Idk about that. I'd rather stick to measured nits.

I understand what your saying. But then I dont understand how the Chinese guy from https://www.youtube.com/watch?v=eRpmxv7vaIk did not see any difference in ULMB2 off ( 446 nits) and ULMB2 on (347 nits) .
On the PG27AQN the percieved brightness difference between ULMB2 off 492 vs ULMB2 on 275 nits was HUGE. The 275 IPS PG27AQN nits differed aloth also with the 330 TN nits of the Zowie Xl2566K.

We need more inside information! The Chinese guy was not enough! I hope the monitors launches soon in the rest of the world!

Could be anything really: 446 vs 347 is not significant so he could of just quick checked and not pay enough attention, some are more sensitive than others, different reviewer different measurement, measurement errors, maybe you tested lower pulse width which result it lower brightnes...

Interesting.. I appreciate your input! ty!

Why do you need maximum brightness in games? It ruins your eyes, kills your vision. Dyac and maximum brightness ruin your eyes. Thus, people become blind by the age of 30 and are forced to buy glasses.
Doctors recommend using a brightness of 150 cd/m².
This is enough to see any objects in games.
You're used to cranking up 1000 cd/m2, it's like a flashlight pointed at your face. You can't use the monitor like that.

Find me one LCD monitors ( IPS/TN ) that show all stuff in dark area or on dull maps correctly with 150 nits or below without you having to strain your eyes to see something and after that, maybe you will be right.
It also depends on your ambient light, your sensitivity to light, your eyes and your vision.
Having low brightness especially for FPS games is just laughable and bad for the focus of your eyes and can reduce your reaction time if you didn't see correctly, anyway having 500~ nits is useless and nobody do that obviously but 400/380~ nits is very good.

Afterwards I know that certain monitors ( mostly with IPS panel ), because of how they work and also the poor contrast ratio, can turn out to be more dazzling than VAs for example which seem less flashy.

Besides, a very simple example, because of the lack of contrast on the Acer XV272UX, even at full brightness, you see less well than an Odyssey G7 in certain places in COD Cold War (for example) all this because the G7 highlights the elements better and no need to increase the brightness to see better but on some monitors you feel obliged to do that.

Fact, yes.

Brightness is a logarithmic behavior for vision, as well as ambient lighting.

1. Humans need geometric brightness differences to see a difference without seeing the displays side by side. Think "percentage differences" rather than "absolute X nits differences". e.g. 90-vs-100 nits or 900-vs-1000 nits is hard to tell apart standalone without the brightnesses being side-by-side to compare. But 20-vs-100 and 200-vs-1000 is easy to see.

2. Ambient lighting. 1000 nits in a bright glass condo during sunny daytime is less bright than 400 nits in a basement apartment with lights out and no windows. 1000 nits is not going to kill your eyes if you're forced to work in a sunny room.

These (1) and (2) are absolute facts.

Even other factors exist too, such as light spectrum and ergonomics. Light spectra (e.g. LCD backlight differences) are often a bigger ergonomic/headache/eyestrain issue, sadly -- which is why there is a boom of low-blue-light features, even though those aren't as effective/efficient as using tinted computer glasses (due to their inability to reduce blue light from darker colors, due to LCD greys being unchangeable color). And, I noticed with my own eyes, that 400 nits of better white light (e.g. the broad-spectrum white light from the white subpixel of a WOLED) feels less eyestrain than 200 nits of heavy-blue-LED-backlight. That's another unanticipated win for the weird W subpixel...

Something I wonder about re: reducing eye strain is replacing LED backlights with higher-CRI bins
There are LEDs these days humming along at 99+ CRI. The chief difference between these LEDs and normal ones is the amount of blue light and red light emitted (blue is lower, red is higher.) It's a big problem with LEDs since almost all white LEDs are principally based on a blue LED with phosphor layered on top to change the color.

High vs low CRI:



There used to be a small-batch ecommerce lightbulb company that would do this for you, you sent them a monitor and they replaced the backlight with super-high-CRI violet pumped Nichias, never seen one in person or seen it tested though.

That's an interesting route, it would be good to see more researchers work on exploring display-ergonomics.

I do pay the premium for high-CRI light bulbs at home. My home lighting is now CRI 93+ minimum (low cost). Unless I dim them I can't tell the light spectra is different from incandescent.

Personally witnessed this monitor 2 weeks ago in a demo, and pushed it to 2880 and 3840 pixels/sec on the Test UFO video game panning test. Text was clear to read at 2880, and just slightly too challenging for my eyes at 3840, while the comparative 240 and 360 FPS baselines weren't even close.

Haven't had a chance to see a decent 360 Hz LCD or 240Hz OLED monitor in the same test, so I'll defer to others in case there are considerations between that and capping the frame rate in testing. 500-540Hz and <2ms sample & hold/response time benefit is absolutely there IMO.

I am very curious if the ULMB2 will darken the TN panel unlike how DYAC does NOT darken the screen on Zowies latest panels. I returned the PG27AQN cause the screen gets darker with ULMB2 activated.

DyAc Premium vs ULMB 2 at 100 should be similar according to reviews. I'd assume brightness will probably be same or very similar to PG27AQN.activated.

I had the PG27AQN for 10 days. Played extensively on it. Returned it cause ULMB2 darkens te screen. The screen is brighter with ULMB2 off. (Plus no custom res) energy saving mode was off. Situation is like this https://reddit.com/r/pcmasterrace/s/vifL5gSmPG

It's more complicated than that. We need to be exposed to outdoor (bright) lighting to help mitigate myopia and related health conditions that impact people with myopia. Modern indoor lifestyles have in fact seen a rise in myopia (near sightedness).

It's the contrast between a bright monitor/small light and a dark room that can cause eye strain issues, and strobing can cause eyestrain issues if left on for general usage.

Basically don't play too late into the night, and try to get outside during the day as it will keep your eyes healthy, not to mention the pineal gland benefits (sleep pattern) and vitamin D (though more seasonal in non-equatorial regions).
