1.Alienware 25 AW2521HF

Pros & Cons

The Alienware 25, in its so-called Lunar Light color scheme we tested (model AW2521HFL), is white and black, just like Alienware’s recent Aurora desktops (as well as the Sony PlayStation 5). The 25-inch screen is flat and has barely any bezel, with only a thin black band running along three edges. A narrow black strip on the bottom edge features the Alienware logo.

On the back, most of the monitor is white plastic, with black inserts where the ports can be found and on the joint where the stand connects to the screen. It’s a striking look, and a nice departure from the usually boxy, black look of most monitors, even many elite gaming ones. (That said, Alienware also offers a blacked-out version dubbed “Dark Side of the Moon,” model AW2521HF)

2.LG 27GL83A-B

Pros & Cons

The LG 27GL83A-B is a very good monitor with a 27 inch, 1440p IPS screen. It delivers a great gaming experience with extremely low input lag, an outstanding response time, and a few great gaming features. It supports AMD’s FreeSync variable refresh rate technology (VRR), but it’s also certified by NVIDIA to support VRR from recent NVIDIA graphics cards.

It has wide viewing angles, good reflection handling, and very good peak brightness, so glare shouldn’t be an issue. As a more budget-oriented model, it has a pretty basic stand, with limited ergonomics and no RGB lighting. Although it supports HDR, this doesn’t really add much, as it can’t get bright enough to deliver a true HDR experience and has a low contrast ratio.

3.LG Premium Ultragear 27”

Pros & Cons

LG’s UltraGear 27GN950 is a 4K gaming monitor that almost does it all. The company has pulled out all the stops, aiming to deliver a premium screen for gaming, content creation, and media consumption, and it has pretty much succeeded. The UltraGear 27GN950 is an absolutely fantastic monitor, and save for a few minor quibbles, it provides a stellar experience through and through.

Even before you power it on, it already impresses with its spec sheet. A crisp 4K resolution and 10-bit colour. Fluid 144Hz refresh rate. NVIDIA G-Sync Compatible.

DisplayHDR 600 certification. LG’s Nano IPS panel. The entire package comes together nicely, and the monitor is one of the best I’ve had the pleasure to use.

4.Acer Nitro XV340CK

Pros & Cons

The Acer Nitro XV340CK Pbmiipphzx 34 inch is a great ultrawide gaming monitor. It delivers a great gaming experience that feels smooth and responsive thanks to its low input lag and high refresh rate. Its excellent response time makes fast-moving content look crisp, and it has an optional Black Frame Insertion feature to improve motion clarity further.

FreeSync is supported natively to help minimize screen tearing, and it’s compatible with NVIDIA’s G-SYNC. Its ultrawide format provides plenty of screen space for multitasking, and it even has a Picture-in-Picture mode that lets you display two input sources at once. Unfortunately, it doesn’t get very bright, so visibility can be an issue in well-lit rooms. Also, while it has HDR support, it can’t display a wide color gamut, resulting in a lackluster HDR experience.

5.ASUS TUF Gaming VG259QM

Pros & Cons

The ASUS TUF Gaming VG259QM is an excellent IPS monitor that delivers a smooth and responsive gaming experience. It shares many similarities with its bigger brother, the ASUS VG279QM, as it also has a 1080p resolution and a 280Hz refresh rate. It has great visibility in bright environments thanks to its impressive peak brightness, but to the contrary, it isn’t as well-suited for dark rooms due to its low contrast ratio.

It has exceptionally fast response time, a Black Frame Insertion feature, as well as native FreeSync support and G-SYNC compatibility. It supports HDR10; however, HDR content doesn’t look significantly better than in SDR because it lacks a wide color gamut and local dimming. On the upside, it has a great build quality, wide viewing angles, and outstanding ergonomics.
