Lower the resolution on the laptop display properties to 800 x 640 and try that to test.
If successful, increase the resolution 1 step to 1024 x 768. If again success ful, try 1 more step in resolution to 1280 x 1024 and so on.

I have a Optoma EP721. It now projects verticle lines on the screen background. How do you eliminate the verticle lines ?

It sounds like you have a projector which is in need of professional repair. You should eliminate source material problems first though by checking the projector with alternative input sources, ensuring that you also check the cables, and various inputs on the projector.
If the lines are present on all the inputs then the fault is internal to the projector. This will require professional repair. The first point of contact should be Optoma at (UK) or (USA). They should be able to give you an idea of ow much it may potentially cost to have your projector repaired and (most importantly) check whether it is under warranty. Most Optoma projectors ship with 3 year warranties these days.
