LG G3 OLED 77": Peak brightness, HDMI 2.1 ports, VRR / ALLM. No manufacturer, official or retailer source we read publishes these yet; we don't estimate them.

Skip both if

Neither publishes peak brightness, HDMI 2.1 ports or VRR / ALLM yet.

The Sony Bravia XR-75Z9K and the LG G3 OLED 77 inch present two distinct approaches to large-screen premium television performance according to aggregated public specifications and reviewer data. The Sony Bravia XR-75Z9K relies on a Mini LED backlight with Cognitive Processor XR for brightness. And local dimming control, while the LG G3 OLED 77 inch uses a self-emissive OLED panel paired with the Alpha 9 Gen 6 processor and Brightness Booster Max technology. Public listings confirm the LG model delivers a native 120 Hz refresh rate, four HDMI 2.1 ports, and consistent pricing across major retailers, whereas detailed specifications for the Sony Bravia XR-75Z9K remain sparse outside of select overseas announcements. The short version: choose the LG G3 OLED 77 inch unless verified Sony specifications become available.

Verdict: Pick LG G3 OLED 77" if you want confirmed OLED panel, 120Hz refresh and known price. Pick Sony Bravia XR-75Z9K only if you can locate its specs elsewhere; otherwise skip both due to lack of published data.

Provisional pick: LG G3 OLED 77" — not enough sourced decision facts for Sony Bravia XR-75Z9K. We don't rank on specs we can't verify.
