Which is better for a bright living room?

The LG G5. Its Brightness Booster Ultimate panel is up to 45% brighter and cuts glare and reflections better than the S90D.

Which is better for gaming?

The LG G5 edges ahead with 165Hz, VRR and ALLM. The Samsung S90D still handles 144Hz gaming well with four HDMI ports on both.

Does the Samsung S90D support Dolby Vision?

No. It supports HDR10+ and HLG. The LG G5 supports Dolby Vision, which matters for Dolby Vision movies and shows.

Both are OLED panels with similar lifespans. The LG's brighter panel may age faster if you run it at maximum brightness for hours daily; either way, avoid static logos at full brightness.

Is the LG G5 worth stepping up to?

Yes for most buyers. The brighter panel, Dolby Vision and flush mount are real upgrades. Step down to the S90D only if you need a 48-inch size or Samsung's ecosystem.

Can I wall mount both?

Yes. The Samsung uses a standard 300x200 VESA bracket and includes a stand. The LG uses its own flush One Wall mount, and the table stand is sold separately.

Samsung S90D 65-Inch OLED TV vs LG 65 Inch OLED evo Smart TV

The LG G5 is the stronger TV: a brighter OLED evo panel, Dolby Vision, 165Hz refresh and a flush wall-mount design. The Samsung S90D is a solid OLED with 144Hz gaming and a wider size range, but it lacks Dolby Vision and its brightness trails the G5. Buy the LG for a bright room, film lovers and wall mounting; buy the Samsung if you want a smaller 48-inch OLED or prefer Samsung's interface and ecosystem.

Choose the Samsung S90D if you want a 48-inch OLED, prefer Samsung's Tizen apps and SmartThings, or already use a Samsung soundbar and phone.
Choose the LG G5 if you watch in a bright room, want Dolby Vision and Dolby Atmos, or plan to hang the TV flush on a wall.
