The Acer Predator XB271HU bmiprz is reduced gaming monitor that combines a 144Hz refresh rate (overclockable to 165Hz) and a 1440p IPS panel with NVIDIA G-SYNC technology for an ideal gaming experience.
Additionally, the monitor offers intensive connectivity and ergonomic options, together with a good amount of gaming features, including NVIDIA’s ULMB motion blur reduction technology.
Predicated on AU Optronics’ AHVA (IPS) panel technology, the Acer XB271HU offers a 350-nit peak brightness, a 1,000:1 static contrast ratio, a 4ms response time speed, and 10-bit dithered color support with 100% sRGB color gamut covered.
Alas, the monitor isn’t factory-calibrated, so to find the best Acer Predator XB271HU calibration settings, you will need to fiddle with the colour adjustments yourself. Advanced 6-axis and RGB color settings can be purchased in the OSD (On-Screen Display) menu.
Many find 27″ screen size and 1440p resolution to be the perfect blend for gaming. The monitor isn’t too large nor too small, as the resolution provides just an ideal pixel density.
With 108.79 pixels per inch, you get maximum details and screen property without the UI scaling required.
Understand that the bandwidth necessary to run 1440p at 144Hz is nearly double than it’s for 1080p at 144Hz. So, you will require at least the GTX 1070 for low/minimum settings at 1440p/144Hz, according to the game.
The main complaint you might see about the Acer Predator XB271HU 27″ monitor is its IPS glow and backlight bleeding. Both of these similar but different monitor defects show as excessive light leaking around the corners or edges of the screen.
We didn’t see any prominent backlight bleeding nor any dead pixels on our unit. IPS glow, however, is expected from IPS panels.
In the event that you max out the brightness on your own screen and dim all of the lights in your room, the glow that appears on the screen is meant to happen, and you ought to either lower the screen brightness or let some light in your room.
Shifting, the Acer Predator XB271HU input lag performance is top-notch with significantly less than 5ms of delay. The response time can be impressively fast since it effectively removes virtually all ghosting and motion blur in fast-paced games.
Now, the response time isn’t as fast as that of TN panel displays with 1ms, nor may be the contrast as high as it’s on VA panel monitors; but these panels have their own drawbacks.
So, you won’t have as quick pixel transition as TN gaming monitors, nonetheless it could be more than fast enough, even without the ULMB. Moreover, black colors won’t be as black as on VA displays, but again, you won’t get the horrible motion blur you can get on VA monitors.
NVIDIA G-SYNC & ULMB
Built with NVIDIA’s G-SYNC technology, the Acer Predator XB271HU monitor permits a variable refresh rate when linked to a compatible GeForce GTX card, 650 Ti or newer.
This allows the display to improve its refresh rate dynamically and in synchronization with the GPU, that will eradicate screen tearing and stuttering once and for all.
Moreover, it won’t introduce as much input lag as VSync does; actually, the Acer Predator input lag is merely 1ms higher with G-SYNC enabled.
Alternatively, you need to use ULMB (Ultra Low Motion Blur), which via backlight strobing completely eliminates motion blur and ghosting of moving objects in video gaming.
ULMB can’t be active as well as G-SYNC as it could only just work at fixed refresh rates of 85Hz, 100Hz, or 120Hz.
When ULMB is enabled, the screen becomes somewhat dimmer without the capability to increase its brightness, and input lag gets increased somewhat to ~10ms, which continues to be imperceptible.
You need to use the Acer XB271HU with an AMD card aswell, but you won’t manage to reap the benefits of variable refresh rate nor ULMB.
When you have an AMD card, get yourself a 27″ 1440p 144Hz IPS monitor with FreeSync instead, which means you don’t pay reduced for G-SYNC for no purpose.
The XB271HU, and also the remaining Acer Predator XB1 series monitors, offer additional gaming features, including Dark Boost, used to improve the gamma curvature and increase visibility in dark elements of video games.
Next, you can set a custom Aim Point on-screen for better precision in FPS games and track your framerates/refresh rates with the Refresh Rate Num feature. Additionally, there are three customizable picture profiles.
The screen is flicker-free unless ULMB is enabled, and there’s a low blue light filter that prevents eye strain and fatigue.
Finally, you will see the Overdrive settings with Off, Normal, and Extreme modes. We advise using either Off or Normal as Extreme introduces pixel overshoot or inverse ghosting.
Design & Connectivity
The look won’t appeal to every person because of gamer-inspired aesthetics. It’s a tad bulky looking at it from the medial side, but at least the bezels are incredibly thin at the very top and in the bottom of the monitor, so it’s a fantastic choice for multi-monitor setups.
Ergonomic talents include -5°/20° tilt, -/+ 30° swivel, 90° pivot, or more to 150mm (5.9″) height adjustment. Additionally, there are 100 x 100mm holes for VESA mounting.
For 1440p at 165Hz and G-SYNC, you need to utilize the DisplayPort input. There’s a supplementary HDMI port, which maxes out at 2560×1440 at 60Hz. There’s also a headphones jack, a quad-USB 3.0 hub (two ports at the medial side), and 2x2W DTS built-in speakers.
Price & Similar Monitors
The Acer Predator XB271HU price amounts to around $700, which is much too expensive. A far more realistic price, worth taking into consideration, will be about $400.
ASUS offers an identical model predicated on the same panel, the ASUS PG279QZ, that can be found for less (~$600).
However, if you need an excellent 27″ 1440p 144Hz IPS gaming monitor, we recommend looking into the LG 27GL850, which isn’t only cheaper but also faster and will be offering a wider color gamut.
Although the LG 27GL850 doesn’t have a G-SYNC module, it supports FreeSync, and it’s G-SYNC compatible.
The Acer XB271HU was one of the better gaming monitors available back the day. Nowadays, you will discover equally good as well as better alternatives for less overall, including the LG 27GL850.
