LG UHD AI UA77 4K LED Smart webOS TV 2025
This article takes a closer look at LG’s UA7700PUB 4K TV, a budget-friendly model aimed at shoppers who want a big screen from a major brand without spending much. The LG UA77 is one of the most affordable name-brand TVs available today—starting at just $229 for the 43-inch model and topping out at $799 for the massive 86-inch version. It comes in a full lineup of sizes, including 43″, 50″, 55″, 65″, 75″, and 86″.
Before diving in, it’s worth noting a trend that’s become clear over the past few years: the big three brands—LG, Samsung, and Sony—have been releasing entry-level TVs that often fall short in performance. Meanwhile, competitive brands like Hisense and TCL continue to offer better picture quality and features at similar price points. This is something to keep in mind when shopping for a value TV.
With that in mind, the LG UA77 is a model that doesn’t deliver much in terms of premium performance.

Picture Quality and Performance
One of the most noticeable limitations of the UA77 is its low brightness in both SDR and HDR modes. HDR content lacks punch, and highlights fail to stand out. The TV also suffers from weak contrast and shallow black levels, causing dark scenes to appear washed out—especially if you watch in a dim or dark room. The absence of local dimming further contributes to flat blacks and visible backlight bleed.
Color reproduction is passable but not particularly vivid, and its overall impact is limited by the modest peak brightness.
When it comes to reflection handling, the UA77 struggles in bright rooms. It can manage mild glare, but strong ambient light easily overwhelms the screen.
Strengths
Despite its shortcomings, the UA77 does offer some meaningful benefits, thanks largely to its IPS panel, which provides excellent wide viewing angles. It also handles low-quality content respectably, delivers decent 4K upscaling, and gives you access to LG’s slick and user-friendly webOS smart TV interface.
Gamers will appreciate the TV’s low input lag and VRR support, making it suitable for casual and competitive play.
All pros and cons mentioned above are sourced from reputable online reviews.
On the consumer side, however, feedback is overwhelmingly positive. Many customers praise the TV for its value, picture clarity, and ease of use. As always, it’s worth checking the TV out for yourself to see if it meets your needs. (Links to customer reviews can be found in the description.)

Summary
The LG UA77 is a budget-friendly 4K TV that earns strong customer reviews for its sharp picture, responsive smart interface, and solid overall value. However, professional reviewers and more discerning users highlight several weaknesses, including limited brightness, modest contrast, glare issues, and occasional color inconsistencies. The built-in speakers are serviceable but benefit greatly from a soundbar.
If you’re seeking an affordable TV with wide viewing angles, smooth smart features, and decent gaming performance, the LG UA77 is worth considering—just be aware of its performance limitations, especially in dark rooms or HDR viewing.
