Which is better for gaming?

The G1. It has a 120Hz panel, four HDMI 2.1 ports, VRR and lower input lag at high frame rates. The A2 caps at 60Hz and HDMI 2.0.

Is the G1 worth stepping up to over the A2?

Yes if you game, watch in a bright room, or want better built-in sound. The evo panel, 120Hz and Alpha 9 chip are real upgrades. For a dim bedroom with movie watching only, the A2 covers the basics.

Which has better picture quality?

The G1. Both are OLED with perfect blacks, but the evo panel is brighter and the Alpha 9 processor handles upscaling and tone mapping better.

Does the G1 come with a stand?

No. The G1 is a gallery TV designed for flush wall mounting, and a stand is sold separately. The A2 includes its stand.

Both use OLED panels with similar lifespan ratings for normal viewing. The G1 is a 2021 model, so it will stop receiving webOS updates sooner than the newer A2.

Do both support Dolby Vision and Atmos?

Yes. Both handle Dolby Vision and Dolby Atmos, though the G1's 60W 4.2-channel speakers deliver more of the Atmos effect.

LG A2 OLED 4K Smart TV vs LG G1 OLED evo Gallery TV

The G1 is the better TV on every spec that matters: a brighter OLED evo panel, 120Hz with HDMI 2.1, the Alpha 9 processor, and a 4.2-channel 60W speaker system. The A2 is a 60Hz OLED with HDMI 2.0 and the entry Alpha 7 chip, so it suits a bedroom or a casual viewer who wants OLED contrast without gaming features. Owners praise OLED black levels on both; reviewers note the A2's dimmer panel and limited gaming headroom, while the G1's gallery design is meant to wall-mount and its stand is sold separately.

Choose the LG A2 if you watch movies and shows in a normal room, don't game at high frame rates, and want OLED picture without paying for features you won't use.
Choose the LG G1 if you game on a console or PC, watch in a bright room, or want the brighter evo panel, 120Hz, HDMI 2.1 and stronger built-in sound.
