Hi Suzan,

Thank you for posting in our forum.

It seems that you have 2 issues occurring simultaneously, so in order to assist you further, please check steps below regarding the flickering image and then we will move on to the “pen skipping” issue.

1 – are all the cables connected correctly? (VGA, USB, power cables, etc)
2 – does the image flicker if you disconnect the VGA/HDMI cable from the back of the projector?
3 – does the same issue happen with another laptop/pc?

This query will be logged in our system under case number 00478606 should you require to contact us direct.

Thank you for your cooperation.
