Question about ViewSonic PJ452 LCD Projector
The projector is about 4-5 years old......for the last 2 years, little blue dots have been appearing around the edges a first then eventually covering most of the screen. the picture is still clear except for the light blue haze from the dots. looks like individual pixels out. i was wondering if it is dust that somehow got dust inside or a part of the inside the projector that needs to be serviced or replaced. also i am wondering if it something that i can do myself if i got replacement parts or if i need to send it in to be serviced.

This is normally caused by a discrepancy between the computer screen resolution and the projector resolution. It could also be related to the computer screen resolution and the aspect ratio of the projector.
Could you please confirm what cable you're using to connect the computer to projector. Could you also please confirm the computer screen resolution and if the projector is set to Auto Source Select along with its Aspect Ratio.
