Hisense U7SG vs LG C5 OLED
This comparison puts the Hisense U7SG and LG C5 OLED 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 Hisense U7SG finishes ahead, 98 to 69 — a decisive result.
The single biggest measurable gap is peak brightness: 3,000 nits vs 1,200 nits. None of our retail partners currently lists the Hisense U7SG, so availability may be limited and price cannot factor into this comparison. A transparency note before you dive in: the spec sheets are Hisense U7SG 89% and LG C5 OLED 96% complete. Anything unverified shows as Unknown and is left out of the scores — we never estimate a missing value.

Score breakdown
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.
