LG OLED B46 55" 4K Smart TV vs Sansui S55VOUG 55" OLED TV

Both are 55-inch 4K OLED sets with 120 Hz panels and four HDMI ports, so picture fundamentals are close. The LG B46 is the safer pick: LG makes the OLED panels and its webOS platform, processing and long-term firmware support are well established, and owners consistently praise its contrast and gaming features. The Sansui S55VOUG counters with Dolby Vision, Dolby Atmos, two HDMI 2.1 ports and a 2.1-channel subwoofer built in, which is more hardware for the money. Buy the LG for proven software and panel pedigree; buy the Sansui if you want the extra audio and HDMI 2.1 spec on a tighter budget and accept a less-known brand with thinner support history.

• Choose the LG B46 if you want a mainstream brand with mature smart software, strong gaming features and a long track record on OLED reliability.
• Choose the Sansui S55VOUG if you want Dolby Vision, Dolby Atmos and built-in bass plus two HDMI 2.1 ports in a slim frameless design.
