If the lamp is very old then this could be a problem.
Otherwise an optical part has deteriated due to overheating

take it to a repair shop

It sounds like the cooling air path is being blocked somewhere, the cooling fan is not operating properly or the air filter is already clogged with dust. Remove the air filter and visually inspect it. Bang it on a flat surface with the outside surface facing down. If only a small amount of loose dust falls off, then you have additional cooling problems as I mentioned above and you should return it for warranty repairs or exchange. Operate the projector without the filter and see if the problem returns. If not, and the filter looks ok physically I would insist on an exchange or warranty repair.

Since it is working on a separate LCD monitor, the problem is with the input settings on the projector. Make sure you have the correct RGB/VGA input selected on the projector. Also make sure you are not sending a resolution that is higher than what the projector can handle.
