Samsung S90H OLED 4K Smart TV vs LG OLED48C4PUA OLED TV

Buy the LG OLED48C4PUA for movies and mixed viewing: it supports Dolby Vision, which the Samsung S90H lacks, and its α9 Gen7 processor and Filmmaker Mode are well regarded by reviewers. Buy the Samsung 48" S90H for gaming and PC use: its 165 Hz panel and four HDMI 2.1 ports beat the LG's 120 Hz, and owners rate it slightly higher. Both are 48-inch OLEDs with perfect blacks and wide viewing angles; the LG C4 is the more established set with a long review record, while the S90H is a newer 2026 model with less track record.

• Choose the Samsung 48" S90H if you game on a PC or console at high frame rates and want the faster 165 Hz panel and Tizen's built-in assistants.
• Choose the LG OLED48C4PUA if you mostly watch films and want Dolby Vision, Filmmaker Mode and the mature webOS 24 platform.
