LG C5 OLED TV vs Samsung S90F OLED 4K TV

Both are 2025 4K OLEDs with 120Hz panels, HDMI 2.1 and Dolby Vision, so the picture is close. The LG C5 has four HDMI 2.1 ports, a 144Hz VRR mode for PC gaming, and a long track record of praise for brightness and color; reviewers also flag buggy early software, forced ads and a remote cursor that misbehaves. The Samsung S90F is the simpler, cleaner pick for most living rooms, but it gives up a port and the 144Hz mode. Buy the C5 for a gaming PC or a console plus soundbar setup; buy the S90F for straightforward movie and streaming use.

• Choose the LG C5 if you game on a PC or want four HDMI 2.1 inputs and the smoother 144Hz VRR mode.
• Choose the Samsung S90F if you want a fuss-free OLED for movies and streaming and don't need four full-bandwidth ports.
