Their 2023 TV lineup showcases some of the most advanced display technologies available to consumers, with the LG G3 OLED and LG QNED Mini-LED TVs sitting at the top of the range. As a digital technology expert, I‘ve delved deep into the specifications, features, and performance of these two cutting-edge TVs to help you determine which one reigns supreme. In this comprehensive comparison, we‘ll explore the intricacies of OLED and QNED technologies, analyze real-world performance data, and provide insights to help you choose the perfect TV for your needs and budget.

Understanding the Technologies: OLED vs QNED

OLED: Self-Emissive Pixels for Perfect Blacks

OLED (Organic Light Emitting Diode) technology has revolutionized the TV industry in recent years, offering unparalleled picture quality thanks to its self-emissive pixels. Unlike traditional LED-LCD TVs, which rely on a backlight to illuminate the pixels, each pixel in an OLED TV can emit its own light. This allows for perfect black levels, as pixels can turn off completely when needed, resulting in infinite contrast ratios. LG‘s OLED TVs use a WOLED (White OLED) panel structure, which consists of a white light-emitting layer with color filters on top. This differs from Samsung‘s QD-OLED (Quantum Dot OLED) technology, which uses blue OLEDs with quantum dot color converters.

QNED: Mini-LED Backlighting with Quantum Dot and NanoCell Technologies

LG‘s QNED (Quantum Nano-Emitting Diode) technology represents a significant advancement in LED-LCD TV performance. QNED TVs combine a Mini-LED backlight with Quantum Dot and NanoCell technologies to deliver improved brightness, color accuracy, and local dimming compared to traditional LED-LCD TVs.

The Mini-LED backlight consists of thousands of tiny LED lights that can be individually controlled, enabling more precise local dimming and higher contrast ratios. While QNED TVs can‘t match the pixel-level control of OLED, they typically offer several hundred to over a thousand local dimming zones, compared to the millions of self-emissive pixels in an OLED TV.

Quantum Dot technology enhances color performance by using nano-sized semiconductor particles that emit specific colors when exposed to light. This allows QNED TVs to achieve a wider color gamut and more vibrant, lifelike colors. NanoCell technology, on the other hand, uses an extra layer of nanoparticles to filter out unwanted wavelengths, resulting in purer colors and wider viewing angles.

LG G3 OLED: The Ultimate in Picture Quality

Exceptional Brightness and Contrast

The LG G3 OLED TV builds upon the already impressive performance of its predecessors, offering even higher peak brightness levels and more precise color accuracy. According to RTINGS‘ measurements, the G3 can achieve a peak HDR brightness of around 1,470 nits in its Vivid picture mode, a significant improvement over the previous generation LG G2 OLED (around 1,000 nits). This extra brightness allows the G3 to deliver stunningly impactful HDR performance, with highlights that truly pop off the screen.

Of course, the G3 OLED also maintains the infinite contrast ratios that OLED technology is renowned for. With the ability to turn pixels off completely, the G3 can display perfect blacks right next to bright highlights, creating a level of visual depth and realism that LED-LCD TVs struggle to match.

Wide Color Gamut and Viewing Angles

In terms of color performance, the LG G3 OLED covers an impressive 99% of the DCI-P3 color space and around 80% of the wider Rec. 2020 gamut, according to HDTVTest‘s measurements. This means the G3 can display a vast array of colors with exceptional accuracy, bringing content to life with vivid, lifelike hues.

Another strength of OLED technology is its wide viewing angles. The G3 maintains excellent color and contrast performance even when viewed off-center, making it an ideal choice for larger living rooms or seating arrangements where not everyone can sit directly in front of the TV.

Advanced Gaming Features

The LG G3 OLED is also a top-tier gaming TV, offering a range of advanced features to satisfy even the most demanding gamers. With a native 120Hz refresh rate, low input lag (around 5ms in its Game Optimizer mode), and support for VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode), the G3 delivers a smooth and responsive gaming experience. It also supports NVIDIA G-Sync and AMD FreeSync Premium for tear-free gaming on compatible PCs and consoles.

The G3‘s HDMI 2.1 ports offer the full 48Gbps bandwidth, allowing for 4K gaming at 120fps with 10-bit color and HDR. This makes the G3 fully equipped to handle the latest gaming consoles and high-end gaming PCs.

LG QNED Mini-LED: Balancing Performance and Value

Impressive Brightness and Local Dimming

While the LG QNED Mini-LED TVs can‘t quite match the infinite contrast and perfect blacks of the G3 OLED, they still offer exceptional performance that comes surprisingly close. The Mini-LED backlight in LG‘s QNED TVs allows for much higher peak brightness levels compared to OLED, with some models capable of exceeding 2,000 nits in HDR content. This extra brightness can make HDR content look even more spectacular, particularly in well-lit rooms.

The precise local dimming capabilities of the Mini-LED backlight also enable QNED TVs to achieve impressive contrast ratios, albeit not infinite like OLED. Higher-end QNED models can have over 2,500 local dimming zones, allowing for deep blacks and minimal blooming around bright objects. While there may still be some slight haloing in demanding high-contrast scenes, the overall performance is a significant step up from traditional LED-LCD TVs.

Wide Color Gamut and Viewing Angles

LG‘s QNED TVs also deliver excellent color performance, thanks to the combination of Quantum Dot and NanoCell technologies. High-end QNED models can cover nearly 90% of the DCI-P3 color space and around 70% of Rec. 2020, resulting in vibrant, accurate colors that come close to the performance of the G3 OLED.

The NanoCell technology used in LG‘s QNED TVs helps to improve viewing angles compared to traditional VA-type LED-LCD panels. While not quite as wide as the viewing angles of an OLED TV, QNED models still maintain good color and contrast performance at moderate off-center angles, making them a solid choice for most living room setups.

Gaming Performance and Value

LG‘s QNED TVs are also well-equipped for gaming, with most models offering 120Hz refresh rates, low input lag, and support for VRR and ALLM. Some higher-end QNED TVs even offer full-bandwidth HDMI 2.1 ports, allowing for 4K gaming at 120fps with 10-bit color and HDR.

One of the most appealing aspects of LG‘s QNED lineup is the value they offer compared to OLED TVs. While still positioned as premium TVs, QNED models are generally more affordable than their OLED counterparts, with prices ranging from around $1,000 for a 50-inch model to $3,500 for an 86-inch model. This makes them an attractive option for those who want high-end performance without the premium price tag of an OLED TV.

Considerations and Use Cases

Burn-in Risk on OLED TVs

One potential concern with OLED TVs is the risk of permanent image retention, or "burn-in," which can occur when static elements, such as channel logos or game HUDs, are displayed on the screen for extended periods. While LG has implemented various measures to mitigate this risk, such as pixel shifting and automatic brightness limiting, it‘s still something to keep in mind for those who watch a lot of content with static elements or plan to use the TV as a computer monitor.

QNED TVs, being LED-LCD based, do not suffer from burn-in risk, making them a safer choice for those concerned about this issue. However, it‘s worth noting that significant advancements in OLED technology and pixel refreshing techniques have made burn-in less of a concern for most users in recent years.
