• Separate toggle for ULMB2 & Pulsar (like every other display on the market)
• Ability to push <10% duty cycle across the specific set of fixed refresh rate targets (60, 120, 240, 360); foregoing brightness for absolute clarity. Exclusively in rolling scan, not in global scan
From the comments I've seen here, only the 60Hz mode has this option right now.
Higher refresh rates make it easier to achieve the same strobe 'on' period at a higher brightness level.
• Pulse height (brightness / amplitude; NOT voltage boosted amplitude) is adjustable in both modes, I believe. Pulse width is only possible on ULMB2, but from all comments in this thread, it doesn't seem to be targetting a low duty cycle...
If we'd have the ability to push a low pulse width, we could get 0,125ms @ 360Hz @ (extremely low) brightness setting, akin to the PG27AQN
• 'Shape adjustments' (rolling scan vs global scan) are unnecessary. You want rolling scan for less eye strain in the first place.

Though, once TFTCentral releases their article to the public, I'll see what they've specified in there.

You can already set pulse width at 10 in all the ULMB2 modes (60, 120, 240, 360hz) it looks clearer and works.
60hz just looks better because of the pixel transition times I think.
Its also already a rolling scan.

On these tests:
https://testufo.com/ghosting#pps=2880 && https://testufo.com/ghosting#pps=3840
360Hz @ PW=10 should completely obliterate 60Hz @ PW=10 in terms of eye-tracked clarity.

From how I understood, that's not true in practice, which suggests that 60Hz has a different implementation (duty cycle range is larger, perhaps?) than the other fixed refresh rate targets (120, 240, 360)
The separate 60Hz toggle also implies that the implementation is different.

You can make a G-sync on off toggle using 2 bat files and this program:

Quick way to flip from Pulsar mode to ULMB2 mode with a double click.

To my understanding this only turns off or on Gsync, can it set refresh as well? I don't see that listed anywhere, at least that way we'd just need a program to check what app is in the foreground and toggle the highest priority mode. I wish there was a way to disable gsync natively on these monitors... pg27aqn is forced into gsync mode but I want it in ULMB 2 mode but I want pulsar enabled on my other monitor.... but I can live with having everything on the same gsync mode, just want to make Gsync toggle to off and set the max Hz based on the application/game launched so I don't have to fiddle around with a silly monitor OSD, this stuff should really be automatic.

I have this device that is used for lag testing systems specifically for smash melee setups on pc (Button press to average 0-80% transition completion). Kinda similar idea to the LDAT. I'm sure an actual oscilloscope would be better, but this is the persistence of the 60hz ulmb mode 10PW vs. my Sony E400 CRT measured on a lossless adapter.

It seems to report the ULMB pulses around 1800nits. Take that with a grain of salt, this thing is meant to be a gamecube adapter with a lag test feature, not a calibrated display tester
