Pursuit Camera Commentary [for above footage]: From the sync track point of view, camera exposure is incorrect according to camera-settings criteria. Dim the screen or use a professional camera app ("DSLRCamera" for iOS) to get longer camera exposures per freezeframe, in order to stack 2 refresh cycles per freezeframe. You'll get much worse images for mis-tracked freezeframes (multi images amplify a lot), but much better images for accurate-tracked freezeframes (it becomes more WYSIWYG). However, even 1-tickmark strobed pursuits are semi-useful to analyze -- especially strobe crosstalk analysis -- even if there's only 1 tickmark. Ideal pursuit camera footage should get at least 2, 3, or 4 tickmarks but can get difficult for end users, but a little more allowance is given for 1-tickmark pursuit camera exposures for strobed modes as long as it's done by end users rather than professional reviewers -- due to the way strobed modes have useful analysis even for stationary camera too

the moment i saw those guidelines chief, i immediately tested my viewsonic's backlight strobing. And my god, u weren't joking about that red tint. Damn, i guess the viewsonic gets an "L" here
Yeah, the XG270 is vastly superior to the XG270QG if you definitely want strobing.
I've written about this in
Nano IPS Red Phosphor Affects Strobing. Fortunately, this is generally not a problem when there is no backlight modulation. If you don't use strobing, then it generally does not matter -- the nice reds of the Nano IPS are beautiful. Stunning really.
But not everyone cares about color. Remember, 12% of human population is colorblind. There's different levels of colorblindness, similar to different levels of deafness. So they may see colors but not benefit as much.
Everyone has their reasons for preferring different panels. They might even have
motion blur discomfort / headaches / nausea where TN is better for them. Or they earn thousands dollars from lower lag in esports. Or they are super-sensitive to ghosting/coronas. I've seen people benefit more from TN than IPS. And I've seen people benefit more from IPS than TN. Just like not everyone sees tearing. Or microstutters. Or DVD versus HDTV (like grandma). Etc. Etc. Everyone sees different.
Bottom line, respect IPS. Respect TN.

Then again, look how clear the aliens are. THE MPRT is a good tradeoff for that overshoot.
Yeah. Not the world's best. Some TN panels are massively better than all IPS panels in low strobe crosstalk, when strobing is a high priority. But fortunately, certain IPS panels such as XG270 can successfully strobe straight into the TN ballpark! (Maybe not as well as 240Hz XL2546S at 240Hz, but it definitely does a great job at low-crosstalk 120Hz).

but what the heck is that blue thing behind that alien? is that crosstalk? pixel smearing? or just motio n blur trail?
It's crosstalk as explained at
www.blurbusters.com/crosstalk.
But it can include ghosting/corona style tinting.
Strobe crosstalk is essentially instantaneous chopping (brief interval flashes) along the GtG curve.
It's LCD GtG that overlaps multiple refresh cycles.
To understand "How Do Monitor Manufacturers Cram GtG between Refresh Cycles During Strobing To Reduce Strobe Crosstalk", please look at the high speed videos at:

We've been doing this for years, so we know this stuff!
