Which is better for gaming, the G4 or the G6?

The G6 has a slight edge. Both run 120Hz native with VRR, ALLM and four HDMI 2.1 ports, but the G6 adds QFT (Quick Frame Transport) and the newer α11 Gen3 processor.

Do both come with a wall mount?

No. The G6 ships with a wall mount kit and lists a 600 x 400 VESA pattern. The G4's listed specs do not include a mount or a VESA pattern, so plan for one separately.

Is the G6 worth stepping up to over the G4?

If you want the newest processor, Bluetooth 5.3, QFT and a bundled mount, yes. If you already have a mount and care about Wi-Fi 6E, the G4 covers the same 97-inch OLED panel and audio.

Which has better connectivity?

They are close. Both have four HDMI 2.1 ports, Bluetooth and smart TV apps. The G4 lists Wi-Fi 6E; the G6 lists Bluetooth 5.3 and QFT but no Wi-Fi standard.

Are the picture and sound the same?

Largely yes. Both are 97-inch 4K OLED panels at 120Hz native with Dolby Vision, HDR10 and HLG, and both use a 60W 4.2-channel speaker system. The G6's Gen3 processor may handle upscaling and tone mapping differently.

Neither has a published lifespan advantage. Both use the same OLED panel class and weigh the same without the stand. The G6 is newer, so it will likely receive smart-platform updates for longer.

LG G4 OLED 97-Inch 4K Smart TV vs LG OLED97G6WUA OLED TV

Both are 97-inch 4K OLEDs with 120Hz panels, four HDMI 2.1 ports and 60W 4.2-channel audio, so the picture experience is close. The G4 is the 2024 G-series set with the α11 processor and Wi-Fi 6E; the G6 is the newer generation with the α11 Gen3 chip, Bluetooth 5.3, QFT support and a wall mount kit in the box. Buy the G6 for the newest processing and a cleaner wall install; buy the G4 if you want the well-documented 2024 flagship and don't need the bundled mount.

Choose the LG G4 if you want the proven 2024 G-series flagship OLED and Wi-Fi 6E, and you already have a mount or stand plan.
Choose the LG G6 if you want the newest α11 Gen3 processor, Bluetooth 5.3, QFT gaming support and a wall mount kit included.
