The LG G4 OLED TV is only the second TV I’ve thoroughly tested this year, but I already have no doubt that it is a finalist for the top TV spot in 2024. After all the comparisons and tests are complete, I wouldn’t be surprised if the LG G4 emerges as the victor. Nevertheless, it’s already a triumph, representing a significant accomplishment for LG.

When you finish reading this assessment, you will see precisely what I mean. It shouldn’t astonish many of you that the LG G4 is an exquisite piece of technology. It boasts an incredibly thin profile and an almost invisible metallic border — all of it aesthetically pleasing and expertly crafted, including its new tabletop stand.

This year, the 55- and 65-inch models come with that tabletop stand included, a change in strategy due to LG’s attentiveness to customer input. However, the 77-, 83-, and 97-inch models still come with LG’s custom Slim Wall mount in the package for a nearly seamless installation.

LG also offers the OLED M wireless series with a comparable build. Yet, I usually view the Gallery series (the G4 in 2024) as LG’s flagship. As LG’s premier TV, the G4 incorporates top-notch components. It features LG’s OLED evo technology, with a Micro Lens Array panel — a blend of software and hardware that produces the brightest, most vibrant OLED display available. It comes equipped with four HDMI 2.1 inputs, supporting up to 4K 120Hz input signals with variable refresh rate, AMD FreeSync, and Nvidia G-Sync certifications. There’s LG’s gaming dashboard, HGIG (HDR Gaming Interest Group) with less than 1-millisecond input lag time, and the list of technological acronyms goes on. It includes nearly everything you could desire, and then some. The only missing feature is an ATSC 3.0 tuner — a minor flaw that doesn’t diminish its overall excellence.

Perhaps the most crucial element is the heart of the LG G4 operation — LG’s Alpha 11 AI processor. We’ll delve into that shortly.

The minor concerns

There are only a few aspects of the LG G4 that don’t entirely captivate me. Maybe three. Primarily, these are subjective viewpoints. Let’s address these points so we can continue the review.

One issue is LG’s webOS operating system. It’s not a subpar user interface by any means. I respect that the advertisements shown are solely for watchable content, rather than general product ads. However, I’m not enamored with webOS as an operating system. It’s the minor details, such as the streaming apps section having the smallest tiles on the page. I believe they should be more prominent because they’re the most essential feature on the page.

While I appreciate the frequent updates that keep the OS smooth and the apps up to date, the constant app updates can be overwhelming, requiring approval before watching anything.

I’ve also grown weary of the Magic Remote. I understand it sets LG apart and functions as a quasi universal remote control in today’s market. However, it’s not my cup of tea.

Lastly, the sound quality of the TV, although impressive in many aspects, can be vexing. Using LG’s AI Sound Pro feature is the best choice available. However, with the default audio modes, the dialogue is often too low compared to other sounds and occasionally difficult to understand. While the audio offers immerse surround effects and bass, the fidelity is lacking. It can be decent, but surprisingly, the much cheaper Hisense U8N sounds better to me. If you invest in such a high-quality TV, you expect excellent sound quality at all times.

However, I can overlook these points when considering the LG G4. I usually connect an Apple TV box to my TVs and frequently use a soundbar. Even if I have to use the LG Magic Remote, I wouldn’t want to miss out on the exceptional picture quality. The great picture quality of the LG G4 makes any slight inconveniences worth it. The TV is truly a work of art in terms of engineering.

Arguably unbeatable

With all things considered, it’s undeniable that the LG G4 OLED TV justifies its price due to its picture quality alone. The G4 stands as LG’s finest TV to date, and I am leaning towards declaring it the TV with the best picture quality I’ve encountered.

While I’ve bestowed similar accolades on the Sony A95L OLED TV, I won’t finalize my comparison between the LG G4 and the A95L until I’ve thoroughly tested both models.

Yet, I lean towards praising the LG G4 for its unmatched picture quality because it excels in ways the Sony A95L does not. Depending on your preferences, you may prefer the G4 over the A95L for its exceptional picture quality.

The brightness measurements don’t accurately represent the G4’s capabilities.

For those concerned with specifics, the brightness measurements of the LG G4 tell an incomplete story. The Alpha 11 AI processor, responsible for determining the TV’s brightness based on real content, renders the peak brightness measurements irrelevant. Focus on color accuracy, color gamut, and white balance, all of which are outstanding. However, the peak white measurements won’t reveal the TV’s true brightness capabilities.

In standard SDR Filmmaker Mode, the peak brightness from a 10% window ranged from 361 nits (after turning off the eco setting) to 650 nits depending on the settings or picture mode. The two-point white balance was exemplary, with Delta E around 1 for 30% and 100% stimulus. Even at maximum brightness, it remains under 2, which is exceptional.

The grayscale performance out of the box is near perfection, with superb color primary accuracy without calibration.

We observed no errors over a Delta E of 2, and anything below 3 is imperceptible to the human eye. Particularly remarkable was the low luminance color performance, an issue in previous models that LG seems to have resolved successfully.

In HDR content, grayscale tracking excelled, aligning perfectly with the electro-optical transfer function (EOTF). The color temperature remained consistent at peak brightness, an outstanding achievement.

The peak brightness measurements don’t truly reflect the G4’s brightness.

Peak brightness, while impressive, isn’t the most critical aspect in assessing the LG G4. It topped out at 1500 nits on various window sizes up to 10% and 235 nits at full screen. What’s crucial to understand is that the G4 is the brightest OLED TV available, significantly outperforming its competitors.

Color accuracy was flawless, even with minimal luminance discrepancies, positioning it as a nearly reference-grade display.

The TV offers 97.5% DCI P3 and 73% BT.2020 UV, areas where WRGB OLEDs slightly lag behind QD-OLED. However, the limited content utilizing BT.2020 color coverage diminishes its significance.

Prior to concluding the detailed analysis, it’s important to acknowledge why brightness measurements don’t fully capture the G4’s brilliance.

The novel processor and processing capabilities of this TV include pixel-level picture analysis, allowing the Alpha 11 AI processor to make brightness decisions at each pixel level, contributing to an overall higher average picture level without compromising bright highlight details, unlike traditional zone-based approaches. This, paired with LG’s brightness booster max and manual tone mapping adjustments, provides a versatile HDR experience tailored to individual preferences, resolving common issues with dark HDR content. The TV maintains impressive brightness levels, surpassing any OLED TV tested to date.

It’s essential to note that this processing sophistication is only activated during actual content viewing, not during traditional testing scenarios.

The highlights…

The LG G4 OLED not only outperforms last year’s G3 OLED but also stands as the most advanced and versatile OLED TV available. The G4 is a significant leap forward, delivering more revolutionary features than evolutionary changes this year.

The LG G4’s remarkable aesthetics and capabilities justify its price.

Furthermore, LG offers a five-year warranty for the G4, including burn-in protection, easing concerns regarding the TV’s intense brightness potentially causing issues. This warranty demonstrates LG’s confidence in the product, instilling confidence in the prospective owner.

LG deserves recognition for progressively improving its processing capabilities year after year, coming closer to Sony’s industry-leading processing. This year marks a turning point, with LG’s processing now on par with Sony’s. The motion, clarity, color, and exquisite detail featured in the G4 set a new standard in TV processing.
