Uperfect S 4K Portable Monitor Review

A Portable Monitor With A 4K Touchscreen Display

The Uperfect S is a 15.6 inch monitor with a 4K resolution, USB C PD ports, and a built-in stand.

In this review, I am going to share my thoughts on it after using it for a little over a month. How does it compare to the 16-inch 1660P 120Hz monitor from Uperfect I reviewed last month?

Let’s begin by looking at the specifications before I get to what I like and don’t like.

There are several ports on the monitor for connecting various devices.

  • Two USB C PD ports – Used for both power and data. If your device has a USB C PD port, it can be used with a single cable.
  • One mini HDMI – For audio and video, and Uperfect includes a mini HDMI to HDMI cable to use this port with HDMI devices.
  • 3.5mm headphone port – So you can connect headphones to the monitor instead of your device. Can be more convenient depending on setup.
  • Micro USB – A port that lets you connect computer peripherals like a mouse or keyboard.

With my MacBook Pro it only takes one cable to use the display. It is, however, limited to 75/100 brightness. The touchscreen works on Mac, but my experience with the touch functionality was better on Windows.

With my gaming desktop computer, I connect the display with the included mini HDMI to HDMI adapter. The touchscreen works great on Windows and is useful when surfing the web and editing photos/drawings.

Neither Mac or Windows had problems running a 4K resolution at 60Hz. I could scale the content in the operating system and choose whether I wanted text to be small or large.


With the push of a button on the left side of the stand, the menus are accessed.

This is where you can change display settings, picture modes, enable and disable features like HDR and FreeSync, rotate the display, and lock the rotation.

Other Features

There is a gravity sensor in the display that will automatically rotate the display depending on how you hold it. This is useful if you are using the display on your lap.

The rotation can also be changed and locked in the menus.

If you don’t have speakers or headphones, there are two small speakers on the monitor that are good enough to listen to videos and podcasts on.

They don’t have any bass, so don’t plan on depending on them for listening to music.


The built-in stand is used when using the monitor on a desk. If you want to use it on your lap, you can close it by folding it towards the back of the display.

Since the stand holds the ports, it can’t be removed. It doesn’t protect the front in any way when folded together.

I’d say you can set the angle to 40-85°. Lower than that and the display falls over, and it doesn’t go higher than about 85°

In The Box

Here is what you get in the box with the monitor:

  • 2 USB C to USB C cables
  • USB A to USB C cable
  • Mini HDMI to HDMI cable
  • Wall power adapter

Size And Weight

It weighs 2.24 lbs (1.02 kg) and measures 14.13 x 8.79 x 0.2 inches (359 x 223.3 x 5 mm).

It’s very thin and easy to slide into a backpack.

My Review


High resolution

A 4K resolution on a 15.6-inch display looks amazing. It’s very sharp, clear, and easy to read text.

As long as you don’t need a higher refresh rate than 60Hz, it’s excellent.

Built-in stand

The built-in stand is great to have. It’s not removable, so it’s always there and easy to set up.

I wish it would also function as a cover for the front to protect the display when not in use.

Easy to understand the buttons and menus

The monitor only has one button, and that is used to open and close the menus. Everything else is done by using your fingers.

Straightforward, and a lot of settings/modes to choose from.


I am not somebody that uses touchscreen displays with Mac or Windows, but it’s pretty neat to have it.

It’s not as responsive as the touchscreen on my phone or tablet, but for web browsing, I can see myself using it.

Don’t Like

No VESA support

There is a built-in stand, but there are no VESA mounting holes. I have VESA mounts on my desk and would love to have this monitor above my main monitor, but I can’t since there is no great way to mount it.

The brightness limit and how it works

This was something I complained about on the other Uperfect monitor as well.

The problem is that when I use the monitor with my MacBook and I use a single USB C cable, the monitor resets if I go above 75 brightness.

It’s fine that it can’t go to full brightness without additional power, but I wish it wouldn’t let me even try to exceed it in the settings, so I don’t have to deal with the reset.

Now the screen goes black for a couple of seconds, before turning back on with a lower brightness.


The Uperfect S 4K is not a bad portable monitor. Its 4K display is gorgeous and a great monitor to consume content on.

I don’t see it as a product for gamers, not only because of the 60Hz refresh rate but running 4K games on a 15.6″ monitor doesn’t make much sense.

If you are a photo- or video-editor and are looking for a beautiful display to work on, this is a superb choice. Especially if you’re interested in the touchscreen functionality.

However, I wouldn’t get it for the touchscreen if you’re on Mac. Only if you’re a Windows user.
