The choice is primarily resolution and screen size: the Predator X32 X2 is a 31.5-inch 4K monitor, while the X27U X1 is a 26.5-inch 1440p model. Acer lists both as QD-OLED displays rated for up to 240Hz and 0.03ms GtG response time; those are published specifications, not independent measurements.
What’s the difference between the Acer Predator X32 X2 and X27U X1?
The X32 X2 gives you a larger 4K display; the X27U X1 offers a smaller 1440p screen. Tom’s Hardware’s March 31, 2025 launch report describes the two models with shared headline motion and picture specifications, but the resolution and size are the clearest practical distinctions for choosing between them.
| Specification | Predator X32 X2 | Predator X27U X1 |
|---|---|---|
| Screen size and resolution | 31.5 inches; 3840 × 2160 (4K) | 26.5 inches; 2560 × 1440 (WQHD) |
| Panel technology | QD-OLED, according to the 2025 launch report | QD-OLED, according to Acer Australia’s product listing and the 2025 launch report |

| Response-time rating | 0.03ms GtG, published specification | 0.03ms GtG, published specification |
| Color and HDR specifications | Launch report lists 99% DCI-P3 and DisplayHDR 400 | Acer Australia lists 99% DCI-P3 and DisplayHDR True Black 400; launch report lists DisplayHDR 400 |
| Video connections | Launch report lists two HDMI 2.1 ports and one DisplayPort 1.4 | Acer Australia confirms HDMI 2.1; launch report lists two HDMI 2.1 ports and one DisplayPort 1.4 |
| Stand and audio | Launch report says adjustable stand and two 2W speakers | Acer Australia confirms height adjustment, tilt and swivel; launch report says two 5W speakers |
| USB ports | None listed in the launch report | None listed in the launch report |
Specifications beyond the Australian X27U X1 listing are reported by Tom’s Hardware’s March 31, 2025 launch coverage. Acer’s regional listing is for the X27U X1, part reference UM.GXXSA.101, and confirms its Australian-market features.
Which one is 4K?
The X32 X2 is the 4K model, with 3840 × 2160 pixels across a 31.5-inch screen. The X27U X1 is 2560 × 1440 (WQHD) at 26.5 inches. That makes the X32 X2 the option to consider if your priority is the higher-resolution, larger panel; the X27U X1 is the smaller, lower-resolution alternative. The supplied specifications alone do not establish which will perform better with a particular PC or game.

- OLED Makes All The Difference: With a display of these mammoth-like proportions, everything must look good. The WQHD quantum dot OLED display with true 10Bit is obligated to offer stunning contrast, cinematic color. Image retention-refresh keeps the images from sticking.
- AMD FreeSync Premium Technology: Say “goodbye” to stuttering and tearing. With AMD FreeSync Premium, the monitor’s frames are synced with the graphics card’s frames, which eliminates screen tearing and provides the smoothest gaming experience.
- Fast and Furious: If you want seamless gameplay at ridiculous levels of speed, you’ve come to the right place. With an 240Hz refresh rate and 0.03ms (G to G) response time, your sessions will be fluid, unbroken and unmatched – with little to no ghosting.

The addition of a ZeroFrame design also removes the bezels – giving you have even more visibly over every match and every movement your rivals make.
Do both monitors support 240Hz, and what does 0.03ms mean?
Yes. Acer’s published specifications and 2025 launch coverage list both monitors at up to 240Hz and rate each at 0.03ms GtG response time. GtG means gray-to-gray pixel transition time. These figures are manufacturer specifications, not independent test results: they do not establish measured input lag, real-world response behavior, or that one model is faster than the other.
What do the HDR, color and connection specifications establish?
The launch report lists both displays with a 1,500,000:1 contrast ratio, 250-nit native brightness, a peak of up to 1,000 nits in a 3% window, 99% DCI-P3 coverage and DisplayHDR 400. These are reported specifications, not independent measurements. The peak-brightness figure is specifically tied to a 3% window, rather than a claim about full-screen brightness.
