The LG 15.6″ 15Z90RT-N.APB4U1 is a standout in the ultra-portable laptop category, offering a sleek, lightweight design without compromising on performance. Perfectly tailored for users who need a reliable workhorse that’s easy to carry, this laptop combines premium build quality with solid performance. Whether you’re a professional looking for a portable office solution, or someone who values a lightweight, versatile laptop for media consumption, the LG Gram SuperSlim delivers on all fronts. But does it actually perform as well as its slim form factor promises? Let’s explore the details.

Under the hood, the 15Z90RT is powered by the Intel Core i5-1340P processor, a quad-core chip from Intel’s 13th generation lineup. With a base clock speed of 1.80 GHz and the ability to boost up to 4.60 GHz, this chip offers excellent performance for everyday tasks like office productivity, web browsing, and video conferencing. Whether you’re working on a large spreadsheet, attending virtual meetings, or multitasking with several browser tabs open, this processor handles it all without breaking a sweat. It’s an excellent choice for users who need solid performance for moderate workloads, but it’s not designed for intensive tasks like video editing or high-end gaming.

On the graphics front, the integrated Intel Iris Xe GPU takes care of light gaming and media consumption. It won’t be pushing out frame rates on AAA titles, but for casual games or streaming your favorite shows on its stunning OLED display, it does the job just fine. The OLED screen itself is one of the key highlights of this laptop. With vibrant colors, deep blacks, and impressive contrast ratios, it offers a much superior viewing experience compared to traditional IPS panels. The 1920×1200 resolution provides crisp visuals, and if you’re into media consumption, this display will absolutely impress with its rich, lifelike picture quality. In terms of color accuracy, it covers a significant portion of the sRGB spectrum, making it suitable for casual content creation or photo editing.

The laptop also comes with 16GB of RAM, which is more than enough for multitasking. You can comfortably run a handful of applications simultaneously—whether it’s a few browser tabs, an email client, or a video conferencing tool. The 256GB SSD storage is on the smaller side, but it’s NVMe, meaning it offers fast read and write speeds that contribute to the laptop’s overall snappy performance. Whether you’re booting up the laptop, opening applications, or saving files, the SSD ensures there’s no frustrating delay.

When it comes to real-world usage, this laptop excels in its core functions. Office productivity tasks like word processing, spreadsheets, and web browsing are a breeze. Streaming 1080p or 4K content is equally smooth, thanks to the combination of the fast SSD and that vibrant OLED screen. Media playback looks stunning, whether you’re watching movies or video editing on a basic level. The 15Z90RT also performs well for video conferencing, with a responsive webcam and clear microphone output, making it an ideal option for remote work or virtual classes.

Now, as we talk about its thermal performance, the LG Gram SuperSlim does an impressive job of staying cool, even when you’re working for extended periods. Under light tasks like web browsing and word processing, the laptop remains cool to the touch, with minimal fan noise. Under more demanding loads, like streaming or working with several apps open, the fans do kick in, but they remain relatively quiet compared to some of its competitors in this category. This makes it an excellent option for users who need a quiet environment for work or study. However, keep in mind that this slim chassis means that the cooling system is compact, and under heavy loads, the laptop can get a bit warm on the bottom. It’s not a major issue for short sessions, but long periods of gaming or video rendering could see some thermal throttling.

Battery life on this laptop is solid, with around 8 to 10 hours of real-world use, depending on the intensity of your tasks. This range is more than enough for a full day of work or study, but it’s always a good idea to carry the charger just in case. When it comes to charging, the LG Gram SuperSlim can top up fairly quickly, and the included charger is compact, making it easy to throw in your bag without adding much weight.

The keyboard on the 15Z90RT is surprisingly comfortable, considering the laptop’s thin design. The key travel is satisfying, and the layout is clean, with a full-sized set of keys, including a number pad. Long typing sessions are comfortable, and the backlit keys are a nice touch for working in low light. The trackpad is large and responsive, offering accurate cursor movement and multi-finger gestures without any noticeable lag. There’s also a fingerprint sensor integrated into the power button for secure logins, which adds a layer of convenience.

In terms of ports and connectivity, the LG Gram SuperSlim offers a good range of options. You get two USB-C ports, one of which supports Thunderbolt 4 for fast data transfer and external monitor support. There’s also a USB-A port, an HDMI port for connecting external displays, and a microSD card reader for additional storage expansion. On the wireless front, the laptop supports Wi-Fi 6, ensuring fast and stable internet connections, as well as Bluetooth 5.1 for connecting peripherals.

As for the build quality, the LG Gram SuperSlim does not disappoint. The MIL-STD 810G certification ensures that it can withstand some degree of physical stress, making it durable enough for everyday carry. Despite being made of magnesium alloy, which is both strong and lightweight, the laptop feels premium and solid, with no flex when you press on the chassis. At just 13mm thick and weighing around 1.1kg, it’s one of the lightest 15-inch laptops you’ll find, making it perfect for users who need something portable without sacrificing screen size.

When you compare this laptop to other models in a similar price range, the 15Z90RT stands out due to its OLED display, light build, and good overall performance. However, its competitors, like the Dell XPS 15 or the MacBook Air with the M2 chip, may offer better performance in some areas, such as processing power or battery life. That being said, if portability and display quality are your top priorities, the LG Gram SuperSlim is hard to beat.

In conclusion, the LG 15.6″ 15Z90RT-N.APB4U1 is an excellent choice for users who need a portable, stylish, and high-quality display laptop for everyday tasks. Its lightweight design, fast performance, and stunning OLED screen make it a fantastic option for office workers, students, and media consumers alike. However, for users who demand more intensive processing power or gaming performance, you might want to look at alternatives. At its current price, this laptop offers good value for those who prioritize portability and a top-tier display.
