LG C3 Series OLED evo 4K TV vs Samsung QN77S90F OLED TV

Both are 77-inch 4K OLEDs with 120Hz panels, so the picture quality gap is small. The LG C3 runs webOS with four full-bandwidth HDMI 2.1 ports and Dolby Vision, which suits movie watchers and mixed console use. The Samsung S90F uses a QD-OLED panel with higher color brightness and reaches 144Hz, which suits bright rooms and PC gamers. Owners of both praise deep blacks and wide viewing angles; the LG has the longer track record for burn-in resistance and the Samsung draws more complaints about its stand and Tizen ads.

• Choose the LG C3 if you watch Dolby Vision movies, want four HDMI 2.1 ports for a console plus a soundbar, and prefer webOS over Tizen.
• Choose the Samsung S90F if you game on a PC at 144Hz, watch in a bright room, and want the punchier QD-OLED color.
