Acer XB271HU and XB271HUT 165Hz WQHD AHVA models
Some users may be a little confused as to why we are bringing ‘news’ of the Acer XB271HU several months after its release. As it happens, we never published a news piece on this as we were expecting to have reviewed it by now. Unfortunately, a review sample of this never materialised despite repeated requests to Acer, so here we are. This also allows us to bring you some information on the XB271HUT, which is first being shown off at IFA 2016 in Berlin. This model is similar to the ‘HU’, with the notable addition of a Tobii eye-tracking sensor suite. This allows the user to interact with games and other applications that support this technology (such as Deus Ex: Mankind Divided) by using eye movement. This sensor suite is located on the underside of the matte black plastic bottom bezel as per the image below (the ‘HU’ model lacks this addition but is aesthetically identical otherwise). Note that the bezels of both models are ‘dual-stage’ with a thin hard outer component and slender panel border that blends in seamlessly when the monitor is switched off. The OSD (On Screen Display) controls are found in the form of pressable buttons towards the right of the bottom bezel.
An AU Optronics AHVA (IPS-type) panel is used, which offers a 27” screen size, 2560 x 1440 (WQHD) resolution and support for a 165Hz refresh rate (30 – 165Hz variable, with Nvidia G-SYNC). This is accompanied by support for ULMB (Ultra Low Motion Blur) as an alternative to G-SYNC – both technologies require a compatible Nvidia GPU and only one technology can be activated at once. 8-bit colour is supported (no dithering), with a flicker-free WLED backlight being used. This uses enhanced phosphors to provide comprehensive coverage of the sRGB colour space with a little over-extension for an extra touch of vibrancy. A 4ms grey to grey response time is specified; that may seem somewhat slower than TN panel alternatives such as the Dell S2716DG (and it is) where 1ms is specified, but this is one of the most responsive AHVA (IPS-type) panels out there. And you should always look beyond specified response times as they’re often misleading.
The rear of the monitors use textured matte black plastic, with a horizontal pattern for the edges and a plain texture for the central region and stand neck. The included stand is fully adjustable (tilt, height, swivel and pivot) and connects via 100 x 100mm VESA. It can be removed to make way for an alternative stand or mount. The ports of the ‘HU model’ include; HDMI 1.4, DP 1.2 (supports Nvidia G-SYNC), 4 USB 3.0 ports, a 3.5mm audio input and a 3.5mm headphone jack. The ‘HUT’ model appears from the early press shots to include DVI-D and VGA. At any rate, the full capabilities of the monitor (including 2560 x 1440 @ 165Hz and G-SYNC capability) require DisplayPort 1.2 to be used. 2 x 2W speakers also feature, for basic sound output.
Further information on the ‘HU’ can be found on this product page. Full information on the ‘HUT’ is forthcoming, with some basic information on this press release. The ‘HU’ model is now available for around $750 whilst the ‘HUT’ model is expected from December at a slightly higher price initially. We will request a review sample of the ‘HUT’ model as we’re keen to both try the Tobii eye-tracking and also the monitor itself. It may be that some basic tweaks have been made beyond this to the newer ‘HUT’ model. Most user feedback on the ‘HU’ has been quite mixed, with users citing poor quality control and a fair likelihood of moderate backlight bleed plus some other panel defects. Most seem quite happy ‘once they get a good unit’, however.
