Dell Gaming S2721HGF Review 27 Inch Curved 144Hz 1080p Gaming Monitor

Dell’s S2721HGF is one of the cheapest 27in displays we’ve seen for some time, and that makes it a tempting option for anyone who wants a sizeable gaming display without spending silly amounts of cash.

Its kitted out with a 1080p VA panel that’s compatible with AMD FreeSync Premium and Nvidia G-Sync at 144Hz, and it has a 4ms response time. On paper, that means its good enough for tackling mainstream single-player games and esports titles without putting a huge amount of stress on your GPU to hit a sky-high refresh rate.

The Dell has a 1500R curve, too, which improves immersion. That said, twitchy esports players will benefit from a non-VA 240Hz display with a 1ms response time, and a 2,560 x 1,440 resolution would make games look crisper – the 1080p resolution across this 27in display results in a low pixel density and it doesn’t look particularly sharp.

On the outside, the Dell looks decent, and it has slim bezels, so affordable multi-monitor gaming is possible. It’s easy to assemble, the stand has a cable-routing hole and the on-screen display menu system is well organized, fast and managed by a snappy joystick control.

At this price, though, compromise is inevitable. Build quality is mediocre: the rear moves too much and the screen wobbles. The Dell has 100mm of height adjustment alongside tilt movement and 100mm VESA support, but there’s no swiveling, and the movement is stiff. This display has no USB ports or speakers either.

Dell’s display squares up against the AOC 27C2U, which is our favorite affordable 1080p 27in panel. That screen has more adjustment, and it includes speakers and USB ports. The AOC isn’t curved, but it does have a 1ms response time.

The Dell delivered a stunning contrast ratio of 3,138:1, which is far higher than the AOC’s IPS panel. The black point of 0.08cd/m2 is stellar, and those results create a bold, punchy gaming display with impressive depth in darker areas. The active sync features provided tear and stutter-free gameplay, although there’s still a little blurring in the fastest situations at 144Hz. There’s barely any inverse ghosting unless you use the toughest overdrive mode, but those options don’t create a significant improvement either.

Meanwhile, the Dell’s delta E of 2.16 is reasonable rather than outstanding, and its color temperature of 6,359K is good. Its gamma average of 2.37 is wayward, though, and this display rendered 90.8 per cent of the sRGB gamut at 98.4 per cent volume, so it can’t display every shade properly. Everyday gaming won’t be significantly hindered by these middling figures, but the IPS-based AOC is better.


The Dell S2721HGF has huge contrast and a deep black point, and those attributes mean you get a punchy and vibrant experience. The colors are good enough to handle mainstream gameplay, and it has decent syncing options too. The rival AOC display doesn’t match the Dell in contrast, but it still hits 1,447:1 there, and the AOC has superior colors and a more responsive IPS panel. The Dell also has mediocre adjustability and few extra features, and the AOC remains better in those areas too.

The Dell can handle mainstream gaming, and its contrast means it has loads of punch and depth, but there are also disappointing compromises in several other areas. With superior colors and more features, the AOC 27G2U remains our budget 27in display of choice.
