The LG G3 OLED is a high-end TV in LG's 2023 OLED lineup, sitting above the typically more popular 'C' series LG C3 OLED and the entry-level OLED 'B' series LG B3 OLED, but below the 8k LG Z3 OLED. OLED TVs like the LG OLED G3 are self-emissive; unlike LCD panels found on other TVs, there's no backlight. Instead, an OLED's pixels can change their brightness levels individually and independently of the other pixels, allowing them to display nearly-perfect contrast, with deep inky blacks and no distracting blooming or haloing around bright objects. Like the LG G2 OLED, this TV doesn't come with a stand and is meant to be wall-mounted with the included slim wall mount.
LG promises a 70% brighter image on the G3 over the LG B3 OLED due to the G3's new Micro Lens Array (MLA) technology. The 83-inch variant of the LG OLED G3 doesn't have MLA, so it's promised to be 'only' 30% brighter than the LG B3. The TV comes with the 2023 version of LG's proprietary webOS smart interface and has four full HDMI 2.1 bandwidth ports, which supports every gaming technology you can think of in 2023. It also has LG's latest 2023 processor, the α9 AI Processor Gen6, which promises improved image processing through LG's Brightness Booster Max and AI Tech technologies, as well as the ability to up-mix 2-channel audio into virtual 7.1.2 channel sound using AI Sound. The TV's 4.2 integrated speaker setup, which uses the TV's Dolby Atmos spatial sound technology, complements this.

Differences Between Sizes And Variants
We tested the 65-inch LG G3 OLED (OLED65G3), but it's also available in 55, 77, and 83-inch sizes. The 83-inch model doesn't have the MLA focusing layer, so it isn't as bright as the smaller models. Note that the last three letters in the model number (PUA in this case) vary between retailers and individual regions, but there's no difference in performance.
| Size | US Model | UK Model |
|---|---|---|
| 55" | OLED55G3PUA | OLED55G36LA |
| 65" | OLED65G3PUA | OLED65G36LA |
| 77" | OLED77G3PUA | OLED77G36LA |
| 83" | OLED83G3PUA | OLED83G36LA |
Our unit was manufactured in March 2023; you can see the label here.
Popular TV Comparisons
The LG G3 is an incredible OLED TV with exceptional picture quality and is a big improvement over the LG G2 OLED. Its MLA focusing layer allows it to get extremely bright, and its whites get even brighter than the Samsung S95C OLED, although the latter has the edge regarding bright colors. Unlike past years, there's a large performance gap between the LG OLED G3 and LG's mid-range TV, the LG C3, so we can't as easily recommend that you just get the 'C' series TV as we did in 2022. You'll pay a premium for this TV but get premium performance. It sits alongside the Samsung S95C OLED and the Sony A95L OLED as one of the best TVs you can buy in 2023.

The LG G5 OLED is better than the LG G3 OLED. The G5 is brighter in HDR—especially in Game Optimizer mode—resulting in a more vibrant HDR presentation. It's also much brighter in SDR, and its colors are more vivid. Both TVs are superb for gamers, but the G5 supports up to 165 Hz at 4K, whereas the G3 tops out at 120 Hz. One advantage of the G3 is that it passes through DTS audio formats, which LG dropped from its 2025 models. Overall, the LG G5 is clearly superior.
The LG G3 OLED and LG C5 OLED perform very similarly. The older G3 is a tad brighter in HDR, but the C5 is a bit brighter in SDR. Otherwise, the two sets are almost identical, although the C5 can game at up to 144Hz at 4k, while the G3 is limited to 120Hz. The G3 also passes through DTS audio formats, while the C5 doesn't.
The LG G4 OLED and the LG G3 OLED are very similar TVs overall, but the G4 is a bit better. The G4 gets brighter in HDR, so highlights stand out more on it, and it also maintains its brightness much better in Game Mode, so you don't have to trade in performance if you don't want a decrease in brightness. On top of that, the G4 has better HDR native gradient handling, so there is less banding in colors, and it supports 144Hz, so it's better for PC gamers looking to take advantage of their high-end graphics cards.
The LG G3 OLED is better than the LG C3 OLED. They're both nearly identical, except that the G3 doesn't come with a stand, instead having a slim wall mount included in the box and a fully flat profile that allows the TV to be completely flat on the wall when wall mounted. In theory, the G3 can also get much brighter than the C3; however, in practice, you won't see much difference except in certain contexts, such as when bright white clouds are displayed. They both offer DTS audio support, which is a clear improvement over both preceding models.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
