The KYY 15.6″ portable monitor offers added value with a wholesome feature set

The KYY 15.6 inch portable monitor is a stylish and functional portable monitor that works well when traveling or as a permanent second monitor for home and office.

This portable pinboard is lightweight and sturdy, making it a solid accessory for gaming. It greatly expands the field of vision when using a mobile phone or a small screen game console.

The large screen easily adapts to landscape or portrait orientation. Its multi-mode display feature provides built-in flexibility to improve work productivity, while making leisure viewing fun and hassle-free.

Switching from one mode to another depends on the display capabilities of the host computer. If provided, you use the computer’s display and orientation settings for scene mode, HDR mode, and three-in-one display mode views. The combination of Duplicate Mode/Extend Mode/Second Screen Mode makes this model quite suitable for meeting sharing scenarios.

Overall, this KYY portable monitor packs an impressive list of features at an affordable price. It is currently available on Amazon in grey (pictured above) at the list price of $199.99, or black for $219.99. As of this writing, Amazon has “With Deal” pricing for both colors at $161.49.

Practical prints

The brightness rating of this device is 300 nits. By most standards, 300 nits is the midpoint for crisp, clear visual acuity. Most low-end devices display at 250 nits.

Color saturation is a bit below industry standard as this unit does not have Adobe RBG. But unless you’re planning to do a lot of graphics work and demand the best visual experience for gameplay and video viewing, not having Adobe RBG in the mix shouldn’t be a deal breaker.

Despite these two factors, I was very happy with the sharpness and brightness of the 300 nit display. It was as good as or better than my large screen laptops and desktop monitors.

Overall, this portable monitor works with Windows, Linux, Chrome OS, and Mac devices. It also works well with game consoles including PS3, PS4, Xbox One and Nintendo Switch.

Targeted tests

To evaluate portable monitors, I focus on a unit’s performance as a second screen. This is essential to ensure you make an appropriate selection.

Portable monitors attached to computers and game consoles are different from a full-fledged desktop monitor. Portable monitors are convenient. But they may not be suitable enough to meet all your expectations.

For example, I often drag windows onto a second screen to expand screen real estate when working on various documents or video presentations. They are useful when working on content creation or research.

Side-by-side: The 14″ x 8″ display screen in 16:9 aspect ratio provides a second, fitted viewing panel next to widescreen laptops.


It’s also an easy way to reduce the constant browsing of multiple windows spread across multiple virtual workspaces that all share a single monitor. Keeping my eyes on two screens side by side with different items displayed is a new usual work routine for me.

This KYY portable display has also done its job for graphics editing. It performed just as well as the more expensive units I use with my laptops and desktops.

My only gripe with this device is a finicky toggle on the left vertical edge that wasn’t always responsive to accessing the panel menu for brightness settings.

What’s inside

The 15.6-inch unit is a 1080P FHD IPS USB-C display. It’s not a touch screen. But its performance and price offer a nice collection of features.

Its slim 0.3-inch profile is pretty standard for portable monitors. The right vertical edge houses two full-function USB Type-C ports and a mini-HDMI port. The left vertical edge contains the on/off button and dial for audio and video function settings.

The first USB-C port is used for power. The second USB-C port is used for video transmission and power supply. The mini-HDMI port is used for video transmission but does not support power.

This distinction is important. The portable monitor does not need a wall outlet if the host computer or game console supports power supply through its USB Type-C port. But if you connect the two devices with the HDMI cable, you must use the AC power socket.

The KYY monitor comes with a USB-A to USB-C cable that can connect to the supplied power jack as well as other devices. Two USB-C cables are also included.

The included assortment of cables and plugs is compatible with most laptops, smartphones and PCs. However, not all smartphones are compatible.

You can plug a 3.5mm headset into a port located at the very bottom left of the vertical edge of the panel. Two one-watt speakers are integrated halfway up the left and right outer edges.

Final Thoughts

The KYY 15.6 inch portable monitor is a cost-effective solution to accessorize your computing time for working, watching videos and gaming. It does not require any additional software and only requires minimal configuration.

When connected by cable to a computer, the host machine’s display settings will automatically detect the second monitor. You just select the options it provides to know how you want it to work in tandem with your main screen.
