Quantum Dot Display

Samsung has lately been incorporating nanotechnology in their LCDs to improve the viewing experience. The Quantum Dot technology features quantum dots. Quantum dots are nanoparticles that can not be seen by the naked eye. These particles are added to layers by the manufacturers.

The basic purpose of the Quantum dot is to enhance the colors and brightness. Quantum dot displays get a richer and more vibrant color scheme and the HDR on the is far more desirable.

The LCDs incorporated with  Quantum dots provide the same results as the OLEDs available in the market. Quantum Dot LCDs are cheaper than the superior-priced OLEDs. Ever since the introduction of the Quantum dot more and more brands have opted to use Quantum Dot in their advertisements.  

Wide Color Support

The display features a one billion color support. This means that the color detection on the display is very sharp. It can be seen that repetitive testing by various reviewers showed that the display features an amazing color accuracy.

In almost all color gamut, the colors for the C27HG70 proved to be above par. The accuracy of the display was second to none. Although with such an amazing color accuracy by viewing closely it can be seen that the display has some off centers.

An off-center is a point where dimming can be observed in a display. For this specific magnificent curved display, the off centers are surprisingly the corners of the display. The vividness in colors can be observed on the display. 


The display features a Quad HD display setup. The depth and details of the pixel enhance with the  Quad HD display feature. Therefore the resolution on this display is like no other. It provides a high-quality viewing experience. 

High Refresh Rate

Refresh rate is one of the most important aspects of any display in the modern world. It means how many times a display can update pictures in a second. Since the game developers have enhanced the quality of games over the years, so has the refresh rate increased.

The Samsung Q27HG70 features a staggering 144Hz refresh rate. At this refresh rate, it can play almost all games and videos with ease.

Furthermore, to enhance the viewing experience for the customer Samsung has provided users with the option to adjust the refresh rate using the on-display menu to limit the refresh rate between 60Hz to 120Hz.

Response Time

As important as the refresh rate if the response time is not calibrated with the refresh rate the display will show lag. Lag in this scenario means an action appears later on the display as originally performed.

Nothing is as frustrating as a lagging display. Samsung has made sure that their display features no lag at all because of which the response time on the display is 1ms which is fast enough for the naked eye to even detect any lag. 


This beautiful display by Samsung is available in two sizes. One is the 27-inch standard display the other is the 32-inch display. The displays are the same on and off paper in terms of specs. The only thing that differs between the two is their sizes only. 

Headphone Plug-in

The display for the convenience of the customer features an on-display headphone plug-in. This plug-in allows the user to conveniently listen to the audio by plug-in their earphones or headphones directly into the monitor rather than the computer. 

Multiple Built-in Modes

The On-display menu is quite exceptional as it provides the customer with a lot of options. The basic preset image modes include; sRGB, Custom, Cinema, and high brightness. These are the standard modes recommended for daily use only.

In addition to the standard modes, there are quite a few gaming-focused modes available too. Such as the FPS, RTS, AOS, and  RPG gaming modes. To provide a little bit more ease to the customers all of these many modes can be easily accessed and edited by the customer according to their preferences.   


Samsung CHG70 review

The design of the display is just phenomenal. You can talk and talk and talk about it and it still won’t be enough. The stand for the display is a v-shaped neck with a sleek base. The stand allows the display to be erected horizontally or vertically.

The display can be leaned up and down left and right according to your requirements. The monitor itself has a curved shape and that just sucks you right into the display. This monitor is meant to be used for hours. 


The key highlight for today has been the HDR feature introduced in this vertical alignment display. Some also call it a Super Vertical Alignment monitor because of the viewing experience and the mighty 144Hz refresh rate.

When it comes to HDR, the most important factor in displaying HDR content is having a sufficient contrast ratio, while color reproduction and brightness also play a role. OLED displays have a good contrast ratio out of the box, but LCDs usually need localized backlight control to render various parts of the picture dark and light enough. 


Although there aren’t any speakers on the display there are ample ports for you. The display features a trio of HDR-supported ports. It features a DisplayPort 1.4 and 2 HDMI ports on it. Furthermore, there are 2 USB-3 ports on the display. 

AMD Freesync

What is AMD freesync?

It’s awesome to see AMD FreeSync support return, and the C27HG70 now supports AMD FreeSync 2, with a confirmed FreeSync range of 48-144Hz. You will experience crystal-clear, tear-free HDR gaming at the highest frame rates when you use a Radeon RX series card with the new Polaris architecture.
