Skip both if

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

The LG OLED77C2PUA and the Samsung QN77Q90TAFXZA represent two distinct approaches to large-screen 4K television performance. The LG OLED77C2PUA relies on a confirmed OLED panel that delivers the deep blacks, wide viewing angles. And support for Dolby Vision HDR expected from the format, along with established street pricing that makes its value straightforward to assess. In contrast, the Samsung QN77Q90TAFXZA positions itself as a premium LCD option whose exact panel configuration, peak brightness, and feature set remain partially undisclosed in current public materials. Both models list incomplete specifications around HDMI 2.1 port counts, variable refresh rate support, and auto low latency mode, leaving some performance questions open until full retail documentation appears. Public reviews of the LG model consistently highlight its contrast accuracy. And motion handling, while early Samsung commentary focuses on anticipated color volume and upscaling strengths without final confirmation. The short version: choose the LG OLED77C2PUA for immediate, well-documented 77-inch OLED capability and pricing certainty rather than waiting on the Samsung QN77Q90TAFXZA.

Verdict: Pick LG OLED77C2PUA if you need confirmed 77‑inch 4K OLED performance with Dolby Vision and known pricing. Pick QN77Q90TAFXZA only if you can wait for official specs and pricing. Neither publishes peak brightness, HDMI 2.1 ports or VRR / ALLM yet.
