LG C5 77-inch OLED evo 4K Smart TV vs LG C5 Series OLED evo 4K Smart TV

Both are LG OLED evo C5 sets with the same Alpha 9 Gen8 processor, so picture quality, webOS, gaming features and build are close to identical. The real split is size: the 77-inch model fits more rooms and walls, while the 83-inch model gives a noticeably bigger image for large, light-controlled living rooms. The 77-inch listing also carries a 144Hz panel claim and a bundled multi-year protection plan, which matters if you game on PC or want longer coverage. Buy the 83-inch only if the room can seat you far enough back to make the extra screen area count.

• Choose the LG 77-inch OLED evo C5 if your room, wall or seating distance suits a 77-inch screen, or if you want the higher 144Hz refresh claim and the bundled protection plan.
• Choose the LG 83-inch OLED evo C5 if you have a large, light-controlled room and sit far enough back that the bigger panel gives a visibly more immersive picture.
