Acer Ships ConceptD CP7271K P: A Professional 4K 144 Hz Monitor with G-Sync Ultimate

Acer has started shipments of its ConceptD CP7271K P professional monitor designed for developers of fast-paced color-critical HDR content such as animation, games, and movies. The monitor brings together a 4K Ultra-HD resolution, an accurate color reproduction, a 144 Hz refresh rate, VESA’s DisplayHDR 1000, and Pantone Validated certifications as welll as NVIDIA’s G-Sync Ultimate (former G-Sync HDR) variable refresh rate technology.

Aimed at color-critical workloads, the ConceptD CP7271K P uses a premium 27-inch IPS panel of a 3840×2160 resolution that features 0 nits native brightness, 1000 nits peak HDR brightness, a 1000:1 contrast ratio, a 4 ms GtG response time, 178° viewing angles, and a variable refresh rate of up to 0 Hz (that can be overclocked to 144 Hz). The professional monitor comes factory calibrated to a Delta <1 accuracy, it can display 1.07 billion colors as well as reproduce 99% of the AdobeRGB and 93% of the DCI-P3 color spaces (required by professionals working with today's digital content). In addition, it is Pantone Validated.

Gaming displays supporting NVIDIA’s G-Sync Ultimate technology feature a quantum dot-enhanced full-area local dimming (FALD) backlighting for ultimate color clarity and high contrasts. For some reason, Acer does not advertise either technology in case of the ConceptD CP7271K P (which does not automatically mean that it does not use similar technologies). Meanwhile, the monitor carries VESA’s DisplayHDR 1000 badge, so it has to feature not only 1000 nits peak brightness, but also at least 0.05/0.10 nits blacks (corner/tunnel) that require some kind of local dimming, according to VESA.

There is one important thing to point out about NVIDIA’s G-Sync Ultimate implementation on modern monitors. Formally, all of the displays carrying this badge support a 4K (or similar) resolution and an up to 144 Hz variable refresh rate. Meanwhile, since these displays connect to host PCs using a DisplayPort 1.4 interface with its bandwidth limitations, chroma subsampling is required beyond 98 Hz for 4K HDR content. That said, although G-Sync Ultimate LCDs feature a 0 Hz or 144 Hz maximum refresh rate, colors will not look best at these rates.

When it comes to connectivity, the monitor has a DisplayPort 1.4, an HDMI 2.0 input, and a five-port USB 3.0 hub. In addition, it has two 4 W speakers.

As with virtually all professional displays, the Acer ConceptD CP7271K P can be adjusted to its user’s environment and comes with a stand that can regulate height, tilt, and swivel. Furthermore, to guarantee consistent color quality, the LCD comes with a lighting hood.
