Hi Sue, On your first concern, a possible reason for the 'Sync is out of range' is because your laptop's resolution is just too high for the projector to handle. You may have to manually lower down your screen resolution (right click on a clear area of your desktop, click on properties, settings tab, move bar of screen resolution towards the left). Try different settings that will give you best performance without the projector rejecting the input signal. Am not sure about your second concern though, offhand your description sounds like video noise. You may have to check that your connectors are firmly plugged in. A longshot is to remove any possible source of interference like wireless phones including your mobile, WiFi AP and the likes. Perhaps you give the first suggestion a try and see if the purple dots disappear when you have the projector running ok. Further you may have to reset your projector if it's got one. Normally it's a small button clearly marked RESET somewhere at the rear of the unit. Hope this works out for you. Pls comment/post back should you need further information. Good luck and kind regards.

I have purchased an used MP7630 projector. How do you start running an MP7630 projector. Do I need software for it as well the leads.

You should just require the leads as when you plug your pc into it if the resolution is set correctly, will produce a picture.

clean the dust out of it with canned air and make sure the fans all spin. the dust keeps in the heat that the projector is trying to expel.

You will need to have a dvi to vga converter. If you have a Macbook, it is a mini dvi to vga. You can get this adapter direct from Apple for about $20. A wireless connection is not available with this model projector.
