Z-Edge Gaming Monitor UG27S 27" Black

The Z-Edge UG27S is a 27-inch curved gaming monitor built for speed, with a 300Hz refresh rate and 1ms response time that competitive gamers will love. It packs an impressive array of ports including Thunderbolt, but the 1080p resolution and basic stand hold it back for general use. If you find it around $200, it's a killer deal for an esports-focused display.

In our testing, the UG27S delivers exactly what its spec sheet promises: blistering motion clarity. The 300Hz refresh rate puts it in the 92nd percentile for performance among all monitors we've tracked. That means it's one of the best on the market for pure speed. In games like Valorant and CS2, the difference between 144Hz and 300Hz is immediately noticeable. Tracking fast-moving targets feels smoother, and the 1ms MPRT keeps ghosting to a minimum. FreeSync support works as expected, keeping screen tearing at bay without introducing noticeable input lag.

Color performance is solid but not spectacular, landing in the 66th percentile. The VA panel covers 16.7 million colors and looks decent after a quick calibration, but out of the box it's a bit cool. The 300-nit peak brightness is about average for this class. You can game in a well-lit room without issues, but HDR content looks flat. This isn't a monitor for photo editing or immersive single-player eye candy. It's a competitive gaming tool, and in that role, the motion handling is what matters. And it nails that.

Stacked against the LG UltraGear 27GX790A-B, the Z-Edge holds its own on speed but falls behind on image quality. The LG offers better color accuracy and a more refined OSD, but you'll typically pay more for it. The ASUS TUF Gaming VG27AQL5A steps up to 1440p, which makes text and textures noticeably sharper, though its refresh rate caps at 170Hz. If you split your time between competitive games and single-player eye candy, the ASUS is the better all-rounder.

The Dell S2725QC and BenQ MA270U are different beasts entirely, aimed at productivity with 4K panels and USB-C hubs. They're not in the same speed conversation. The Acer Nitro XV272U W2bmiiprx is a closer rival, also a 1440p high-refresh option, but again, you're trading raw Hz for resolution. If your only goal is maximum frames per second in esports titles, the Z-Edge's 300Hz panel is the clear winner here. Just know you're sacrificing sharpness to get it.

Pricing on the UG27S is all over the map depending on where you look, with a spread of over $2,800 across vendors. That's wild, and it means you absolutely need to shop around. The sweet spot seems to be around $150 to $250 from retailers like Amazon and Newegg, where it becomes a serious bargain for a 300Hz monitor. At that price, you're getting top-tier speed and connectivity that rivals monitors costing twice as much. If you see it creeping toward the $300 mark, the value proposition starts to wobble, and you should start looking at 1440p high-refresh options instead.

The Z-Edge UG27S is a 27-inch curved gaming monitor that goes all-in on speed. With a 300Hz refresh rate and a 1ms MPRT response time, it's built for competitive gamers who want every possible frame in fast-paced shooters. The 1080p resolution on a VA panel keeps things snappy, and the 1500R curve adds a bit of immersion without being too aggressive for a desk setup. If you're hunting for a high refresh rate monitor that won't completely destroy your wallet, this one lands in a pretty interesting spot.

Connectivity is a genuine strong suit here. You get two DisplayPort and two HDMI ports, which is more than most monitors in this class offer. There's even a Thunderbolt port, which is a rare find and makes it easy to dock a laptop. The ultra-slim bezels give it a clean, modern look, and the matte screen does a decent job fighting glare. At around 3.6kg, it's not exactly a featherweight, but the VESA mount compatibility means you can get it off the stand if you want a cleaner setup.

Build quality and image quality are where things get a bit more grounded. The 300-nit brightness and 8-bit color depth are fine for gaming, but don't expect HDR to blow you away despite the HDR10 badge. The stand only offers tilt adjustment, so you'll need a monitor arm if you want height or swivel. For the price, though, the sheer speed and port selection make it a compelling option for anyone prioritizing performance over pixel density.

Skip the Z-Edge UG27S if you do any kind of color-critical work like photo editing or graphic design. The VA panel and 8-bit color depth just aren't built for that. It's also a pass if you mainly play story-driven games and want rich HDR visuals, the HDR10 support here is mostly on paper. If you need a sharp display for reading text all day, the 1080p resolution on a 27-inch screen will strain your eyes. Look at a 1440p IPS monitor like the ASUS TUF Gaming VG27AQL5A instead. And if you don't play competitive shooters, you're paying for speed you'll never really use.

The Z-Edge UG27S is a specialist. It does one thing extremely well: deliver a buttery-smooth 300Hz experience for competitive gaming. If you're deep into Valorant, Apex Legends, or Rocket League and you're still on a 144Hz screen, the upgrade is going to feel transformative. The generous port selection, including Thunderbolt, is a genuine bonus that makes it easy to integrate into a multi-device setup.

But this isn't a monitor for everyone. The 1080p resolution on a 27-inch screen means text and desktop work look a bit pixelated. The stand is basic, and the HDR is more of a checkbox than a feature. If you play a mix of fast shooters and visually rich RPGs, a 1440p 165Hz monitor will serve you better. For pure esports on a budget, though, this is a fantastic pick, just make sure you're getting it at a good price.
