In this article, I discuss whether or not the Acer 21.5" KA222Q Abi monitor is good for gaming. I also list which aspects are important for choosing a gaming monitor to understand what you should get for your needs.
Below, I rank each aspect of the Acer 21.5" KA222Q Abi to determine if this monitor is good for gaming. There are four rankings total: excellent, good, mediocre, and poor.
- The Refresh Rate of 75 Hz is good
- The Response Time of 1 ms is excellent
- The Resolution of 1920 x 1080 is good
- The Color Capability of 90% DCI-P3 is excellent
- The Display Panel Type of VA is good
The refresh rate of the Acer 21.5" KA222Q Abi is 75 Hz, which is good for gaming.
Refresh rates determine how well a monitor can handle motion — the higher the refresh rate, the better.
Most gaming monitors have a refresh rate ranging from 75 Hz to 360 Hz.
Refresh rate is the number of times a display can redraw the screen. Refresh rate is measured in hertz (Hz), which is defined as one cycle per second. For example, a refresh rate of 60 Hz means the screen will redraw 60 times each second.
What Is a Good Refresh Rate for Gaming?
An optimal refresh rate for gaming is around 120 Hz to 165 Hz or above. Refresh rates in this range will reduce motion blur and make animations smoother. The downside to higher refresh rates is that it takes a higher-end graphics card to reach a faster framerate to take advantage of a faster refresh rate. For example, for a 120 Hz display, you will only get the whole experience if your graphics card can produce a framerate of 120 fps. It's still usable under 120 fps, but it won't be as smooth during fast movements.
The response time of the Acer 21.5" KA222Q Abi is 1 ms, which is excellent for gaming.
Response time also determines how well a monitor can handle motion — the lower the response time, the better. Typical gaming monitors usually have a response time of 1 to 6 ms.
Response time is the time it takes a display to change from one color to another. This timing is usually determined by going back and forth between white and black. The timing is measured in milliseconds, with lower being better.
You'll notice more ghosting if your monitor has a higher response time. When ghosting occurs, it looks like the colors are blurring together whenever there's quick movement on the screen.
What Is a Good Response Time for Gaming?
Try to get a monitor with a 1 ms response time for best results. Monitors with a slightly higher response time (e.g., 5 ms) can still make for a great gaming monitor if you don't mind some minor ghosting.
Some monitors are not capable of both being set to their highest refresh rate and achieving their fastest response time. Check the monitor specs to determine what it supports.
The resolution of the Acer 21.5" KA222Q Abi is 1920 x 1080, which is good for gaming.
The amount of detail and image crispness is based on the resolution, but a bigger screen allows you to see it at a more comfortable size. The types of game details can include textures, user interface elements, and text quality.
For a 27-inch monitor, a resolution of 1440p (3440 x 1440) picture will look a lot more crisp compared to 1080p (1920 x 1080) resolution. The numbers in the resolution stand for the number of pixels per line. So a 1920 x 1080 resolution monitor would have over 2 million pixels total.
Brandon Jones / TechReviewer
The Acer 21.5" KA222Q Abi has a 90% DCI-P3 color gamut, which is excellent for gaming.
Color Gamut is the color range that is produced on a display. The higher/wider the color gamut, the more colors the monitor can display.
Determining what is most important when choosing a monitor depends on which color space (CMYK, sRGB, DCI-P3, or Adobe RGB) you usually use. It's best to select a monitor with a wide range of colors; the higher percentage, the better. The DCI-P3 color space is the most popular and has the widest range of colors.
VA is the display panel type of the Acer 21.5" KA222Q Abi, which is good for gaming.
The display panels inside monitors can use a variety of different technologies. Common LCD panel types include TN, VA, and IPS. Non-LCD panel types include OLED.
Panel Type Comparison
Below is a comparison of the different monitor panel types. Overall, IPS panels are our personal favorite because they provide the best features for the price.
We also include OLED TVs since they can be used as monitors due to their excellent motion handling, colors, and contrast.
Note that LED and QLED are types of backlight technologies and are used in combination with TN, VA, and IPS panels.
