Acer’s Super-wide EI491CRG9 is a 240Hz Mini LED Monster

The Chinese retailer Taobao has revealed Acer’s upcoming EI491CRG9, an ultra-wide 5120×1440 (dual-wide 1440p) monitor that offers users a 240Hz refresh rate and over 2,000 local dimming zones. 

While this screen has a funny name, this monitor’s specifications are no laughing matter, shipping with AMD’s FreeSync Pro and Nvidia’s GSync Compatible certifications, and a massive 49-inch VA Mini LED display. 
 
Not only will Acer’s new EI491CRG9 monitor feature higher peak brightness levels, but it will also offer users improved contrast levels. The Mini LED technology inside Acer’s EI491CRG9 (seriously, why such a complicated name?) display enhances this monitor’s VA panel to offer users 2,048 local dimming zones, allowing this screen to produce darker darks and brighter highlights. While this will not enable the same contrast levels as OLED-based screens, mini LED will deliver similar results in many instances and superior results to edge-lit HDR monitors.

Mini-LED screens minimise the halo effect of low-end HDR implementations, enabling higher contrast levels higher quality HDR experiences. Acer’s use of a Mini LED HDR display should make their new EI491CRG9 (Let’s shorten this to “G9”) monitor a superior solution for viewing HDR content. 

Acer’s new ultra-wide G9 monitor has also been listed as a monitor that’s G-Sync compatible and supports AMD’s FreeSync Premium Pro technology, allowing gamers to benefit from tear-free PC gaming and increased smoothness when gaming on the monitor. Acer’s 49-inch G9 is a perfect monitor for racing games, first-person shooters, and simulation games like Microsoft Flight Simulator, offering gamers a wide aspect ratio, VRR support and high maximum refresh rate. 

With a Quantum Dot display panel and support for 10-bit (1.07b colours) colour depths, Acer’s new EI491CRG9 is suitable for content playback, gaming and some colour sensitive work, offering 95% coverage of the DCI-P3 colour space. It is worth noting that Taobao list this monitor as a 12-bit screen, but also claims that this screen can produce 1.07 colours, which is 10-bit. Enhanced image processing may allow this screen to take in 12-bit colour inputs and produce somewhat better results than standard 10-bit monitors.
