Overview

The X27 X1 sports a 27‑inch Quantum Dot OLED panel that pushes 3840 × 2160 resolution at a 240 Hz refresh rate, delivering 163 ppi pixel density. Its 0.03 ms gray‑to‑gray response time and Adaptive‑Sync support ensure buttery‑smooth motion for competitive titles. The display also hits 1,000 nits of peak HDR brightness, positioning it among the brightest OLED offerings. Calibration revealed a slight purple tint in grayscale steps, which required adjusting gamma and resulted in elevated highlights. The monitor offers extensive picture controls, including eight color modes and five gamma presets, allowing fine‑tuned color accuracy. While HDR switching is manual, users can emulate HDR on SDR content for added impact.

Design and Build

The chassis features a fully metal backplate and a 1.5‑inch slim profile, giving the X27 X1 a premium, minimalist aesthetic. Its stand provides 4.7 inches of height adjustment, tilt, swivel, and portrait orientation, all with firm, solid movements. The build includes a large footprint base, a metal headphone hook, and a cable manager for tidy setups. Connectivity is robust, with two DisplayPort 1.4, two HDMI 2.1, and a USB‑C port delivering 65 W Power Delivery. Internal speakers of 2 × 5 W and a 3.5 mm headphone jack add convenience, while the USB 3.2 hub supplies ample peripheral ports. The removable VESA‑compatible back further enhances flexibility for arm or wall mounting.

Performance and Features

In motion tests the X27 X1 ranked among the fastest 4K OLEDs, with input lag low enough to support frame rates above 200 fps on a GeForce RTX 4090. Adaptive‑Sync combined with a 0.03 ms response time eliminates ghosting, giving competitive gamers precise aiming. The panel’s 10‑bit color depth and DCI‑P3 coverage exceed 103 %, delivering vivid, saturated imagery. Calibration adjustments revealed a trade‑off: correcting gamma produced slightly dimmer highlights, but the overall image quality improved for most users. The monitor includes gaming‑oriented OSD features such as aiming points, sniper mode, timers, and a frame counter, enhancing situational awareness. HDR handling is manual, requiring users to toggle between Auto and HDR‑1000 modes for optimal contrast.

Value and Market Position

At a launch price of $899, the X27 X1 undercuts rival 27‑inch 4K 240 Hz OLED monitors, making it an attractive option for budget‑conscious enthusiasts. Its three‑year warranty and recyclable packaging reinforce Acer’s commitment to durability and sustainability. The combination of high refresh rate, rich color, and extensive ports positions it as a well‑rounded solution for both gaming and productivity. While the lack of built‑in LED lighting may deter aesthetic purists, the monitor’s performance and feature set compensate strongly. Future firmware updates could address the manual HDR switch and improve gamma consistency out of the box. Overall, the X27 X1 sets a new benchmark for value in the premium OLED gaming segment.
