Acer Predator X27 Front

From the minute you lay eyes on the Acer Predator X27, you know this is a serious gaming monitor aimed at people who are willing to shell out for the best money can buy.

The X27 is one of the brand’s flagship monitors aimed at serious and competitive gamers. If you are looking for a monitor which is both a top-performer for competitive gaming, and comes with the aggressive looks to back that title, this would be an excellent choice.

The monitor includes many high-end features such as Full HDR support, a very-bright 1000nits backlight with local dimming support, and G-Sync HDR for a stunning viewing experience.

Joining the growing list of Acer Predator X27 fans, we were thoroughly blown away by the features and performance of this top-shelf monitor.

Image Quality

The Acer Predator X27 sports an IPS panel that supplies 10bit Color with Quantum Dot Technology to make your games into the eye candy you expect from such a premium monitor.

The monitor is capable of 99% Adobe RGB Color Gamut and DCI-P3 Color Space, indicating that the monitor can offer excellent color with higher brightness.

Enabling sRGB mode will lower it to 97% coverage, but most other features will not be affected by the use of this mode.

The display includes a 600 nits FALD backlight with local dimming support, and a maximum pulse of up to 1000 nits for HDR content. This qualifies the panel for the premium HDR1000 certification.

Gaming Performance

The Acer Predator X27 comes with a 27-inch IPS panel with AU Optronics with a 4K/UHD 3840 x 2160 resolution, a maximum 144Hz refresh frequency, and a 4ms GTG response time (at 4k resolution).

The display includes a 600 nits FALD (Full Array Local Dimming) backlight with local dimming support, and a maximum pulse of up to 1000 nits for HDR content.

While HDR1000 is something found on many TV’s, it’s quite uncommon to find on a monitor – especially one with 4K resolution.

Keep in mind, you won’t be able to utilize the 144Hz refresh rate option, with the default configuration. If you want to game at that refresh rate, especially in 4K resolution, you’ll need to overclock the monitor through the settings menu.

For those who are looking for the best possible image in a bright room, HDR1000 certification on a gaming monitor is the current best money can buy.

4K at 144Hz is also the current best for any gaming monitor we have seen so far – but keep in mind you will need a very powerful graphics card to run games smoothly at this speed.

Standout Features / Design

At first glance, one of the more notable features of the Predator X27 are its side shields/flaps, which are designed to reduce glare on the monitor and focus your vision on the screen for maximum gaming attention.

We here at InputLag are fans of the flaps, because they really do help with concentration especially when playing next to other people (like at competitions).

For many users who game at home, many may feel these add-ons are useless, but for some, they have a certain value. They are easily detachable in case you would like to use both configurations.

Playing in a well-lit room can reduce the benefits of FALD (Full Array Local Dimming) backlighting, so having a level of glare protection is a must for some.

View / Ports

Ports: One DisplayPort 1.4, one HDMI 2.0, two USB 3.0, 3.5mm audio jack.


In short, the Acer Predator X27 is the sort of monitor you would expect when searching for the best that money can buy.

It’s no coincidence that you will see this monitor being used by many of the top players in the world. With a response time of only 4ms in 4K mode, it is one of the fastest 4k panels available on the market today.

4K resolution is notorious for increasing lag/response time since there is much more data to process with all those extra pixels, so don’t underestimate the power of this feature. We also love the minimalist design of this model, preferring it to the busy RGB-laden aesthetics of ASUS PG27UQ.

Some may be put off by the higher price tag, or lack of being a curved or UltraWide panel. Rest assured, with the specs this monitor brings to the table I feel it more than makes up for it. For those looking for a monitor that will best any other 4K gaming screen on sale so far, you can’t go wrong with selecting this one to use.
