What we like about the Acer Predator X27U W1 QD-OLED gaming monitor
Detailed 2560 x 1440 resolution
The WQHD resolution provides a useful middle ground between 1080p and 4K. Games receive a visible improvement in texture and object detail over Full HD, but compatible graphics cards can generally produce higher frame rates at 1440p than at native 4K.

Fluid 240Hz refresh rate
A maximum refresh rate of 240Hz makes movement appear considerably smoother than on standard 60Hz or 75Hz monitors. It is particularly valuable in competitive shooters, racing games and other fast-paced titles where rapidly updating visual information can make aiming and tracking feel more immediate.
Extremely fast pixel response
The specified 0.03ms grey-to-grey response time is one of the inherent advantages of OLED panel technology. Fast pixel transitions help minimise conventional motion smearing and trailing, producing clearer moving images than many LCD monitors even when both displays operate at the same refresh rate.
Excellent OLED black levels
Each OLED pixel generates its own light and can be switched off independently. Dark scenes can therefore contain genuinely black areas beside brightly illuminated objects without the blooming or grey appearance often associated with edge-lit LCD displays.
Wide and vibrant colour reproduction
The QD-OLED panel supports 10-bit colour and covers a claimed 99% of the DCI-P3 colour gamut. This gives games, films and HDR material a wide selection of available colours, while the stated Delta E below 2 indicates a useful level of factory colour accuracy.
Support for HDR10
HDR10 compatibility enables the monitor to display supported games and video with a wider luminance and colour range than standard dynamic-range content. OLED’s pixel-level lighting control is especially beneficial in scenes combining intense highlights with dark surroundings, although results depend on the content and selected display settings.
AMD FreeSync Premium support
FreeSync Premium helps coordinate the monitor with a compatible graphics processor, reducing tearing and uneven frame delivery. This is valuable at 1440p because demanding games will not always remain fixed at 240 frames per second, even when played on a powerful computer.
NVIDIA G-SYNC compatibility
Variable refresh rate support is not limited to AMD graphics hardware. The monitor is also listed as G-SYNC Compatible, giving users of supported NVIDIA GeForce cards access to synchronised gameplay within the applicable refresh-rate range.
HDMI 2.1 and DisplayPort connectivity
Two HDMI 2.1 inputs and two DisplayPort connections provide flexibility for a gaming computer, consoles and additional devices. HDMI 2.1 is particularly useful for modern consoles, while DisplayPort is the natural option for extracting the monitor’s full refresh-rate capabilities from a gaming PC.
Fully adjustable ergonomic stand
The included stand supports height adjustment, tilt, swivel and pivot movement. These adjustments make it easier to place the screen at a comfortable viewing height and angle, while pivot support allows the panel to be rotated into a vertical orientation when required.
Useful 26.5-inch screen size
A 26.5-inch viewable area works well with the 2560 x 1440 resolution, providing good pixel density without making interface elements excessively small. The size also keeps most of the image within the user’s immediate field of view, which can be helpful during competitive play.
Integrated speakers
Built-in speakers provide basic sound output without requiring a separate desktop speaker system. They are convenient for system audio, videos and casual console use, although dedicated speakers or a suitable gaming headset will generally deliver greater bass, clarity and spatial definition.
Slim ZeroFrame design
A narrow-bezel ZeroFrame design reduces the visible border around the panel and gives the monitor a cleaner appearance. It can also make the transition between screens less distracting if the X27U W1 is incorporated into a multi-monitor arrangement.
Who should buy this 240Hz gaming monitor deal?
The Acer Predator X27U W1 is best suited to PC gamers who want OLED contrast and colour without moving to a demanding 4K resolution. Its combination of 1440p resolution, 240Hz operation and rapid response makes it equally relevant to competitive multiplayer titles and visually rich single-player games. It is also a practical option for someone connecting a gaming PC and one or more consoles to the same display. Multiple HDMI and DisplayPort inputs reduce the need to repeatedly exchange cables, while the adjustable stand helps accommodate different seating positions and desk layouts.
Users who spend most of the day working with static toolbars, spreadsheets or fixed interface elements should consider the long-term characteristics of OLED technology. Built-in image-retention protection can reduce the risk, but varying content, allowing maintenance cycles to complete and avoiding unnecessarily high brightness with static imagery remain sensible precautions.
