I can confirm
1. Pulsar keeps pulsing 360 hz if you have vsync off and are rendering more than 360 hz
2. If it dips from above 360 to below 360 the transition is smooth with no visible flicker to my eye

For #3, there was a review that compared the 2 and said the 540 hz ULMB 2 looks clearer but this more crosstalk than pulsar

Did you see it pulsing at 360hz with ur mobile camera? Im quite sure mine didnt do that.

Does this mean that for CS2 i should have it uncapped and play at my 500+ FPS. But with PULSAR: ON, VSYNC:OFF, REFLEX: ON ?
And i should get 360hz puls that should be "1440 hz motion clearity".

I still dosnt really understand what settings i should use on CS2 when playing competitive. Can any1 point me in the right direction please?

On my smartphone I do see the screen is still pulsing using slo mo mode but I cannot confirm the frequency of the pulse.

You should alway disable V-Sync. G-Sync is only useful under 360 hz but 1% low matters matter. Enabling v sync or g sync adds input delay and latency. Higher hz = lower frame times. However response time is what matters. The blur thing i never noticed. I consider everything below 360 fps as low fps. Most comp games give 500-1000 fps on QHD and when performance matters over graphics. At high fps u cant even track whats happening on monitor cause of 360 hz lock and pixel response cant keep up with frame time leading in no smooth gameplay. I personally dont see any improvement with Pulsar. What matters is response time, app latency and input lag with frame consistency. When i cap my fps at higher than monitor max hz i get tearing and lag than when its uncapped. But g sync is useless and Pulsar only useful around 240-300 hz and my 1% lows are higher already lmao. Motion clarity doesnt mean responsiveness. It can still feel like 60 hz even though it has no blur (clarity of 1000 hz) at the cost of tearing, trials, crosstalk and smearing. For desktop usage, lets say notepad or whatevzr its capped at 60 hz mode anyway. But vsync doesnt add but input lag and only works below that.

Im confused. Pulsar doesnt seem to be for competitive play (where u get stable 500-1000 fps on QHD low) as it doesnt add anything but input lag, latency and overshoot above 360 hz?

Why u recommend ULMB2 only then ?

Isnt OLED faster and smoother above 360 hz due to responsiveness and pixel transiton?
Idc if enemy is blurred as long as pixels are accurate but IPS is way too slow and laggy with tearing and artifacts at high fps…
G sync is recommended to be OFF for comp.
Imo pulsar is not for esports, even Marvel Rivals isnt that demanding to get not a stable 360+ fps with line 5070 ti and 9800x3d.
I can clearly see diff between 480 and 360 fps. When i went from 240 to 300 it was also a boost

So 800 dollar is a waste ? Wait for QHD 400-500 hz IPS monitors

Kinda disappointed with the refresh rate, We should be getting at least 500Hz in 2026.
I could only imagine how clear it would look like:(

There are dual mode 2K 500Hz/1000Hz LCD coming next year.
Battle between smoothness vs motion clarity

QHD already has noticeable text fringing on 27” cause its low pixel density and no pixel perfect scaling (unlike 4K 163 ppi) so full HD on Dual mode is fully blurry and pixelated with artifacts.

IPS QHD 500 and 600 hz (LG) are announced, but the main issue will always be the response time and unstable frame paces and . The advertised 1 ms is a joke and i dont wanna deal with overshoot and (inverse) ghosting which is still the case on even the best and fastest QHD IPS rn

Motion clarity of 1000 hz doesnt mean it will be as fast and smooth as a 1000 hz monitor dude. G sync only works under 360 hz on this monitor and adds input lag and latency. Check blurbusters forum for measured data. Theres also crosstalk on 360 hz mode over 240 hz. As the fps increase past 360 hz the monitor pixel response cant keep up and not overshoot enough to match the lower refresh rate. IPS has slow response time in reality to actually benefit. Measured data, not marketing. Motion clarity means eliminating blur but this is only the case where VRR + elmb 2 are enabled and they pulse at 360 hz above 360 fps. Its useless if ur fps is stable 500-1000 fps and adds system latency as measured.

Comparing response time of 2-6 ms (at effective 1000 hz IPS) to instant response time without ghosting of OLED is dillusonal tbh. OLED is way smoother and faster pixel response time despites the blur which is not relevant when u need to track down enemy where IPS cant due to slow response time and overshoot or low refresh rate compliance

The 2025 Asus QHD IPS ACMS 320 hz has 0,3 ms over 1 ms lol. And now asus claims their Pulsar is the fastest. I am so confused lmao.

Higher hz loses its benefit if response and frame time cant keep up.

I feel like there's a lot of circuitous conversation that's mostly opinion, and I'd like to get back to the actual monitors, not just speculation and heresay. (To say that comp games only run at 500-1000 FPS is ludicrous). Furthermore to imply that you should NEVER use V-Sync is also wrong. As far as I can recall, you've always had to use V-sync set to "on" in NVCP when using G-sync. If you don't like G-sync, why are you even posting here? Pulsar is specifically about marrying G-sync with Strobing. Everyone who's actually seen it seems to love it, even the one guy who hated it at first, now reports that he can't go back to OLED. So the advice that "no one should ever use any type of sync" is just kinda wasting everyone's time here. It's like going to a forum about award-winning cheese and telling everyone that all dairy is bad for you.

I'd like to know about the COLORS of these panels compared to OLED/QDOLED

I'd like to know about the panel BRIGHTNESS in bright environments

I'd like to know about brightness while using PULSAR

I'd like to know how the HDR modes look

I'd like to know how the HDR modes work with Pulsar?

CAN HDR even work with PULSAR?

I'd like to know about the brightness using the ambient light sensor, on the Asus, on the MSI, on the Acer, and on the AOC

There's a lot more to monitors than everyone running in circles spouting questionable technobabble.

If you are not going to use a VRR monitor for low latency v-sync, why would you want one?
As far as I'm concerned, it shouldn't induce any extra latency as long as g-sync is engaged.
Pulsar monitors are probably not what you want if throughput is your only goal.

Let's also remember that while esports bro's are a large initial audience for this monitor. There are plenty that like motion clarity for motion clarities sake. For us, it's more about returning to those CRT glory days than it is winning at esports (I play esports at a high level, yet I value motion clarity MORE than the sport).

We often are the type to really love smoothness, consistent frametimes, and clear temporal motion. I don't know if the gsync pulsar is the "next big thing" for that cause, but it seems like it might just be.

what's the actual difference, other than brand, between the four pulsar monitors currently available?

Acer Supports HDR600
AGON only has HDMI 2.0 looks like the rest have HDMI 2.1 (not really relevant I guess as you need DP for 360Hz pulsar anyway)

Some monitors may support the following Play at a more familiar 25ʺ diagonal size at 1080p, or enable Esports Dual Mode in the settings to play at an even sharper 2368 x 1332 resolution. With almost no perceivable latency difference in Dual Mode, as well as them supporting swivel/tilt and stands being different.

Beyond that I don't know

How come its not for games with high stable fps (+360)? If its motion clearity that i want. Isnt it better to use pulsar to get 4x the motion clarity?
Vsync on + Gsync on = 327 FPS, 4x pulse = Motion clearity of "1308hz".
What is the actual reason to not use PULSAR on games with +360fps, for example cs? In my understanding you will get way higher motion clarity with PULSAR enabled.

Because you lose the lower frametime / lower total system latency benefit.
Not only that, you get less total eye-tracked motion performance due to the lower frametime target.
You also get a severe potential increase in eye-strain, which is the biggest issue with these multi-strobe PWM solutions.

Pulsar is nothing more than VRR+Strobing. It's not some magic.
ULMB 2 = (fixed refresh rate) backlight strobing

However im playing cs competitive in high ranks and want the best settings possible. Both for latency and motion clearity. Do i get any extra latency when i use vsync + gsync + reflex?
How do i enable ULMB2 only instead? And what differs from using ULMB2 and PULSAR on cs2?

There is no latency overhead when you use GSYNC+VSYNC+Reflex.
Enabling Pulsar does result in a latency overhead due to the second pulse behavior.

You get extra latency when using vsync + gsync + reflex simply because more fps = lower latency.

Wrong, there is no total system latency overhead when using this scenario.

Using Pulsar or ULMB2 introduces a little bit of latency as well.
The question is does it bother you and are you willing to give up a very small amount of latency for better motion clarity. Some people are very sensitive to latency others not so much.

According to Battle(non)sense data, Pulsar does increase the total system latency.
No information about ULMB2, however. You cannot extrapolate information based on other backlight strobing implementations.
Latency is always a detriment to computing. It's not a "small amount" in the slightest.

The question is, does this scenario ( vsync + gsync + reflex) result in increased latency as opposed to totally uncapped frames + reflex? The answer is yes it does, very slightly. We're talking 1ms or less difference though. You can test that yourself in a game like cs2.

I've been using ULMB2 for over a year, there is no doubt ULMB2 adds some degree of processing latency. But that's been the case with all other backlight strobing techs as far as I'm aware of (dyac, elmb, ulmb). There are plenty of people, I would wager most people actually, that would simply not even notice a 3 or 4ms increase in total system latency. So it certainly is a "small amount" for those people at least.

And I care about microseconds added, which is why I said that it's not "increased latency".
I think you don't understand how VRR works, hence your claim of it adding any processing latency.

On the Pulsar panels, there's no 'added latency'.

Funnily enough, CS2 performs better when you do GSYNC+VSYNC+Reflex (encapsulating your general frametime).
I believe you need to distinguish the 'tearing' portion of fixed refresh rate from actual lower total system latency.

As for purely ULMB2, It's heavily model-dependant.
You can take a look at ULMB2 data we have:
