Hey there

I just bought a Digital Galaxy Projector 737... http://www.digitalgalaxy.com.cn/

I can't get my PC to recognize it... The projector has two options I can use to connect it... 1 is a monitor cable (VGA i think its called?), and the 2nd is an S-video cable (the circular end with all the pins)... neither seem to do anything, even if i tell the projector to enter that mode...

When I first hooked it up, I turned off my computer, and plugged into the projector via the s-video cable... it worked, but only for a few seconds, then went to no signal...

Now the projector just says "no signal" no matter which cable i use.

Is there something I have to do in terms of telling my computer to send a signal, or should it do it automatically?

thanks!

The projectors are coming in modern days user manual books and templates. So you have to try that or connect 15 pin male monitor connector into project female connector.

yeah for sure...

the manual, however, is a pretty terrible chinese-english translation, and is very unclear....

maybe i should rephrase my question... is it better for me to connect a projector to a PC via the VGA cable, or via the s-video cable? and also, should everything be unplugged before i make any connections, or does not matter?

or were you saying that every projector is different, and that you cannot give a universal answer?

thanks

hey there

im running windows xp home... its not a laptop... i just turn everything off, connect it via VGA cables, and then what? do i have to do a PC equivalent of hitting fn f4 or f7? or should the signal just automatically go to the projector?

also, i have a vga y-splitter... can i plug both my monitor and the projector in at the same time? if so, is there anything different i have to do?

thanks!

hey there

so, ive tried the method you suggested... it works, but only for a couple of minutes... everything is turned off, i turn on the projector, then i boot up my PC (windows xp home, not a laptop)... the image is indeed being projected, but only until it gets to the windows splash screen... then it just loses the signal all of a sudden...

this problem does not occur with either a friend's laptop (i use the same vga connector), or with my Wii (i use video cables)...

any ideas?

thanks

yeah i tried it again... the projector works fine as my PC is booting... but once the windows splash screen is gone, and the windows desktop starts loading, the signal is just lost...

this doesnt seem to suggest a driver problem does it? it doesnt happen with laptops...

do i have to tell windows to send the image to a different monitor? i was reading how with vista, you have to hold the windows key down and hit X or something... but i just have XP... is there a way to do that with XP?

any help would be much appreciated!
