28 facts in comparison
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.
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.
Support for more HDR formats means better contrast in more content.
Higher brightness makes HDR highlights pop.
Cast content from phones and laptops without a dongle.
More full-bandwidth HDMI 2.1 ports connect more 4K/120Hz sources.
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.

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.
