LG 4K vs. LG OLED: Which One Wins?

LG offers a variety of televisions featuring various screen types, technologies, and resolutions. Buying a new TV from the brand can easily become confusing.

Comparing LG 4K and LG OLED, for instance, is one of the most common mistakes. The former refers to resolution, while the latter is image technology. Comparing them is like comparing apples to oranges, as OLED TVs can come in a 4K resolution. This is also the case in comparing the brand’s UHD, NanoCell, and QNED TVs. Learning the difference between these types could help you pick the right one for you.

Let’s break down everything you need to know about the different display types here so you can figure out which one fits your viewing needs best.

LG 4K vs. LG OLED: What’s the Difference?

LG manufactures a wide range of 4K TVs, but you can’t really compare LG 4K and LG OLED televisions. That’s because the former defines a resolution (3840 pixels × 2160 lines, to be precise), while the latter is a display technology. In fact, OLED stands for organic light-emitting diode, which is a type of LED. Hence, if you want to decide which 4K TV from LG is best for you, you have to compare OLED with 4K UHD, NanoCell, and QNED televisions.

Display Type

The main difference between OLED and the other 4K TVs from LG is the display type.

LG OLED displays are made with organic light-emitting diodes. These LEDs feature self-lighting capabilities, meaning that each pixel can be turned on and off independently from the others. These self-lit pixels don’t require a backlight either and can deliver exceptional quality colors and higher contrast. OLED televisions are also the only type of 4K TVs from LG that can display pure black, which translates into better details in shadow.

LG's 4K UHD TVs stand at the opposite end from OLED. Their display is a regular LCD with LED backlights. These televisions can’t turn on and off each pixel independently, and basically, the screen is divided into different dimming zones that can be turned on and off as needed. Due to this reason, they can’t achieve pure black, and the color accuracy is inferior to OLED.

LG's NanoCell TVs are superior to 4K UHD, but they still feature an LCD with LED backlight. The main difference is the NanoCell technology, which refers to a coating of nanoparticles with a diameter of one nanometer applied to the screen. These nanoparticles improve the way the display reflects light, enhancing color accuracy and increasing the viewing angle.

QNED is an LG-proprietary technology that combines quantum dots with NanoCell technologies. These TVs are LCD-based with mini LED backlighting that divides the screen area into about 2,500 dimming zones. They feature the same nanoparticle coating seen in NanoCell, plus they benefit from the quantum dot technology that increases color gamut and richness. These TVs are the closest in quality to LG OLED.

Image Quality

Regardless of the display type, all TVs mentioned above feature the same 4K resolution. This doesn’t mean the image quality is the same, though. The 4K UHD models have the lowest image quality with good but not outstanding colors and contrast. That’s because these televisions feature LCD screens and standard LED backlighting. This translates into faded colors compared to the other types and poorer dimming.

The smaller processor and a refresh rate of only 60Hz are also responsible for some motion blurring, especially during fast-moving scenes. NanoCell TVs deliver better image quality due to the enhanced colors, but the basic models in this range feature the same process and refresh rate of the 4K UHD. Hence, blurring could still happen.

Superior image quality in LG’s 4K line is found in its QNED and OLED televisions. The former features the same nanoparticle layer found in the NanoCell models, but the mini-LED backlighting increases the number of dimming zones. The colors are better defined and more true-to-life, while enhanced contrast improves image clarity in shadows. LG’s QNED TVs also feature a better processor and a refresh rate of 120Hz, which minimizes blur.

The same is true for OLED TVs, but these impress with even higher color accuracy. Due to the self-lighting pixels, they are the only TVs to deliver pure black color and the highest level of contrast. Image quality is exceptional, but you’ll have to shell out a lot more cash for all these perks.

OLED TV
OLED TVs are widely considered to be the best TV type, with true-to-life images that make any game or movie pop right out of the screen.

Sizes  

An important thing to consider when buying a TV is the screen’s diagonal size, which eventually determines the full size of the device. Knowing its diagonal can help you decide which TV fits in your space, be it small or large.

In today’s market, finding a large TV isn’t difficult at all, and all 4K TVs from LG have diagonals up to at least 86 inches. If you have a very large living room or want to fill a larger wall, you’ll have to opt for an OLED TV, which is the only type with a diagonal that goes up to 97 inches.

For smaller rooms, all 4K TV types except for QNED start from diagonals of 43 inches. The smallest QNED options have 55 inches in diagonal. The bezel size (depth of the TV) goes from 2.9 inches in the 4K UHD to 1.8 inches in the QNED and OLED models.

Gaming

TVs are the core of a home’s entertainment system, their function going beyond watching TV channels or streaming Netflix. You can use them to play video games, too, either pairing them with your PlayStation or Xbox or by downloading and playing games directly from the LG store –- after all, that’s what smart TVs are made for.

However, you won’t have endless options on all models. For the most basic 4K UHD, the models only feature auto low latency mode (ALLM) and cloud gaming from Google STADIA, in addition to compatibility with Xbox, PlayStation, and other gaming consoles. NanoCell models are surprisingly similar (and lacking options), but they feature cloud gaming from Nvidia GeForce Now.

More gaming capabilities come from the QNED and OLED models. The former features a variable refresh rate and premium free sync, while the latter has everything seen in the QNED plus a response time of under one millisecond. Gaming features on LG’s OLED TVs also include G-sync compatibility.

QNED vs LED
QNED relies on a full array of mini LEDs for its backlight type, and it’s a superior choice for gaming.

Energy Efficiency

Another crucial difference between these 4K TVs from LG is energy efficiency. None will make you go bankrupt –- the least efficient option would only cost you around $40 per year in electricity – but you could save a tenner or two with one of the more efficient options. As you’d expect, the least efficient are the 4K UHD TVs, which have an average annual power consumption of 249kWh and typical power consumption of 135 watts.

QNED and OLED TVs come next, with annual power consumptions estimated at around 200kWh and 222kWh, respectively. The most energy-efficient TVs from LG are the NanoCell, with a typical power consumption of only 94 watts and an estimated annual power consumption of 174kWh.

LG 4K vs. LG OLED: 7 Must-Know Facts

LG 4K vs. LG OLED: Which One is Better for You?

From a strictly technical standpoint, the LG OLED is the best 4K TV from the brand. This television features the best picture and audio quality, fast AI processing, and excellent streaming and gaming capabilities. However, this doesn’t mean it’s the best LG TV for you.

If you don’t have an excessive budget or don’t want to break the bank, a NanoCell or even QLED model will save you some cash. Those on a low budget might even be satisfied with a 4K UHD as long as they’re aware of the TV’s limitations. In the end, this television has a decent image quality and overall satisfactory capabilities.

LG 4K and OLED Technology Updates
