You are unlikely to choose a gaming monitor according to the available connection interfaces, but we could not pass by this column in the technical specifications. At the moment, all fast monitors are required to be equipped with modern DisplayPort and HDMI ports. With DVI-D and, especially, D-Sub, they said goodbye a long time ago.

2022 update: Top 10 gaming monitors under 300 - choosing the best gaming monitor

The response rate is the time taken to display the state of a pixel, which is activated when the color changes. Response rates are expressed in milliseconds, and a monitor designed for gaming must have a response rate below 5ms, otherwise blurry effects will appear. For example, character data or the name of a sign in the game can periodically become blurry or even unreadable, which greatly reduces the sense of presence:

There are three main types of monitor matrices: Twisted Nematic, Vertical Alignment and In-Plane Switching. So, IPS provides high quality, but is much inferior to TN. On the other hand, a TN sensor provides less quality in color and contrast, while a VA sensor offers a good contrast ratio and rich colors, but can cause blurring, which is not suitable for action games. Therefore, for games it is better to choose a TN matrix.

Compatible with Freesync and G-Sync

Some gaming monitors are compatible with Freesync or G-Sync, technologies developed by AMD and NVIDIA that allow the display to use a variable refresh rate to synchronize with the GPU.

Freesync technology is based on a free standard compatible with HDMI and DisplayPort ports. And the G-Sync standard requires the addition of a module to the screen, which increases its cost but provides better performance as well as greater dynamic range. However, G-Sync is only compatible with DisplayPort ports.

Please note that some monitors are compatible with both standards.

Nvidia Fast Sync

In the chest, Nvidia has Fast-Sync software technology hidden deep in the driver settings and is a direct alternative to V-Sync. It appeared not so long ago, and therefore many users do not even know about its existence.

It does not require special monitors to work, it works on absolutely any models (even with the declared support for FreeSync). The main thing is that your system has an installed video card with an Nvidia GPU, preferably from the last two generations, and a new driver version.

The usual V-Sync allows you to deal with tearing relatively effectively, but it has significant disadvantages: input lag and fps limitation. Fast-Sync also removes frame tearing and micro-lag, but there is no increase in input lag that negatively affects the gameplay. Comparing with G-Sync, we can note the quality work of Fast-Sync at a very high fps level (100 and higher), but if the frame rate floats in a wide range (for example, from 40 to more than 100 fps), then the hardware solution turns out to be more efficient. But for this, as you already understood, you will have to pay a good extra.
