Is the 83-inch worth the extra over the 48-inch?

Only if your room and seating distance call for it. The picture technology is the same, so you are paying almost entirely for size. In a small room the 83-inch is wasted and can look overwhelming.

Which is better for gaming?

Both run 4K at 120 Hz, so motion is similar. The 48-inch is the easier pick for a desk or bedroom setup, while the 83-inch suits a console in a large living room.

Neither has a published lifespan advantage; both are OLED panels with the same burn-in risk from static content. The 48-inch is cheaper to replace if something fails.

How far should I sit from each?

About 6 to 8 feet for the 48-inch and about 10 to 13 feet for the 83-inch. Sitting too close to the 83-inch makes the picture feel oversized.

Do both have the same smart features?

The 48-inch listing confirms webOS, Google Assistant, Wi-Fi, Bluetooth and four HDMI ports. The 83-inch is the same B6 series, so expect the same platform, though its port count is not listed.

Can one person mount the 83-inch?

No. At 83.6 lb it needs two people and a heavy-duty wall mount. The 48-inch at 25.8 lb can be handled by one careful person.

LG 48" Class B6 OLED AI 4K Smart webOS TV with Perfect Black, Vivid Color and Magic Remote (2026) vs LG 83-Inch OLED AI 4K B6 Series Smart TV, 2026 Model

Both are LG B6 OLEDs from 2026 with the same 4K 120 Hz panel technology, so the real choice is screen size against room and budget. The 48-inch fits small rooms and sits around $159 at Distritech as of November 3, while the 83-inch is a flagship-size set that costs several times more. Buy the 48-inch for a bedroom or apartment; buy the 83-inch only if you have a large wall and a big budget.
