LG LG UA77 75" 4K HDR Smart LED TV Review

The LG UA77 75-inch 4K TV delivers a massive screen and LG's excellent webOS platform for under $600. It's a great value for size and smart features, though its picture quality is average and it's limited to a 60Hz refresh rate. Ideal for casual viewers and streamers on a budget.

If you're looking for a big-screen 4K TV on a budget, the LG UA77 75-inch model is a solid contender. It's a basic LED TV that gets you a massive 75-inch screen for well under $600, which is frankly a lot of screen for the money. It runs LG's excellent webOS smart platform, supports HDR10 and HLG, and includes some gaming features like VRR and ALLM. For corporate settings, streaming movies, or as a smart home hub, our data shows it scores quite well. But it's important to know what you're getting—and what you're not—at this price point.

The picture quality lands in the 43rd percentile in our database, which tells you it's a mid-range performer. The Alpha 7 AI processor does a decent job with 4K upscaling for HD content, and HDR support is there, but don't expect the eye-popping contrast or perfect blacks of a more expensive Mini-LED or OLED set. For gaming, the 60Hz native refresh rate and VRR support are fine for casual console gaming, but serious gamers will want a 120Hz panel. On the bright side, its smart features and connectivity are top-tier, scoring in the 91st and 89th percentiles respectively. webOS is smooth, intuitive, and packed with free channels.

For around $550, you're getting a massive 75-inch 4K TV with a great smart system. That's the value proposition, plain and simple. You're sacrificing some picture quality punch compared to pricier Mini-LED or OLED sets, but if screen size is your top priority and your budget is tight, this is a compelling way to get it. Alternatives at this size and price, like some Hisense or TCL models, might offer slightly better contrast but often can't match webOS for polish and ease of use.

This TV sits in a crowded field. The Hisense U6 Series Mini-LED is a direct competitor, often at a similar price. The Hisense typically offers better local dimming and contrast (thanks to its Mini-LED backlight), but LG's webOS is generally considered more refined than Hisense's smart platform. Stepping up to a Samsung Neo QLED or LG's own OLED evo series will give you a massive jump in picture quality and gaming features, but you'll pay two to three times as much. The Sony BRAVIA 5 is another step up in processing and color accuracy, again at a much higher price. For pure value and size, the LG UA77 holds its own against the Hisense U6, but if picture quality is king, you'll need to spend more.

Skip this TV if you're a home theater enthusiast who values top-tier contrast and HDR performance. The picture quality here is good, not great. Also, hardcore gamers should look for a TV with a 120Hz panel. And if you're putting a TV in a very bright room, its average peak brightness might be a struggle. For those users, consider stepping up to a Hisense U6/U7 series for better contrast or saving for a Samsung Neo QLED for brightness and gaming features.

Should you buy the LG UA77 75-inch TV? Yes, if your main goal is to get the biggest possible 4K screen for your dollar and you value a slick, user-friendly smart TV experience. It's a fantastic TV for a family room, basement, or corporate lobby where sheer size and easy streaming matter most. No, you should not buy this if you're a videophile craving the best HDR performance or a hardcore gamer who needs 120Hz. For those uses, the compromises in picture quality and refresh rate are too significant. But for most people who just want a huge, reliable, and smart TV without breaking the bank, it's a very sensible choice.
