LG G6 OLED TV vs LG C5 77-Inch OLED TV

Both are LG OLED evo 4K sets with 120 Hz panels and webOS, so the picture fundamentals are close. The G6 is the brighter, more glare-resistant flagship with a flush wall-mount design and the newer a9 Gen8 processor; the C5 is the long-running value line that most people buy. Buy the G6 if the TV goes in a bright room or on a wall where you want it flat and reflection-free. Buy the C5 if you want a big 77-inch OLED and don't need the extra brightness or gallery styling.

  • Choose the LG G6 if you have a bright room, want the lowest reflections, and plan to wall-mount it flush.
  • Choose the LG C5 if you want a large 77-inch OLED and the flagship extras aren't worth the step up to you.

Prices

  • LG G6 OLED TV: $1,999.99 at ABC Warehouse (checked today)
  • LG C5 77-Inch OLED TV: $1,949.64 at Best Buy (last seen Nov 12)

Questions and answers

Which is better in a bright room?
The G6. Its Brightness Booster panel and Reflection Free Premium coating hold up better against windows and lamps than the C5's standard OLED finish.
Is the G6 worth stepping up to over the C5?
If you wall-mount in a bright room, yes. You get more brightness, less glare, a flush mount in the box and the newer processor. In a dark room the gap narrows.
Which has better sound?
The C5 lists Dolby Atmos support; the G6 specs don't. Either way, a soundbar beats both for movies.
Do both support Dolby Vision?
The C5 lists Dolby Vision. LG's own G6 materials list HDR10 and HLG, while the Best Buy spec sheet adds Dolby Vision, so confirm on the exact model before buying.
Which is better for gaming?
Both run 120 Hz OLED panels with VRR. The G6 gives you four HDMI ports and the newer processor, which helps if you connect several consoles.
Which lasts longer?
Both are OLED and share the same panel wear characteristics. The G6's newer processor and coating are the practical differences, not lifespan.
