10 Best Portable Monitor For Iphone 2026 in the United States

The MNN 4K Portable Monitor features a 15.6-inch screen with a sharp 4K Ultra HD resolution, delivering clear and detailed images—ideal for watching videos, photo editing, or gaming. Its IPS panel provides wide viewing angles and vivid colors with 100% Adobe RGB support, which is especially beneficial for those who prioritize color accuracy. The screen brightness of 400 nits is suitable for indoor use but might be somewhat dim in bright outdoor environments. Additionally, the matte surface helps reduce glare, improving visibility under various lighting conditions.

In terms of connectivity, the monitor is equipped with two USB-C ports and a mini HDMI port, enabling easy connections to laptops, gaming consoles, and even smartphones like the iPhone (though some phones may require extra power to operate the monitor). The USB-C ports support both video transmission and power delivery, minimizing cable clutter—a great feature for travel or mobile work. The monitor is also slim and lightweight at just 1.8 pounds, making it easy to carry in a backpack.

The monitor lacks touchscreen capability, so interaction is limited to the connected devices. While it supports HDR and has a 60Hz refresh rate, it might not meet the needs of users seeking ultra-smooth gaming performance. The built-in speakers offer added convenience but are not a substitute for dedicated audio equipment. This portable monitor is an excellent choice for those needing a high-quality, color-accurate external display, especially for tasks like photo editing, streaming, or casual gaming; however, users requiring touchscreen functionality or brighter outdoor visibility may want to explore other options.

The ViewSonic TD1655 is a 15.6-inch portable monitor with a Full HD 1080p resolution, offering clear and sharp visuals that are well-suited for watching videos, browsing, or working on the go with your iPhone. It features an IPS touchscreen that supports 10-point touch, making interactions like swiping and writing smooth and natural, which is handy if you want to use touch controls similar to your phone. Its slim design (just 0.6 inches thick) and light weight (about 2.2 pounds) make it easy to carry in a backpack or purse, which is great for portability.

The monitor uses USB-C for both video and power, reducing cable clutter since you only need one cable to connect and charge it, provided your iPhone supports USB-C connection or you have the appropriate adapter. The included built-in stand with a magnetic cover allows you to easily position the screen in portrait or landscape orientation, adding flexibility for different viewing needs. It also has dual speakers, adding convenience if you want sound without extra devices.

Because it relies on USB-C for power, users with older iPhones that use Lightning ports may need additional adapters or hubs, which can add complexity. The monitor uses a matte screen surface which helps reduce glare but might slightly soften colors compared to glossy screens. Additionally, it requires one A battery, likely for some built-in function like the stand or speakers, which is a minor extra to keep in mind. This monitor provides a good balance of size, image quality, and touch capability for iPhone users seeking a portable secondary screen, although some might need adapters to connect it seamlessly.

The ARZOPA Portable Monitor offers a decent 15.6-inch Full HD (1080P) IPS display, ensuring vibrant and clear visuals with a wide 178° viewing angle. This makes it suitable for those who need a larger screen on the go, including iPhone users who want to extend their display for various tasks. The monitor features an ultra-slim design, weighing only 1.6 pounds and measuring 0.35 inches in thickness, making it highly portable for travel or daily commutes.

The built-in kickstand is a handy feature, allowing you to adjust the viewing angle for comfort easily. Connectivity is a strong point, with USB-C and HDMI ports enabling straightforward plug-and-play compatibility with a wide range of devices, including laptops, PCs, gaming consoles, and smartphones without additional software or drivers. However, the monitor's glossy screen surface might lead to reflections, which could be distracting in brightly lit environments.

Another potential downside is the lack of an internal battery, meaning it will always need to be connected to a power source, which might limit its portability. While the monitor supports multiple display modes, its performance might be constrained when connected to less powerful devices like smartphones, potentially affecting the user experience. This ARZOPA monitor could be an excellent choice for those needing a secondary or extended display in a lightweight and travel-friendly package, though users should consider their specific needs and environment when deciding.
