Is the 65-inch worth $400 more than the 55-inch?

Only if you sit 8 to 10 feet back. At that distance the 65-inch fills more of your view and the extra size is noticeable. Closer than 8 feet, the 55-inch looks sharp and saves you $400.

Do the two TVs have the same picture quality?

Yes. Both use the same 4K OLED panel, Alpha 11 Gen3 processor, 120Hz native refresh and Dolby Vision. The difference is screen size, not image quality.

Which is better for gaming?

They are equal. Both offer 0.1ms response time, 120Hz native refresh, VRR up to 165Hz and four HDMI 2.1 ports. Pick by size and room, not by gaming features.

Neither has a stated lifespan advantage; both are OLED panels with the same design. OLED brightness can fade over many years, and the larger 65-inch has more pixels doing the same job, so treat them as comparable.

Which one is easier to mount?

The 55-inch. It weighs about 31 lb without the stand versus 36.6 lb for the 65-inch, and both use a 300 x 200 VESA pattern on the 55-inch. Check the 65-inch's VESA spec before buying a bracket.

Which has better voice control?

The 65-inch lists Google Assistant, Amazon Alexa and Siri. The 55-inch listing names only Siri, so check the set's menus if you rely on Alexa or Google.

LG C6 Series OLED TV vs LG C6 Series OLED TV

Buy the 55-inch if your seating distance is under about 8 feet or your budget is near $1,000; buy the 65-inch if you sit 8 to 10 feet back and want the bigger image.

Today the LG C6 Series OLED TV costs $400.00 less at its best price.
