • The "quantization range" thing - probably nothing, but some forum members have reported that it's related to screenstrain, so I decided to mention it.
            • "YCbCr" (set to ON) has been reported to disable TD
            • "Inbuilt processing by the display" (aka the "IT Content" option) set to OFF has been reported to disable TD

                KM I just set a rating for the video - "All audiences". Should be viewable now. Sorry for the problem - I'm new to Vimeo 🙂
