I got a cheap DLP projector from Dell, since I was on a budget and I just needed one that I could play xbox on. I'm pretty happy with it, since it does what I needed it to do, until this problem started happening. At first, a few white dots started showing up here and there. It's annoying when you're watching a movie, but not so much when you're playing a video game, so I barely noticed. However, these little white dots started to multiply all over the screen, and it became *extremely* annoying. Not only that, but these small black dots started showing up everywhere as well. The screen is not usable now. I can't even read text on the menus.
I probably should have called Dell a long time ago, but I've been busy with school and work, etc. I finally called them today, and they are replacing it. My question now is: what could cause this problem? Is it that it's a cheap projector? Could I have done something wrong to cause the issue? Was it just a defective unit? The reason I ask is because I want to know how this can be avoided with the new projector they are sending.
Has anyone else experienced this problem? I should mention that the model is Dell M410HD. Here is what the problem looks like:
BTW, this picture is pretty low quality, and if you guys need some more detailed ones, I can snap a few tonight. Basically, the white dots seem to be present more on the left side of the screen. The black dots are all over the place, and will sometimes spell "DELL" and "DLP" right in the center of the screen. This is normally what you see when you first turn on the projector, and also when you turn off something connected to the projector (like an xbox). Thanks for your help.
