Are you in the market for a new LG television but feeling overwhelmed by all the options and jargon? Two of the most common terms you‘ll come across are "4K" and "LED", but what do they actually mean? More importantly, which technology comes out on top in an all-out brawl?
As a digital technology expert and TV aficionado, I‘ve pit LG‘s top 4K and LED models against each other to crown a champion. But first, let‘s define these two TV types and explore how they work.
4K and LED: A Tale of Two Technologies
4K, also known as Ultra HD, refers to the number of pixels that make up the TV‘s display. 4K TVs have a resolution of 3840 x 2160, which equates to over 8 million pixels. That‘s four times the resolution of 1080p HD TVs, resulting in incredibly sharp and detailed pictures.
4K content has become increasingly common, with streaming services like Netflix, Amazon, and Disney+ offering expansive libraries of 4K titles. Gaming consoles such as the PS5 and Xbox Series X also output in 4K, as do many modern cameras and smartphones. If you want the best possible picture quality, 4K is the way to go.
LED, on the other hand, actually refers to the backlighting technology, not the display itself. LED TVs still use LCD panels, but they employ light-emitting diodes to illuminate the picture rather than older cold-cathode fluorescent lamps (CCFLs).
The main advantage of LED backlighting is improved energy efficiency – up to 30% less power consumption compared to CCFL LCDs. LEDs also enable much thinner TV designs since the diodes are smaller than fluorescent tubes.
There are three main types of LED arrangements in TVs:
-
Edge-lit: The most common type, edge-lit TVs have LEDs positioned along the edges of the screen. This allows for extremely slim profiles but less precise local dimming.
-
Direct-lit: LEDs are arranged behind the entire LCD panel, providing more uniform brightness and better local dimming than edge-lit. However, direct-lit TVs tend to be thicker.
-
Full-array: Like direct-lit but with even more LEDs and granular local dimming zones. Considered the best LED TV arrangement for contrast and HDR performance.
Most of LG‘s LED models use edge or direct backlighting, while their higher-end LCD TVs feature full-array with local dimming (FALD). It‘s worth noting that some manufacturers use "LED TV" as a marketing term for all LCD TVs now, since CCFL LCDs are basically extinct.
LG 4K vs LED: Clash of the Specs
Now that we‘ve covered the basics of 4K and LED tech, let‘s see how LG‘s offerings stack up in key areas like price, picture quality, feature set, and more.

As you can see, LG‘s 4K models have a clear edge in most areas, especially when it comes to HDR performance, contrast, viewing angles, and gaming features. However, they also cost significantly more than LG‘s entry-level LED TVs.
OLED vs QNED vs LED: Panel Wars
One of the biggest factors in picture quality is the type of display panel used. LG offers three main panel technologies in their current lineup:
-
OLED: LG‘s flagship self-emissive panel, each pixel produces its own light and color. This allows for perfect black levels, infinite contrast, wide viewing angles, and excellent response times. However, OLEDs are expensive and not as bright as LED LCDs.
-
QNED Mini LED: New for 2021/2022, LG‘s QNED series combines quantum dot color with Mini LED full-array backlighting. This enables much finer local dimming, higher peak brightness (up to 2,000 nits), and better off-axis viewing than traditional QLEDs.
-
NanoCell LED LCD: LG‘s mid-range LED LCDs feature a proprietary NanoCell layer that absorbs unwanted wavelengths and enhances color purity. Combined with full-array local dimming, these provide very good picture quality for the price.
For the best possible movie watching experience, LG‘s OLED models like the C2 and G2 are unmatched. Videophiles love the perfect blacks, precise highlights, and realistic colors. However, they struggle in very bright rooms and are susceptible to burn-in if you constantly watch the same content with static elements.
If you need something brighter for daytime viewing or want to avoid burn-in risk, LG‘s QNED Mini LEDs offer exceptional peak brightness and local dimming while still covering nearly 100% of the DCI-P3 color space. They‘re not cheap, but provide arguably the best LCD picture available.
LG‘s standard NanoCell and UHD models are great budget-friendly options that still deliver bold colors and decent local dimming. They won‘t get as bright or offer as wide viewing angles as QNED, but most people will be very happy with the picture, especially in sub-65" sizes.
Sizing Up the Competition
When deciding between 4K and LED, screen size is an important factor to consider. To fully appreciate 4K‘s higher pixel density, you need to sit closer to larger screens than you would with 1080p sets. Here‘s a quick guide:
| Screen Size | Recommended Viewing Distance for 4K |
|---|---|
| 40-43" | 3-5 feet |
| 50-55" | 4-7 feet |
| 60-65" | 5-8 feet |
| 70-75" | 6-9 feet |
| 80-85" | 6.5-10 feet |
LG‘s 4K OLED lineup starts at 42" and goes up to a massive 97", while their 8K models reach a whopping 98". That‘s far beyond the size needed to discern 4K and 8K resolution benefits. In other words, don‘t buy a 48" OLED or 43" UHD if you sit 10 feet away, stick with a larger LED model.
On the flip side, 24-43" LG LED models are great for bedrooms, dorms, offices, and other small spaces where you‘ll be sitting close to the TV. You likely won‘t notice the resolution difference versus a same-size 4K set, and the LED TVs are far cheaper.
Smarten Up Your Home Theater
LG‘s 4K and LED models both offer robust smart TV platforms and voice control options. The newest webOS 22 graces the company‘s high-end OLED, QNED and NanoCell series, while the more affordable UQ75 use webOS 6.0. LG‘s entry LED TVs pack basic smart features in their webOS 5.0 or 22 platforms.
WebOS is known for its user-friendly layout, quick navigation, and extensive app support. You get all the major streaming services like Netflix, Prime Video, Disney+, Apple TV+, and HBO Max. LG also has an excellent selection of free channels through its LG Channels service, just watch out for the ads.
LG‘s ThinQ AI technology allows you to control your TV and other compatible smart home devices using natural language voice commands. It leverages Google Assistant and Amazon Alexa to provide a seamless experience, whether you‘re searching for content, checking the weather, or dimming your smart lights.
LG‘s Magic Remote is another handy feature, letting you point, click, and scroll your way through menus like a computer mouse. Some 4K models like the C2 OLED and QNED90 also offer far-field microphones in the TV for hands-free voice control, even when the screen is off.
One area where LG‘s LED models have a slight edge is in automatic content detection and optimization. The newest webOS 22 uses AI to automatically switch between game and movie modes depending on the input signal, ensuring the best possible picture and lowest latency without you having to fumble through settings.
Next-Gen Gaming Chops
If you managed to snag a PS5 or Xbox Series X, you‘ll definitely want a TV that can take full advantage of their next-gen features. LG‘s 2021 and 2022 4K lineups are well-equipped in this regard, thanks to HDMI 2.1 inputs with 4K@120Hz, VRR (variable refresh rate), and ALLM (auto low latency mode) support.
In particular, the LG C1 and C2 OLEDs have become go-to picks for many gamers due to their near-instantaneous response times, low input lag, deep blacks, and vibrant colors. The QNED Mini LED series is a great LCD alternative with higher peak brightness and no burn-in risk.
Unfortunately, LG‘s entry-level LED models lack any HDMI 2.1 features, so you‘ll be limited to 4K@60Hz, with no VRR or ALLM. They‘re fine for casual gaming, but if you want the smoothest, most responsive experience, opt for a mid-range NanoCell or splurge on the OLED or QNED.
Frequently Asked Questions (FAQ)
Q: What does 4K actually mean?
