LG C3 77" OLED TV vs LG C5 OLED evo 4K TV

Both are LG OLEDs with perfect blacks, Dolby Vision and Dolby Atmos, so the real split is size versus generation. The C3 is a 77-inch panel, which gives a far more cinematic picture in a large room; the C5 is a 55-inch 2025 set with the brighter OLED evo panel, the newer α9 Gen7 processor and four HDMI 2.1 ports. Reviewers rate the C5's brightness and processing a step above the C3, but no processing upgrade closes a 22-inch gap. Buy the C3 for a big, dark-room theater; buy the C5 for a smaller room where picture quality per inch matters more than size.

• Choose the LG C3 77" if you sit far from the screen or want a big, immersive movie and sports picture in a room you can darken.
• Choose the LG C5 55" if your seating distance is short, you game on a console or PC, or you want the newest panel and processor.
