LG G3 83" 4K OLED TV vs LG G3 OLED evo 77" 4K TV

Both are LG G3 OLEDs, so the picture technology is the same: OLED panel, 120 Hz, four HDMI 2.1 ports, webOS and the flush wall mount. The 83-inch G3 is the larger screen and is the one to buy if you sit far back or want the biggest cinema image; the 77-inch G3 is the more sensible size for most living rooms and is easier to place. Owners and reviewers consistently praise brightness and picture quality on both, and the G3 line is known for its Brightness Booster and anti-glare coating. Neither is a budget set, and both are best in a room where you can control light.

  • Choose the LG 83" G3 if you have a large wall, sit more than about 9 feet back, and want the biggest OLED image LG makes in this line.
  • Choose the LG 77" G3 if your room or seating distance suits a 77-inch screen and you want the same G3 picture in a size that fits more walls.

What reviewers say

LG G3 83" 4K OLED TV

Owners and reviewers rate the G3 highly for its brightness and picture quality, calling the MLA panel a real step up from earlier OLEDs. Most criticism centers on the missing stand, the size and weight of the 83-inch model, and the usual OLED cautions about burn-in and bright-room reflections.

What people mention
  • BrightnessPraisedOwners say the MLA panel is clearly brighter than earlier OLEDs and holds up in daytime viewing.
  • Picture qualityPraisedReviewers praise the contrast, color and detail, especially with HDR content.
  • StandCriticisedBuyers complain the TV ships without a stand, so wall-mounting or an extra purchase is required.
  • Size and weightMixedThe 83-inch screen is impressive but heavy and needs careful handling and a strong mount.

LG G3 OLED evo 77" 4K TV

Professional reviewers and owners consistently rank the G3 among the best OLED TVs of its generation, praising the brightness jump from the MLA panel and its gaming feature set. Complaints center on the missing stand, reflections in bright rooms, and webOS advertising.

What people mention
  • BrightnessPraisedOwners and reviewers say the MLA panel is clearly brighter than prior LG OLEDs, giving HDR more impact.
  • GamingPraisedFour HDMI 2.1 ports, low lag and VRR support are repeatedly called out as a strong package for consoles.
  • StandCriticisedBuyers note there is no stand in the box, so a wall mount or separate stand is required.
  • ReflectionsCriticisedReviewers report visible reflections when the TV faces windows or bright room lights.

Questions and answers

Which is better for a large living room?
The 83-inch G3 if your seating is far enough back to fill your view. The 77-inch G3 is better if the wall is narrower or seats are closer.
Do they have the same picture quality?
They share the G3 OLED panel, a9 processor and 120 Hz refresh. The 77-inch listing cites Brightness Booster Max, so check the 83-inch spec sheet if peak brightness matters to you.
Which is easier to wall mount?
The 77-inch G3 ships with a flush wall bracket. The 83-inch needs a separate VESA mount and is much heavier, so plan for a stud-mounted install.
Is the bigger screen worth stepping up to?
Only if your room supports it. A larger screen at the wrong distance looks worse than a smaller one placed correctly, and the 83-inch is harder to install.
Which is better for gaming?
Both offer 120 Hz and four HDMI ports, so gaming performance is close. The 77-inch is easier to fit in a game room and comes with the flush mount.
