LG C3 OLED (65-inch) vs Sony Bravia XR X90L (65-inch)

Both sets are 65-inch 4K panels that refresh at 120Hz, so on the basic spec sheet they match. The difference is how light is produced. The C3's OLED evo panel lights each pixel individually, which is why our record lists perfect blacks and infinite contrast, and why viewing angles hold up when people sit off to the side. The X90L uses a full-array LED backlight with local dimming, so black levels depend on how finely that backlight can be divided — our notes flag fewer dimming zones than some mini-LED competitors, and narrower viewing angles than an OLED.

In a dark room the C3's contrast is the part of the picture you notice. In a bright room, the set that can push more light through reflections usually looks more impressive, and our C3 record lists peak brightness below the best mini-LEDs. The X90L also carries Sony's Cognitive Processor XR, which our notes credit with reliable upscaling of lower-resolution content.

The trade-offs show up over time. The C3 carries a burn-in risk with static content such as news tickers and fixed sports logos, and our record also notes a reflective screen in bright rooms. The X90L avoids the burn-in question entirely because it is an LED set, and it runs Google TV — the interface you use every day, which you can replace with an external streamer if you prefer.

For gaming, both claim 120Hz. The C3's advantage is connectivity: four HDMI 2.1 ports with VRR and ALLM, plus Dolby Vision, HDR10 and HLG. That matters if you have a console, a PC and a soundbar all wanting a fast input. Sony's listed strength here is picture processing and upscaling rather than port count.
