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.
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. 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. 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. 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. OLED TVs like the LG OLED G3 are self-emissive unlike LCD panels found on other TVs, there's no backlight.
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.
