Samsung has introduced the 65S99H, a 65-inch QD-Oled television with a 4K resolution (3840 x 2160 pixels) and OLED backlighting technology. This model supports HDR formats such as HDR10, HDR10+, and HLG, and features a 165 Hz panel frequency, making it ideal for gaming. It includes four HDMI 2.1 ports, which support variable refresh rate (VRR) and auto low latency mode (ALLM). The television measures 1509 x 934 x 257 mm and weighs 21.3 kg. Connectivity options include four HDMI ports, two USB ports, Ethernet, S/PDIF optical, and wireless capabilities such as Bluetooth, Wi-Fi, AirPlay 2, and Chromecast. It runs on the Tizen operating system and includes a built-in voice assistant, Bixby. The reparability index is 8.3 out of 10. The 65S99H is praised for its image quality, thanks to its QD-Oled panel, which delivers deep blacks, excellent contrast, and wide viewing angles. In standard dynamic range (SDR) mode, the filmmaker setting offers accurate color representation, even with a Delta E of 2.9 and a warm color temperature of 6084 K, achieving a brightness of 430 cd/m². In HDR mode, the television reaches a peak brightness of 2900 cd/m² on a 10% window, with a Delta E of 1.8, indicating precise color accuracy. It covers 100% of the DCI-P3 color space and 89.1% of Rec.2020. The anti-reflective filter is effective, reducing screen reflectance to 6%. However, some issues remain, such as visible banding on gradients, slightly muted blacks in very bright environments, and the lack of Dolby Vision support. The 65S99H is well-suited for gaming, with four HDMI 2.1 ports that support VRR and ALLM, and a panel that can reach 165 Hz. This is especially beneficial for PC gamers, as most consoles are limited to 120 Hz. The input lag is minimal, measuring 9.4 ms at 60 Hz and 4.9 ms at 120 Hz, with almost no OLED afterimage. The color accuracy remains strong in game mode, with a Delta E of 1.8 in both SDR and HDR using the Original profile. The audio system provides decent sound quality with strong bass, but it lacks impact and dynamic range. Spatial sound is limited to the width of the screen, making a soundbar a better option for a full home cinema setup. In terms of design, the 65S99H is optimized for wall mounting and includes an Art mode for aesthetic integration into a room. However, the One Connect wireless box is optional. The Tizen operating system is feature-rich, while the solar-powered remote is convenient but lacks backlighting and a direct source-changing button. The average power consumption is 74.3 W, or 89.1 W/m², which is relatively high, though still less than many Mini-Led models during HDR content playback. Samsung’s 65S99H is a high-end QD-Oled television that combines excellent performance with a design suitable for wall mounting. Its impressive HDR brightness, accurate colors, wide viewing angles, and effective anti-reflective properties make it one of the most compelling televisions available. Minor issues like occasional banding, less impactful audio, and the optional One Connect box slightly detract from its appeal, but the 65S99H remains one of the best televisions of 2026. The main competitor to the 65S99H is the S95F from 2025, which is currently available for around 1600 € in a 55-inch size, about 1000 € cheaper. If the S95F is unavailable, the S92H from 2026 is a more affordable alternative, though less high-end. Compared to the LG G6, the 65S99H excels in anti-reflective performance, Rec.2020 color coverage, and peak brightness on a 10% window. However, the LG G6 offers Dolby Vision support, better black levels in bright rooms, superior energy efficiency, and a slightly lower price. Compared to Mini-Led and Mini-Led RGB models, the 65S99H is generally considered better, avoiding issues such as blooming and narrow viewing angles. It outperforms models like the TCL C89L and Hisense UR9S, which are cheaper, and its cousin, the R95H, which is priced higher but performs worse in several areas. The Bravia 9 II is a strong competitor, offering unprecedented peak brightness, effective anti-reflective properties, and a more robust audio system.
