4K models with high vertical refresh rates can be treated differently. Some were waiting for them like manna from heaven, while others believe (and performance tests confirm this) that there is no point in them and will not be until GPU manufacturers raise the bar for the speed of their graphic solutions by 2-3 times from the current indicators.

2022 update: Best 144hz monitor under 300 - choosing the best gaming monitor

The human eye is able to determine the difference in the smoothness of the displayed movement up to 1000 frames per second.

Movies are perceived smoothly at 24 fps due to the peculiarities of the human brain, which independently completes the missing information between frames. This phenomenon is called motion blur (blur) and when watching a video is perceived more naturally than when watching a scene generated by a computer - see details here https://thetimes.digital/games/best-gaming-monitor-under-300/.

High frame rates and screen refreshes affect not only the smoothness of the image, but also the accuracy of displaying the location of moving objects.
On a monitor with a frequency of 60 Hz, the effect of a higher frame rate is noticeable, but not to the full extent, so we will concentrate on models that support 120 Hz and above in advance.

Response time and refresh rate are not directly related to fps in games

The terms "refresh rate", "response time", "input lag" and "frame rate" are related to how smoothly and clearly motion is displayed on the screen. These are related but completely different concepts.


"Framerate" (fps, frames‑per‑second, frames per second) has nothing to do with the monitor at all. This is the number of frames that the video card produces and sends to the screen in one second. This number can be higher or lower than the supported refresh rate.
The “refresh rate” or “vertical frequency” of a matrix is ​​measured in hertz and indicates how many times per second the matrix can completely change the image. The more frequently the image on the screen is refreshed, the smoother the movement of objects is perceived. This is noticeable not only in games, but even when moving the cursor on the desktop or scrolling through pages in the browser.

The second reason to consider high-resolution models is the desire to see more on the screen without having to swipe and open tabs. Of course, the size of work items and text will be smaller (when comparing models with the same diagonal), but the quality of detail will be high. Work will become more comfortable, and productivity will increase. In the case of games, the difference will be more determined by the aspect ratio than the working resolution. The only thing you can count on when it is increased is a decrease in the size of some interface elements, graphic blocks and text. But how important it is for the player is a big question!

The third and most important point for those who like to play is the difference in the load on the computing components of the system. Most of all, this affects the graphics subsystem for complex calculations. And if Nvidia GTX 1050 Ti (and GTX 1060 for high quality settings, and with a margin of several more years) can now be enough for games in Full HD resolution with medium graphics settings, then for WQHD it is better to look towards GTX 1070 and 1070 Ti, for UWQHD (3440×1440) - on GTX 1080 and 1080 Ti, and for a comfortable game in 4K, it is advisable to save money for new generation cards - and then you can not think about replacing in the next 1-2 years (if you are very lucky). However, if stable 30-40 fps is enough for you or you agree to medium and low graphics settings, then the list of suitable options can be safely expanded.
