Best motherboard for ryzen 5000

Because they can bring immersive value, larger displays are becoming more and more popular in the gaming community. Although ultra-wide displays were once considered slow, it is not the case for modern alternatives, and many displays now offer high refresh rates and fast response times. In the following article, we will review a monitor that perfectly fits the "fast ultra-wide" category: Acer Nitro XV340CK. The Acer

34-inch monitor is equipped with an impressive IPS panel that can display all the functions required for a high-performance gaming monitor. XV340CK has a fast refresh rate of 144Hz and a low response time (VRB) of 1ms, offering higher specifications than many competitors. It supports FreeSync and GSync adaptive synchronization, provides wide color gamut and 1440p screen clarity, which is very suitable for gaming and productivity. It is also equipped with good color accuracy, wide color gamut and many functions, allowing you to customize the viewing experience according to your specific requirements. On the surface, this monitor seems to check all the correct boxes.

We will gradually learn about XV340CK to see how it performs in terms of price, performance, manufacturing quality and overall price/performance ratio, and compare it with similarly priced alternatives as we proceed.

So, there is a long way to go, let's not waste time, just dive in!

Acer Nitro XV340CK is housed in a fairly basic box, displaying some marketing materials on the outside, as well as the main features and specifications of the display.

Inside the box, the user will find that the monitor and the stand are disassembled. To use the monitor, construction is required. Unfortunately, unlike other monitors of this caliber, XV340CK does not provide tool-free installation. Instead, you must physically screw the bracket plate to the back of the monitor. Although this is not great for speed, it does provide a more robust overall construction.

In the Acer Nitro XV340CK box, you will find the following items:

Aside from the specifications, let's take a closer look at the structural quality, design and mechanical characteristics of this monitor.

Unsurprisingly, the Acer Nitro XV340CK provides the classic "XV series" design features that we see on other panels in the series. The display provides a slim profile, which certainly adds to the premium feel of the panel. The slim bezel provides a near borderless design, which definitely adds to the overall immersion of the panel. The bottom bezel is the largest of the four and features the Acer logo in the center. On the right, when the monitor is active, the user will see a small LED, which emits a blue light. The

stand base has a circular design and has good stability, although it is not as efficient as the "V" -shaped alternative. The base of the stand is also equipped with a small hook-shaped red cable management wiring system. Although not the best I've seen, it can still get the job done.

moved to the back of the screen, not many design features to discuss. Considering the size of the panel, the

bracket adopts a cylindrical design and provides good functions. Most of the back of the panel is rather unremarkable. However, it does have some arrow-shaped carvings inspired by the game, which is definitely more inclined to gamers. The Acer logo can also be found on the back of the monitor.

Overall, XV340CK feels very balanced, providing a universal and game style that can work in both worlds. The quality of workmanship of

XV340CK is surprisingly good. I ran a lot of tests to verify the integrity of the accessories and materials used, and the Nitro monitor performed well in all areas. Unlike other monitors in this price range, XV340CK provides a sturdy metal bracket that can be screwed onto the back of the monitor to increase rigidity. The panel itself feels well-made and doesn't creak or buckle when put under pressure. The panel coating provides a matte coating with 3H hardness, which provides another layer of protection for the panel. The

bracket securely fixes the monitor in place, so it has excellent balance and minimal shake during use. In terms of build quality, the stand base offers the least resistance. It comes with a plastic cover, which doesn't feel overly protective, but isn't entirely scary. The little cable management system at the bottom of the stand feels a bit flimsy too, but honestly, this isn't a big deal.

Like most modern panels, the Acer Nitro XV340CK has an anti-glare panel coating with a matte effect. The efficiency of the coating is very high to brighten natural and artificial light sources. Although it won't protect

This is enough for most users With the help of the picture-in-picture/picture-in-picture function, you can connect multiple different devices and use them at the same time by segmenting the screen. The

OSD is a huge disappointment for me personally. Although other Nitro displays use a simpler joystick method, this is not the case with XV340CK. For whatever reason, they chose to use the buttons at the bottom of the panel on this screen. This method is not only outdated but also absolutely terrifying to use.

In fact, navigating the menu through these buttons is very troublesome, and errors often occur that cause the menu to completely exit. However, in addition to navigation, in the OSD, you have many options to choose from, including color, brightness, brightness, and game settings.

After finding the perfect settings, you can save them to one of a variety of custom configuration files.

Excellent colors and excellent image quality are the two main factors that help you create an immersive feeling when gaming. Although good colors are important, display manufacturers don't always calibrate their panel colors with colors that are considered accurate within a specific color spectrum, such as sRGB / Rec.709.

We like to test the color reproduction of each monitor to see how they perform in a scene 0 with color accuracy.

The following is the Acer Nitro XV340CK output:

As usual, we first quickly tested the factory settings "out of the box"; the configuration of this monitor is; Preset `Standard`, brightness 70, Overdrive set to` Normal`, the color temperature is warm.

Out of the box, XV340CK was a bit disappointed to be honest. We measured a white point of 6952K and a rather unremarkable 0.268 depth of black. The contrast is far below my expectations, and the average DeltaE is largely inaccurate.

This monitor has an analog sRGB profile, so we tested it to see if the colors are more accurate. Strangely, they are not. We got a white point very similar to the factory, but the overall black depth is lower. The contrast is almost the same, the average deltaE actually gets worse, and the average becomes 2.54.

has other color presets to choose from, but none of them are highly accurate. Having said that, here are some observations from the preset:

Action-Colors are very similar to the standard-Overdrive increased to the limit, Freesync disabled and ultra-low latency enabled.

Racing-Negro seems to be slightly improved over the "standard" preset. The contrast is higher and the image seems to use a higher gamma.

Over Drive is reset to Extreme and ULL (ultra low latency) is enabled.

Sports: The overall brightness in this preset is reduced and black is increased. Set Over Drive to "Normal" and enable ULL.

After testing various presets, I quickly calibrated the panel to see how accurate it is.

We used the "User" preset and changed the RGB to 42/46/36. The

results are as follows:

We calibrated the monitor and performed an in-depth color test to understand color accuracy over a wider range. Unsurprisingly, the result is a huge improvement compared to the other provided presets. As you can see from the image above, the white point and black point depth are the most accurate we have tested so far. Contrast is still poor, but the average deltaE has dropped significantly to a near-perfect 0.26, the highest, respectively, 1.83. Gamma now reads as 2.19.

Although this monitor is not the most accurate we have tested, it provides good accuracy when calibrated. Out of the box, this monitor is not suitable for people who want to do color-accurate work. However, after calibration, I can easily recommend it for editing within the sRGB spectrum.

Panel Uniformity is a test we run to verify the brightness and color uniformity of the entire screen. During this test, the central square was used as the reference space. Then test all other squares to see how far it differs from the reference value.

In an ideal world, we want all the squares to be green, which means that it does not break the differential threshold, which we can set at the beginning of the test.

Note: The results will vary from panel to panel. To be honest, the

panel uniformity of XV340CK is a bit unexpected. As can be seen from the above figure, the color scores returned by most of the recorded quadrants are amber or red, which deviates from the color accuracy (and brightness) of the reference square. Many quadrants exceed the 10% threshold, resulting in noticeable differences in the trained eye. Having said that, there is no problem at all with playing games and watching movies. However, if you watch sports events or see programs with large blocks of color, you may be sensitive to the uniformity of this panel.

Although this monitor is equipped with an IPS panel, the viewing angle is not as good as you think. Viewing the monitor from an angle of more than 2530 degrees shows a significant color shift and a significant decrease in overall brightness, which makes the monitor very unsuitable for multi-person use.

It complies with the OK standard and provides 99.3% sRGB, 74.3obe RGB and 80.5° IP3 coverage.

If you look at the actual color gamut diagram, you can clearly see the color gamut scale of XV340CK. The sRGB space beyond the green and red/pink parts (shown by dotted lines). However, it lacks space in blue and orange.

We completed the image quality and color accuracy test by checking the maximum brightness, minimum brightness, and 120 candlelight points on this panel. The result is as follows:

's color accuracy is not affected. It's time to let the Acer Nitro XV340CK experience a variety of different gaming scenarios to see how it performs in terms of pixel response, input lag, and HDR content. Let's dive right in!

Before playing, I found the best scenario to meet my personal needs. Here are the settings:

Over Drive: Normal

FreeSync: Enable

VRR: Disable

Ultra Low Latency: Enable

Playing games on this monitor really surprised me, mainly due to other 34-inch monitors that I have tested in the past. screen artifacts such as ghosting and smearing are severely affected. But this is not so obvious when playing on XV340CK. I loaded up some of my favorite shooting games and the game experience is very nice, although it is not optimized for these types of games. Overall gameplay is surprisingly smooth, with only a small amount of overshoot in fast-moving footage. I tried various Over Drive settings and found that although "Extreme" was showing some signs of overshoot, it wasn't as bad as I expected. Only very few traces of dust can be seen, and when dark objects form a strong contrast against a light background, some signs of halo will be found.

I played some competitive games on the monitor. While this is an immersive experience, it doesn't match the high-speed esports monitors you'll find on the market today. In other words, we record a low input lag of 4 milliseconds, which means that no physical delay is shown between the input of a command and the operation on the screen. When playing various games, the response time of this monitor seems to be quite good, and there is almost no ghosting in the whole process. When playing CS: GO, I did notice some vague feelings, but nothing was particularly noticeable. For casual gamers, this monitor is more than enough for competitive gaming. As you will see on the website, the 1ms rating is done with VRB enabled. That is, without it, you will experience a response time close to 4 milliseconds (GTG). Players of single player games don't have to worry too much about this, because the degree of ambiguity experienced in these types of games is minimal. However, in faster games such as COD and CS: GO, competitive gamers may find this annoying. Also, if you decide to enable the VRB setting, remember that the brightness will be greatly affected. Since this function makes the backlight flicker, the brightness is usually reduced in the process. You must also disable FreeSync to enable this feature. If you cannot maintain a stable frame rate that matches the blinking rate of the backlight, this will increase the chance of screen cracking.

Playing single player games on this monitor is very enjoyable. Color and image quality are the most prominent factors. XV340CK is equipped with a 34-inch 1440p panel, which can display excellent image clarity. Although this is great for immersion, keep in mind that it will put more burden on your system than the 1080p variant. If your PC can handle this resolution, then you will be very satisfied with the image quality provided by this monitor. Finally, the brightness level is a bit disappointing, with a maximum brightness of 250 nits. This causes XV340CK to perform poorly in certain scenes or under sufficient glare.

This is our comprehensive evaluation of the Acer Nitro XV340CK, which is a good 34-inch 1440p monitor that is available at a very competitive price. In terms of gaming and color accuracy, the

Nitro monitor performed well in many ways, mainly due to its fast 1440p IPS panel. The combination of a 144Hz refresh rate and a fast response time of 1 millisecond allows us to get a good gaming experience in fast and slow games. Despite the size of the XV340CK, playing competitive games is actually completely acceptable, with only limited ghosting and excess vision. In other words, this monitor is more suitable for immersive games like "Shadow of the Tomb" and "Cyberpunk". In these games, the perfect combination of large screen size and high image resolution brings impressive Deep viewing experience. Unfortunately, unlike many other 34-inch monitors currently on the market, the XV340CK is not equipped with a curved screen. Although this won't be a deal breaker for some people, it does reduce the market demographics of the group.

In general, it is difficult to beat a monitor of this size and quality when its price is south of $600. For me XV340CK showed excellent value for money at this specific price. Yes, it is not the best monitor I have ever seen, but it is by far the worst and demonstrates excellent quality in terms of gaming, productivity and general use.
