Samsung 55" S90F OLED 4K TV vs LG C4 OLED evo 4K Smart TV

Both are 55-inch 120 Hz OLED 4K TVs with four HDMI ports, and both are strong picks. The Samsung S90F adds an anti-glare coating and Google Assistant plus Alexa built in, which suits bright rooms and mixed smart-home setups. The LG C4 is the better gaming display: it carries Nvidia G-Sync VRR certification and full HDMI 2.1 features that console and PC players rely on. Owners of both praise the deep blacks and wide viewing angles that OLED gives; the LG has the longer track record with reviewers as the gaming reference, while the Samsung wins on glare handling.

• Choose the Samsung S90F if your room gets daylight glare or you want Google Assistant and Alexa on the TV itself.
• Choose the LG C4 if you game on a PC or console and want certified G-Sync VRR and the established OLED gaming pedigree.
