TCL 65QM6K vs LG C5 (2026): Budget Mini-LED or OLED?

Most buyers who can stretch to a premium TV should pick the LG OLED evo AI C5 (OLED65C5PUA): it is the stronger choice for picture quality and gaming. The TCL 65QM6K is the better choice when budget comes first and you want a capable Mini-LED set without paying OLED money. This TCL 65QM6K vs LG OLED evo AI C5 comparison is based on manufacturer specs and what independent reviewers report, not our own testing.

The two TVs take different routes to a good picture. The LG uses self-lit OLED pixels, while the TCL uses a QD-Mini LED backlight with Halo Control. LG is the premium option here and TCL the budget one.

TCL 65QM6K vs LG C5: picture quality

This is where the two sets separate most clearly. The LG's 8.3 million self-lit pixels deliver what LG calls perfect black and perfect color, and reviewers consistently praise that combination. Its Brightness Booster adds brighter, more detailed highlights, and the α9 AI Processor 4K Gen8 handles AI Picture Pro and AI Super Upscaling. Reviewers also call its upscaling of lower-resolution content strong, which matters if you watch a lot of non-4K material.

The TCL does well for its tier. Its QD-Mini LED backlight with Halo Control is designed to limit blooming, and reviewers say it keeps contrast good. They also praise its vibrant, accurate color, especially in Filmmaker Mode. The TCL's weak spots are that peak HDR brightness is modest next to pricier sets, and that it does not match OLED for picture quality and motion. The maker lists a Motion Rate 480 with MEMC frame insertion, and the AiPQ Pro processor tunes clarity, contrast, color and motion.

Room lighting matters for the LG. Reviewers note that reflections can show on it, and that it is less bright than flagship OLEDs and Mini-LED sets. If your room is dark and you watch films in the evening, the LG's blacks are the main draw. If you want to spend less and don't need OLED-level blacks, the TCL is a sensible fit, though its peak HDR brightness is modest.

Winner: LG C5 for picture quality and motion. The TCL is the one to pick if budget decides.

HDR formats and cinema features

The LG supports Dolby Vision, HDR10 and HLG, plus FILMMAKER MODE. Its listing doesn't include HDR10+.

The TCL supports Dolby Vision IQ, HDR10+, HDR10 and HLG. It also carries IMAX Enhanced certification and a Filmmaker Mode. If your streaming or disc library leans on HDR10+, the TCL's format coverage is wider on paper. Reviewers specifically praise its Dolby Vision IQ, HDR10+ and IMAX Enhanced support.

Winner: TCL on format breadth, though the LG's panel is the one reviewers rate higher overall.

Gaming: HDMI ports and refresh rate

Both TVs are gaming-ready, but the LG gives more detail. It lists four HDMI 2.1 inputs (eARC on HDMI 2), a 120Hz native refresh rate with VRR up to 144Hz, NVIDIA G-Sync, AMD FreeSync Premium, ALLM, QMS and a 0.1ms response time. Reviewers praise the four HDMI 2.1 ports with 144Hz VRR.

The TCL has a 144Hz native panel with VRR up to 144Hz, and Auto Game Mode with FreeSync Premium Pro. It has four HDMI inputs, one of them eARC. TCL's listing does not specify the HDMI version, and it doesn't list a response time. A common criticism is that its input lag is higher than some rivals, which matters for competitive players.

Reviewers say the TCL's 144Hz panel suits smooth gaming, so it is a good budget gaming TV. But the LG offers more confirmed gaming features, and it adds G-Sync support that the TCL's facts don't mention.

Winner: LG C5 for serious gamers and multi-device setups. The TCL is fine for casual and budget-minded players.

Sound

Neither TV is a strong choice if you rely on built-in speakers. The LG has a 2.2 channel, 40W system with Dolby Atmos. Reviewers call it underwhelming, especially in the bass, and suggest a soundbar. The TCL has an Onkyo 2.1 system with a built-in subwoofer, Dolby Atmos and DTS Virtual:X. Reviewers still call its sound mediocre and recommend a soundbar.

The TCL's built-in subwoofer is a plus on paper, but reviewers don't rate it highly. The LG adds Auracast (Bluetooth LE Audio) support for several wireless headphones at once. Budget for a soundbar with either set. If you do, the speaker difference stops mattering.

Winner: a draw, with a slight edge to the LG for Auracast and to the TCL for its built-in subwoofer.

Smart platform and ease of use

The LG runs webOS 25 with AI Concierge, Magic Remote, Alexa and AirPlay 2. Its analyst verdict calls the webOS experience polished. Reviewers, however, find the AI features and redesigned remote gimmicky or uneven, so don't buy it for those.

The TCL runs Google TV with hands-free voice control, Chromecast built-in and AirPlay 2. Reviewers praise it as easy to use. If you already live in the Google ecosystem or cast a lot from your phone, the TCL's platform is the natural fit. If you prefer Alexa and a pointer-style remote, webOS is the better match.

The LG lists Wi-Fi 6E and Bluetooth 5.3 as well. TCL's facts don't list wireless specs, so we can't compare them. The LG also states its power use: 163.9 W operational and under 0.5 W on standby. The TCL's facts don't include a power figure.

Winner: depends on your ecosystem. Google TV suits casters, while webOS suits Alexa and Magic Remote fans.
