Computer hard-drives are growing more powerful each year. And with better-performing CPUs and GPUs, as advancements in graphics API (Vulkan and DirectX12), games are no longer limited to 1080p to provide an optimal experience. In fact, this year’s lineup of CPUs and GPUs will have no problem producing MOBAs like Dota 2 and more recent open-world games, such as Grand Theft Auto V, 144 fps on 1440p (QHD).
Note that DOTA 2 is very CPU-bound while GTA V will utilize both the processor and graphics card.
With that said, there’s no question that 1440p works well with 27-inch monitors since it can make full use of all those pixels. It’s just the right balance of resolution and screen size for gaming. However, if you want to take gaming seriously, there’s more to monitors than just the pixel density. Refresh rate, type of panel—which greatly affects the response time, input lag and adaptive sync technologies also need to be considered. There’s also the viewing angle, which comes in handy if you’re planning a multi-monitor setup.
Do bear in mind that while adaptive sync technologies (Nvidia’s G-Sync and AMD’s Free-Sync) will help with lowering the input lag and preventing stuttering and screen tearing, they also come at a premium. Needless to say, this list of the 5 best gaming monitors at 27 Inches will have some really pricey ones.

Asus ROG Swift PG279Q and PG278Q
Price: $792 and $670, respectively
This near $800 offering from Asus has been reviewed by multiple critics and many of them hail it as the best 27-inch 1440p gaming monitor out in the market today, which is not unfounded.
The PG279Q is aesthetically pleasing to look at and its thin bezels don’t hurt either. It uses an IPS panel that allows for a 178-degree viewing angle. Surprisingly, Asus managed to bring the response time down to 5 ms and input lag to 3 ms.
However, PG279Q’s real highlight is the fact that its refresh rate can go up to 165 Hz. And yes, it incorporates Nvidia’s G-Sync display technology. As for the I/O, Asus fitted it with a display port, an HDMI port, 4 USB ports and a headphone jack.
A more pocket-friendly option is the Asus PG278Q, which uses a TN panel that makes the 1ms response time possible. It also has Nvidia G-Sync.
However, the PG278Q has fewer USB ports and is limited to 144 Hz, which are not really deal-breakers.
The S2716DG uses a TN panel, which has its strengths and weaknesses. While IPS provides better the viewing angles and color accuracy, TN offers better response time, which is evident with the S2716DG’s 3 ms. This one is the most affordable gaming monitor in this list.
The S716DG has a 144 Hz refresh rate, which is expected of a premium 27-inch 1440p. And as you may have guessed, the price got pushed because it also features Nvidia’s G-Sync. However, among monitors in this list, it has the worst contrast ratio at 1000:1.
Just like Asus’s pricier offering, this Dell monitor has 4 USB ports, 1 display port, 1 HDMI port and a headphone jack.
BenQ ZOWIE XL2730
The XL2730 runs at 144 Hz and uses a TN panel, which doesn’t make the 1ms response time surprising. However, it doesn’t have G-Sync, which is questionable given the price it’s listed for. It is the most affordable gaming monitor in this list.
Nonetheless, it should be noted that most owners report no difference between monitors with adaptive-sync technologies and the XL2730.
For I/O, BenQ packed a DVI-DL, D-Sub, 2 HDMI ports, DP1.2, along with a headphone and mic jack.
Acer Predator XB271HU
Just like the Asus ROG Swift PG279Q, the Acer XB271HU can run at 165 Hz. Natively, it’s a t144Hz 27-inch 1440p monitor. Same with the PG279Q, it puts to use an IPS panel, but manages a 3ms response.
The XB271HU ties with the PG279Q in terms of input lag (3 ms). It also features G-sync. Even the I/O is similar to that of the said Asus monitor – 4 USB ports, 1 display port, 1 HDMI port. However, it has a lower contrast ratio at 1030:1.
