The Acer Predator XB273U GS is a well-balanced 27-inch gaming monitor built around a combination that still makes a lot of sense: 1440p resolution, a 165Hz-class refresh rate, an IPS panel, wide color coverage, low response times, and a highly adjustable stand.
Its biggest strength is not HDR. Instead, this monitor is at its best when used as a fast and versatile QHD display for gaming, office work, video, and everyday desktop use.
For users with GPUs such as the RTX 3060 Ti, RTX 4060, or RTX 4070, the 27-inch 1440p format is particularly attractive. The combination of Acer Predator XB273U GS, 1440p, and 165Hz offers a good balance between image quality and GPU workload.
It is also a practical choice for a gaming laptop such as the Gigabyte AORUS 15 9KF with RTX 4060. The laptop can handle 1440p gaming in many titles, while the monitor provides a larger and smoother desktop gaming experience.
For users who are also interested in reliable power solutions for Acer equipment, an Acer battery can be an important part of maintaining older compatible devices. In other words, good display hardware and dependable power hardware both matter when building a long-term workstation.

One important detail is the model number. Acer’s XB273U family contains several versions. The XB273U GS should not be confused with the XB273U GX, which targets a much higher refresh rate.
1440p and 165Hz: The Sweet Spot
The biggest reason to consider the Acer Predator XB273U GS is its 27-inch 2560 × 1440 IPS configuration.
At this size, QHD resolution provides noticeably sharper text and graphics than a conventional 27-inch 1080p monitor. The pixel density is approximately 109 PPI, which works well for both gaming and productivity.
The 165Hz refresh rate is equally important.
Compared with 60Hz, 165Hz reduces the theoretical frame interval from approximately 16.67ms to just 6.06ms. Fast mouse movements, camera turns, racing games, and competitive shooters therefore feel substantially smoother.
For games such as CS2, Valorant, Apex Legends, Overwatch 2, Fortnite, and PUBG, the 165Hz monitor configuration is particularly useful.
The 165Hz monitor specification does not mean a game must constantly produce 165 FPS. Even 100–140 FPS can feel considerably smoother on a high-refresh display, while frame rates close to 165 FPS allow the panel to be used more fully.
IPS Color and Everyday Usability
The IPS panel gives the Acer Predator XB273U GS another advantage: it is not restricted to gaming.
The wide viewing angles make it comfortable for everyday desktop work, while the approximately 95% DCI-P3 coverage provides a richer color range than many older TN gaming monitors.
For gaming, movies, browsing, Photoshop, video editing, and general content consumption, the IPS monitor design is a strong all-round solution.
However, users working with professional color-critical applications should still calibrate the display or choose a monitor designed specifically for professional color management.
What About HDR?
This is where expectations should be realistic.
The Acer Predator XB273U GS supports VESA DisplayHDR 400 and offers around 400 cd/m² brightness, but it does not have the local-dimming capability found in modern Mini LED displays.
Its IPS panel also cannot match the near-perfect blacks of an OLED display.
Therefore, HDR gaming can look better than ordinary SDR in some situations, but this is not a monitor I would recommend primarily for HDR movies.
The better reason to buy it is the combination of:
- 1440p resolution
- 165Hz refresh rate
- IPS technology
- Wide color coverage
- G-SYNC Compatible VRR
- Flexible ergonomic stand
Think of HDR as an additional feature rather than the main selling point.
G-SYNC Compatible and RTX 4060
The 165Hz monitor configuration becomes particularly useful when paired with an NVIDIA graphics card.
G-SYNC Compatible VRR can synchronize the monitor’s refresh behavior with changing GPU frame rates, helping reduce visible tearing when performance moves between different FPS levels.
For example, an RTX 4060 system may move between 165 FPS, 140 FPS, 120 FPS, and lower depending on the game and graphics settings. VRR helps maintain a smoother experience instead of forcing the display to operate at a single fixed refresh rate.
This makes the Acer Predator XB273U GS a sensible desktop companion for an RTX 4060 gaming laptop.
At 1440p, however, I would generally recommend High or Very High settings rather than automatically pushing every option to Ultra. DLSS can also be useful in demanding games, especially when ray tracing is enabled.
A Surprisingly Good Office Monitor
The Predator branding makes the Acer Predator XB273U GS look like a gaming-only product, but its 27-inch QHD format is also excellent for productivity.
The extra desktop space is useful for:
- Web browsing
- Excel
- Word
- Programming
- Photo editing
- Video editing
- Multitasking
The adjustable stand is another major advantage. Height adjustment, tilt, swivel, and Pivot support make it easy to position the screen correctly for long working sessions.
The 100 × 100mm VESA mounting support also makes it suitable for monitor arms and multi-monitor setups.
Ports and Connectivity
The monitor provides HDMI, DisplayPort, USB connectivity, and audio support. The USB hub is particularly useful for keeping a desktop setup organized.
A typical configuration could connect the computer to the monitor through DisplayPort, while a keyboard or mouse is connected to the monitor’s USB hub.
For modern PCs, this is a convenient arrangement. However, buyers looking specifically for the latest gaming-console connectivity should remember that this is an older generation of gaming monitor, so it should not be evaluated as a modern HDMI 2.1 display.
Long-Term Hardware Considerations
A gaming monitor can remain useful for many years, especially when its basic specifications are well balanced. The same principle applies to other Acer hardware in a workstation.
If an older compatible Acer device has degraded battery performance, replacing its battery can sometimes be more economical than replacing the entire device. A suitable Acer battery is therefore worth considering when maintaining compatible Acer equipment.
For a complete desktop setup, the Acer Predator XB273U GS provides the display side of the experience, while dependable power and battery components help keep the rest of the hardware usable over time.

Final Verdict
The Acer Predator XB273U GS remains a very sensible monitor if you want a balanced 27-inch QHD gaming display rather than an HDR-focused flagship.
Its formula is simple and effective: 1440p + 165Hz + IPS + VRR.
For an RTX 4060 gaming laptop, it can be an especially good match, providing a larger QHD desktop display without demanding the extreme GPU performance required by a 4K high-refresh monitor.
In 2026, however, its value depends heavily on price. Newer 1440p 240Hz and 360Hz monitors offer higher refresh rates, while OLED and Mini LED models provide substantially better HDR and contrast.
Therefore, the Acer Predator XB273U GS makes the most sense when available at an attractive price. If you prioritize smooth SDR gaming, sharp QHD image quality, comfortable office use, and an excellent ergonomic stand, it remains a well-rounded option.
And if you are maintaining compatible Acer hardware alongside your monitor setup, don’t overlook the importance of a reliable Acer battery. A good display can improve the user experience, while dependable replacement power hardware can extend the practical life of the equipment around it.
