Samsung QN90B 75: Screen size, Panel, Resolution, Refresh rate, HDR, Peak brightness, HDMI 2.1 ports, VRR / ALLM, Smart platform, Starting MSRP. 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 LG OLED77C2PUA and the Samsung QN90B 75-inch television represent two distinct approaches to large-screen premium display technology. Public specifications show the LG model relying on its OLED panel to deliver perfect blacks. And infinite contrast alongside confirmed 120 Hz refresh rates that support consistent high-frame-rate gaming and motion clarity. Review aggregates highlight its accurate factory color tuning and reliable HDMI 2.1 implementation. In contrast, the Samsung QN90B 75-inch uses a Mini-LED backlight on a VA panel to achieve high peak brightness. And strong anti-glare performance, yet independent test data on its exact refresh-rate behavior and input lag remain less comprehensive. Both sets earn praise for their smart-platform responsiveness and overall build quality, though the LG carries a published price of $2,799.99 while the Samsung’s street pricing and full technical disclosures have been harder to pin down in early coverage. Bottom line: choose the LG OLED77C2PUA for documented 120 Hz performance. And true OLED contrast at a known price, or opt for the Samsung QN90B 75-inch if brand familiarity outweighs the current gaps in published specifications.
Verdict: If you primarily watch movies or game in a dim environment, the LG OLED77C2PUA wins with its infinite contrast and Dolby Vision support.
