so the new pulsar monitors have the same rolling strobe like zowie and few others

G-SYNC Pulsar pulses at 25% of a frame time. And the pulse happens right before the next scanout, right before pixels are overwritten with the next frame.
Above, you can see Pulsar behavior next to a traditional display. At 250 FPS with Pulsar, you get the effective motion clarity of a theoretical 1,000 Hz monitor.

I think it is very good review of pulsar. The only thing I missed was a comparison of PULSAR 240hz vs DYAC 2 240hz. This would help hide GTG transition on DYAC 2 which is not the best at max hz.
Another he missed in review is "UFO TEST MPRT INDICATOR" . Using it he could confirm that PULSAR HAS 1000hz equivalent motion to eyes.

Even though I currently have a pg27ucdm monitor(also had pg27aqdp), really looking forward to trying this monitor for both single-player and competitive gaming. It looks really cool.

Think strong pulsar advantage is almost no cross talk in any scenario.

I currently have a ViewSonic XG2431. I'm wondering exactly how clear (as in motion clarity) the image of these new Pulsar monitors are at a low fps (for example 75 Hz) compared to the XG2431. I know the strength of Pulsar is the almost negligable crosstalk, but in terms of just clarity is it just as clear as the XG2431 at such a low framerate? Maybe the Chief knows.

In review he says that nvidia recommeds turning on PULSAR on 90+ Hz but you can manually set pulsar to kick in from 75hz

EDIT — 13th March, 2026:
Firmware update added adjusable pulse width & a 60Hz single strobe mode
Performance of it is unknown thus far.

There's no necessity to upgrade to any Pulsar display if you already own the XG2431, as the Viewsonic's fixed refresh rate BL strobing is far better in customizability & therefore benefits to the end-user.
Though, there's an arguement to be had for G-SYNC Pulsar displays. Namely...
Positives:
+ Wide color gamut QD WLED backlight (QD vs YAG phosphor of the Viewsonic)
+ Rolling scan (anecdotally milder than XG2431's global scan in terms eye comfort) multi-strobe PWM (see edit above for single-strobe)
+ Increased pixel density over 24" FHD, though only slight benefit
+ Great G2G RT performance @ 360Hz setings as per OSRTT data, rivaling TN's and easily beating any IPS LCD on the market.
+ Adjustable pulse width in fixed refresh rate mode with the new firmware update added on March 12, 2026, as per this
+ 60Hz single-strobe with adjustable pulse width, as per link above.

Negatives:
– Increase GPUTime due to higher image resolution (1440p)
– VRR+Strobing (multi-strobe PWM) has a higher eye-strain potential compared to standard rolling scan backlight strobing (single-strobe PWM). In terms of 'potential' (highest to lowest): Multi-pulse global scan > Multi-pulse rolling scan > Single-pulse Global scan > Single-pulse rolling scan > standard sample & hold.
– Locked down to a Nvidia GPU. AMD GPUs don't work with Pulsar, as per MSI's manual.
– Locked down to the DP1.4 port, rendering it useless for console use.
– “HDMI 2.1” is not running at FRL6, but at TMDS (HDMI 2.0 BW), rendering the port completely useless. Confirmed by reading ASUS & MSI's manual.
– Permanent use of DSC due to forced DP1.4 requirement, which can break MPOs & thus affect performance in games negatively. Especially D3D12 games.
– ULMB2 mode (GSYNC off in NvCPL & Pulsar toggled on) doesn't seem to be using a fixed 25% pulse width, though oscilloscope data might change this point. [THIS IS PRE-FW UPDATE INFORMATION]
– High price point for 2026 market, where 24.5" QHD 300Hz costs <300eur. Pulsar isn't worth the ~750eur asking price, where OLEDs exist. The price point is the same as the PG27AQN, which came out in 2022
– Increased total display latency, as per Battle(non)sense's data
– ULMB2 & Pulsar(VRR+ULMB2) options are fused together and the former is (seemingly?) bugged in terms of clarity, not targeting a fixed 25% PW, as per here & later posts in this thread.

Neutral (subjective)
• Personally, <240Hz (4,1667ms) is a 'unusable' MPRT target from a fast-paced gameplay perspective. It's not worth exposing your nervous system to flicker when the MPRT (strobe on period) value is at such a (relatively) high target.
• Missed opportunity to incorporate a MiniLED backlight, which would allow for much higher voltage boosting & a lower MPRT target.
• Scaling of 27" QHD might be unappealing to some.


EDIT FROM THE FUTURE: This below estimation is very likely wrong as per this post
In terms of achievable MPRT (PULSAR is using a fixed Pulse Width of 25%) when using G-SYNC PULSAR (VRR+BLStrobing), we're looking at:
48 Hz — 5,2083ms (“Effective ~192Hz”) [lowest with Pulsar after the announced firmware update]
60 Hz — 4,1667ms (“Effective 240Hz”)
90 Hz — 2,7778ms (“Effective ~360 Hz”) [old low with Pulsar]
120 Hz — 2,0833ms (“Effective ~480 Hz”)
240 Hz — 1,04167ms (“Effective ~960 Hz”)
324 Hz — 0,771605ms (“Effective ~1296 Hz”) [(highest with Reflex cap, since VRR is enabled]
360 Hz — 0,6945ms (“Effective ~1440 Hz”) [if fixed refresh rate backlight strobing at 25% pulse width]

Considering that the maximum achievable brightness of most edge-lit LCD IPS displays fall within 300-400cd/m², we're talking about a brightness range of 75–100 cd/m² when using G-SYNC Pulsar (which uses a fixed 25% pulse width across it's 90–324 Hz range)
^ small addendum
monitors unboxed review discussing adjustable PW behavior


To me, ̶t̶h̶e̶ ̶f̶i̶x̶e̶d̶ ̶r̶e̶f̶r̶e̶s̶h̶ ̶r̶a̶t̶e̶ ̶p̶a̶r̶t̶ ̶ (see edit above) & higher pixel density is the most appealing aspect of the new G-SYNC Pulsar displays, as 24" FHD is a terrible pixel density target for the vast majority of desk depths.
The new G-SYNC PULSAR displays are the first QHD panels (since the 27" QHD 144–165 Hz G-SYNC Module models) which isn't nerfed with red fringing, due to the use of a QD WLED backlight.
I'm glad that they aren't using the KSF WLED like the PG27AQN had.

I'm hoping that the 32" 5K 165Hz panels will incorporate the aforementioned settings & a fixed refresh rate setting with adjustable pulse width.
They're seemingly going to be MiniLED based this time around

Glad to see one of my favorite youtubers back on track and testing Pulsar.

I know the strength of Pulsar is the almost negligable crosstalk, but in terms of just clarity is it just as clear as the XG2431 at such a low framerate? Maybe the Chief knows.

I don't see how these IPS LCDs could realistically avoid crosstalk. I'm sure the Nvidia overdrive and strobe settings are great but LCDs simply cannot remotely switch quickly enough. The edge cases and worst case scenarios will be prevalent and will take far more than the refresh cycle of the display in some circumstances.

I'm the last person to harp on refresh rate compliance because it's really not important with sample and hold but with strobing, slow pixel response times will absolutely entail crosstalk, especially at the high end of the refresh range.

I guess it wouldn't matter too much towards the low end of the refresh range but then you start to run into the flicker fusion threshold.

Testing will tell but I find it hard to get too excited about LCDs in 2019 let alone 2026.
