What is high refresh resolution? How to achieve it?

  High refresh resolution refers to the situation where the refresh rate and resolution of the monitor are relatively high, such as a 2K monitor with 144Hz, or a 1080P monitor with 240Hz. So what are the benefits of high refresh resolution?
  What are refresh rate and resolution?
  First of all, we need to understand what refresh rate and resolution are. Refresh rate refers to the number of pictures that a monitor can display per second, in Hz. Resolution refers to the number of pixels displayed on a monitor, usually expressed in horizontal pixels and vertical pixels, such as 1920x1080 is a common resolution.
  Both refresh rate and resolution affect the picture effect we see. Generally speaking, the higher the refresh rate, the smoother the picture, without the feeling of stuttering and tearing; the higher the resolution, the clearer the picture and the richer the details. So many people hope to have a high refresh resolution monitor to improve the viewing experience of games or videos.
  What are the advantages of high refresh resolution?
  So what are the specific advantages of high refresh resolution? We can look at it from two aspects: visually and operationally.
  Visually, high refresh resolution allows us to see smoother, clearer, and more realistic pictures. This is very important for some games with beautiful pictures, fast actions and complex scenes. For example, "Cyberpunk 2077", "Call of Duty", "League of Legends", etc. High refresh resolution allows us to immerse ourselves in the game world better and feel the charm of the game.
  In terms of operation, high refresh resolution allows us to have faster, more accurate and more stable reactions. This is very critical for some games with strong competitiveness, high operation requirements, and reaction speed and precision. For example, "CS:GO", "Rainbow Six", "Honor of Kings", etc. High refresh resolution allows us to better control the characters in the game and improve the winning rate of the game.
  What conditions are required for high refresh resolution?
  Of course, if you want to enjoy the benefits of high refresh resolution, it is not enough to just buy a high refresh resolution monitor. You also need to consider several other conditions: host, monitor, cable, interface.
  01. Host: The host refers to the device that runs games or videos, such as computers, laptops, hosts, etc. The host needs to have strong enough performance to output high frame rates and match the refresh rate of the monitor. Generally speaking, high refresh resolution has relatively high requirements for the host, especially the graphics card. For example, if you want to achieve a refresh rate of 144Hz at 2K resolution, you need a graphics card with good performance, such as the GALAX GeForce RTX4070 Star OC 12GB. If the host performance is not enough, there will be screen freezes, frame drops, tearing and other phenomena, affecting the gaming experience.
  02. Monitor: A monitor refers to a device used to display images, such as LCD monitors, OLED monitors, etc. The monitor needs to have a sufficiently high refresh rate and resolution to display high-resolution images. Generally speaking, high-resolution monitors are more expensive, especially IPS panels and VA panels. For example, the Philips 27-inch 279C9 is an IPS monitor with a 4K resolution and a 60Hz refresh rate, suitable for watching videos and office work; the AOC 27-inch 27G2 is an IPS monitor with a 1080P resolution and a 144Hz refresh rate, suitable for playing competitive games; the AOC AGON 27-inch AG274UXP is a Nano IPS monitor with a 2K resolution and a 144Hz refresh rate, suitable for playing quality games.
  03 Cables: Cables refer to cables used to connect the host and the display, such as HDMI cables, DP cables, DVI cables, etc. Cables need to have high enough bandwidth and speed to transmit high refresh resolution signals. Generally speaking, high refresh resolution has relatively high requirements for cables, especially HDMI cables and DP cables. For example, to achieve a refresh rate of 144Hz at 4K resolution, you need a cable that supports HDMI 2.1 or DP 1.4 or above. If the cable is not good enough, the picture will be blurred, the screen will be distorted, and flickering, affecting the viewing effect.

  04. Interface: Interface refers to the jack used to connect cables on the host and the display, such as HDMI interface, DP interface, DVI interface, etc. The interface needs to have a high enough version and specification to support high refresh resolution signals. Generally speaking, high refresh resolution also has relatively high requirements for interfaces, especially HDMI interface and DP interface. For example, to achieve a refresh rate of 144Hz at 4K resolution, both the host and the display need to have interfaces that support HDMI 2.1 or DP 1.4 or above. If the interface is not good enough, there will be phenomena such as the inability to output images, black screen, no signal, etc., which will affect the use of functions.
  In short, high refresh resolution can allow us to see smoother, clearer, and more realistic images in games or videos, and can also give us faster, more accurate, and more stable responses. However, in order to experience the charm of high refresh resolution, we also need corresponding hardware, including host, display, cable, interface, etc.
