Macbook Pro to projector issues
We are getting random display issues when connecting the blue VGA(RGB) projector cable to thunderbolt mini adapter (genuine Apple version). We often get three stripes down the projected image. I know we can resolve this with a shut down and restart however in a classroom situation this is not ideal.
Does anyone have experience of this issue and if so did you find a workaround?
The reseller did suggest booting once whilst holding down shift key which then boots into 'safe mode' followed by a restart and we thought that this would resolve it but we are still getting random, maybe 15% of staff, with either the striped image or just a blue screen.
