Overview

When it comes to the advantages of the best gaming monitor under 400, you will probably witness the virtual world games in reality. It comes with a new large vision which helps users have a comfortable experience, so that it is not wasted when pouring money into this kind of product which develops your gaming environment in the future. Therefore, the article of Ocster will focus on the best gaming monitors under 400 and the things that you should consider when buying a gaming monitor that fits your needs.


Buying Guides

In our society today, hardware vendors understand how the experience changes with multiple display specs as well as features and have flooded the market with a bounty of options.

However, do you know which features as well as specs are most valuable for your monitor? Do you know the way to distinguish between 4K, 1440p, 1080p or just plain HD resolution? How should your priorities change if your discussion is gaming versus professional applications versus general use? As well as how much you will spend on your monitor?

In the next section, to help you know a little bit more about what you should be concerned about when selecting a monitor to purchase from the best gaming monitor under 400 in 2021.

1. Curved monitor

In case you are going to search for a curved monitor, it will be supposed to make your experience more immersive with a large vision, then it is said to be less eye-straining. However they can be prone to glare when viewing from certain angles since light sources are coming from various angles instead of one.

It is thought by manufacturers that effective curved monitors are usually ultrawide and at least 34 inches as the VIOTEK GNV34DBE 34-Inch Curved Gaming Monitor , which both point to higher costs.

2. Size of monitor

When it comes to which size is suitable for your budget and space-containing, a larger monitor will have low pixel density if it's a lower resolution so that viewing from typical desktop distances, 27 inches is plenty big.

It’s not hard to find a 27-inch gaming or general use monitor at 1080p resolution for under $400 such as the ASUS TUF Gaming VG279QM 27” HDR Monitor and the LG Electronics UltraGear 27GN750-B.

3. Refresh rates

Due to the fact that the bigger refresh rates, the better monitor you have. This refresh rate shows you the number of times your monitor updates with new information per second as well as is measured in hertz (Hz). On the other hand, the bigger numbers equal better, the smoother, less choppy pictures.

This feature also has an especially impact on gamers, who'll want a monitor with at least 75 Hz although most monitors designed for gaming offer at least 120 Hz, combined with the lowest response time you can find. If you’re a gaming player, a 144 Hz refresh rate such as the VIOTEK GNV34DBE 34-Inch Curved Gaming Monitor or the LG 27GL83A-B 27 Inch Ultragear   may be fit for your needs.

4. Resolution

The resolution plays a big role in a gaming monitor, the higher the resolution, the better the picture you have. A monitor’s resolution will show you how many pixels a monitor has in width and height format.

For instance, with 1920 x 1080, which is also known as 1080p, Full HD (FHD) and HD as the ASUS TUF Gaming VG279QM 27” HDR Monitor, is the minimum you need for your gaming setting. However, you'll get sharper images with QHD as well as even sharper with 2560 x 1440 quality such as the VIOTEK GNV34DBE 34-Inch Curved Gaming Monitor.

5. Response times

Turns to the response time, it shows you how long a monitor takes to change individual pixels from black to white or, if it's GTG response time, from one shade of gray to another.

If your monitor offers longer response times, like the LG 27GL83A-B 27 Inch Ultragear with 1ms response time, this can mean motion blur when gaming or watching fast-paced videos.

With gaming monitors in the market at the moment, the highest response time you seem to see is 5ms, while the fastest gaming monitors can reach a 0.5ms response time.
