Is the LG C6 a big step up from the C5?

The C6 adds the Alpha 11 Gen3 processor, a 165Hz panel and higher brightness through Hyper Radiant Color Tech. If you already own a recent C-series set, the jump is modest; from an older OLED or LCD it is a clear upgrade.

Is 165Hz useful for consoles?

Consoles cap at 120Hz, so the extra refresh mainly benefits PC gamers. The TV still supports VRR through G-Sync and FreeSync Premium for smoother console play.

OLED pixels can dim unevenly after long exposure to static elements like news tickers or game HUDs. OLED Care helps manage this, and mixed viewing habits lower the risk.

Does it support Dolby Vision and Atmos?

Yes. It handles Dolby Vision HDR and Dolby Atmos, and includes FILMMAKER MODE for a picture closer to the director's intent.

You get the TV, its stand, a remote and the power cable. A wall mount and cables for external devices are not included.

How bright is it in a sunny room?

Brighter than earlier C-series OLEDs, but it still cannot match high-end Mini-LED LCDs in a very bright room. It performs best with some light control.
