TCL 75QM9K 75" VS Xiaomi TV S Pro Mini LED 2026 75"

In terms of display hardware, the TCL 75QM9K and the Xiaomi TV S Pro Mini LED 2026 are virtually identical across every measurable spec. Both use a QLED Mini-LED LCD panel at 4K (3840 x 2160) resolution, delivering the same 59 ppi pixel density on their respective 74.5″ and 75″ screens. They share the same 10-bit color depth, capable of rendering 1.07 billion colors, and both run at a 144Hz refresh rate — a meaningful advantage for fast-motion content and gaming smoothness compared to standard 60Hz or even 120Hz panels.

HDR support is also a complete match: both TVs cover HDR10, HDR10+, Dolby Vision, and HLG — the full suite of major HDR formats. This means neither forces a compromise regardless of the streaming platform or disc format you use. Viewing angles are equally matched at 178° horizontal and vertical, and both include an anti-reflection coating and an ambient light sensor for automatic brightness adaptation.

Based strictly on the provided display specs, these two televisions are in a complete tie. There is no meaningful differentiator between them at the panel level — every specification from resolution and color depth to refresh rate and HDR compatibility is identical. A purchase decision between these two models will need to rest on other spec groups such as processing, audio, or smart platform features.

The two TVs share a solid connectivity foundation — both offer HDMI 2.1, Wi-Fi 6, dual USB ports, a LAN port, and Miracast support. HDMI 2.1 is particularly important here, as it enables 4K@120Hz passthrough and Variable Refresh Rate for next-gen gaming consoles. Where they diverge, however, are in a few details that matter depending on your setup.

The TCL 75QM9K pulls ahead with 4 HDMI ports versus the Xiaomi's 3 — a practical advantage for users running multiple devices like a console, soundbar, streaming stick, and Blu-ray player simultaneously without relying on a switch. The TCL also carries a newer Bluetooth 5.4 versus the Xiaomi's 5.2, which offers modest improvements in connection stability and interference handling, though the real-world difference is subtle for most users. On the flip side, the Xiaomi TV S Pro includes a 3.5mm audio jack — absent on the TCL — which is a convenient option for plugging in headphones directly to the TV, a feature some households rely on.

Overall, the TCL 75QM9K has a slight connectivity edge thanks to its extra HDMI port and newer Bluetooth version, making it the more future-proof choice for multi-device living rooms. The Xiaomi's headphone jack is a niche but genuine advantage for a specific subset of users, so the ″right″ winner here depends on your peripheral priorities.

Audio is another category where these two TVs arrive at exactly the same destination. Both support the full Dolby ecosystem — Dolby Digital, Dolby Digital Plus, Dolby Atmos, and Dolby Audio — alongside DTS:X, covering the major surround sound formats used across streaming services, Blu-ray, and broadcast content. For users pairing either TV with an external soundbar or AV receiver, both also offer HDMI ARC and eARC, with eARC being the more capable option as it supports lossless, high-bandwidth audio formats like Dolby Atmos TrueHD passthrough.

Neither TV includes a subwoofer or any differentiating proprietary audio processing technology, and both rely on stereo speaker configurations. This means that while the format support is comprehensive on paper, real-world bass depth and spatial immersion from the built-in speakers alone will have the same fundamental limitations on both sets.

With every audio specification matching precisely, this group is a complete tie. Neither the TCL 75QM9K nor the Xiaomi TV S Pro offers any audio advantage over the other based on the provided data. Buyers prioritizing sound quality beyond the built-in speakers will find both equally capable of integrating with an external audio system.

Despite covering nearly identical screen sizes, these two TVs diverge noticeably in their physical footprints. The TCL 75QM9K is significantly slimmer at 51.1mm deep versus the Xiaomi's 73mm, and its total volume of roughly 69,635 cm³ is nearly half that of the Xiaomi's 116,580 cm³ — a meaningful difference for wall-mounted installs or tighter entertainment unit setups where depth clearance matters.

Weight tells a different story. The TCL is actually the heavier unit at ~30.4 kg compared to the Xiaomi's ~26.2 kg — a gap of about 4 kg that becomes relevant during installation, particularly for single-person wall mounts or ceiling rigs where every kilogram adds stress to brackets and fixings. Both support VESA mounting, so neither limits your options there. On operating temperature tolerance, the Xiaomi holds a slight practical edge with a range of 0°C to 40°C versus the TCL's 5°C to 35°C, making it marginally more suitable for installations in garages, sunrooms, or environments subject to temperature swings.

The design category doesn't have a single outright winner — it depends on priorities. The TCL is the better choice if a slim profile and compact volume matter most, while the Xiaomi is easier to handle and install thanks to its lower weight, and offers broader environmental tolerance. Buyers should weigh installation context carefully here.

Both TVs arrive well-equipped as smart platforms, sharing Chromecast built-in, AirPlay, Google Assistant, smartphone remote support, USB recording, and voice commands. For households already invested in either the Google or Apple casting ecosystem, both sets handle the basics equally well. Practical utility features like sleep timer, child lock, and a miserly 0.5W standby consumption are also identical across the board.

The only functional split in this category is voice assistant breadth. The TCL 75QM9K adds Alexa compatibility on top of Google Assistant, while the Xiaomi TV S Pro stops at Google Assistant alone. For users running an Amazon smart home — Echo speakers, Ring devices, smart plugs — this means the TCL can be natively integrated into that ecosystem without workarounds, a genuinely useful convenience that the Xiaomi cannot match.

The TCL 75QM9K takes a narrow but clear edge in this group purely on the strength of its Alexa support. It isn't a transformative advantage, but for Alexa-household users it adds real daily convenience. If your home runs on Google Assistant exclusively, both TVs are effectively tied in features.
