But the Vicious Cycle Effect kind of applies here where 1440p is motion-blurrier than 1080p at the same refresh rate (higher resolutions amplify refresh rate limitations).
Physical distance wise 1314pps would be ~1:1 comparison, not 1440pps. Which is non-integer 3.65ppf for 360 fps, meaning impossible to compare properly. At least in this case. So perhaps better keep it fixed to pixels for now.

Vicious Cycle Effect may apply for unscaled content but from my understanding it doesn't really apply for gaming. For example in case of identically sized screens with differing resolutions, lets say 27", one with 1080p and other with 2160p resolution, physical on-screen size of in-game objects would be identical on both. Same object on 2160p screen would just take up more pixels to size match. And after we increase DPI to match sensitivity on the two (so more speed) the blur on both display would be ~identical because moving object size is "bigger". Scaling up the image and speed proportionally results in proportionally scaled blur. It's just that blur detail/resolution is finer on tighter PPI. So Blur Busters Law still applies here but since we increased object speed and object size the blur stayed the same.

It's a wild one. TestUFO could use an update.

Why on earth is there no ELMB or ELMB Sync mode on the ROG PG27AQN? Anyone got a good explanation? I have the current model (270hz) and it works very well so I was looking at this one as an upgrade but will hold off until they make an OLED 27 inch.

Charging nearly £1.2k for an IPS gaming monitor without that seems insane to me.

There's many ways to visualize it (screenwidth/sec, inches/sec, screentime, pixels/sec, etc).

Some of the perception issue is not necessarily dpi, but the amount of time an object is seen on the screen for -- that determines the ability to inspect its motion blur for an equal length of time, as a difference between static resolution and motion resolution. This gets muddy when we've got ultrawides and non-ultrawides. But when it comes to screenwidth/sec and time-onscreen, 1920x1080 and 2560x1440 is the same from that visualization POV.

That being said, testers need the choice of how they want to visualize the test, /within reason/ -- as long as fairly disclosed. And preferably over multiple metrics.

Yes, TestUFO needs an update. In fact, we're working on one already!

^ Ultra-fast IPS seems to be quite a jump from Fast IPS at 360Hz, and appears to finally have caught up with that refresh rate, for sure. Its overdrive performance in that capture rivals what I'm seeing on my PG279QM at 240Hz in the same scenario.

Considering how slow LCD GtG is evolving this is impressive for only one generation. Its lowest CAD on IPS so far. I'd like to see a cheaper "XG27AQN" model with same panel. That one would probably have ELMB/SYNC.

I wonder why they didn't tune the lower VRR framerate properly. Could of been much better.

Going to be super interesting to see this up against next year's 240Hz OLED tech. Very close race.

I'm a bit confused about the Asus PG27AQN's 25" mode.
It's a cool idea for gamers that play both single player and competitive games, but the monitor's 25" native resolution is 2368x1332 as opposed to 1080p.

So if I buy this monitor and use both modes, what res will I run my competitive games at? I keep them at 1080p in-game and allow the display to scale the game to 1332p for me ? Won't that add input lag?

You can use both 1920x1080 and 2368x1332 in desktop/game
