NVIDIA G-Sync Pulsar monitor - Asus ROG Strix XG27AQNGV

Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, ToastyX, black frame insertion (BFI), and now framerate-based motion blur reduction (framegen / LSS / etc).

Article makes a mistake anr says 1000hz clarity but the marketing says 4x. So rounded up 1500hz.
I wonder if that means 120hz strobed gets limited to 4x too or... Guess we will know in 2 months

4x Motion clarity. It could be rolling BFI.
Only 400nits of Brightness . It not sounds good for full frame BFI. But rolling BFI done in one frame could give more light

Please don't have a KSF phosphor backlight.

Good news, it does not have a KSF phosphor backlight.

This is great news for strobe fans!

That one video hinted KSF/PFS is no longer used for Pulsar, at least for the model used. viewtopic.php?p=118123#p118123

I am aware of the public rumors of the early prototype being KSF, but the production versions are not KSF. It's possible that old footage was possibly used.

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.

Unstrobed, 1000Hz OLED will definitely beat any unstrobed LCD

But this baby is strobed. Hz doesn't improve motion clarity of strobing. Motion clarity is dictated by pulsewidth. 360Hz ULMB does look clearer motion than an unstrobed 1000Hz OLED.

In fact, 500Hz strobing is worse than 360Hz strobing because of the refresh rate headroom trick to hide LCD GtG in the VBI. Discorz eloquently explains why lowering Hz sometimes improves strobing at www.blurbusters.com/xg2431-discorz because LCD GtG is too slow to avoid strobe crosstalk at a higher Hz.

So it's just a game of pick-poison compromises, but "how clear it would look like" isn't going to happen with a higher Hz strobed LCD, when the calculus for stroberate=refreshrate=framerate favours a Goldilocks Hz (not too high and not too low) when combined with low strobe crosstalk (Hz low enough to hide LCD GtG pixel response in total darkness between strobe flashes).
