Also, the monitor has wider color coverage meaning it can show a wide variety of colors and hence improves color accuracy.

    Moreover, color reproduction on this monitor is in its league of its own. Once calibrated, it delivers excellent color reproduction. However, the two disadvantages of this monitor are one, its poor viewing angles. Eventually, the color accuracy and brightness as viewing from side decreases notably. Another disadvantage is its lower peak brightness. It is only problematic if you are using it in a very bright room or under direct sunlight.

    Otherwise, it is a very impressive monitor for movies or streaming and gives an immersive viewing experience


    An important aspect many people might be sensitive to is flicker. It is important, especially when looking at monitors for longer times like in gaming or movies. Thankfully, it has no signs of visible flicker. Talking about other factors, it has a very impressive pixel response time of 4ms, which is fast than most other monitors. It also supports AMD FreeSync technology which matches fps to screen refresh rate in the range of 48 to 60 Hz. It can eliminate screen tearing or stuttering in that limited range.

    The stand of the monitor is solid and doesn’t let this huge monitor wobble too much. It is also painted in a matte black color similar to the monitor.

  5. Acer Nitro XV340CK: Best Overall

    Acer Nitro XV340CK - Best monitor overall


    Screen Size: 34 inches | Resolution: 3440 x 1440 | Panel Type: IPS | Refresh Rate: 144 Hz | Response time: 1 ms | Native Contrast Ratio: 1000 : 1 | Peak Brightness: 250 nits | Ergonomic: Tilt: -5° to 35° only| Ports: 2 x Display Ports, 2 x HDMI 2.0 & 2 x USB 3.0 Ports | Variable Refresh Rate: AMD FreeSync | HDR: HDR10 | Speakers: 2 x 3W

    • Excellent pixel response time
    • 144 Hz refresh rate
    • Color accuracy and consistency
    • Lower peak brightness
    • Limited ergonomic options

    Acer Nitro XV340CK is a monitor that does not excel at all the criteria like gaming, editing, or watching movies in particular. Rather it is a monitor that combines the characteristics of all other monitors into one at a moderate level. This makes it the best monitors under 400 overall.

    Picture Quality:

    Acer XV340CK’s 3440×1440 resolution, 34-inch huge screen translates to a pixel density of about 110 PPI (pixels per inch). This makes everything sharper and immersive whether it is high res gaming, or QHD movie watching experience, or editing photos or videos.

    It has an IPS panel which means colors are accurate, consistent, and vivid. Color coverage on this monitor is pretty decent, with 99% sRGB coverage it has enough variety of color. It has a true color depth of 8 bit producing 16.7 million colors.  It supports HDR10 which will provide a more dynamic range, bright, and vibrant colors. The viewing angles are great on this monitor. No distortion visible even though it has a flat ultrawide display.

    Moreover, the Acer XV340CK has a peak brightness of 250 nits. It is okay for normal conditions, unless in very bright rooms or under direct sunlight as glare would overcome the screen visibility. Also, you might see some backlight bleeding. It is normal with IPS panel and the bleed is not bothering.

    Overall it is a good viewing experience on this ultrawide monitor.


    The Acer XV340CK delivers a very low pixel response time of 1 ms with VRB(Visual Response Boost ) enabled and a lower input lag of about 5 ms. That is extraordinary and improves overall gaming performance.

    It packs FreeSync support, which improves gaming performance by eliminating screen tearing and stuttering. FreeSync changes the refresh rate of the monitor on the go to match the fps without compromising much of the input lag.

    The AMD FreeSynch works in the range of 48-144Hz. If fps goes below 48, the frames rates are multiplied to give you smoother performance. This is cool. Although Acer XV340CK does not support G-Sync automatically, it can be enabled manually.


    The monitor stands on a circular based stand which provides firm support to this huge ultrawide monitor with minimal wobble. The stands look standard and it is painted black. The stand only offers -5°/35° tilt adjustments. Thankfully, it is VESA compatible mount.

    Moving on to the monitor itself, it looks nice overall. It has thinner look with super-thin bezels all around except for than big chin. Both monitor and stand are made of high-quality plastic material and doesn’t feel cheap.

    Connectivity options on Acer XV340CK includes 2 x HDMI 2.0 ports, 2 x DisplayPort 1.4, a headphones jack, 3 x USB 3.0 (1 upstream and 2 down), and a dual 3W integrated speakers.
