I'm leading with the CAD chart because I think it's the best overall metric for LCD performance; CAD penalizes both slow responses and overshoot. Lower is better.

With my new CAD computation, which I believe better captures the overall "quality" of an LCD's responses, the standout performer is LG's 24GM79G. Its CAD of around 30 comes from how quickly its gray-to-gray transitions converge to their targets.

The grouping of IPS displays in the middle of the chart, the VG279QM, the XG270, and the Y27q-20, perform well, but are all a bit worse than the TN panel. Slow-ish falling transitions are the primary cause. But it's fascinating to see how the Lenovo Y27-q20, which is a QHD screen, is performing right in line with the "fast IPS" 240 Hz displays.

The VG279QM is incredible at 280 FPS, and it can even perform better with its service-menu OD 120 setting.

The unusual rise in CAD scores at 85 FPS is due to the fact that NVIDIA's LFC either hasn't or can't kick in. The 165 Hz screens don't have enough refresh rate headroom to double the panel refresh (85*2 = 170). Scores drop back down at 60 FPS (other than the VG27AQ) because the panel is now refreshing at 120 Hz. This allows the overshoot to be corrected every 8.33 ms instead of at every 11.8 ms.
