Design & Build Quality

• LG G5: Gallery-style chassis for flush wall-mounting, tidy cable routing, and four 48 Gbps HDMI that simplify multi-device setups.
• Samsung S95F: Sleek pedestal-friendly design and that matte QD-OLED surface which tames reflections—ideal if you have windows or bright lamps near the screen.
• Panasonic Z95B: Purposeful, slightly more substantial body—by design—for ThermalFlow airflow; cinema-centric tuning with a robust, Technics-influenced speaker array in some regions. ✨

Panel Technology Explained

Primary RGB Tandem (LG G5 & Panasonic Z95B)

A four-emitter OLED stack boosts luminous efficiency and color purity vs older WOLED designs. At 65″, both G5 and Z95B use Primary RGB Tandem; Z95B pairs it with ThermalFlow to keep output stable in long HDR scenes. Result: bright, controlled highlights and unusually strong sustained luminance for real content. 🧠

QD-OLED (Samsung S95F)

Blue OLED emitters + quantum dots yield pure RGB subpixels (no white subpixel), helping bright colors stay saturated at high nits. The matte finish slashes mirror-like reflections and keeps perceived contrast alive in daylight; the trade-off is no Dolby Vision (HDR10/HDR10+ instead).

Brightness & HDR Performance (65″, rounded values)

• LG G5: ~2,450 nits (10% HDR) and ~800 nits SDR real-scene in accurate modes. Highlights are punchy yet controlled; sustain is excellent—great for HDR films and mixed-light viewing. Dolby Vision keeps streaming and UHD Blu-ray consistent. ✨
• Samsung S95F: ~2,100 nits (10% HDR) and ~700 nits SDR real-scene. QD-OLED color luminance plus matte anti-glare yields confident daytime HDR. You’ll rely on HDR10/HDR10+ (no DV).
• Panasonic Z95B: ~2,400 nits (10% HDR) and ~500 nits SDR real-scene in calibrated profiles. ThermalFlow helps maintain output; tone-mapping is restrained and near-black is nuanced. DV + HDR10+ offers format flexibility. 🎬

Color Accuracy & Picture Processing

• Z95B ships reference-leaning (Filmmaker/Professional). Gradations are clean; HDR tracking is conservative rather than showy.
• G5 in Filmmaker/Cinema is easy to dial in; Dynamic Tone Mapping can add pop if you prefer it.
• S95F balances improved Filmmaker/Movie accuracy with QD-OLED’s inherently vivid color volume; the matte surface keeps reflections at bay by day.

Motion Handling & Refresh Rates

All three are 120 Hz native with ultra-fast pixel response. For PC/competitive play: G5/S95F reach 165 Hz, Z95B reaches 144 Hz (availability depends on resolution/port). For films, keep interpolation low to avoid soap-opera artifacts. ⚽

Gaming Performance

• LG G5: 4× HDMI 2.1 (48 Gbps), 4K165, full VRR (HDMI Forum + vendor variants), Game Optimizer, and a clean HGIG workflow. Step-by-step: HGIG gaming settings for PS5/Xbox. 🎮
• Samsung S95F: 4K165, ultra-low input lag, Gaming Hub, and broad VRR. Lack of Dolby Vision Gaming is the main omission; HDR10/HDR10+ are tuned well.
• Panasonic Z95B: 4K144 with 2× HDMI 2.1, True Game mode tuned for accuracy, low lag, clean gradations—ideal for story-driven titles.

Smart Platform & UX

• webOS (G5): fast app access, Game Optimizer overlay, clear picture controls.
• Tizen (S95F): huge app library and Gaming Hub; menus are deeper/denser in places.
• Fire TV / My Home Screen (Z95B, region-dependent): app-rich and clean; you may want to minimize ad surfaces in settings.

Audio & Connectivity

• Ports: G5 offers the simplest high-bandwidth layout (4× 48 Gbps). S95F also has four HDMI 2.1 (eARC on one). Z95B provides two HDMI 2.1 + two HDMI 2.0—plan port usage if you run multiple 4K120/144/165 sources and eARC.
• Audio: Z95B includes a robust, Technics-influenced array; S95F carries a multi-speaker setup; all pass Dolby Atmos over eARC (DTS passthrough varies by brand/region—check manuals). 🔊

Thermal Design & Longevity

Z95B’s ThermalFlow uses a re-engineered airflow path to dissipate heat, helping sustain brightness and protect panel health during long HDR sessions. G5 and S95F rely on panel-care/firmware safeguards (pixel shift, logo dimming, compensation cycles). Use them—and avoid marathon static HUDs at max brightness. 🔧

Real-World Impressions

• Bright rooms / daytime sports & gaming: Samsung S95F feels tailor-made—matte anti-glare plus strong QD-OLED peaks equals confident daytime performance. LG G5 runs a close second on punch thanks to its tandem stack. 😍
• Dark-room cinema, reference tone-mapping: Panasonic Z95B stands out for near-black discipline and conservative mapping, with Dolby Vision & HDR10+ for format flexibility.
• Balanced “do-everything” buyer: LG G5 combines top-tier brightness, Dolby Vision, and four 48 Gbps HDMI for painless multi-device setups and PC gaming at 4K165. ✨

Common Mistakes to Avoid

• Using Vivid for movies—great in showrooms, inaccurate at home. Prefer Filmmaker/Cinema/Movie.
• Skipping HGIG on consoles—enable HGIG (where available) and run the console’s HDR calibration.
• Maxing motion smoothing—keep interpolation low for films.
• Not planning ports on Z95B—with only 2× HDMI 2.1, decide early which source gets eARC vs 120/144/165 Hz.
• If VRR flicker appears, use: Fix VRR Flicker on TV. 😉
