I bought BenQ MP670 Projector second hand for 100 euro.So my problem is that when iI connected my laptop with my projector via HDMI cable, I got no sound.It is not the cable,I use it to connect my laptop with my plasma TV. And with the projector the thing is that when I turn it on or off it makes a clear and loud sound.So it's not the speakears.I tried different set ups from my laptop to forbid the device which will produce the sound.I went through all of the possible options,because who knows... So anyone with an idea?

please try to switch your pc on first and then your projector-use fn(key) in conjunction with f4 or f5 or f6 or f7.

SOURCE: projector says out of range

The native resolution on the 6100 is 800x600. I have had it recognize 640x480 and 1024x768 though. Check your computer to make sure the resolution is 800x600. Also set the refresh rate at 60htz, if the refresh is too high it can give out of range errors.

Mine needed a "fan module" replaced. The part number is 60.J8613.011.

Cost was $60, plus $100 for labour.

go into the menu and reset the settings to factory default. after that, select computer again and see if it recognizes it. you may need to change the resolution to match the laptop.
