For me G-Sync Off/Fixed Refresh + V-Sync Off has the lowest input lag and that's my aim/goal. I've tried it on my 360Hz and the 240Hz maximum with ULMB is terribly slow. And according to RTINGS the input lag with ULMB is 5.5ms vs 1.6ms at Native. I might try the 390Hz Acer AOPEN with ULMB to see how it is but for now it's Fixed Refresh & V-Sync Off

So all off. I did not know PG259QN had such input lag difference with ULMB.
On my VG279QM it felt the same or maybe even slightly snappier with ELMB.

According to RTINGS the VG279QM input lag is the same: both Native & ULMB/BFI @ 1.7ms, while VRR is 1.8ms. It's a fantastic monitor. I should of returned the one I had for a new one and used it for my daily/main rig.

P.S. Quick Frame Transport is a superior way to lower strobe lag. NVIDIA ULMB doesn't use Quick Frame Transport (QFT).
See New Quick Frame Transport HOWTO.

VG279QM doesn't use NVIDIA ULMB. It uses ELMB-SYNC. ELMB-SYNC already takes advantage of QFT automatically (as does all VRR technologies).

I also did not know QFT can affect it that much. Then it would be nice to see manufacturers state such thing.

VG279QM is proof of QFT doing wonders to strobe lag! (All VRR is defacto QFT).

Is that a different implementation? Why does RTINGS use BFI? Is that some sort of generic term for it?

Amazing stuff!

What is the largest possible VT panels can achieve these days?

Yes, "BFI" (Black Frame Insertion) is a generic term. Although this could denote directly black refresh cycles, it is also used to describe strobing as the backlight equivalent of inserting black frames.

It's a function of a panel's min/max Hz. See the FAQ. So get the max Hz available today on a 1080 panel (e.g. Acer 390Hz) and run it at min Hz (e.g. 50Hz or 60Hz). So you can increase VT by (390/60) times the VT of 60 Hz. Future 480 Hz panels doing 60 Hz may be able to support a Vertical Total of 9000. There's no upper limit except the LCD's panel to fade during excessively long refresh cycles, but if the panel still supports native 60 Hz despite a high Hz, then it can still continue to scale.

On the other hand, if you're looking for strobing you will have to adapt if minimum strobe Hz is high (e.g. 100 Hz).

Don't forget you need retro-friendly strobe support -- a mandatory feature of Blur Busters Approved 2.0 such as www.blurbusters.com/xg2431
