Which is better for gaming?

The LG. It has a 144Hz panel, 144Hz VRR and AMD FreeSync Premium. The Sony runs at 120Hz and lists no VRR format.

Is the Sony worth the extra money?

Only if you want the 75-inch screen, Sony's XR processing and the bundled soundbar. At $3,398.00 at Macy's versus $629.99 at Walmart as of November 8, 2026, the LG is far better value on picture per dollar.

Which has better sound out of the box?

The Sony, because it ships with the HT-A8000 11-channel soundbar with Dolby Atmos. The LG relies on built-in speakers.

Which is better for a bright room?

Both use Mini LED backlights. The Sony's anti-glare coating and XR Backlight Master Drive give it the edge in very bright rooms; the LG is still bright for the price.

Neither maker publishes a lifespan figure. Both are LED-backlit sets expected to run many years; the Sony's higher build quality and bundled bar may age better, but the LG costs far less to replace.

Do both support Dolby Vision?

Yes. The LG adds HDR10 Pro and FILMMAKER MODE; the Sony lists Dolby Vision and HLG.
