This is a monitor that wants to wow with its unusual design, featuring a nearly bezel-less display and a fixed offset stand that‘s offset of central to hold the panel in the air. If you’re after a cheaper 4K display, AOC’s 28in U2868PQU monitor is just £330
Acer S277HK review: Build and Design
Here is a desktop monitor which sets itself apart from the all-black school of display, instead using glossy white plastics across the back panel and a natural aluminium finish support stand. There is plastic trim running up the centre of the back and around the display’s edge, sprayed in silver to match the stand finish. The brand name ‘acer’ is emblazoned across the back in lower case on an otherwise neatly finished part of the monitor that’s too often overlooked by monitor manufacturers. Read: ViewSonic VP2780-4K UHD monitor review. From the front there’s little to see apart from the 3840 x 2160 pixel IPS panel and a chin piece that runs along the bottom; a veneer of aluminium trim with a brushed grain effect. Acer markets the monitor as frameless although it’s not a true ‘infinity’ display that goes right to the edge – the visible display is framed by a black and silver border around 8 mm wide along the top and side. Meanwhile the bottom strip measures 25 mm thick. While the stand is minimal and stylish, we found it to be simply too low to be used comfortably. Placed on a desk it will need lifting by a few books’ height to bring it to a safe working height that doesn’t cause neck strain from poor posture. Normally we’d suggest trying a third-party stand attached to the monitor’s rear VESA mount, but this monitor doesn’t have one. The panel’s provenance is unknown, but appears to be a gloss-finished type that has been treated to a stick-on anti-glare film. This does a great job of reducing annoying reflections although it also adds a layer of sparkly grain to the image, making it more soft-focused than panels with a factory-applied hard coat anti-glare finish. Connections are made to the panel above the stand mount point at the rear, with cables docking perpendicular to the panel. There’s a choice of regular and Mini DisplayPort (both to v1.2 standard), DVI and HDMI. Most usefully, the latter is the latest v2.0 standard so will allow native UHD resolution at full 60 Hz refresh rate. That could prove invaluable in future-proofing, for when HDMI 2.0 finally becomes commonplace on PCs.
Acer S277HK review: Control
The S277HK relies on four hidden buttons under the screen bezel for adjustment. These buttons are sunken into the frame and only just pressable after a concerted effort since they’re so recessed. The OSD that appears is fixed in the bottom right corner, and requires you to move your finger between different hidden buttons that lie under changing on-screen graphics. It’s not the worst OSD setup menu we’ve seen but did prove annoying to navigate.
Acer S277HK review: Performance
The colour gamut of the Acer’s IPS panel was wide enough to fully encompass the sRGB colour space, and with a reported 80 percent cover of the Adobe RGB space it also measured by a fractional margin the widest colour spread in this group. Contrast ratio was good when compared to budget displays, if a little low for an IPS technology screen and actually the poorest on test, showing a 530:1 ratio. Most high-quality IPS panels will be closer to 600: or 700:1. Colour accuracy was very good, with an average Delta E figure of just 1.08. Brightness variation was average, the top third of the screen darker by around 15 percent, increasing to 25 percent darker than the bottom at a nominal ‘25’ brightness setting. In use this is still not a major issue. Sound quality from the built-in stereo speakers was passable for system alerts but tinny and annoying for music. Don’t be fooled by the DTS brand badge in the marketing – this is no hallmark of audio quality any more, and in this example switching the DTS function on served no audible purpose whatsoever.
Acer S277HK review: Power consumption
With a peak draw of 53W at full brightness (280 cd/m^2), the Acer is a little higher than others of its size and resolution. Down at a more usable 120 cd/m^2 it drew 29W of power.
