Screen and image quality

The LG 20MK400H-B monitor is one of the best gaming monitors on the market today. The TN panel offers low input lag and response times making it a great choice for gamers looking for an immersive experience with no distractions.

Quality monitors have a history of withstanding the test of time. But this monitor has come under scrutiny for its image quality at certain viewing angles, specifically those beyond 60º vertical and 95° horizontal viewings.

It’s important to know how to read an angle as it can be difficult not to see any other parts of the screen if you’re looking from afar.

The image is crisp and bright, but it’s not 1920×1080. The screen has a 1366 x 768 resolution which means the picture will be sharp on any LCD monitor that size – perfect for work from home!

The images on the panel are not any less pristine than they would be in person. The panel’s colours look a little washed out, but that is to be expected when viewing them from an angle and without much light.

The overall display type performance for gamers will satisfy their needs with low input lag, brighten dark scenes and high refresh rate, and excellent response times- just two milliseconds!

Screen and image quality of LG 20MK400H-B

Scientists have found that people who buy the LCD monitor to watch series, movies and especially edit images are unhappy with washed-out colors.

This is unfortunate because this means they won’t enjoy a full range of color on their screen. However, if you’re more interested in using your monitor to display pictures or graphics, it’s not as bad news since its resolution isn’t Full HD (1080p) but instead 720P, which should still look great on older consoles like PS4 and Xbox One.

Now that you know the biggest problem with this LCD monitor is its image quality, it’s easier to decide if buying LG 20MK400H-B will be worth your money.

The best selling monitor on supermarket shelves is ideal for use as a secondary computer screen. In addition, with its low price and excellent cost-benefit ratio, this makes an outstanding deal even without color accuracy.

Features and performance

The LG 20MK400H-B has the cheapest HD LCD monitor of this brand for anyone looking to buy an affordable computer screen. This model does not have imaging features that you find in more expensive models, but it is still a great product. It performs well due to its panel with a low audio input lag and response time of 2ms.

Features and performance of LG 20MK400H-B

Flicker Safe helps you to protect your eyes from exhausting flickers. Dynamic Action Sync mode allows you to instantly react and attack opponents without any display lag! It synchronizes senses with real-time scenes in fast-paced games by minimizing input lag.

Since these are things most gamers care about, we recommend this as long as your video games run on 720P resolution; otherwise, there would be better options like the LG 24mk430 if playing 1080p

These features make it a pleasure to use, even for hardcore gamers. The monitor’s Dynamic Action Sync feature, in particular, allows the frames displayed on your screen to remain synced with what is being shown by your video card. This eliminates any lag that may occur when playing one of today’s more popular FPS games like Overwatch or Fortnite and provides an improved gaming experience overall!

Despite its basic design, this widescreen monitor screen includes modern technology that helps reduce eye fatigue and headaches typically present after prolonged periods using standard HD LED monitor without these beneficial technologies- blue light reduction plus Flicker level Safe work together as you game throughout the day while also reducing glare so that you can see all it is available at once; meanwhile, both are compatible with every PC system out there due to their

The LG 20MK400H-B is a good LCD monitor for work, studies and especially reading. It offers “Reader Mode”, which reduces blue light on the screen to make viewing more pleasant without straining your eyes too much. The device also features Screen Split 2.0 software that lets you split screens into different parts so they can be used simultaneously by multiple users or apps at once–although this function would not benefit from such a small actual size as it cannot fit side-by-side with other gaming monitors of similar HD resolution anyway–but could come in handy if working on two large display option one after another while is wanting access to windows across both screens (e.g., browser tabs).

Construction and durability

The construction of this LCD monitor is standard, with mostly plastic and a rectangular base. It does not have the height or rotation adjustments. Still, it offers VESA 100 × 100 mm drilling allowing the user to place it on panels for better ergonomics at their desk rather than only having an inclination adjustment.

Can circumvent as it also includes a good support panel that allows you to adjust both height and tilt/rotation functions if desired.

There are few reports of burnt pixels or defects, such as a light leak in this model. However, we recommend that you purchase from a trusted store like the ones we mentioned in this review to avoid headaches with after-sales and make sure there is no damage before buying it.

Despite being a good and cheap monitor, it is not disposable, so if that’s what concerns you, then don’t buy one because LG displays are reliable, even their cheapest models, which can see here too!

LG 20MK400H-B review the connections of the monitor

In our opinion, this is an excellent monitor that doesn’t leave you without any connectivity options at all!


LG’s 20MK400H monitor is a good gaming monitor for those looking to enjoy an immersive gaming experience. The Dynamic Action Sync mode ensures that you can respond instantaneously in fast-paced games without any lag from the display, which will provide gamers with more opportunities than ever before. You get all of these and customizable options as well!

The low-definition panel technology, HD resolution and screen size allow the image to be unclear. Especially if you’re going to watch movies or TV series on it, with OnScreen Control, you can more comfortably read your monitor screen with joystick control. This easy-to-use user hardware interface makes viewing easier on the eyes and reduces eye fatigue for long periods in front of screens.

This LG 20-Inch monitor is not just for work or school-related tasks, but it also has a gaming mode. The AMD FreeSync technology syncs the displays with compatible graphics cards to reduce ghosting and blur while playing games. You can customize your display options with a few simple clicks.

The on-screen control is a godsend for users who prefer to adjust their monitor settings without having to fumble around with physical buttons.

This Lcd monitor is not for this; instead, it’s meant for people who need a basic HD monitor at the home office while using their notebook as second screens – study and read when needed so they can work efficiently in any field of expertise like Photoshop without having a high definition quality display or an expensive model with many features that will do more harm than good over time because of its design flaws such as weight imbalance caused by batteries which make them prone fall from a height even though there is another item model available. Still, unfortunately, LG has stopped selling digital monitor for them due to some reason we don’t know about.

Let’s be honest; the LG 20MK400H-B is not a perfect monitor. It has its flaws, but if you’re looking for a display technology with all of the bells and whistles at an affordable price, then this one will do just fine. You get more than what you pay for when purchasing this actual product—if that matters to you!
