Acer XR382CQK


The Acer XR382CQK gaming monitor offers an incredibly immersive and engaging gaming experience unmatched by any display we’ve reviewed so far. Its gigantic 37.5-inch screen along with the ideal 2300R curvature wraps your entire peripheral vision with stunning details and vibrant colors.

Additionally, the monitor provides you with rich connectivity options and a plethora of gaming features including AMD FreeSync technology. The cinematic thin-bezel design also offers versatile ergonomics and a premium build quality.

It’s comparable to gaming on a huge, curved gaming TV but without the responsiveness and blurring issues as the Acer XR382CQK delivers flawless input lag and response time performance.

Image Quality

Right out of the box, the Acer XR382CQK image quality will simply amaze you without any tinkering required. The monitor is based on LG’s AH-IPS panel that supports 10-bit color through dithering (8-bit + FRC) and covers 100% of the sRGB color space. Besides the impeccable accuracy, colors deliver perfect uniformity and consistency with excellent greyscale performance.

The same IPS panel is featured in the LG 38UC99 monitor as well. The viewing angles are 178° vertical and 172° horizontal which ensures that there is no color or contrast shift when the screen is viewed from basically any reasonable angle. There was no bothersome backlight bleeding nor IPS glow visible.

The UWQHD+ screen resolution of 3840×1600 (6,144,000) pixels is somewhere in-between 4K (8,300,000 pixels) and the more common 3440×1440 (4,953,600 pixels) ultra-wide resolution.

On a 37.5-inch UWQHD+ display, the pixel density amounts to 110 pixels per inch which is the perfect ratio between screen real estate and picture detail, without any scaling necessary.

This also means that you will need considerably less GPU horsepower to fluently run video games on this display than on a 4K monitor, yet the image simply overflows with details.


Having a powerful AMD FreeSync compatible graphics card will allow you to synchronize its frame rate to the display’s refresh rate. The consequent dynamic refresh rate fully eliminates screen tearing and stuttering within its FPS (Frames Per Second) rate range.

The Acer XR382CQK FreeSync range amounts to 48-75Hz though LFC (Low Framerate Compensation) isn’t supported which means that the dynamic refresh rate stops working once it drops below 48 Hz/FPS. Therefore, according to your computer gear, you may need to lower some visual effects in more demanding video games.

Most games support or perfectly scale to the 21:9 aspect ratio, and may only switch back to 16:9 during some cinematic cutscenes in certain games. In any case, check whether your favorite games support the ultra-wide format or you may have to stick with playing with black borders on the sides.

The Acer XR382CQK IPS monitor offers 5ms (GtG) response time speed which efficiently removes most of ghosting and trailing of the fast moving objects. Naturally, for competitive gaming, you would need a monitor with faster response time, smaller screen size, and higher refresh rate. For casual gaming, working, and watching movies, the Acer XR382CQK does wonders.

Additionally, you can boost the response time speed via the Overdrive function and thus reduce motion blur, but it cannot be active at the same time as AMD FreeSync technology. The Acer XR382CQK input lag amounts to only 13ms which is more than enough for responsive gameplay.


The Acer XR382CQK display is packed with exclusive features including pre-calibrated picture presets (Action, Racing, Sports, Standard, ECO, Graphics, Movie, Custom), advanced 6-axis color adjustment, customizable on-screen crosshairs, and an FPS counter as well as the common adjustments such as brightness, contrast, gamma, sharpness, PiP and PbP modes, etc.

Another useful feature is the Dark Boost which increases visibility in darker games. Furthermore, in the OSD (On-Screen Display), you can customize the 12 ambient lighting LEDs which are placed across the bottom part of the cabinet. LED customization consists of combining five colors and four effects.

The OSD menu is effortlessly navigatable via the joystick placed behind the display. The three buttons above it can be assigned as shortcuts to certain OSD functions. The Acer XR382CQK is flicker-free and has a blue light filter which allows for comfortable viewing experience even after long hours.

Design and Connectivity

The design is of premium quality featuring a metal V-shaped stand with versatile ergonomics including 130mm height adjustment, 60° swivel, 40° tilt, and 100 x 100 VESA mount holes.

The screen is coated with an anti-glare 3H treatment against the sunlight reflection. The Acer XR382CQK is absolutely huge with 35.3″ in width and 18″ in height (23″ at max height adjustment), so make sure you got a big enough desk!

The extensive connectivity consists of an HDMI 2.0, an HDMI with MHL 2.1 for content streaming via compatible devices, a mini-DisplayPort, a DisplayPort, and a DisplayPort-Out for daisy-chaining multiple monitors.

Additionally, there’s a USB-C port which can transfer files, stream video/audio, and charge a device at the same time. As if it weren’t enough, there is a USB hub consisting of one upstream and four downstream USB 3.0 ports as well as two 7W built-in speakers with excellent DTS sound quality.

Price & Similar Monitors

The Acer xR382CQK price amounts to $1,093 at the moment (September 2017). LG’s version, the LG 38UC99 offers nearly identical specs though it’s priced at $1,660. It has Bluetooth speakers, but a more limited 52-75Hz FreeSync range. Either way, the Acer XR382CQK is a better choice for the money.

Within the same budget, you may also consider the Acer Predator X34 with Nvidia G-SYNC and 100Hz refresh rate; Or, the more affordable Acer XR342CK which is essentially a smaller version (though still big) version of the XR382CQK.

For less money, you could get a 1440p 144Hz, a 240Hz, or a 4K G-SYNC gaming monitor. So, visit our gaming monitor buyer’s guide for more information.


The Acer xR382CQK 3840×1600 display is the biggest gaming monitor out there, however, its size is not its only impressive asset.

There’s more than enough connectors, the design is gorgeous and versatile, and there is a plethora of useful features.

Unless you’re a hardcore competitive gamer who relies on faster response time speed and higher refresh rates, you will certainly fall in love with the Acer XR382CQK.
