Bosto Kingtee 22U Review, a mini Pen Display Tablet


Bosto Kingtee 22U Review In Few Words (Mini Review)

Bosto Kingtee 22U is a generally good pen display, which provides you a Cintiq-like experience for drawing directly on the screen. It may not be the best pen display I reviewed yet, giving how it doesn’t support Mac officially, but you could use it on a Mac & Linux using the 3rd party firmware.

If we chose to ignore these two problems above, you get a good package out of Bosto Kingtee 22U, like a relatively big screen with HD resolution, and good pressure sensitivity.

Please bear in mind that this review is based on research, and that I don’t own Bosto Kingtee 22U myself. I hope you find my findings in this review useful.

This is my first time reviewing a pen display tablet from Bosto, another company that produces Cintiq alternatives. From the first look, Bosto Kingtee 22U looks similar to the other pen displays I reviewed before, with a flat display with no hotkeys on it, and a stand that can be tilted backward & forward. These pen displays gives you a good tool to draw directly on the screen, they may not have the bell & whistles of the more expensive Cinitq.

Bosto Kingtee 22U mini-Sreen

Bosto Kingtee 22U provides a 21.5 inches display with a full HD 1920 X 1080 resolution, which is enough to drawing for most people. The pressure sensitivity is 2048, which is the typical you see in most drawing graphics tablets nowadays.

In case you are new to graphics tablets, pressure sensitivity allows you to draw thicker lines by pressing more with the pen, it is an important feature for drawing, besides being able to draw with the pen, but you shouldn’t stress much over the amount of pressure sensitivity your device has, as anything above 1024 is good (512 is good for some people).

Bosto Kingtee 22U has no hotkeys on it, so you will need to keep your keyboard besides you while you are drawing.

By the time of writing this article, Bosto Kingtee 22U works with Windows only, as there is no Mac drivers in the website, so it is not an option in case you are a Mac user. Some of the other Bosto pen displays have a Mac driver, so I wonder why this one doesn’t have one. According to the admin in the support forum, there is third-party firmware update for it, which you could access in this link. 

The display buttons are at the button of the display, which mean you will need to lift up the display to use them, either to calibrate the colors or to power it on/off.


You can connects Bosto Kingtee 22U to your computer via one of the VGA, DVI & HDMI available in it, which makes it compatible with all sorts of monitor. It doesn’t support Mac’s mini Displayport out of the box, but since there is no Mac driver for it yet, this is not an issue. Thanks to the placement of the display ports, you can’t lay Bosto Kingtee 22U on a perfectly flat position.

Now let’s talk about drawing with Bosto Kingtee 22U, to create strokes with the pen, you will need to press in the range of 0.5 gram to 1 gram for the stroke to appear, something that’s known as initial activation force (IAF), which needs to be low enough to draw comfortably. The IAF in this tablet is probably as good as it gets for any brand of pen display tablet. You can also test Bosto Kingtee 22U with the ruler test to see if the final lines will have jitters, and you won’t find that.


The pen that comes with Bosto Kingtee 22U is charged via the USB cable, since you need to plug the charging cable in the back of the pen, it has no eraser at the back of it.

Bosto Kingtee 22U works with many art applications, like Photoshop, Illustrator, Sketchbook Pro, Manga Studio & Corel Painter. There is a good chance it will work with more art applications too.

The User Manual

The manual that comes with Bosto Kingtee 22U is in both English & Chinese. I don’t speak Chinese, but the English in is bad, something I have seen before in multiple Chinese products before, it is okay to read, but it would have been better to hire someone to write a better manual.

Possible Problem

In case some parts of Bosto Kingtee 22U drawing is smooth while others are not, it is advisable you clean the dust off your tablet, just like it is explained in this thread

And Finally

Generally speaking, Bosto Kingtee 22U is one worthy pen display to check if you are looking for a Cintiq alternative, but I also advice you to check out the other Cintiq alternatives I reviewed to see the other options, which also provide similar options to Bosto Kingtee 22U, as well as Mac drivers too.

I hope you liked my Bosto Kingtee 22U review, and see you again in another review. ^^

I am an anime artist, and huge fan of digital art. I love drawing with pencils too. But I rarely do that anymore nowadays. Since some aspects of digital art can be tricky, I try my best to explain the concepts as easily as possible.


  1. Thank you for your informative review SweetMonia.

    You mention an initial activation force of 0.5 – 1 gram, and I would like to add that this is probably as good as it gets for any brand of pen display tablet. In fact, Bosto’s patented pen input technology is one of the great advantages of this tablet. The 22U mini is also well known for its proven stability and solid factory-backed support.

    As a matter of interest, the third-party firmware update you mention unlocks the full potential of the 22U mini for Windows, Mac and Linux. More information about this can be found on the Bosto User Group forums at

    1. You are welcome, dear Jeff,

      I added that as you requested, it is interesting to see support for Linux as well. As not much hardware support it from what I know (Wacom has had unofficial Linux support for some time now).
