LG's New UltraGear Monitor launched in India

LG's New UltraGear Monitor launched in India

A few weeks ago LG India launched World's first 4K 144hz Nano IPS 1ms(GTG) gaming monitor in the country. The company named it as 27GN950 UltraGear gaming monitor.

Display Features

The New LG Ultra Gear Monitor is a 27 inch(68.58cm) Ultra HD(UHD) 4K 144hz monitor delivering a screen resolution of 3840 x 2160 Pixels with a nano IPS display. The monitor has a hi-speed refresh rate of 144 Hz on offer which is going to make the gaming experience more fluid. The monitor has one of the fastest GtG(Grey to Grey) response time of 1ms which means that its pixels can change colors in 1ms, which is a pretty fast process. Talking about the screen specifications, the monitor is equipped with a Nano IPS display which offers a better experience with the help of nano-meter sized particles. The monitor has DCI-P3(Digital Cinema Initiatives – Protocol 3)

98% Color Gamut of CIE1976 type due to which the device can offer 1.07 Billion colors. The monitor has a Pixel Pitch(Distance from the center of one pixel to another) of 0.1554 x 0.1554 mm offering a standard aspect ratio of 16:9. The monitor is a VESA(Video Electronics Standards Association) display HDR 600 certified monitor which means that it can deliver peak brightness of 600 cd/m2 and its VESA certification assures that you can go with this product undoubtedly. The monitor supports DSC(Display Stream Compression, published by VESA in 2014) which enables visually lossless compression between the application processor and the display sub-system inside UHD devices. To get the 4K performance at 144 Hz, the device should be paired with a graphics card supporting DSC. Talking about the display type, it is an IPS(In-Plane Switching) display which offers very accurate colors and has better viewing angles of 178º (R/L), 178º (U/D) compared to the other type of displays(TN and VA). Also, the 1ms response time makes it the best because earlier IPS displays used to offer low response times and frame rates. The very main feature of this monitor is that it supports both Nvidia's G-Sync and AMD's FreeSync Premium Pro due to which, the problem of screen tearing and ghosting is eliminated. The screen has 400 Nits of Brightness with a contrast ratio of 1000:1 on offer which is pretty high and much needed for a gaming monitor

Connectivity

 The UltraGear monitor comes with 2 HDMI ports, 1 Display port needed for Nvidia G-Sync to work, also a 3.5 mm Headphone port, 1 USB Up-stream port  for connecting peripherals(like Pendrives, etc.), and 2 downstream ports for connecting devices. The device does not have built in speakers.

Power Specifications

The device is fueled by a 100-240 Vac input power supply operating at a frequency of 50/60 Hz consuming 65 W of maximum power. 

Extra features

Apart from the above-mentioned features, the device has more on offer. The very eye-catching feature is the sphere RGB lighting strip installed at the back of the monitor which responds to the Sound(with Sound Sync Mode) and Video(with Video Sync Mode) to create a better interactive experience. Apart from this, the monitor has PIP(Picture in Picture) to offer which lets you project screens of different devices in one screen. It also has a Black Stabilizer feature that Brightens the gamma in dark scenes so that you "have an advantage in games which have more dark scenes." It also supports Dynamic Action Sync which reduces display lag and helps in gaming. The monitor is equipped with Crosshair which will help you in first-person shooting games that don't offer Crosshair for aiming. It has a Flicker safe screen which prevent the monitor from flickering and also provides you a Reader mode focused mainly on the health of your eyes. The monitor supports HDR 10 which will help you deliver high dynamic range. It also has an Active dimming feature which adjusts light automatically and conserves energy. The major feature of the monitor is FreeSync (Low Frame Compensation) which works when the frame rate falls below the minimum refresh rate of the monitor. When the frame rate drops below the minimum refresh rate of the device, frames are duplicated and displayed multiple times so that they can sync to a refresh rate that is within the display's refresh rate range.

Dimensions and weight

It has got a 27-inch screen and weighs around  5.71 KG. It comes with a 110mm stand offering a tilt angle of 5-15 degrees.

Now as you read about all the features but you might be confused about the parameters. So now we will explain to you that "What is What?":

(a). What is Refresh Rate?

Do you know Video is nothing but a sequence of images(called frames) playing on the screen at a high frame rate of 30 fps(frame per second) normally? The refresh rate is the rate(no. of times) at which the frame changes in a second. The higher the refresh rate, the more fluid will be experienced. Higher refresh means that the human eye will not be able to notice the change of frames(because the human eye can notice up to 10-15 frames per second) and the viewing experience will be much better. In comparison to movies, the frame rate of the Games is very high which needs a device supporting high frame rates. Nowadays monitors support a minimum refresh rate of 60 Hz which is good for average gaming but new games have higher frame rates which need monitors of higher refresh rate. If the monitor refresh rate and the frame rate of the game do not match then there are chances of Screen tearing which means that the screen will show two unloaded frames due to the impropperly synchronized frames. To tackle this problem Nvidia graphics card has G-Sync and AMD has FreeSync which displays a Variable Refresh Rate (also known as VRR or a dynamic refresh rate) and synchronize its minimum and maximum refresh rate. 

(b). What is the Response Time?

Response time is the time taken by the pixel to respond after getting the input from the user. This monitor has a 1ms GtG(Grey to Grey) response time which means that it is the time taken by the monitor to change the color from one shade of grey to another. It is basically the time taken by the monitor to shift from one color to color but here we refer to grey color because the screen emits grey light which is used to emit different colors with the help of filters. The GtG offers lower values so that's why manufacturers use this number to track the customers. There is another parameter called BtW(Black to White) response time method which produces high numbers or slow times because the little tiny crystals in the LCD screen go from the "off position" (black) to the "on position" (white). This method gives higher time and that's why it isn't written in the product description.

(c). What is DCI-P3(CIE1976)?

It is a standard that is used by products to measure the colors which are visible to human eyes. Earlier CIE 1931 standard was used but due to its nonuniformity in colors, it is not used. DCI-P3 represents color spaces or color gamut. It attempts to scientifically represent the natural color as seen by the human eye to reproduce color. The DCI-P3(Digital Cinema Initiatives – Protocol 3) offers a 10-bit display that offers 1.07 billion colors.

(d). What is DSC(Display Stream Compression)?

DSC is a method devised by VESA to deliver the which enables visually lossless compression between the application processor and the display sub-system inside UHD devices. It reduces power consumption and decreases the display’s frame buffer size which further decreases cost. Any device with VESA certification can be trusted blindly because VESA certification is meant to deliver the best performance. 

(e). What does the contrast rate mean?

Contrast rate is the ratio of Luminescence(the intensity of light per unit area) of bright shade to the dark shade of light. A higher contrast ratio means a better display. 

(f). What do 400 Nits mean?

Nit is just a different term given to "Candela Per square meter" where Candela is the brightness of a Single average Candle. N number of candela means the brightness of N candles. So one candela per square meter (or one nit) is the brightness of one candle shining onto a surface that measures one meter across and one meter down. Putting that into simpler terms, imagine that you’re holding a piece of paper that measures one meter by one meter. You then light a single candle and hold it up in front of the paper. The amount of light that hits your paper from the candle is equal to one unit (or one candela per square meter or cd/m2). Higher the Nit, the brighter and better the display.

Recently LG has also launched a 32-inch monitor which has a 4K 165 Hz refresh rate and can be overclocked to 180 Hz. Also, a 34-inch monitor with a 21:9 aspect ratio is launched and the company claims it to have a 5K panel with a resolution of 5120×2160 pixels supporting HDR 10.
