NVIDIA G-Sync Pulsar monitor - Asus ROG Strix XG27AQNGV

[liquidshadowfox]

Recent nvidia drivers after 610.88 has been horrible for me with terrible stutters and frame pacing issues with Gsync + vsync + low latency mode = on which ruins pulsar. Hopefully nvidia fixes it soon because I can't update my drivers as a result and some of my games look terrible now with pulsar on because of the terrible stutter (wuthering waves, arknights:Endfield with x3 frame gen and 120 fps base fps enabled for example).

I think @kyube that at best we could only see maybe 1 "extreme" pulsar mode (if at all) given it would probably be very intensive for them to implement multiple pulsar levels given they really refused giving us a "variable pulse width" when we asked. I hope they at least give us a pulsar "extreme" mode with 1/2 the duty cycle across the board (thus half brightness) for better clarity and less brightness (I think it's too bright). Want to re-iterate, still enjoying my pulsar monitor as is! Wish they'd crank out some more stable drivers and give us a pulsar "extreme" mode as a "nice to have"

Does this monitor have a setting similar to the sharpness on the Zowie? And can i use strobe without vrr?On fixed hz ?

Yeah, it has ULMB 2. The strobing works on fixed refresh rates like 60, 120, 240, and 360Hz, though they might add more in future updates.

As for G-SYNC Pulsar, it does VRR and backlight strobing at the same time between 75Hz and 360Hz. Normal strobing breaks down when your FPS drops, but Pulsar keeps motion looking super clean even if your framerate fluctuates during games.

I grabbed a few comparisons from an online review. Here is the ULMB 2 vs Pulsar vs OLED comparison, followed by a look at Pulsar at 96FPS versus OLED at 360Hz. If you check out the motion tracking shots, you can actually see that Pulsar running at a lower 96FPS ends up looking super close to an OLED at 360Hz:

Nope it doesn't even a sharpness setting, lol . Yet I have 3 other cheaper Asus monitors with there sharpness setting, one is 1080p, one is 1440p and another 4k/1080p dual mode, vivid pixel, and the more expensive 1080p 610hz has vivid pixel as well

Pg248qp 540hz, pg27aqn 360hz and this monitor all ulmb2 monitors don't have basic qol setting like a sharpness slider

[Ziehesh]

This monitor look perfect.i have zowie xl2566k ,and dont know switch to asus or no.I very need sharpness setting in asus menu,but he dont have it ,i can try use sharpness from driver.What about input lag with vrr and pulsar ,better than zowie ?

nice dude ty. I switched to ulmb2 now for testing purpose. pw 20. is there a consensus for the best setting for high fps shooters?

nice dude ty. I switched to ulmb2 now for testing purpose. pw 20. is there a consensus for the best setting for high fps shooters?

Honestly, just use whatever you prefer from 120 FPS and up. There's no real consensus because a huge chunk of this high FPS obsession is just pure marketing and placebo anyway.

This monitor look perfect.i have zowie xl2566k ,and dont know switch to asus or no.I very need sharpness setting in asus menu,but he dont have it ,i can try use sharpness from driver. What about input lag with vrr and pulsar ,better than zowie?

99% of people literally can't notice a 1 to 2 ms difference in monitor latency. We’ve all been sold this lie that if you aren't hitting 720+ FPS you're at a massive disadvantage, when in reality, it's just self-suggestion pushed by brands so you keep buying hardware you don't need.

It actually reminds me of that classic story with Valve and CS back in the day. Players kept spamming forums complaining about bad ping even when servers were fine, so Valve's devs just updated the scoreboard to magically show a few ms less ping than it actually was. The connection didn't change at all, but the placebo effect went crazy. People flooded the forums praising Valve for fixing the servers and swearing the game felt super smooth. Total mind games.

Stepping away from the ultra-high FPS chase to use a G-SYNC Pulsar monitor has zero downsides. You can play anywhere between 75 and 360 FPS and actually get real benefits from it:

• Smart tech beats brute force: Features like G-SYNC Pulsar and ULMB 2 prove that motion clarity comes from smart backlight tech instead of raw power. Since Pulsar works dynamically from 75Hz all the way up to 360Hz, you don't even need a locked framerate. When frame drops or stutters happen, you don't notice them and everything stays smooth, which is something only this tech can achieve. As I showed in the comparison images above, even 96Hz or 120Hz with Pulsar looks just as clear as a 360Hz or 500Hz OLED. Whether you are playing fast competitive games or heavy modern single-player games, a mid-range or budget GPU from a couple of generations ago handles those 96 or 120 FPS easily, with DLSS helping out in newer games.
• Zero OLED headaches and better colors: If you are thinking of switching from old TN panels like the Zowie XL2566K, you can finally forget about washed-out colors and terrible viewing angles. On the flip side, OLED monitors strain your eyes, come with an annoying VRR flicker that will drive you crazy within minutes, and carry constant burn-in anxiety. There is simply nothing else on the market quite like G-SYNC Pulsar, delivering vibrant colors, wide viewing angles, zero burn-in risk, and exceptional motion clarity so you can game for hours in total comfort no matter your refresh rate.
• Resolution: You can enjoy native 1440p on a 27-inch monitor, which is way sharper and more defined than 720p or 1080p on a 24-inch monitor, instead of lowering your in-game settings to absolute garbage just to chase useless FPS.
• Power consumption and wallet savings: You don't need to spend a fortune on top-tier hardware just to hit 720 FPS on 720Hz monitors for zero real-world benefit, all while your PC pulls 500+ watts.
• Real future-proofing: Thanks to G-SYNC Pulsar, you won't need to touch your PC components for years and years. When you look at 720Hz monitors that force you to buy expensive hardware, demanding a ridiculous RTX 5090 just to keep 1% and 0.1% lows stable and prevent stuttering from ruining your game, it makes G-SYNC Pulsar say: "Look what they need just to mimic a fraction of our clarity!" These displays actually surpass them in real-world motion clarity, handle any game genre effortlessly, and let you connect a console to use ULMB 2 without a problem.
• Perfect timing: These monitors launched right when PC hardware pricing got completely out of hand. Instead of blowing thousands of dollars upgrading your GPU, CPU, and RAM just to chase raw frames, you can get incredible visual smoothness for a fraction of that cost just by buying a proper display. NVIDIA actually nailed the timing here.

Anyone who claims that 1 or 2 ms ruins games is just repeating what they read online and falling for marketing hype and pure placebo. They're just convincing themselves a problem exists when it doesn't. Blaming imperceptible latency for playing poorly is just a poor excuse because they refuse to admit they're simply bad at the game, or that their own biological reaction time is the real bottleneck no monitor can fix.

[kyube]

99% of people literally can't notice a 1 to 2 ms difference in monitor latency.

You do realise motion blur is a artifact of latency, right?
"1 to 2ms difference" when you push 3-digit microsecond pulse on-time, like ULMB2 PW<50 does on, is an absurd difference.
99% is a hyperbole.

We’ve all been sold this lie that if you aren't hitting 720+ FPS you're at a massive disadvantage, when in reality, it's just self-suggestion pushed by brands so you keep buying hardware you don't need.

That's how sample & hold works. It's how reality works.
You require raw sample rate to be able to emulate analog reality with digital systems.
It's not a lie.
It's more the case that specific slower games don't need high FPS to eliminate motion blur, when discussing purely eye-tracked motion clarity
Phantom array effect & stroboscopic effect are a whole different beast to tackle & require much larger refresh rate values.

It actually reminds me of that classic story with Valve and CS back in the day. Players kept spamming forums complaining about bad ping even when servers were fine, so Valve's devs just updated the scoreboard to magically show a few ms less ping than it actually was. The connection didn't change at all, but the placebo effect went crazy. People flooded the forums praising Valve for fixing the servers and swearing the game felt super smooth. Total mind games.

Didn't know that, nice find

Stepping away from the ultra-high FPS chase to use a G-SYNC Pulsar monitor has zero downsides.
You can play anywhere between 75 and 360 FPS and actually get real benefits from it:

You are completely ignoring a myriad of issues, which I've outlined many times in this thread, that Pulsar still has.
I'll even reply to the LLM-like reply down below, because it's funny.

Smart tech beats brute force: Features like G-SYNC Pulsar and ULMB 2 prove that motion clarity comes from smart backlight tech instead of raw power. Since Pulsar works dynamically from 75Hz all the way up to 360Hz, you don't even need a locked framerate.

Whether you are playing fast competitive games or heavy modern single-player games, a mid-range or budget GPU from a couple of generations ago handles those 96 or 120 FPS easily, with DLSS helping out in newer games.

1.) Pulsar (VRR+PWM) doesn't solve macrostuttering. It solves juddering (which happens due to mismatch of refreshTime & frametime) & tearing (spatial artifact, also caused by mismatch between refreshTime & frameTime)
Normal VRR also solves this. In fact, fixed refresh rate can also solve juddering & tearing at the same time.

2.) Pulsar, from a eye-tracked motion clarity perspective, can look better than high refresh rate OLED in specific frame rate targets which are <2 ms pulse on-time (or +500Hz effective motion clarity)

Zero OLED headaches and better colors: If you are thinking of switching from old TN panels like the Zowie XL2566K, you can finally forget about washed-out colors and terrible viewing angles. On the flip side, OLED monitors strain your eyes, come with an annoying VRR flicker that will drive you crazy within minutes, and carry constant burn-in anxiety. There is simply nothing else on the market quite like G-SYNC Pulsar, delivering vibrant colors, wide viewing angles, zero burn-in risk, and exceptional motion clarity so you can game for hours in total comfort no matter your refresh rate.

1.) VRR Flicker on OLED is a overexaggerated issue and doesn't occur in all 2D/3D titles. For example: Apex, CS2 & other esports games don't have (visible to the naked eye) light flicker on QD-OLED.
It's highly dependant on technology (QD-OLED or WOLED)

2.) Burn-in on OLED is also a overexaggerated issue.

3.) Treating Pulsar as a lower ranked eye strain concern than OLED is hillarious, considering you strobe your nervous system with +1800 cd/m² nits for a relatively long duration pulse on-time (due to the curve being mediocre, as they're doing a brightness-first approach)

Resolution:You can enjoy native 1440p on a 27-inch monitor, which is way sharper and more defined than 720p or 1080p on a 24-inch monitor, instead of lowering your in-game settings to absolute garbage just to chase useless FPS.

Frame rate is the single most important visual fidelity upgrade you can do to digital content.
Calling it "useless" is hyperbole or pure ignorance on how displays work.

Power consumption and wallet savings: You don't need to spend a fortune on top-tier hardware just to hit 720 FPS on 720Hz monitors for zero real-world benefit, all while your PC pulls 500+ watts.

1.) Don't play shit games which pull a high amount of power during high FPS gaming
There are ~400 / 12k games sample size, which are +500FPS, according to my WIP +500FPS games list, where I've singlehandedly went through each title to see how it performs on modern systems.

2.) Phantom array effect & stroboscopic effect aren't solved without going into 4 digit refresh rate territory.
It's ridiculous to claim 720FPS has "zero real-world benefits"

Real future-proofing: Thanks to G-SYNC Pulsar, you won't need to touch your PC components for years and years. When you look at 720Hz monitors that force you to buy expensive hardware, demanding a ridiculous RTX 5090 just to keep 1% and 0.1% lows stable and prevent stuttering from ruining your game, it makes G-SYNC Pulsar say: "Look what they need just to mimic a fraction of our clarity!
These displays actually surpass them in real-world motion clarity, handle any game genre effortlessly, and let you connect a console to use ULMB 2 without a problem.

Just don't play improperly optimized games and you can suddenly enjoy 720FPS @ 720Hz?

Perfect timing:These monitors launched right when PC hardware pricing got completely out of hand. Instead of blowing thousands of dollars upgrading your GPU, CPU, and RAM just to chase raw frames, you can get incredible visual smoothness for a fraction of that cost just by buying a proper display. NVIDIA actually nailed the timing here.

Nvidia didn't nail anything.
They've released a overpriced QHD@360Hz LCD with a re-iteration of the PG27AQN's panel with nerfed ULMB2 behavior and a mediocre pulse on-time x VRR refresh rate range curve.
The market is simply that bad in regards to VRR+PWM, that Nvidia's implementation actually looks usable compared to competition.
I'm somewhat certain that Titan Army's DYDS 2.0, TCL's MPRT-PLUS or MSI's MPRT-Sync all have the either the same or a better curve than what Pulsar does at 1/2 or 1/3 the price point of Pulsar panels today.

Anyone who claims that 1 or 2 ms ruins games is just repeating what they read online and falling for marketing hype and pure placebo.
They're just convincing themselves a problem exists when it doesn't. Blaming imperceptible latency for playing poorly is just a poor excuse because they refuse to admit they're simply bad at the game, or that their own biological reaction time is the real bottleneck no monitor can fix.

I agree that users blame external factors far too early on, but it highly depends from what target the 1 – 2 ms difference is, what portion of the chain the difference is present in and the cadence of the difference (the assumption is that it's constant, but in real life it almost never is)

@kyube Fair point, nobody's saying raw ultra-high refresh rates don't technically help with motion clarity.

The thing is, look at how people actually play. In competitive games like CS2 and Valorant, everyone lowers their settings anyway. Gamers end up blowing thousands on high-end hardware just to feed 500Hz or 720Hz+ monitors and keep 1% lows stable, paying a fortune for barely any real-world difference.

And let's be real about OLEDs: staring at them for long sessions gives you serious eye strain, which is something you just don't get with G-SYNC Pulsar. Also, OLED text looks like garbage in Windows, and aggressive ABL dimming ruins brightness consistency. They're definitely not the silver bullet everyone makes them out to be.

That's why G-SYNC Pulsar is a total game-changer that handles any game you play effortlessly. You get insane motion clarity dynamically anywhere from 75Hz to 360Hz without the OLED flaws, without needing a 500W space heater rig or dropping a fortune just to avoid stuttering.

At the end of the day, the goal is the same: it's a race for the best motion clarity. Right now, NVIDIA G-SYNC Pulsar is in the lead, and it's going to stay that way for the next several years, like it or not, while the technology just keeps maturing.

Anyway, for anyone asking how G-SYNC Pulsar and its modes work, here is how DisplayNinja explains it in their review:

Motion Blur Reduction & Variable Refresh Rate

NVIDIA G-SYNC Pulsar monitors have four operation modes: G-SYNC Pulsar, ULMB2, G-SYNC, and Normal.

• To enable G-SYNC Pulsar: You need to enable G-SYNC in NVCP (NVIDIA Control Panel) and set your refresh rate to either 360Hz or 240Hz. Then, make sure the G-SYNC Pulsar option is enabled in the OSD menu.
• To enable ULMB2: G-SYNC needs to be disabled in NVCP and then ULMB2 enabled in the OSD menu. You can enable ULMB2 at 360Hz and 240Hz.
• To enable ULMB2 at 120Hz or 60Hz: You need the latest firmware version and to make sure the "Allow ULMB2 60Hz" option in the OSD menu is enabled.
• For regular VRR (variable refresh rate) performance without strobing: You just enable G-SYNC in NVCP and set Pulsar to "Off" in the OSD menu.
• For normal operation without VRR or backlight strobing: You need to disable G-SYNC in NVCP and set ULMB2 to "Off" in the OSD menu.

Requirements:
For G-SYNC Pulsar, you will need an NVIDIA RTX GPU (30-series or newer). With other cards, you can only use ULMB2 or regular operation (VRR on or off).

Hey thx for replying! I play Apex Legends at an constant 300 fps. Would u play it on ULMB2 mode or PULSAR?
