Which is better for gaming?

The C6. It adds VRR up to 165Hz, a 0.1ms response time, G-Sync and FreeSync Premium support, and the same four HDMI 2.1 ports. The C4 is a solid 120Hz gaming set but has fewer gaming extras.

Is the C6 worth stepping up to over the C4?

If you want the newer processor, webOS 26 and faster VRR, yes. If you mainly watch movies and want the larger 65-inch screen, the C4 is the better fit.

Which has better picture quality?

Both use self-lit OLED pixels with perfect black and Dolby Vision. The C6's Alpha 11 Gen3 chip and Brightness Booster give it an edge in upscaling and bright-room punch; the C4 still delivers 100% Color Volume and accurate color.

Both are OLED panels with similar expected lifespans, and LG covers burn-in risk with pixel-shifting and logo dimming on both. The C6's newer panel and processor are likely to stay current longer.

Do both support Dolby Vision and Dolby Atmos?

Yes. Both support Dolby Vision, HDR10, HLG and Dolby Atmos. The C6 has a 40W 2.2-channel speaker system, while the C4 uses two speakers.

Which is better in a bright room?

The C6. Its Brightness Booster and newer processor handle reflections and daylight better. Neither OLED matches a bright mini-LED set at midday, so curtains still help.

LG C6 Series OLED TV vs LG OLED evo C4 65-Inch 4K Smart TV

The C6 is the newer, brighter, faster set: Alpha 11 Gen3 processing, VRR up to 165Hz, four full HDMI 2.1 ports and the newer webOS 26. The C4 is a 2024 model with the Alpha 9 Gen7 chip and webOS 24, and the 65-inch size is the main reason to pick it. Buyers rate both highly; the C6 edges ahead on gaming and future-proofing, the C4 on screen area for the same room.

Choose the LG C6 if you sit close, game on a PC or console, or want the latest processor and webOS version.
Choose the LG C4 if you want a 65-inch OLED and the extra size matters more than the newest chip and 165Hz VRR.
