Choosing a budget 4K Smart TV can sometimes feel more confusing than picking a high-end one — such as deciding between the LG G5 vs C5 or LG C5 vs C4, especially when two models appear nearly identical on paper. That’s the case with the LG UA77 (2025) and LG UA75 (2025) — both positioned as affordable 4K LED TVs offering webOS smart features and solid everyday home-entertainment performance.
In this comparison, we’ll break down what you actually get from each model and answer the key question: Is there any real difference? By the end, you’ll know exactly which one is the better buy — and why the answer mostly comes down to availability and price.
LG UA77 (2025) Short Overview
The LG UA77 is a 2025 4K LED Smart TV designed for affordable home entertainment. It uses a direct-lit LED display with a native 60 Hz refresh rate, making it suitable for casual streaming and everyday viewing. Powered by the α7 AI Processor Gen8, it supports features like 4K upscaling, Dynamic Tone Mapping for improved HDR10 and HLG playback, and Filmmaker Mode for more accurate movies.
As a webOS TV, the UA77 gives access to major streaming apps, LG Channels, voice assistants, and Home IoT control. It also includes ALLM and VRR up to 60 Hz, so gaming performance is smooth enough for console users — though motion handling remains entry-level.
Overall, the UA77 provides a simple and reliable Smart TV experience with decent picture quality for the price.
