Pros: has a touch-sensitive screen, more pressure sensitivity options and shortcuts, some pen displays come with complimentary software or trials
Cons: can be pricey, screen sizes and tilt features vary, further research required in regard to styluses and monitor specifications
In contrast to their smaller pen tablet counterparts, pen displays have larger HD IPS screens with varying levels of touch sensitivity, making these tablets the most optimal for more serious digital artists. Most industry artists that I personally know either own a Wacom Cintiq or a Huion Kamvas for this reason. Pen displays come with a wide array of options, from shortcuts to HDMI and USB-C plug-ins to an assortment of settings customization and pen sensitivities. Some companies even bundle their pen displays with free trials of digital art software or a watered-down version of some software.
The biggest con in this category is, of course, the price point. Pen displays can range anywhere from $200 USD to $2,000 USD depending on the make, model, and what it comes with. Some pen displays are also more portable than others, but most still require a computer, laptop, or wall outlet to power the device. Styluses can come either battery-free or a need for batteries, and some pen displays are HDMI only. Researching the specifications of each pen display is key to matching your needs. However, these devices tend to be a well-loved game changer for most digital artists who wanted to make the investment and upgrade.
My recommendations in this category:
Best budget/entry-level: GAOMON PD1161 and HUION KAMVAS 13
Mid-tier options: Wacom One Drawing Tablet with Screen, HUION KAMVAS Pro 16, and Wacom Cintiq 16 (the best mid-to-high tier overall for the price!)
The cream of the crop: HUION Kamvas Pro 22 (and also the HUION KAMVAS Pro 20 for a smaller, cheaper option) Wacom Cintiq 22 (there's also the newest Cintiq Pro 24 but at an even steeper price point)
