Dav B Try changing the laptop resolution to 1024 x 768 or 800 x 600 and check the refresh rate .
DBadhen Posted April 4, 2017 Author Posted April 4, 2017 Projector model is an epsom eb485i , i think , and i tried changing the resolution , starting with the lowest , and it does it again , and ive also learnt yesterday a replacement laptop does the same thing , so its something to do with the board or projector.
Grey-gear Posted April 4, 2017 Posted April 4, 2017 (edited) Does the projector have a different type of connection (HDMI, etc.) you can try? If the projector is connected via a wall socket (wires in the walls running to the projector) you could try plugging a VGA cable directly into the project from the laptop. Does the laptop do the same thing with a different projector? Edited April 4, 2017 by Grey-gear changed first question after rereading the first post
DBadhen Posted April 4, 2017 Author Posted April 4, 2017 tried new VGA as well , will also try a hdmi see if that fixes it ,its a primary school i support , half a day a week, so when I'm in next i will try direct connection , barring that ringing smart . 1
Mic_Impero Posted April 6, 2017 Posted April 6, 2017 Ground loop? Does it happen when laptop is running on battery? If so and you can, try a different breaker or buy a VGA ground loop isolater to cure
