Acer Predator X27: the superfluous at a golden price
Gaming in 4K-HDR with up to 144 Hz: that's what the Predator X27 promises. How good is this gaming monitor from Acer? I was able to test it for a few days.
I wander through the forests of Montana. The flora and fauna are breathtaking. I feel like I'm surrounded, I can almost smell the ferns around me. I'd never seen such an explosion of colour in a game before. Far Cry 5 mesmerises me again in HDR.
The images on the screen of the Acer Predator X27 are simply stunning. No wonder, because as well as its 3840 x 2160 pixel resolution and 144 Hz refresh rate, this monitor also features HDR and NVIDIA G-Sync technologies.
Here are its main features:
- 27-inch 4k (3840 x 2160) IPS display, 16:9 aspect ratio and 144 Hz
- 1000:1 contrast ratio
- Response time (grey to grey): 4 ms
- Image refresh rate: 144 Hz
- HDR 10 and HDR 1000 display
- Colour depth: 10 bits (8 bits + FRC)
- Coverage of Adobe RGB colour space: 99%
Appearance and ergonomics
With the exception of the "Predator" logo and its stand, this screen looks nothing like a gamer's screen. This no doubt has to do with the fact that Acer also wants to attract photographers and graphic designers, not least thanks to the 99% Adobe RGB colour coverage.
The monitor can be adjusted in height by around 13 centimetres and tilted forwards or backwards. This is done very easily. Once adjusted, the monitor could almost survive an earthquake. It can also be wall-mounted. Acer also uses a blue light filter to protect users' eyes. The monitor has the following connectors:
- 1 x USB 3.0 upstream port
- 4 x USB 3.0 downstream port
- 1 x HDMI type A 2.0 port
- 1 x Display Port 1.4
- 1 x 3.5 mm jack
Acer has therefore been very generous in terms of connectors.
Settings
The OSD menu allows you to make all sorts of settings: image, colour, audio, gaming, OSD or even system settings. Each specific setting can then be assigned to three different profiles: action, racing and sports.
The OSD menu is navigated using a mini joystick located behind the screen. The grip leaves a little to be desired. Instead of confirming when I pressed, my finger slid across the joystick several times, making me validate another choice. The OSD structure seemed very clear to me, not least because there is only one sub-menu.
Image quality
To get a first impression of image quality, I decide to do the Eizo monitor test. My test device shows no pixel errors, reproduces grey levels evenly and displays no streaky areas. Colour differences are well reproduced and gradations are uniform. Viewing angle stability more or less matches the promised 178°.
The Predator X27 offers a maximum brightness of 1000 Nits. The 384 individually adjustable backlight zones offer an excellent static contrast ratio of 1000:1. With HDR, the monitor can achieve a contrast ratio of up to 30,000:1. For a gaming monitor, the colour coverage is incredible: 93% for DCI-P3-, 99% for Adobe RGB and 150% for sRGB coverage. This makes immersion absolutely magical. With the X27, I immersed myself in the game like never before.
The game test
To find out how good the monitor's HDR is, I decide to fire up Far Cry 5, one of the few video games compatible with this technology. The difference between SDR and HDR is considerable. Trees, rivers, characters: everything seems to come to life. How bland life must have been before HDR.
My choice is Deus Ex: Mankind Divided, simply because it's part of my test game collection. Here, the monitor offers a solid display with almost 120 fps. But here too, the test PC is unable to maintain a constant refresh rate. I was forced to reduce my resolution to 1440p. During my gaming sessions, I didn't notice any tearing on the screen.
With a response time of 4 ms (grey to grey), jerks are a thing of the past. The average response time is displayspecifications.com 12 ms and the propagation time is 13 ms. The X27 is therefore at the cutting edge of the demands of its time.
Record
The OSD menu control with the mini joystick is another negative. It looks really cheap when you consider the price of the monitor and its operation isn't very intuitive. Other than that, I have nothing else to complain about.
If you've got CHF2400 to spend and want to invest in one of the best 27-inch gaming monitors, go for it. If your wallet isn't quite as full and your hardware doesn't offer the necessary performance, I'd recommend a 4K/60 Hz screen instead.
From big data to big brother, Cyborgs to Sci-Fi. All aspects of technology and society fascinate me.
