Brightness: Mini-LED Firepower vs OLED Elegance
TCL C9K
- Mini-LED backlight with thousands of dimming zones.
- Holds higher sustained brightness across the entire screen.
- Ideal for sports bars, bright living rooms, and all-day TV.
- Can bloom around small bright objects in a dark scene.
LG G5
- OLED = self-emissive pixels → infinite contrast, absolute blacks.
- Full-screen brightness is lower than C9K, but HDR highlights sparkle more naturally.
- No blooming or haloing, even in pitch-dark rooms.
👉 Verdict: C9K dominates in sunlight; G5 is cinematic perfection at night.
Gaming: 144Hz vs 165Hz 🎮
TCL C9K
- Supports 144Hz on PC with VRR.
- Input lag ~6ms at 120/144Hz → lightning fast.
- Excellent for high-FPS shooters, esports, and competitive play.
LG G5
- Raises the bar with 165Hz VRR across HDMI 2.1 ports.
- Perfect match for next-gen PCs with RTX 4090/5090 or AMD GPUs.
- For consoles: PS5/Xbox cap at 120Hz, but HGIG + VRR ensure accurate HDR and smooth frame pacing.
- Response times essentially instant → motion clarity unmatched.
👉 Verdict: C9K = value and speed; G5 = cutting-edge with 165Hz, best for future-proof PC gamers.
HDR: Tone Mapping vs True Blacks
TCL C9K
- HDR10, HDR10+, Dolby Vision support.
- Strong highlights in bright scenes, great for animated content.
- Risk: Local dimming can flicker with VRR, and halos may appear.
LG G5
- HDR10, Dolby Vision, HLG + HGIG standard for gaming HDR accuracy.
- The OLED panel shows each pixel independently, revealing shadow textures without crushing.
- Dynamic Tone Mapping is available, but HGIG is the recommended choice for PS5/Xbox HDR calibration.
👉 Verdict: C9K is brighter in daytime HDR, but G5 paints a truer HDR canvas for films and games.
Processing Power: TCL AiPQ vs LG α11 AI Gen2
TCL C9K
- Uses AiPQ Processor Gen 3.
- Handles AI picture optimization, sharpness, and color tuning.
- Great for upscaling, but sometimes pushes contrast aggressively.
LG G5
- Debuts the α11 AI Processor Gen2.
- Up to 4× better AI performance vs α9 → sharper upscaling, cleaner motion.
- Features AI Picture Pro: real-time object detection & tone mapping.
- AI Sound Pro enhances spatial audio even on internal speakers.
👉 Verdict: LG’s α11 Gen2 is a leap in processing finesse, especially for 4K upscaling and HDR tone accuracy.
Longevity & Reliability
- C9K:
- LED tech = no burn-in.
- Perfect for static-heavy use (news tickers, ESPN logos).
- G5:
- OLED can suffer burn-in with marathon static HUDs.
- Protections: pixel shift, screen refresh, auto logo dimming.
- In varied use, risk is minimal.
👉 Verdict: C9K safer if you keep the TV on for hours with logos. G5 is safe for balanced usage.
Advanced Tips & Settings
- C9K:
- Use Game Mode + Local Dimming Medium to balance bloom.
- Stick to HDMI 1 & 2 for full 2.1 bandwidth.
- G5:
- Enable HGIG under Dynamic Tone Mapping for PS5/Xbox HDR accuracy.
- Run HDR calibration on consoles immediately after.
- For PC: activate 165Hz + VRR in GPU settings.
Mistakes to Avoid 🚫
- Expecting OLED-level blacks on the C9K → blooming is still there.
- Using LG G5 with DTM instead of HGIG for gaming → inaccurate HDR.
- Ignoring PC GPU setup → G5 only hits 165Hz if enabled in drivers.
- Assuming OLED burn-in is inevitable → protections make it rare.
Real-World Impressions
- C9K + FIFA 24: The pitch glows under stadium lights; crowd detail visible even at noon. ⚽
- G5 + Horizon Forbidden West (PS5): HGIG ensures skies look natural, shadows retain detail. 🌄
