The question is: does monitor "MONITOR VIEWSONIC 21,5" LED LCD TOUCH TD2220 VGA/DVI" support touchscreen on raspberry pi 4? If you have any prior experiences or educated guesses then please help. I have been googling around. There were some confirmations on the topic but not enough for a bigger buy. As far for contacting the vendor there is stil no respone. I would appreciate any advice. Thank you.

  • The important part of the monitor spec is the "USB HID Touch driver", which is supported in Linux, though the multi-touch may not be supported as well as in Windows. – Dmitry Grigoryev Feb 2 '20 at 19:34

The Viewsonic TD2220 works perfectly via USB as a touch screen with 1920x1080. Source

Write the last Raspbian Buster to your SD-Card and plug the USB cable to the Raspberry Pi, it's also hot-swapped/hot-plugged.

  • @IvanŽ If you install ubuntu or another operating system instead of the raspbian buster, you may need to add some drivers. – M. Rostami Jan 30 '20 at 20:02

    Additonal confirmation sources are still welcome from anyone for anyone in the future too. – Ivan Ž Jan 30 '20 at 20:07
