Predator X45

Reviewer verdict

Across 15 YouTube reviews, the Acer Predator X45 earns an Index score of 4/5, ranking #20 among Gaming Monitors. Reviewers most often praise its size & resolution, image quality, gaming features, while the most common criticisms concern image quality, size & resolution.

The Predator X45 is widely praised for its massive 44–45.5 inch 21:9 ultrawide OLED panel and aggressive 800R curvature, with many reviewers (41 mentions) saying the size and curve deliver an immersive, wraparound feel and lots of usable screen real estate. Reviewers also consistently highlight excellent image quality (31 mentions), noting OLED deep blacks, vivid colors, wide DCI‑P3 coverage, and strong factory calibration. Gaming‑focused features and performance are frequently mentioned (26 mentions each), including a very fast 240 Hz refresh experience, low response times, and support for variable refresh technologies that produce smooth gameplay. The monitor’s feature set and connectivity (17 and 13 mentions) such as multiple color profiles, USB‑C power delivery and a built‑in KVM are also commonly appreciated as making it a capable all‑in‑one gaming and productivity display.

Critics repeatedly point to problematic brightness behavior and uniformity (20 mentions), reporting aggressive automatic brightness limiting, fluctuations, and low full‑white brightness that can harm HDR/SDR consistency and text legibility. Several reviewers raise concerns about the panel’s effective resolution and pixel density (12 mentions), saying the 3440×1440 implementation yields relatively low PPI, subpixel layout issues and softer text compared with higher‑resolution displays. Price and value are also frequent negatives (9 mentions), with multiple reviewers calling it very expensive and noting a short warranty for that price tier. Other recurring drawbacks include OLED burn risk and PWM-related sensitivity (5 mentions), limited HDMI/video port choices on some units (4 mentions), and a few ergonomic/design annoyances like a large stand and always‑on power LED.
