Best Gaming Monitor Under 400 USD



The Nixeus EDG27S v2 is the upgraded model of the popular Nixeus EDG27S (Nixues NX-EDG27S, Nixeus NX-EDG27).

It’s based on the same panel, but features thinner bezels and introduces FreeSync support over HDMI (in addition to DisplayPort) as well as G-SYNC compatibility.

What makes this gaming monitor (both the old and the new versions) so well-received is, first and foremost, its affordable price for a 27″ 1440p 144Hz display with an IPS panel.

Additionally, it has a wide 30-144Hz FreeSync range out of the box and it’s actually the only FreeSync model that supports adaptive overdrive.

Image Quality

Based on an AHVA (IPS) panel by AU Optronics, the Nixeus NX-EDG27S v2 features true 8-bit color depth, 178-degree wide viewing angles, a 300-nit peak brightness, and a 1,000:1 static contrast ratio.

Out of the box, the picture is decent, but calibrating the display is desirable as it can notably improve the image quality.

There is some moderate IPS glow which is expected from this panel technology. By reducing the maximum brightness a bit and introducing some ambient lighting, the IPS glow is barely noticeable while using the monitor, even in dim-lit environments.

1440p provides the perfect pixel-per-inch ratio of 108 PPI on a 27″ screen of the Nixeus EDG27S v2 monitor which translates to sharp and crisp details as well as plenty of screen space without any scaling necessary.

In general, the image quality is excellent considering the monitor’s price and it can be further improved via calibration. There were no dead/stuck pixels on our unit nor excessive backlight bleeding.

The backlight is flicker-free and there’s a low-blue light filter, so you can game for hours without straining your eyes.

Moving on, the performance of the Nixeus EDG27S v2 display is excellent as well. The input lag amounts to ~6ms at 144Hz which makes for imperceptible delay.

The response time speed of 4ms (GtG) efficiently eliminates most of trailing and motion blur of fast-moving objects in fast-paced video games.

There are four response time overdrive options (off, low, medium, and high) to be used according to your liking and preference.

The Nixeus EDG27S v2 is one of the rare FreeSync models that comes with a wide 30-144Hz variable refresh rate (VRR) range out of the box. It also supports AMD Low Framerate Compensation (LFC).

VRR eliminates all screen tearing and stuttering with minimal (~1ms) input lag penalty as long as your FPS (Frames Per Second) rate is within the dynamic range of 30-144FPS. Below that, LFC kicks in and makes the display’s refresh rate double/triple the frame rate (at 20FPS, you get 40Hz, etc) to ensure smoother performance.

Setting the response time overdrive to ‘Off’ will actually make the monitor change the overdrive preset to Low, Medium, or High according to the frame rate when FreeSync is enabled. This way, you will get no pixel overshoot at lower frame rates and no ghosting at high frame rates.

This adaptive overdrive isn’t quite as effective as G-SYNC’s variable overdrive, but it’s certainly useful, especially after considering that many FreeSync monitors can’t even run FreeSync and High overdrive simultaneously, let alone change it on the fly.

If you have an NVIDIA GTX 10-series, GTX 16-series, RTX 20-series, or newer, you can also use FreeSync without any issues as the display is G-SYNC compatible, even though it’s not certified by NVIDIA.


The OSD (On-Screen Display) menu is somewhat outdated and navigating through it via the clunky monitor’s hotkeys isn’t particularly user-friendly.

There aren’t any modern gaming features such as fancy RGB lighting, pre-calibrated gaming picture presets, customizable crosshairs, and similar tools, but you will find all the standard adjustments such as contrast, brightness, color temperature, gamma, audio volume, and input source selection.

We don’t really hold any of this against the Nixeus EDG27S v2 IPS gaming monitor considering that you won’t spend much time in the OSD menu anyway, at least after calibrating the display.

Besides, the common ‘gaming’ features are usually just gimmicks. Many would consider having fixed crosshairs as cheating while pre-calibrated presets such as FPS, RTS, Racing, etc usually just make the picture worse, and features such as Black Stabilizer, Shadow Control, etc just alter the gamma curvature which you can do manually in the video game or monitor’s settings.

We’d rather take adaptive overdrive and wide VRR range out of the box than the above-mentioned features.

Design & Connectivity

Nixeus Nx Edg27s V2 Review 2019

The design is nothing special. The bezels are visibly thinner than on the previous version, but still not what we would call ‘ultra-thin’. The stand is tilt-only, but luckily you can mount the screen on a third-party stand via the 100x100mm VESA mount pattern.

Just like the previous generation, the Nixeus EDG27S v2 will also be available with an ergonomic stand as the Nixeus EDG27 v2 (without the ‘S’ suffix).

Connectivity options have also improved. There are now two of each: DisplayPort 1.2 and HDMI 2.0 while FreeSync works over all ports (G-SYNC works over DisplayPort only) with a 30-144Hz range. There’s also a headphones jack and two basic built-in speakers.

Price & Similar Monitors

The Nixeus EDG27S v2 price amounts to around $400 which is a very good deal.

For extra $100-$200, you can get the Acer Nitro XV272U/VG271UP or the Aorus AD27QD which are 27″ 1440p 144Hz IPS gaming monitors that support HDR, 10-bit color, and backlight strobing.

Since these monitors have only entry-level HDR support (DisplayHDR 400) and most games don’t support HDR nor 10-bit color depth, the Nixeus EDG27S v2 is an excellent cheaper alternative.


Overall, the Nixeus EDG27S v2 is the best gaming monitor you can get under $400. It offers the perfect balance between a vibrant image quality and a smooth performance. What’s more, it has one of the best FreeSync implementations which makes us let the lack of gimmicky features and fancy OSD menu slide.
