The 27-inch 1440p is by far the most common type of computer screen. There are a lot of options with refresh rates of at least 144 Hz and Adaptive-Sync, and the prices are all over the place. You can find a barebones model for under $400. But extra features like a faster refresh rate, RGB, blur-reduction, HDR, or a more accurate extended colour gamut will cost you more.
As of this writing, the Acer Predator XB273U NVbmiiprzx does all of the above at 170 Hz and is G-Sync compatible for about $550. With DisplayHDR 400 certification, more colours, and the solid build quality that is typical of Acer’s Predator series, it stands out in its class and competes well with the best gaming monitors.

Acer Predator XB273U review: Design

The Predator XB273U F shows how Acer’s Predator design language is usually used. Its matte black-on-black look is mostly understated, but the back has some texture and style. Unexpectedly, there is no RGB lighting at all, so gamers will have to bring their own. The quality of build is good. The plastic parts of the monitor feel thick and strong. The display has thin bezels, but the bottom chin is big, and the back panel is thick, which gives it a sense of being strong and durable.
Acer has a wide stand that looks like a tripod and has strong metal feet. It’s big and heavy, has a lot of ergonomic adjustments like height and rotation, and does a great job of keeping the monitor steady. Its wide legs, on the other hand, take up a lot of space on a desk. The monitor has the standard 100x100mm VESA mount, so a monitor arm or stand from a third party can be attached. You can buy this monitor from its official website.
Acer Predator XB273U review: Features
In the back, there are three video inputs: one DisplayPort 1.4 and two HDMI 2.0. The only way to use the monitor’s full 25601440 resolution at 360Hz is through the DisplayPort 1.4 port. That’s a shame, but it seems to be the norm right now. This is a problem that is shared by monitors like the Asus ROG Swift PG27AQN.
The monitor has audio out and four USB 3 Type-A ports that are driven by one USB Type-B port. That’s a good number of ways for a gaming monitor to connect. The USB-A ports are hard to get to, which makes it hard to connect a USB thumb drive or SD card adapter.
Acer Predator XB273U review: Controls

The Picture menu on the Acer Predator XB273U NV has basic controls for the brightness of the screen, as well as low blue light modes, ACM, also known as dynamic contrast, HDR, LightSense, and Super Sharpness. You can set HDR to “Auto” to have it automatically switch between signal types, but HDR games look best when you choose “HDR400.”
Acer Predator XB273U review: Display and Performance
About a year ago, Acer announced that they would be adding three new monitors to their impressive Predator series. The newest displays would be part of a new Predator XB3 lineup. They would have great performance specs that could put them at the top of the gaming market.
In this article, we’ll test and review the Acer Predator XB273U, one of the three monitors that were announced in June 2020. The XB273U GS is a 27-inch gaming panel with all the bells and whistles, like a fast refresh rate of 165Hz, a low GTG response time of 1ms, and a screen resolution of 2560 x 1440p. The XB273U gives you an IPS experience and has VESA displayHDR 400 and 95% of the DCI-P3 colour gamut certifications.
Final Words
The Acer Predator XB273U GX is a great monitor for playing games. It has an overclocked refresh rate of 270Hz and excellent response times, both at its maximum refresh rate of 270Hz and at 60Hz. It works with both FreeSync and G-SYNC, but VRR doesn’t work with the overclock setting, and it locks in overdrive, which may be annoying. The input lag is very low, but it’s a little bit higher at 60Hz.

This is one of the best IPS monitors available. This monitor is just as good as ones that cost twice as much. Even better than the OLED panel on my gaming laptop, in terms of clarity and brightness.
Are predator computers good?
The End of the Story. The Acer Predator Helios 300 is still a good deal among gaming laptops with a 15.6-inch screen, but it doesn’t stand out in a very competitive market.
