LG G6 OLED vs TCL QM8L

This comparison puts the LG G6 OLED and TCL QM8L side by side — two TVs measured against the same 28-spec sheet, with every meaningful gap scored and explained. On our weighted VS Score the LG G6 OLED finishes ahead, 84 to 79 — a solid lead.

The single biggest measurable gap is HDR formats: Dolby Vision vs Dolby Vision, HDR10+, HDR10, HLG. None of our retail partners currently lists the LG G6 OLED, so availability may be limited and price cannot factor into this comparison. A transparency note before you dive in: the spec sheets are LG G6 OLED 96% and TCL QM8L 86% complete. Anything unverified shows as Unknown and is left out of the scores — we never estimate a missing value.

Key real-world differences

The spec sheet pulls in both directions. These are the gaps big enough to shape the decision — with the actual figures, and what each one means in real-world use.

  1. HDR formatsPicture
    Dolby Vision vs Dolby Vision, HDR10+, HDR10, HLG — advantage TCL QM8L

    Support for more HDR formats means better contrast in more content.

  2. Peak brightnessPicture
    3,000 nits vs 5,000 nits — 40% more for the TCL QM8L

    Higher brightness makes HDR highlights pop.

  3. Chromecast built-inSmart features

  4. HDMI 2.1 portsConnectivity
    4 vs 2 — 2× more for the LG G6 OLED

    More full-bandwidth HDMI 2.1 ports connect more 4K/120Hz sources.

  5. Input lagGaming
    9 ms vs 10 ms — 10% less for the LG G6 OLED

    Lower input lag feels more responsive when gaming.

    On paper this is a win, but a gap this small is unlikely to be noticeable in daily use.

How the VS Score works — and what it can’t tell you

Every measurable spec is scored relative to this matchup: the best value here earns 100%, the worst 0%, and everything between scales linearly. Each spec then counts according to an editorial weight that reflects real-world impact — a battery-capacity gap moves the score far more than a colour-options list. The category scores above are the weighted results inside each group, and the overall VS Score rolls all of them together; the evidence line under each category names the specs that actually decided it.

Unknown values are never estimated. A spec a product doesn’t report simply drops out of that product’s scoring — it isn’t penalised with a guess — and a spec only one side reports can never produce a “win”. The trade-off is honest but real: a thinner spec sheet means a score built on fewer data points, which is why the completeness figures are disclosed under About this data.

Most importantly: a spec-sheet lead is not the same as a better product. Megapixels, gigahertz and benchmark points describe capacity, not experience — image processing, software optimisation, thermals, haptics and ergonomics decide how a device actually feels, and no table captures reliability or long-term support quality. Treat the scores as a structured summary of what can be measured, read the caveats under each key difference, and use the weight tuner to re-rank the comparison by what matters to you.
