Multiple Screens

For over 30 years, I have been a tech enthusiast who had also been in the Information Technology (IT) field for nearly two decades. Over that time, I have seen people increasingly use mobile devices more than desktop computers, and therefore, the need for portable displays for use as secondary screens has also increased. Not only does it add more screen real estate, it could also have better health implications for your eyes, posture, attention span, and stress.

Acer PM161Q

Shopping For Portable Monitors

Last year, I purchased an Acer PM161Q ($130) to supplement my Surface Pro 5 at the time. It was a first-of-its kind, portable monitor that was lightweight, but it also was a nightmare of a device to use due to compatibility issues. First, it would not work with any of the Surface Pros and HP laptops, but I was able to connect it to a friend’s Dell laptop. At the time, I could not find information from Acer or Microsoft about why the monitor would not work with the Surface Pro or HP laptops. Turns out, Thunderbolt 3 was required.

Fast-forward 7 months later, and more computers now support Thunderbolt 3 — except for the Microsoft Surface devices (by design) because Thunderbolt 3 is vulnerable to allowing a hacker to grab data from your computer. Any computers made before 2019 should avoid using Thunderbolt 3, in fact. Security issues aside, the Acer PM161Q did work so well with my work laptop, the Dell XPS 13 P73F (supports Thunderbolt 3), my manager decided to get one for the team to help us do our jobs easier when on travel.

More portable monitors have been released since.

I had previously evaluated the 15.6″ Mukesh X1 ($150) and liked it quite a bit because it did not require a Thunderbolt 3 USB-C port, but what it did lack was what I missed from the Surface Pro devices: a touch screen. Most of the decent-looking displays with touch capability ran for at least $100 more than the Mukesh X1, but during the search, one device very much captured my attention: the 15.6″ UPerfect MDS-156G16 ($305). What made it stand out? Touchscreen, built-in battery, IPS, AND 4 speakers! A similarly-equipped Asus Zenscreen MB16AMT (with 25% less battery capacity) costs $340.

What’s Good? What’s Bad?

  • Plug and Play
    • Worked right away when connected to a Samsung Galaxy S9+ and Dell XPS 13 P73F laptop. No drivers needed to be installed
    • With the Samsung phone (USB-C to USB 3.1), Samsung’s DeX Desktop turned the UPerfect into a Windows-like interface
      • DeX can be turned on/off for use as a Desktop or to mirror phone’s screen
      • With a Bluetooth mouse and keyboard, you could literally make your phone turn the UPerfect into a computer
    • Does not require USB-C Thunderbolt 3
      • Video worked with 2015’s Surface 3 (non-Pro version) via Mini DisplayPort-to-HDMI
  • 10-point Multi-Touch (with USB-C to USB-C, USB-C to USB 3)
    • Pinch and Zoom capability just like on a tablet/phone
    • Touch behaved differently in Windows 10 when used as Extended or Duplicate Display (See CONS section below)
  • Priced well for a product of this type
  • Started up in a few seconds, ready to display whatever was on the phone or laptop
    • Note: “Realtek” logo comes up on power-on. Yes, the ubiquitous, Taiwanese chip maker
  • 10,800 mAh (3.8V) Battery makes it more portable without the need for an AC outlet or other power source
    • Equivalent to 41 Wh capacity (meaning: you can power a 41W device for almost an hour)
  • Monitor consumes 11.7W (9V @ 1.3A), though my battery station reported 10W (at full brightness)
    • When “No Signal” was received, the power drew only 7W (at full brightness)
    • Less power drain on your laptop, making it very suitable for on-location photo/video editing or gaming
    • Can be set up for use as a power bank on its own to charge your phone. See TIPS section below
      • In this mode, the monitor’s battery will run out faster

Monitor consumes up to 11.7W (9V @ 1.3A), helping it last for nearly 4 hours at maximum brightness

Input/Output Ports

The following explains what each connection port can/cannot be used for:

  • USB-C (left of display)
    • As input: Touch and audio/video (depends on cable, connected device, and must support Thunderbolt 3 or USB 3.1)
      • Touch, audio, and video worked with Samsung Galaxy S9+ phone (USB 3.1) and Dell XPS 13 P73F laptop (Thunderbolt 3)

    • As output: If configured, can be used to charge other devices (ie. phone)

Power Draw

To calculate how long the display’s built-in battery could last, use this formula: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device

  • There is about a 15% power loss when using a battery
  • At the highest brightness, about 10W was consumed by an active display (only 7W when no signal was received)
    • With a 10,800 mAh battery, that translates to roughly 41 Wh at 3.8V (Wh = mAh x Voltage / 1000)
      • Highest brightness: 41 Wh x 0.85 / 10 W used = 3.5 hours
  • The display can be used for 3.5 to 5 hours at its highest brightness. Longer at lower brightness levels
    • Manual states up to 7 hours of use at 50% brightness
  • If monitor is set to charge connected, mobile devices, the battery will deplete faster
    • Manual claims up to 4 hours

Final Thoughts

Credit: UPerfect

Overall, I found the IPS HDR display beautifully bright and viewable from a wide angle, and its 10-point touch performance was responsive. The built-in battery enabled the use of the monitor for a variety of cases, including as a portable, additional computer screen, enlarged monitor for mobile devices/phones, and gaming via the Mini-HDMI interface (ie. XBOX, Nintendo Switch, PS4) without the need to be close to a power source.

  • As a wedding photographer, the built-in battery allows for on-location video and photo editing for a few hours, and/or to display beautiful imagery/videos to potential clients.
  • As an office worker, spreadsheets and reports can be processed easier in landscape or portrait orientation while freeing up the primary display for other things.
  • As a gamer or for media consumption (movies), the large screen can provide hours of entertainment without needing a power source

The biggest issues I have with the product are that it is somewhat heavy and cannot use a single USB-C cable for both charging and playing audio/video. Regardless, this UPerfect monitor is a fairly good buy with its many connectivity options for use with laptops, mobile devices, and gaming systems.
