LG OLED55G5WUA 55" VS Xiaomi TV S Pro Mini LED 2026 55"

The most fundamental difference here is panel technology. The LG G5 uses OLED, where each pixel generates its own light and can switch off completely, delivering true infinite contrast, perfect blacks, and exceptional shadow detail. The Xiaomi S Pro relies on Mini-LED LCD (QLED), which uses thousands of tiny backlight zones to approximate deep blacks — a significant improvement over standard LED, but still unable to match OLED's per-pixel precision. In practice, this means the LG will produce more cinematic HDR highlights with no blooming around bright objects on dark backgrounds, a visible artifact that can still affect even premium Mini-LED panels.

Where the Xiaomi pushes back is in refresh rate and HDR format support. Its 144Hz panel has a clear edge over the LG's 120Hz for fast-motion content and gaming, reducing motion blur and enabling smoother frame interpolation. It also adds HDR10+ support — a dynamic metadata standard that the LG omits — meaning HDR10+ mastered content (common on Amazon Prime Video) will be tone-mapped more accurately on the Xiaomi. Both TVs cover Dolby Vision, HDR10, and HLG, so this gap only matters for HDR10+ specific content.

All remaining specs — 4K resolution, 10-bit depth, 1.07 billion colors, 80 ppi, anti-reflection coating, ambient light sensor, and 178° viewing angles in both axes — are identical. Overall, the LG G5 holds the display quality edge for cinematic and everyday viewing thanks to OLED's contrast superiority, while the Xiaomi S Pro has a measurable advantage for gaming and HDR10+ content. Which panel ″wins″ depends almost entirely on the user's primary use case.

Port count is where the LG G5 pulls ahead most concretely. Its 4 HDMI 2.1 ports and 3 USB ports give it a meaningful practical advantage over the Xiaomi's 3 HDMI and 2 USB — a difference that matters in a fully loaded entertainment setup with a console, soundbar, streaming stick, and Blu-ray player all competing for connections. Both TVs run HDMI 2.1, so bandwidth capabilities (48Gbps, 4K@120Hz passthrough) are equal; the LG simply offers more of them.

Wireless connectivity also tips in the LG's favor. It supports Wi-Fi 6E, extending into the 6GHz band for less congestion and lower latency in dense network environments, while the Xiaomi tops out at Wi-Fi 6 (5GHz/2.4GHz only). Similarly, the LG's Bluetooth 5.3 edges out the Xiaomi's 5.2, offering marginally improved connection stability and power efficiency — a minor but real difference for wireless audio accessories. Both share Miracast screen mirroring and a wired RJ45 port for stable ethernet connections.

The one spec favoring the Xiaomi is its 3.5mm audio jack, absent on the LG — useful for directly connecting wired headphones without a separate adapter or Bluetooth pairing. That said, this is a niche convenience rather than a decisive factor for most users. On the whole, the LG G5 holds a clear connectivity edge, particularly for power users with multiple peripherals and demanding home network setups.

For a built-in audio comparison, the single most impactful differentiator is the LG G5's integrated subwoofer. A dedicated low-frequency driver physically changes how bass is reproduced — delivering fuller, more grounded sound for action sequences and music without relying on an external speaker system. The Xiaomi S Pro has no subwoofer, meaning its bass output depends entirely on its stereo drivers, which typically struggle to reproduce deep frequencies convincingly at this screen size.

Flipping the advantage, the Xiaomi adds Dolby Digital Plus support, which the LG lacks. DD+ is an enhanced codec that carries higher bitrates and is widely used for streaming services like Netflix and Disney+, enabling more detailed audio encoding than standard Dolby Digital. In practice, this could yield marginally richer audio from streaming sources — though the real-world gap depends heavily on the quality of the TV's amplification and drivers, which the specs don't quantify. Both TVs otherwise share an identical audio format foundation: Dolby Atmos, Dolby Audio, DTS:X, and full HDMI ARC/eARC support for passthrough to an external soundbar or AV receiver.

Taken together, the LG G5 has the clearer advantage for users who rely primarily on the TV's built-in sound system, since the subwoofer provides a tangible hardware benefit. The Xiaomi's Dolby Digital Plus support is a useful codec addition but is less impactful than a physical driver — and becomes largely irrelevant if either TV is paired with a dedicated soundbar, which eARC on both makes straightforward.

Two design specs dominate this comparison, and they point in opposite directions. The LG G5 is dramatically slimmer at 27.9 mm thick versus the Xiaomi S Pro's 71 mm — more than 2.5 times thicker. For wall-mounted installations, this difference is immediately visible: the LG sits flush and portrait-like against the wall, while the Xiaomi protrudes significantly. This is a direct consequence of panel technology — OLED requires no backlight assembly, enabling a svelte chassis, whereas Mini-LED LCD demands physical depth to house its backlight array and diffusion layers.

Weight tells the opposite story. The LG G5 comes in at 22,089 g (roughly 22 kg), nearly double the Xiaomi's 12,900 g (approximately 13 kg). This is a substantial difference during installation — a 22 kg panel typically requires two people and a wall mount rated for higher loads. The Xiaomi's lighter build is considerably easier to handle, reposition, or mount solo, and puts less long-term stress on wall fixings. Both TVs support VESA mounting, so the choice of mount is open for either.

In summary, these two designs involve a real trade-off. The LG G5 wins decisively on aesthetics and wall-presence with its ultra-slim profile, making it the stronger choice for minimalist or gallery-style installations. The Xiaomi S Pro's significant weight advantage makes it the more practical option from a handling and installation standpoint. Neither has an across-the-board design edge — the right choice depends on whether thinness or manageability matters more to the buyer.

Three differences stand out in this group, and two of them are significant. On power consumption, the Xiaomi S Pro draws 230W during operation versus the LG G5's 125W — nearly double. Over hours of daily use, this gap compounds into a meaningful difference in electricity costs across the TV's lifespan. It also reflects the fundamental efficiency advantage of OLED, which only powers active pixels, over a Mini-LED backlight that illuminates a full array continuously.

The warranty gap is equally striking. The LG G5 carries a 5-year warranty against the Xiaomi's 1-year coverage — five times longer. For a premium-tier purchase, this is a substantial long-term value consideration, covering potential panel or component failures well beyond the standard window. Combined with the power savings, the LG's total cost of ownership looks considerably more favorable over time. On the ecosystem side, the LG also adds Amazon Alexa compatibility, which the Xiaomi lacks — a practical advantage for users already embedded in Amazon's smart home ecosystem.

The shared feature set is extensive: both offer Chromecast built-in, AirPlay, Google Assistant, smartphone remote control, USB recording, and identical standby consumption. Neither supports Apple HomeKit or Siri. Overall, the LG G5 holds a clear advantage in this group — its dramatically lower power draw, far longer warranty, and broader voice assistant support give it the edge on every meaningful differentiator.
