The whole purpose of 4K displays is to offer immersive gaming experiences. Whether you own a 4K-ready console or a powerful gaming PC, here are the top gaming best 40 inch 4k monitors that you can opt for.

1: Best 40 Inch 4K Gaming Monitor – ASUS ROG Swift PG27UQ

ASUS is among the first brands to offer 4K, HDR and high refresh rates in a single package. The quantum dot display makes it stand out from the rest of the 4K monitors in the market. Asus has managed to balance out the colors quite well and brightly lit areas in games are where the monitor really shines. 

While other monitors suffer from backlight bleeding, the Dot IPS display manages to show all of the finer details with zero backlight bleed. IPS displays are known for their great viewing angles without affecting the viewing angles but it comes at the expense of low backlight levels. The ROG Swift resolves that issue with the Quantum Dot technology making it quite easy for gamers to comfortably see everything on-screen even from off angles. 

The ROG Swift PG27UQ comes locked at 60Hz refresh rate and you need to bump up the refresh rate from the OSD for best results. In terms of connectivity, there is a Display Port 1.4, an HDMI 2.0 port and a generous USB array with 4 ports. You can use the locking mechanism to set up the monitor in portrait mode. 

As long as you pair the monitor with the appropriate hardware, you will be more than satisfied with the ROG Swift PG27UQ. This is the best 4k gaming monitor that can cater to your gaming needs for years to come and we cannot recommend it enough.

2: Best 4K HDR Gaming Monitor: Acer Predator X27

The Acer Predator X27 is among the only monitors that support 4K, blazing-fast refresh rates and HDR. With a wide color gamut, the Predator X27 is one of the most color-accurate monitors we have ever tested. It is capable of handling fast-paced visuals with zero screen tearing. Gaming on the Predator X27 feels very satisfying thanks to the ultra-realistic colors and smooth frame transitions. If you have content that supports HDR, you will see what the X27 is truly capable of. 

Navigating across all the controls is enabled through the use of four buttons and a clickable joystick that you will find on the back of the monitor. While it might not be the most intuitive OSD we have ever seen, the amount of customization it offers is commendable. Aesthetically, Acer separates the X27 from other standard monitors with dynamic lighting and futuristic design elements. 

Acer did enable overclocking on the X27 but recommended against it unless you have a very GPU like the new RTX series from Nvidia or the last generation Pascal cards. With the monitor coming tuned with 99% AdobeRGB coverage as well as 100% sRGB coverage making it great for professional use as well. 

In terms of performance, the X27 performs only as good as your gaming rig. If you do not have a top-end gaming PC, a PS4 Pro or an Xbox One X, chances are you will not be able to make use of the X27’s full potential. Ray Tracing is something Nvidia has been stressing on a lot lately, and if you own an RTX or RTX Super GPU, we recommend turning on ray tracing for some impressive visuals on the panel. 

The X27 is great for anyone looking for top-notch specs, and it doesn’t cost an awful lot of money if you consider the features that it offers. It is a well-rounded product that delivers on all fronts and if you need a solid HDR 10 monitor, look no further than the Acer Predator X27.

3: Best G-Sync 4K Gaming Monitor – Acer Nitro XV3

The gaming peripherals industry is at a spot where 4K monitors are capable of pushing out more frames than what top-end gaming PCs can push out. Even with an RTX Super GPU and a premium chipset, you will not be able to push more than 60 frames per second consistently. That is where Acer steps in with its Nitro XV3 equipped with Nvidia’s G-Sync technology. 

The XV3’s G-Sync capabilities ensure that you experience no screen tearing even if your gaming rig is displaying 4K content at well below 144 frames per second. Everything continues to look buttery smooth, and it adds to the immersive experience that every gamer deserves. 

The panel itself comes with removable glare blockers which are must-have if you play in brightly lit rooms or have a multi-display setup. Under the hood, the XV3 packs HDR technology with a 90% DCI-P3 color spectrum and over 85% of Adobe sRGB’s color spectrum. While it might not be the perfect monitor for video editing or professional use, for gaming, it is a beast of a monitor. The colors are slightly exaggerated intentionally to make things look more vibrant and immersive. But if you want to tone down the saturation and contrast you can do so using the physical buttons tucked away in the panel. 

Something you need to note is that if you want to leave Nvidia G-Sync enabled you to need to tone down the refresh rate to 120Hz. G-Sync does not work at 144Hz or higher at 4K on the monitor. We recommend leaving G-Sync on as turning down the refresh rate by such a small margin will not affect your gaming experience.  

Even though the Nitro lineup of gaming products from Acer is meant to be a step down from the Predator series, Acer was generous with the aesthetic details. With a curved matte-black casing and brushed plastic molding, the monitor feels premium. Overall, the XV3 sits at the perfect price point for those who want access to all of the best features from the world of 4K gaming monitors. You get access to high refresh rates, amazing color accuracy, Nvidia G-Sync, and AMD Freesync in one package and it is nearly impossible to beat that kind of value. 

4: Best Freesync 4K Gaming Monitor – Asus MG28UQ

For those who do not own an Nvidia GPU to support G-Sync and want to take advantage of AMD’s Freesync technology instead, the Asus MG28UQ is the way to go. G-Sync monitors typically have a hefty price bump on them, but that is not the case with AMD’s Freesync technology. 

The 40” monitor from ASUS borrows a ton of exterior design features from the rest of the MG series, and it comes with the iconic traditional graphite matte black finish seen in other products in the lineup. The ultra-thin bezels ensure you get maximum immersion without the black bars getting in the way of your gaming. Multi-display support on the MG28UQ is great thanks to the great curvature and minimalistic frame on the panel. The power supply unit of the monitor is built right into the back chassis, making cable management a breeze as you do not have to clutter your desk with a power brick. 

Unlike Nvidia’s G-Sync, there are no I/O port limitations on this monitor, and you get plenty of options to choose from when it comes to connectivity. On the back, you will find one DisplayPort 1.2, an HDMI 2.0 port, two HDMI 1.4 ports, and three USB ports. If you do not want to use the built-in speakers, you can also make use of the 3.5mm port for audio. 

The Asus MG28UQ blurs the line between luxury and mid-range monitors with just about everything going right for it. Sure, you miss out on Nvidia G-Sync, but if you are running the latest AMD Navi architecture cards, you definitely want to go to the Freesync route instead. It’s the best Freesync monitor out there with a landslide, and we recommend picking it up if you want an immersive 4K gaming experience.

5: Best Budget 4K 40 Inch Gaming Monitor – Dell S2817Q

Dell S2817Q is the best budget 4k gaming monitor and if you have been holding back from buying a 4K monitor, now is the right time to grab one without breaking the bank. You get a 40” screen that boasts of sharp picture quality with a ton of adjustments available from the physical controls. The S2817Q goes far beyond just gaming. The superb color accuracy makes it a great product for designers and content creators.

While everything sounds great so far, Dell must have cut some corners, right? Unlike more expensive monitors, the S2817Q comes with a TN panel while the monitor might not have the best viewing angles, it should not affect gamers anyway as performance is what matters the most. 

HDMI 2.0 connectivity is available for plugging in your console, but you want to connect the monitor via the supplied DisplayPort 1.2 if you want high refresh rates. The physical buttons are located at the back of the panel, and you can make a variety of adjustments to your color gamut, color temperature, contrast, brightness and more. There is a power-saving mode as well if you want to reduce your power consumption when gaming for long hours. 

The S2817 Qis a robust gaming monitor with very few drawbacks with the panel size. 4K on a 40” panel might be a little overkill, but we aren’t going to complain as it increases the PPI and offers a more immersive experience when gaming closes up. The glare can also get in the way, but it is not an issue that cannot be solved with a simple anti-glare filter that you can grab for a couple of bucks.

Dell skipped a few features here and there, but ultimately the product is an amazing entry-level gaming monitor that delivers on all fronts. If you do not have the budget for an overly expensive Nvidia Big Gaming Monitor and are content with a 40” display for your 4K gaming needs, you cannot go wrong with Dell’s offering.
