Acer Unveil the Predator XB273U F5 at IFA 2024 with 360Hz and G-sync Pulsar

At the IFA 2024 press event, Acer have unveiled their new Predtaor XB273U F5 monitor. This is their upcoming 27″ IPS gaming monitor which features a 2560 x 1440 resolution, a 360Hz refresh rate and support for NVIDIA’s new G-sync Pulsar technology. The screen uses the new MediaTek scaler that is a replacement to the traditional G-sync module, offering a range of NVIDIA G-sync features including this new strobing blur reduction backlight that can operate at the same time as variable refresh rates offering potentially amazing motion clarity benefits.

Acer Predator XB273U F5 Specs

Spec wise the screen will offer a supposed 0.5ms G2G response time spec (take this with a pinch of salt) along with a 1000:1 contrast ratio, 500 nits brightness (SDR), 550 nits peak brightness (HDR), 178/178 viewing angles, 8-bit colour depth and a wide colour gamut covering 90% of the DCI-P3 colour space.

The screen has 1x DisplayPort 1.4 (with DSC) and 2x HDMI 2.1 view connections. There’s a full range of ergonomic adjustments offered from the stand with tilt, height, swivel and rotate on offer. There are also 2x 5W integrated speakers.

G-sync Pulsar Details

Strobing the backlight at a frequency that is not fixed causes serious flicker—which, until now, had prevented effective use of the technique in VRR displays. For over a decade, NVIDIA engineers have apparently pursued the challenge of marrying the fluidity of VRR timing with the precise timing needed for effective advanced strobing. The solution was a novel algorithm that dynamically adjusts strobing patterns to varying render rates. NVIDIA’s new G-SYNC Pulsar technology marks a significant breakthrough by synergizing two pivotal elements: Adaptive Overdrive and Pulse Modulation. They call this “Variable Frequency Strobing” NVIDIA said at the event.

With Adaptive Overdrive, G-SYNC Pulsar dynamically adjusts the rate at which pixels transition from one colour to another, a vital technique to reduce motion blur and ghosting. This process is complicated by VRR technology, where the refresh rate fluctuates in tandem with the GPU’s output. G-SYNC Pulsar’s solution modulates overdrive based on both screen location and refresh rate—ensuring that clarity and blur reduction are maintained across a spectrum of speeds, and across the entire screen space.

Furthermore, G-SYNC Pulsar simplifies the user experience by eliminating the need to switch between different monitor settings for either VRR or strobing technologies. Whether it’s for the high-stakes environment of competitive gaming, or the rich, detailed worlds of immersive titles, G-SYNC Pulsar delivers a superior and convenient visual experience tailored to all facets of gaming.

Motion Blur Reduction Benefits

In the video below, a 1000 FPS high-speed pursuit camera recorded Counter-Strike 2 running identically on a 360Hz G-SYNC monitor with Pulsar technology enabled, versus with Pulsar technology disabled. Played back at 1/24 speed, the reduction of monitor-based motion blur on the G-SYNC Pulsar display is immediately evident, greatly improving clarity, fidelity, target tracking and target acquisition, helping improve hit rate, and more, making users more competitive online.

Reducing Flicker

Complementing this, the technology also intelligently controls the pulse’s brightness and duration—key to maintaining visual comfort and eliminating flicker. Flickering, often a byproduct of strobing methods used to diminish motion blur, can disrupt the gaming experience and cause viewer discomfort. By adaptively tuning backlight pulses in response to the constantly changing game render rate, G-SYNC Pulsar creates a consistent and comfortable viewing experience, effectively accommodating the display’s dynamic nature.

Merging these two adaptive strategies, G-SYNC Pulsar transcends previous challenges associated with enhancing VRR with strobing backlight techniques. Prior attempts have often stumbled, leading to flickering and diminished motion clarity. However, G-SYNC Pulsar’s innovation ensures perfect synchronization between overdrive and backlight pulse with the screen’s refresh cycle.

This represents a leap beyond incremental updates or a combination of existing technologies: it is a radical rethinking of display technology—necessitating the development of new panel technology, and representing a fundamental reengineering at both hardware and software levels.

The resulting gaming experience is transformative, where each frame is delivered with both stutter-free smoothness, and motion clarity that is effectively the quadruple of its baseline refresh rate—enabling a truly immersive and uninterrupted visual journey for gamers. Even in the most intense and fast-paced games.

Pricing and availability

The release date and pricing for this screen has not been provided yet, but the NVIDIA rep at the event stated that Acer would be “one of the first to market” which suggests it will probably be released in Q4 as that’s the announced timescale for Asus’ equivalent model. more info when we get it.
