GAOMON PD2200 pen display review – A 21.5-inch drawing tablet tested with Windows 11, Ubuntu 24.04, Krita software

GAOMON PD2200 pen Display review

Today, we’ll review the GAOMON PD2200 pen display, a 21.5-inch drawing tablet with 1920 x 1080 resolution, and an AP32 stylus with 8192 levels of pressure sensitivity. It allows you to draw and write in the same way as you would with a pen and paper. It can also be used as a standard HDMI monitor and is similar to the smaller, but higher resolution (2560 x 1440) HUION Kamvas Pro 16 (2.5K) we reviewed last April. HUION and GAOMON are different brands, but based on the shipping information, they may be made by the same company… Guangdong Gaomon Technology sent us a sample of the GAOMON PD2200 drawing tablet for review. We will test the device as an external display in Windows 11 and Ubuntu 22.04 and as a drawing tablet using the stylus with Krita open-source software that works fine in both Windows and Linux.
