The LG UA73 is an entry-level 4K TV launched in 2025, designed for those who want an affordable large-screen experience without all the premium extras. It features an IPS panel, runs on LG\u2019s \u03b17 AI Processor (8th Gen), and includes the company\u2019s latest webOS 25 interface. Despite its simplicity, it comes with VRR and ALLM for smoother gaming \u2014 a rare bonus in this price class.<\/p>\n

Available in 43, 50, 55, and 65 inches, the UA73 is part of LG\u2019s Re:New program, which promises several years of webOS updates even after release.<\/p>\n

Design and Build<\/h3>\n

The LG UA73 has a straightforward and functional design. The bezels are thin, the frame is plastic, and the overall look is minimalistic. It\u2019s not a premium-looking set, but it feels solid enough. The stand uses two wide feet on each side, which means you\u2019ll need a broad surface unless you plan to wall-mount it.<\/p>\n

All the connections are located on the rear panel, pointing sideways and downward for easy access. There\u2019s no built-in cable management, but that\u2019s typical for this price range. The build quality is decent overall \u2014 nothing luxurious, but sturdy enough for everyday use.<\/p>\n

Included in the box are a standard remote control, a power cable, and basic documentation. The TV also supports LG\u2019s Magic Remote, which can be purchased separately.<\/p>\n

Smart Features and Performance<\/h3>\n

Powered by webOS 25, the LG UA73 offers the same smart TV platform found in LG\u2019s more expensive models, although it runs a bit slower. Navigation is simple and intuitive, and you get access to all the major streaming apps, voice search, and content recommendations.<\/p>\n

Unfortunately, like nearly all smart TVs today, the interface includes advertising tiles that cannot be disabled. Still, everyday use \u2014 streaming Netflix, YouTube, or Disney+ \u2014 is smooth and responsive enough.<\/p>\n

Because it\u2019s part of the Re:New initiative, LG promises extended software support, meaning the UA73 will stay up to date for several years.<\/p>\n

Picture Quality<\/h3>\n

The IPS panel on the LG UA73 delivers consistent colors and excellent viewing angles, making it great for bright rooms or group viewing. However, this panel type also means contrast and black levels are limited. Dark scenes tend to appear gray rather than truly black, and there\u2019s no local dimming to help deepen contrast.<\/p>\n

Brightness reaches around 300 nits, which is sufficient for well-lit interiors but too low to create impactful HDR highlights. Supported HDR formats include HDR10 Pro and HLG, but don\u2019t expect the kind of punch you get from OLED or QNED panels.<\/p>\n

Color reproduction is decent in SDR mode and improves after calibration, though reds and blues remain slightly off. Upscaling performance is good \u2014 low-resolution content from cable TV or streaming looks smoother than expected, with minimal pixelation. However, fine details can appear a bit soft.<\/p>\n

Gaming Performance<\/h3>\n

Gamers will appreciate that the UA73 supports Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM), reducing screen tearing and automatically switching to Game Mode when a console is detected. Input lag is impressively low at around 10 ms, ensuring responsive gameplay.<\/p>\n

That said, the TV is limited to 4K at 60Hz over HDMI 2.0, and VRR support doesn\u2019t extend to low frame rates (no LFC). Still, for casual console gaming on PS5, Xbox, or PC, it performs admirably.<\/p>\n

Sound Quality<\/h3>\n

Sound performance is modest. The UA73 features a 2.0-channel system with 20W total output. Dialogue is clear and well-centered, but bass is practically absent, and distortion can occur at maximum volume.<\/p>\n

\"The
The sound profile is well-balanced, so dialogue is clearly audible.<\/figcaption><\/figure>\n

It supports eARC, allowing high-quality audio passthrough to a soundbar or receiver, though there\u2019s no DTS support. Pairing this TV with a soundbar will make a big difference in overall experience.<\/p>\n

Connectivity<\/h3>\n

All three HDMI ports are HDMI 2.0, with additional inputs for two USB 2.0, Ethernet, optical audio, and antenna (RF and satellite). Wireless connections include Wi-Fi 5 and Bluetooth 5.1.<\/p>\n

\"The
The TV is limited to HDMI 2.0 bandwidth on all three ports. There\u2019s no ATSC 3.0 tuner, so 4K over-the-air streaming is impossible. The unit also features two USB 2.0 ports, a digital optical audio output, a 100 Mbps Ethernet port, antenna inputs, and a CI+ slot for premium channels. Wireless connectivity includes Wi-Fi and Bluetooth 5.1.<\/figcaption><\/figure>\n

There\u2019s no ATSC 3.0 tuner, meaning over-the-air 4K broadcasts aren\u2019t supported. For most users streaming content online, this won\u2019t be a deal-breaker.<\/p>\n

Conclusion<\/h3>\n

The LG UA73 is a basic but capable 4K TV for those who value simplicity, reliability, and wide viewing angles over cinematic performance. It\u2019s ideal for bright living rooms, bedrooms, or kitchens where you\u2019re watching TV casually or streaming light entertainment.<\/p>\n

However, movie lovers seeking deep blacks, vibrant HDR effects, or powerful sound should look elsewhere \u2014 possibly to LG\u2019s QNED or OLED ranges.<\/p>\n
