Verified Confidence: 86%

The LG C4 OLED 55 and the Samsung S90D OLED 55 deliver comparable QD-OLED and WOLED panels that produce deep blacks, wide viewing angles. And accurate color reproduction according to aggregated reviewer measurements and manufacturer specifications. Public reports highlight the LG model's support for Dolby Vision HDR alongside a chassis that weighs noticeably less, easing wall-mount installation, while the Samsung version carries a current street price of $1,199. And includes FreeSync Premium compatibility that aligns with variable-refresh-rate gaming setups. Both sets omit official peak-brightness figures and full HDMI 2.1 bandwidth disclosures in their spec sheets, leaving exact performance margins dependent on forthcoming calibration data. The short version: choose the LG C4 OLED 55 for Dolby Vision. And lighter handling or the Samsung S90D OLED 55 for the lower price and gaming sync features.

Verdict: LG C4 OLED counters with Dolby Vision support and more versatile HDMI ports, suiting movie enthusiasts. Both are 2024 models now outdated versus 2025 LG C5 and Samsung S95F.
