I see white dots on the projected image, from Optoma GT720 projector.
Its working fine otherwise, and these are visible only on black/dark image.
while playing a movie, you cannot notice it, even though they are there. except in totally dark scenes
This seems to have happened, while moving the projector, there was quite an amount of dust inside, so when i moved this projector un-mounting dust seems to have moved around.
Picture was flickering as well initially, i opened the projector and blew air using air can to resolve this color wheel flickering due to dust.
That solved it. but these white dots still remain.
Anyone faced this issue? any clues and solutions?

Its old, so out of warranty
For me, it looks like, some dust or residue stuck in the light path of the projector
