Kwumsy Screen Keyboard 6

REVIEW – After testing and reviewing several products made by Kwumsy, I am quite familiar with their style and the innovation they work to deliver with each device type. One of their products that I previously tested was the Kwumsy K1 mechanical keyboard that featured a flat small touchscreen monitor built in right above the keyboard. While I liked this keyboard, after a while the inability to raise the monitor to a comfortable viewing angle became somewhat of an issue for me. Recently, I was quite happy to learn that Kwumsy has now offered this Kwumsy K3 Touch-Expanding Screen Keyboard that seems feature-packed and has likely solved my viewing angle issue.

What is it?

The Kwumsy K3 is a Touch-Expanding portable multifunctional split mechanical keyboard with a 13″ high-resolution Touchscreen display. The built-in connectivity includes two USB-A ports and one USB-C port. The keyboard can be connected to other devices via USB-C or USB Type-C cable or HDMI + (2) USB-A connector cable. There is a button to lock the monitor at various levels for eye comfort.

Connecting the  Kwumsy K2 12.6″ Touchscreen Gaming Mechanical Keyboard depends on how you want to use it. In my case, I am using it as a part of my workflow process for my podcast recording. it is used to provide data/media projections. I have the HDMI/USB-A combination cable connected to a Mini PC with the USB-C end connected to the Kwumsy. The only other cable I need is a USC-C power cable.

The next adjustment was to raise the monitor to a level that was comfortable for my use. There is a small button at the side that releases the monitor so that it can be moved to various levels. I did make the mistake once and force the monitor. I could hear the clicks that immediately told me that if I didn’t use the button, the gears which sounded like plastic would wear out or beak rendering this function useless.

This keyboard is plug and play so as soon as I connected it to my Windows 11 mini PC, all functions seemed to work, including the touch function. I like the way the keyboard keys feel, including the positive clicks and feedback that I get from each key. The display is bright and clear, and the touch function is amazingly responsive. I also like that it has a great viewing angle from either side.  In my case, I have it connected as the primary monitor with a video switcher as the second video out, which displays on my small multiview monitor and allows me to go live. It is great that this Kwumsy can be used as a primary or secondary monitor.  Another interesting feature is the ability to customize the keys on the keyboard. While it does not have a number pad, an add-on number pad can be ordered separately.

Here is a quick look at the device in my setup:

What I like

  • The beautiful design is sleek and also feels durable
  • The high-resolution display
  • The nice viewing angles
  • It is plug-and-play at least for MS Windows OS
  • The ability to adjust the viewing level of the monitor
  • It can be used as a primary or secondary monitor
  • The keys feel nice when typing. Nice feedback

What I’d change

  • I wish there was a number pad on the keyboard

Final thoughts

The Kwumsy K3 Touch-Expanding Screen Keyboard is a great upgrade from the K1. The adjustable screen, the really easy plug-and-play capability, and the beautiful touchscreen are some of the things to love about this device. While I wish it had a conventional number pad on the keyboard, that complaint is minor. I am giving this device two thumbs up!!

  2. I purchased the Kwumsy K3 keyboard as part of their Kickstarter campaign. I passed on the original version of the keyboard because I foresaw the kink in my neck of using the flat monitor version.

    When I hook it up to my home computer, it functions well. On my work computer, I couldn’t get the touch screen to work at all, which was disappointing, but not a show stopper.

    I thought I’d be wanting to change out the keycaps and switches, but it actually types quietly (my gamer work friends were disappointed by how quietly it typed) and the key travel is good. I do miss the keypad and the extra enter key found with the keypad.

    The one thing I wish they’d done differently is move the power switch to a more convenient location. It’s in the back of the device, and since I like to power down the monitor between sessions (but leave the computer powered on), it requires me to pick up the keyboard and reach around everything to turn it off. Minor annoyance though.
