I recently replaced a lamp in one of our 4610x projectors (after only ~1 year of service).  Since I bought an aftermarket lamp for far less than what a Dell replacement would cost, I'm now getting the following message imtermittently displayed by the projector:

"Please use an original lamp to ensure safe and optimal working of your projector"

Other than shelling out another $200, is there any way to get rid of this stupid message?
