LG B5 Series OLED 4K TV (2025) vs Samsung S90H OLED 4K Smart TV

Both are 48-inch OLEDs with 120Hz-or-better panels and four HDMI 2.1 ports, so the split comes down to brightness, gaming headroom and software. The Samsung S90H pushes a 165Hz VRR panel, a 2.1-channel 40W speaker system and seven years of Tizen updates, which suits gamers and people who keep a TV a long time. The LG B5 counters with Dolby Vision, which the Samsung lacks, plus webOS and strong OLED gaming features. Owners rate the LG well but from a small sample; the Samsung's newer panel and audio setup give it the edge for most buyers.

• Choose the LG B5 if you watch a lot of Dolby Vision movies and shows and want webOS with LG's game dashboard.
• Choose the Samsung S90H if you want the higher 165Hz refresh, better built-in sound and the longest software support.
