Well, some notes on measuring technique:
Display cloning dont work well for this purpose, a clone source display should have about a frame less delay then cloned one. Use display panning.
Any browser based stopwatch timers are innacurate due to Vsync is forced in Windows and broswer. That's why browser-based measured results are always multiple to given frame time. It is innacurate but still can give an idea which mode is faster and which is slower.
You show in OSD that freesync is active. Disable it for display lag measuring purpose.
Nice, interesting notes there! Do u know any software who make this easier to test? Also, maybe isn't better for the chief to make a standalone software with the tests of testufo.com ? Since the browsers always have issues here and there...
Edit: So, after reading some posts from the Chief, the article gsync 101, etc... I came to a conclusion there's no way I can made tests precise enough. But I'll do some more tests anyway since they can provide at least some margin of error about the displays.
Seems that D-Port have more lag then DVI... I'm quite shocked honestly. This is a incredible hot topic with tons of info, it seems the Chief is working for a substitute to the SMTT 2.0, which is great... As soon as I can I'll post some more videos. This time with freesync off and panning videos (still browser tests though since I don't have a clue of how can I test effectivelly). So I just got this video:
https://www.youtube.com/watch?v=e8ZtPSIfWPc and set to 2x timespeed. Panned the two screens, put the video in the middle and recorded.
Here are the tests:
144Hz

https://youtu.be/ZzzFpkRmhBY
https://youtu.be/UzIqwKSuIFs
240Hz
https://youtu.be/3v7kZWMdJU4
https://youtu.be/o1UQiYQsji0
https://youtu.be/wnS1KIXiwKU
https://youtu.be/0jLEE6olv-8
So, my conclusion (at least from this tests):
On 144Hz, the Benq is ALWAYS faster.
On 240Hz, the LG is faster EXCEPT on 1:1 Aspect Ratio mode.
Fullwide and Original seems to be about the same.
Not sure if this lag happens because of the display, or the cable, or whatever. Benq is on DVI-DL, LG on D-Port.
So, if you're planning to use freesync on high competitive gaming with low FPS, it seems not a great deal (still, much faster then the average display).
240Hz seems always great comparing to 144Hz. I'm not sure what people say about the "lag feeling", played as Ashe only on OW on one of my accounts since I got this display and the results are impressive:
https://www.overbuff.com/players/pc/dou ... ompetitive got almost 20k of heroscore being a Diamond pleb, which scores me at the top 4% on Overbuff, played a bit with freesync and the majority of the time with MBR off and 240Hz (fps uncapped). Even on this conditions (at least for me), I can feel a difference between 240Hz and 144Hz, to bad my setup can't hold 200FPS + all the time, so I'm not sure where is my threshold, but feels incredible snappy and smooth to track targets, so that's my anecdotal evidence regarding my feeling about the display.
