Which is better for movies?

The Samsung S95F. Its OLED panel gives true blacks and strong contrast, and reviewers rate its picture at the top of what they have tested. The LG NU71 trades that for size.

Which is better for gaming?

The Samsung. It has a 120Hz panel, 165Hz VRR support, HDMI 2.1, ALLM, FreeSync and G-Sync. The LG is 60Hz with no listed VRR features.

Which is better in a bright room?

The Samsung's anti-glare coating and high brightness handle reflections better. The LG's larger screen helps if you sit far away, but its panel is dimmer and more prone to glare.

Is the Samsung worth stepping up to over the LG?

If picture quality and gaming matter, yes. The S95F is a different class of display. Step to the LG only if an 85-inch screen is the priority and you accept entry-level image quality.

Neither maker publishes a lifespan figure. OLED pixels can dim over many years of heavy use, while LED backlights age slowly. Panel defects, not age, are what a few S95F owners report.

Do I need a soundbar with either?

The Samsung's built-in sound is criticized at high volume, so a soundbar helps. The LG's AI Sound Pro is fine for casual viewing but also benefits from a bar for movies.

Samsung S95F QD-OLED TV vs LG NU71 85" Nano UHD 4K Smart TV

These are not close rivals. The Samsung S95F is a 65-inch QD-OLED built for picture quality: perfect blacks, high brightness, an anti-glare screen and 165Hz gaming. The LG NU71 is an 85-inch entry-level Nano LED with 60Hz and basic HDR. Buy the Samsung if the best image matters most; buy the LG if you want the biggest screen for a bright, casual room. Reviewers rate the S95F's picture at the top of what they have tested, though several note weak built-in sound and a few report panel coating or back panel defects.

Choose the Samsung S95F if you sit close, watch movies and games in a dark or mixed room, and want the best contrast, color and motion a TV at this level offers.
Choose the LG NU71 if you sit far back, want the largest screen for a family or bright room, and picture quality is secondary to size.
