4K Gaming Monitor Key Features

If you are in the market for the best 4k gaming monitor 2021, you must know a few features to keep in mind before choosing which display should grace your desk.

FreeSync & G-Sync

While playing high-end video games on traditional monitors equipped with V-Sync technology, you will witness enough screen tearing ruining the whole gaming experience. To tackle this issue reducing screen tearing and introducing the lowest possible input lag, 4K HDR monitors are packed with G-Sync and Free-Sync technologies. G-Sync is an Nvidia’s adaptive synchronization technology that works up to the mark eliminating enough screen tearing, but they are comparatively high-priced than Free-Sync. Only Nvidia graphics card equipped monitors are compatible with G-Sync technology. Next, the Free-Sync adaptive synchronization technology is meant to reduce screen stuttering and comes with optimal refresh rates. They come at a low price than G-Sync and are only compatible with AMD graphics cards.

Vieving Angle

Best 4k curved gaming monitors equipped are with ideal viewing angles giving you the opportunity to look at the display screen from anywhere you want and still witness clear images with no shades or color inversion. Viewing angles with 180 degrees are considered the best to bring the optimal gaming experience even if you are looking at the display screen quite at some angle or distance. IPS panels (In-plane switching) are observed to offer the best viewing angles than others in the competition. TN panels (Twisted-Nematic) work well keeping other factors in perspective, but suffers with providing the best viewing angles.

Response time

Response time is referred to how fast the display screen changes its individual pixels. The best 4K gaming monitors come with response time equal or closer to 5ms, anything higher than that, for a 4K best gaming monitor, is considered as not the optimal one. TN (Twisted-Nematic) display panels play well on this battlefield, comes with faster Response time than the IPS and VA panels. Keeping the figure low as much possible can help the monitor to reduce disturbing screen smearing while playing fast-paced games. Keeping this precise not mixing them up, input lag mostly is considered the same (Response time), but in reality, input lag is something that refers to the delay between input and the on-screen result. TN panel with the lowest response time is 1ms.

Refresh Rate

When you are mostly looking for first-person shooting games like counter strike etc, the monitor’s refresh rate is even more vital. It is measured in Hertz and refers to how fast a 4k gaming monitor changes images on the display screen. The higher the refresh rate, the more the screen will feel responsive to high-end video games, making the gameplay smoother and lag-free. Most of the conventional gaming monitors possess a refresh rate of 60 Hertz, but one with 144Hertz and 200 Hertz refresh rate should be well prominent.

Screen Aspect Ratio

The screen aspect ratio refers to the display’s height and width-wise adjustment. The typical 4:3 square format aspect ratio screen is considered as pretty much not the best option to play games with, in 2021. There are screens coming up with larger 21:9 aspect ratios getting much of pro-gamers attention. 16:9 display screen aspect ratio is adopted by many of the manufacturers. It feels extremely amazing while playing professional games on the best 4k gaming monitors with a larger aspect ratio.

Display Resolution

Along with response time, viewing angles, panel type, and all other aspects, there is one another critical factor to consider when searching for an ideal monitor and that is display resolution. The resolution refers to pixels count on screen. If the pixels count is greater, ultimately you will be able to witness clear sharp results. The display resolution is coupled greatly with screen size, you will need to have a 14 to 17 inches screen size for FHD resolutions (1920 x 1080, Full High-Definition), similarly, WQHD and 4K resolutions will urge you to have at least 17 inches display screen size.

Panel Type

Panel type is where things get a little complicated and technical. The TN display panels (Twisted-Nematic) comes with a budget-friendly price tag, offers the best response times when compared to IPS and VA panels, the only issue with twisted nematic panels is that they are not the best if you are specifically looking for a monitor with rich viewing angles. The IPS panels (In-plane switching) offer out of the box color production and optimal viewing angles but they suffer providing faster response time. VA panels (Vertical Alignment) packs features of both TN and IPS but they are not used much in the gaming industry. Twisted nematic panels are preferred more because of their budget-friendly tags and minimal response time.
