The reflection handling is superb; thanks to its matte material screen, you won’t see any glares nor reflections.

Additionally, the entire design has an excellent matte-black plastic material that feels durable and high quality, making the design look futuristic yet straightforward as well. You can find the Acer logo on the top left rear of the panel, adding to the entire build’s authentic feel.

And with an excellent aesthetic look, the stand is ergonomic by design and has a circular base-shaped, which serves as a solid foundation for the XV340CK. Thanks to its small circular base, the stand will save you room and space for your table as well.

The stand can adjust in height 150mm, tilt, and swivel; however, it cannot pivot. But you can always swap the stock stand for a 100x100mm VESA mount for more display flexibility and more motion range.

Along with its ergonomic stand, you’ll find the connectivity located on the rear of the display, consisting of two DisplayPort 1.4, two HDMI 2.0, two USB 3.0, and one headphone jack. With an abundance of connectivity, you can transform the XV340CK into a hub of connectivities.

In addition, the contrast ratio sits at 1000:1 and has a brightness level of 250 cd/m², which are all standard for an IPS panel. Usually, blacks are a bit grayed out in dark sceneries,

Being an IPS panel, the XV340CK remains consistent in terms of color and imagery; however, colors and imagery start fading when viewing the screen at certain angles.

The monitor has a 99% sRGB coverage making it solid for creatives and photo editors, thanks to its wide variety of the color spectrum. And the display has outstanding SDR coverage as well.

In addition, the overdrive feature works great; however, it’s best to turn off the overdrive feature because graphical artifacts and overshoots may start appearing. You may have to calibrate the overdrive and the refresh rate settings for this feature to work optimally. But the monitor allows you to choose from regular to extreme overdrive settings.

Also, the Acer Nitro XV340CK is excellent for your eyes as well; thanks to its flicker-free backlight, you can use the display for prolong hours without any eye strains.

The VRR ranges from 20Hz – 144Hz, and FreeSync overall will give you a better immersive experience.

Input lag sits around 4ms, which is fantastic for gaming, and you won’t experience any delays in graphics and images.

There was a bit of backlight bleeding around the edges and corners of the display; however, it’s not that too significant and shouldn’t be an issue.

Also, if you’re operating the XV340CK for the first time without any calibration, the monitor will grant you great colors and performances. The colors may be off by a slight degree, but you can quickly fix this by calibrating the display.

Once you’ve calibrated the monitor, you’ll receive outstanding color coverage, and you’ll be able to obtain the rich darks and brilliant lights in extreme lighting settings.

Overall the XV340CK is an excellent gaming monitor. With 5 MP and a pixel density of 110 PPI, and a 21:9 screen aspect ratio, the display will give you more than enough screen real estate to perform your best.
