and NO more alt-tab black screens for me with exclusive full screen. It works so damn well now. Its amazing

Now that you have said that, it is really nice isn’t it. I would be playing in fullscreen and tabbing out with no black screen and I was assuming fullscreen wasn’t working in game and that it was just incorrectly staying in borderless all the time haha.

When I use 10bpc, part of the NVIDIA panel turns pinkish/white. That's not normal, right?

Also, is it worth using a 10-bpc when all I really do is play games?

Kyube, from my own testing with the same TestUFO patterns:

At 60 Hz ULMB, dropping the pulse width below ~30 gives a very noticeable jump in clarity (exactly as TFTCentral showed). It shows clarity difference across the whole PW range.
At 120/240/360 Hz ULMB2, lowering the pulse width slider has almost no visible effect on clarity — it mostly just dims the screen.

It really feels like the higher refresh rate modes are still locked (or limited) around the same ~25% duty cycle that normal VRR Pulsar uses, while only the 60 Hz mode got the full adjustable treatment.

To confirm we would need this test done at 120hz, 240 and 360hz modes. To my eyes the clarity stays the same across the whole pulse width range, or its a very subtle clarity change.

Even at 100, the improvement is huge.

True, but for some (for example for me) it's still unusable.


edit: I think I missed something important. So no adjustable pulse width for Pulsar, but Nvidia added proper 60Hz ULMB mode to Pulsar monitors? That's awesome. I mean, Pulse tech would've been better, but that's good. I guess I need to catch up with more than just recent 2 pages of this thread, sorry

I'm a fan of retro games. What they ask for Pulsar monitors is already too much, but such an overpriced LCD should have perfect 60Hz mode clarity, period.
Unless they start providing that, I'm postponing my purchase. Too many compromises. No OLED blacks, no OLED colors, no 3D and flawed 60Hz mode? No, thanks. I'd rather keep my two old XL2411s and save up for a VR HMD upgrade, which would give much better results in games. If only it had 60Hz at all, but I guess having an additional Quest 2 is some kind of a solution, if I block updates and pray it won't get bricked by faulty internal flash storage, cause outside of that Q2 + old firmware, there's no chance for 60Hz even in HMDs (head mounted displays). We're going backwards


For retro arcade games, there's something magical to how you perceive the game when you have razor sharp image in very fast motion. I refuse to give that up and I'd rather torture my eyes with 60Hz full screen strobe, than pick something significantly blurier.

The new firmware has 60hz support and adjustable pulse width.

But I think the adjustable pulse width in the 120, 240 and 360 modes is broken.

Retro games at 60hz look great on it, I don’t think there’s a modern display that does it better as it’s so bright.

Honestly if nvidia updated pulsar to duty cycle of 20% instead of 25% I think it would look significantly better without ruining their algorithms too much changing from the original 25% imo. It would be 5x the motion clarity instead of 4x! I still think the higher refreshes are borked on the latest firmware, the images look blurry at higher refreshes past 200 fps vs how it looks below 120 hz (and there's the sharp double imaging happening between 100 - 200 hz on top of that).

on rtings I saw someone comment this below
"I’ve been extensively testing the XG27AQNGV across a wide range of settings and frame rate scenarios, and I came away disappointed.

Pulsar does reduce perceived sample-and-hold blur in specific edge cases, but in real gameplay the difference between ON and OFF is minimal. Above ~320 FPS it frequently stops engaging properly due to VRR window behavior, so in the exact high-FPS scenarios where competitive players operate, it often provides no tangible benefit.

The fundamental limitation remains the IPS panel itself. The advertised “1 ms” response time is a best-case gray-to-gray marketing figure measured under extreme overdrive conditions, often with overshoot artifacts. In real use, response times are significantly higher and more variable depending on transition, refresh rate, and overdrive mode. IPS panels rely heavily on aggressive overdrive to approach those numbers, which introduces inverse ghosting, overshoot, and transition inconsistency—especially above 300+ FPS.

Pulsar also disables variable overdrive, which means overdrive tuning no longer adapts dynamically to refresh rate. That results in either underdrive at lower Hz or overshoot and crosstalk at higher Hz. In practice, effective response behavior becomes less consistent, not more. I also observed refresh rate compliance inconsistencies, added processing overhead, and signs of short buffer-induced latency when combining certain sync modes.

With V-Sync ON + Reflex Ultra, the system hard caps at ~320 FPS and latency increases from roughly 4 ms to ~12 ms. 1% lows worsen and frametime consistency degrades. The behavior feels similar to buffered rendering, which defeats the purpose of a 360 Hz esports panel. In contrast, running G-Sync with a manual 357 FPS cap and V-Sync OFF or Fast results in better responsiveness, tighter frametimes, and no meaningful clarity loss.

Marketing frames Pulsar as a competitive advantage, but it mainly reduces perceived blur. It does not change panel speed, pixel accuracy, or transition consistency. Motion clarity on IPS remains limited by response behavior, not refresh rate alone. Crosstalk and ghosting become more noticeable once you push beyond ~320–350 FPS."

Is it true that dynamic overdrive is disabled with pulsar? could it be that's why it doesn't look as clear at higher refreshes?
