How to choose monitors for your desktop computers
It is very important to choose a good monitor, sometimes even more important than choosing your computer. Why? First of all, a monitor will accompany you longer than a computer, and it also affects your health.
I bought a 24” LCD/LED monitor with speakers 10 years ago, cost less than $200, it still works very well. I need a second 24” LCD/LED monitor currently, it cost me $270 on Amazon and no speaker, the image has the same quality with my old one, surprisingly the value increases over time, not like my computers.
There are different purposes for monitors. If you're playing games or watch video often, you'd like faster responsive time and higher resolution. You should choose a 4K monitor. But you may need to buy or upgrade your video card to be able to use it. The best panel type is IPS, it continue to be the display technology that provides better color accuracy and consistency.
To reduce eye strain, buy a high frequency, IPS, TUV certified Flicker free monitor. If you buy a small or medium monitor, 1920X1080 pixels, 60Hz, 5ms should be enough. For a 27" or bigger monitor, it's better to go with increased frequency and resolution, like 4K, 75Hz or above. IPS monitors are said to be better than regular monitors because of their consistent and clear presentation of colors.
After your monitor is shipped to you, you can check some common defects to make sure the quality is satisfactory.
The way to check is to set the whole screen on black, white, red, green and blue
colors. Here's a tool to help you check.
Check Computer Monitor Pixel
Here are some monitor defects you can easily check by yourself:
Dead Pixels and Stuck Pixels
Most manufactures won't allow you to return if there're defects with only a few pixels. However, if there's a group of defective pixels together, they'll replace your monitor.
When your screen is black, you can see the lights around the border, this especially noticeable with cheap monitors.
If the black color is uneven, it's called monitor clouding. This issue is usually produced in manufacturing process or because of too much pressure during shipping.
IPS glow is the backlight shining through the WHOLE panel at sharp viewing angles. It's a problem inherent to IPS technology, but if it's too bad you can return it. Otherwise, you can find some solution online to reduce the effect.
