There are many different types of monitors you can buy these days. As technology advances, so do your options. By now you’ll be aware of LCD monitors and TVs and you’ll likely have heard of OLED TVs. However, do you know the difference between the different technologies behind the screens? You may not realize it but the technology that powers your monitor can have a big effect on what you want out of your monitor or TV. This includes color accuracy, latency and viewing angles, and much more. Of course, these differences in technology will make these features better or worse depending on what model you go for. Thankfully, a lot of monitors are rather cheap compared to ten years ago, for example.
In this guide, we’ll take a look at the differences between the various display screens on the market before we measure up the LG Nano IPS monitors and TVs compared with Samsung’s Quantum Dot technology which is some of the most popular choices.
LCD, or Liquid Crystal Displays, is probably the most common display these days and they first became popular over ten years ago when the previous most popular option, CRT displays, became obsolete around the same time due to advances in technology. The old CRTs used vacuum displays, electron guns, and phosphorescent screens to produce images, unlike LCD screens which use liquids to produce colors in a sharp manner. The liquid crystals found in LCD screens are lit from behind by LED lights which help to produce the images on the screen. Older CRT screens were much bulkier than today’s display screens and due to the LCD technology, LCD screens can use the flatscreen technology we’ve all come to admire.
Within the category of LCDs are several types of technologies that help operate the panel which we’ll dissect in the following paragraphs. The most popular types include TN (Twisted Nematic), IPS (In-Plane Switching), and VA (Vertical Alignment).
If you’ve ever owned an LCD display screen then chances are it was powered by Twisted Nematic. LCD screen prices have become so competitive because of TN. They’re very cheap to produce and therefore sell but they’re also very fast. This makes them ideal for casual consumers who just want a decent display screen for use with their computers or to use as a TV.
TN screens are perfect for gamers due to their fast refresh rates of 100Hz and 144Hz. With minimal lag, TN display screens are good ‘all rounders’.
Even though they are cheap, you’ve no doubt noticed the cons of using a TN screen. If you view your TN display screen from the side or from above, you’ll no doubt see the colors change and the sharpness weaken.
IPS display screens have been around for a while now and have been typically used by professionals who work on art, photography, and video editing. This is because IPS display screens have very high color accuracy. Unlike TN display screens, IPS screens can be viewed from many different angles and will retain their sharpness and color accuracy. IPS screens have a reputation of being expensive however they have certainly come down in recent years thanks to manufacturers using cheaper IPS panels.
However, they’re not the kind of LCD screen you want to be used if you’re a gamer expecting a high frame rate because IPS displays have slower refresh rates. Still, they’re the perfect choice for professional work and won’t break the bank anymore.
VA display screens sit somewhere between TN and IPS screens. They are not as expensive as IPS screens and they also have reasonable refresh rates. VA screens can also be viewed from different angles and retain a good amount of color accuracy and sharpness so they make for good TVs with seating facing them from various angles, for example.
The high latency of VA display screens means they suffer from the same issues and IPS screens for gamers so you may experience ghosting effects on your screen. Again, this isn’t ideal for gamers but if you’re not fussed about having the fastest refresh rates and a bit of potential blurring, a VA screen may be a good option if you can’t afford an IPS screen.
Quantum Dot display screens are not LCD display screens at all. That’s because they use a whole different and arguably superior technology to light the actual screen. Where LCD screens typically use blue LED lights to light a white screen in front of them, Quantum Dot screens are powered by tiny dots that convert into the light. This makes Quantum Dot technology superior to LCD screens because they are capable of outputting a more uniform white light that can be individually tuned to cover more of the screen.
OLED or Organic Light Emitting Diode is a completely new technology where each OLED pixel is capable of producing its own light. This removes the need for a backlighting system like the ones found in LCD screens. Because each pixel can be turned on and off individually, OLED screens have the most perfect black screens and the purest of white screens, and superior overall color accuracy as well as brightness. OLED screens can also be viewed from a number of angles and retain their sharpness, brightness, and overall picture quality. OLED screens produce the most life-like images on your monitor. It’s understandable that OLED monitors are high in price, not to mention hard to come by. Because this technology is so new, it’s safe to say it will be a few years until the price is driven down by other companies releasing their own monitors with the technology.
Two popular options for these two technologies are coming through LG’s Nano IPS monitors and TVs and Samsung’s Quantum Dot monitors and TV range. Both of these display technologies do nearly the same thing yet they still have their slight pros and cons.
Nano IPS are best for a wider color gamut of up to 98% DCI-P3 or 135% sRGB while the QD technology by Samsung is best for higher contrast and brightness.
For the sake of comparing both the Nano IPS technology and the Quantum dot technology, we’ll be comparing the LG 27” Class UltraGear™ QHD 144Hz Nano IPS 1ms Gaming Monitor with G-Sync® and the 27″ CFG73 Gaming Monitor with Quantum Dot from Samsung. Both of these monitors are made for gaming and both have significant features for creating flawless gaming experiences.

The 27″ CFG73 Gaming Monitor is another fantastic monitor for gaming. With its rich contrast, you’ll get the greenest greens and the richest reds. With 3x the contrast ratio of the LG Nano (3000:1), it makes for a perfect monitor for playing colorful games on. Its resolution is fair but it does lag behind the LG Nano Dot Monitor. It has the same viewing angle as the LG Nano so there’s no difference there.
LG Nano IPS vs Samsung Quantum Dot: TVs
LG Nano IPS TVs and Samsung Quantum Dot TVs offer the same experiences as their monitor cousins but you’ll be able to experience their features on much bigger display screens.
First, we’ll take a look at the pros and cons of each TV technology.
LG Nano IPS TVs
Starting price: $600
|Impressive color gamut||Expensive|
|Good viewing angles||Average contrast|
If we use the LG Nano91 55 inch 4K TV as an example, we can see just how impressive Nano IPS technology is in TVs. These large TVs can be viewed from all angles and not drop in quality thanks to the Nanoparticles that light each corner of the screen. These particles are packed so tightly together so you’ll never see any ghosting effects. And because each particle produces its own light, you get the truest colors on your screen. This means the darkest of blacks (without grey haze) however, the brightness of these displays is not the best on the market especially compared to the Quantum Dot.
At the core of LG NanoCell TV is the α7 Gen4 AI Processor 4K, a groundbreaking chip that uses machine learning algorithms to analyze and optimize content. Every adjustment to picture and sound is automatic, so everything you watch will look great.
Samsung Quantum Dot TVs
Starting price: $600
|Brilliant whites||Average blacks|
|Brilliant contrasts||Light bleed|
Much like Quantum Dot monitors, Samsung Quantum Dot TVs offer a high contrast ratio thanks to HDR and brightness of up to 1000 nits which is reported ‘as bright as 1k candles’. Images are photo-realistic on Quantum Dot TVs and as a light source, a billion different color combinations are created to express the most realistic images on SUHD TVs’ 10-bit panels. That’s 64 times more color expression than conventional 8-bit panel TVs.
Samsung Quantum Dot TVs also feature Ultra Black which effectively disperses light from your screen so there’s no need to close your blinds to get rid of screen glare. You can sit back and enjoy your movie without any light changes. Another impressive piece of technology featured in Quantum Dot TVs is their Remastering ability. Your TV will automatically ‘remaster’ your show or movie to look the best it possibly can in real-time.
Whilst Samsung’s Quantum Dot TVs have impressive whites, their blacks could do with a little refining. Some users also report ‘light bleed’ which can be common with Quantum Dot TVs. This is where the edges of a bright image can seem blurry unless you are set directly in front of your TV, unlike Nano IPS TVs where you can get a perfect image from any viewing angle.
The Bottom Line
It’s fair to say that both of these technologies offer impressive experiences as far as display screens go. Both are still quite new and could do with some refining though. The Nano IPS TVs offer fantastic viewing angles without risking blurring or sharpness, however, contrasting could use some tweaking. The Quantum Dot display screens from Samsung give you fantastic contrast in colors and blinding brightness in light scenes during films and games but still struggle to produce the deepest of blacks and you may experience slight light bleed from time to time.
