NEPTUNE Full Sun Full Sun 55" Review

The Neptune Full Sun 55" Outdoor TV is a specialized 4K smart TV built to live outside. Its 800-nit brightness fights sun glare, and its IP54 rating protects it from weather. It's expensive at $2899, but it's a solid choice for a permanent, weatherproof outdoor installation.

If you're looking for a TV that can handle the glare of a sunny patio or the chill of a winter deck, the Neptune Full Sun 55" Outdoor TV is built for exactly that. It's a 4K smart TV designed to live outside year-round, with an IP54 weather-resistant rating and an operating range from -22° to 122°F. That means it can shrug off rain, dust, and temperature swings, which is the whole point. It's powered by LG's webOS platform, so you get a familiar smart interface with streaming apps, and it's rated at 800 nits brightness to combat direct sunlight. The price is steep at $2899, but for a dedicated outdoor screen, it's a serious contender.

Picture quality is where this TV really shines, ranking among the absolute best right now in our outdoor TV database. The 800-nit brightness is the key spec here. It's bright enough to make 4K HDR content actually visible outdoors, even in daylight. The HDR10 support and 10-bit color panel help, but the main job is fighting glare, and it does that well. The connectivity is also top of the charts, with four HDMI 2.1 ports, Wi-Fi 5, Bluetooth 5.1, and Ethernet, so hooking up streaming boxes, game consoles, or speakers is easy. The 60Hz refresh rate and HDMI 2.1 mean it's fine for casual gaming, but it's not a dedicated gaming panel. The audio is about average with 16W speakers, so you'll likely want an external soundbar for better volume outdoors.

At $2899, the Neptune Full Sun is a premium outdoor TV. You're paying for the specialized weatherproofing and high brightness, not for cutting-edge indoor TV features like OLED or mini-LED. For a permanent outdoor installation where you don't want to worry about weather, this price makes sense. If you just want a cheaper indoor TV you occasionally move outside, you'd save a lot of money, but you'd risk damaging it. This is a tool for a specific job.

This isn't really competing with indoor flagships like the Sony BRAVIA 5 or Samsung Neo QLED. Those have better picture tech for dark rooms but aren't built for outdoors. For outdoor use, you might compare it to a SunBrite TV or a Samsung Terrace, which offer similar weatherproofing. The Neptune's brightness and webOS platform are strong points against those. You could also look at just buying a regular TV and a weatherproof enclosure, which might be cheaper but adds complexity. The Neptune is a cleaner, all-in-one solution if you have the budget.

Skip this if you're just looking for the best picture quality for your living room. TVs like the LG OLED C5 or Hisense U6 will give you a much better viewing experience indoors for less money. Also skip it if you only plan to use a TV outside occasionally; it's too expensive for that. And if you need a portable TV to move around, this 37-pound unit is not the answer.

Should you buy this? If you're building a dedicated outdoor entertainment space and want a TV that you can install once and forget about, yes. The weatherproofing and brightness are exactly what you need, and the performance there is excellent. But if you're just looking for a great TV for your living room, or if you think you'll only use it outside occasionally, this is a very expensive solution for a problem you don't really have. For those cases, a high-quality indoor TV and a careful, temporary setup is a much better value.
