Samsung QN70H 85 Inch Neo QLED 4K Smart TV vs TCL 85-inch QM8L UHD TV

Both are 85-inch 4K Mini LED TVs, but they aim at different buyers. The TCL QM8L is the brighter set on paper, rated up to 6000 peak nits, and adds Dolby Atmos with a Bang & Olufsen audio system, so it suits a bright room and buyers who want big sound without a soundbar. The Samsung QN70H runs Tizen with Alexa support and a slim AirSlim design, which suits Samsung households and wall mounting. No current prices were provided for either set, so compare live store prices on Deal.ai before deciding.
