Question about ASUS ZenScreen MB16AC

No, the ZenScreen MB16AC is neither touch nor pen compatible.
For touch, the ZenScreen MB16AMT is similar in 10-point capacitive touch, built-in battery, and USB-C (DisplayPort USB-C alt mode or DisplayLink USB A/C, like the MB16AC) or micro-HDMI connectivity.

All capacitive touchscreens can work with capacitive styluses, but they are nothing compared to finger use. To write or draw, a real active pen is needed (better resolution than touch, pressure information, etc...), and you have to move to graphic tablets with integrated screen like the Wacom Cintiq 16, or even higher end to have pen+touch. Make sure you know what you want to use the pen for.

Hello No it is not touch sensitive and does not work with a stylus (despite its strong resemblance to an I pad)
But it is very good quality (I use it as a screen for my mac mini when I am out of the office, for a live stream for example).
