onis_uk · 13-03-2007, 7:08 PM

right i just bought a VGA cable for my Xbox 360 and was hoping to plug the VGA into the digital port using this adapotr because it has a stange Dvi m1-DA port on it .... http://cgi.ebay.co.uk/ws/eBayISAPI.d...4295&rd=1&rd=1

but im not getting a signal ?! is this not going to work ?!?

cheers dom

Nope. You infocus most likely handles DVI-D D=digital, VGA is analogue. Has it got a Component input?

M1-DA can do both Digital and Analogue (DA).

Is there a analogue button on the PJ remote for the M1-DA connection?

thats what i thought it could do both !!! no it has an auto image button but it doesnt seem to do anything lol im at a loss

Those adapters are for plugging into the back of a PC to change the gender from DVI to VGA, i.e. split off the analogue output, and I would guess they are not designed to work the other way round. Just found this http://www.keene.co.uk/electronics/m...?mycode=KAM1DA

They are for Infocus PJ's and anything else with a M1-DA socket. Even though a DVI signal will work through them. They are not DVI sockets (they are longer and have different pins). It is possible to get adapters for which way you want. I have seen VGA to M1-DA on a Infocus IN72 PJ using a laptop.

To Andy98765....this connector that i have bought states on the ad that its for my pj and will give me a VGA input ?!?!
the lead you link to is the one that comes with the pj ...i guess i could just use a gender bender and join my vga cable to it but i just dont see why my cable adaptor doesnt work ?!?

I use one a similar adaptor on my 4805 from my scaler over 9m of VGA cable and it gives a great picture. Are you outputting RGB from the source?

I'm sure the advice is well meant; but incorrect. Your adaptor looks OK to me. This connection on this projector doesn't take well to double adaptation either - although thats more a HDMI - DVI thing. If your x-box allows try outputting a standard computer resolution eg. 640x480 and see if it can lock to that. And don't forget the old chestnut of trying a different cable.

Righty ok ive now got my vga signal coming out of my xbox into the vga y-lead and off to my pj and off to my lcd screen but when i plug in the lcd screen into the splitter both pics come on fine but it just dims the picture slightly?!?! how can i stop this from happening ?!

Either find something to amplify the signal or alter the settings the 4805's menus to compensate. What was the solution to your original problem?

onis_uk · 20-03-2007, 7:02 PM

well im not to sure really ?! the adaptor i bought just didnt work. i ended up using the lead that comes with the pj for connecting it to a pc, and just used a male to male VGA joiner and all works ok ! cheers lads...

a VGA amp...sounds expensive ?!
