Question about 3M X20 LCD Projector
When I try to use the projector with a Laptop or a Desktop, it is not able to display image, even I tried we different screen resolutions I get the same result.
Only when I connect a S-Video cable or a USB, I´m getting image.
I have restored the equipment to manufacture defaults and the issue persist.

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.

There is a USB cable that came with the Projector ( one end smaller than the other ) The smaller end goes into the back of the Projector and the normal 2.0 USB end into your PC - This enables you to flick through your slides with the standard Projector remote control.
If you do not have such a cable , you could get one from most good PC and AV shops.
Thanks for using Fixya !

Check for corrosion where the bulb sits in. Is there a fuse required. Make sure you handle the buld with cotton gloves (oil from hands not good) Let me know if that works.

reset the settings to factory default through the menu. swap out the cable. depending on your laptop, press function-f4 or function-f7. if still nothing, you may have a main board issue.
