Optoma 3d xl with acer 1210k projector

I own the Optoma 3d-xl and I'm not 100% sure, but I don't think it would work if you don't have a projector with an hdmi input. I would call and talk to optoma tech support and see if it would work using the hdmi to vga adapter. The 3d through vga is meant for computers with 3d software or hardware.

in short...no it will not work. The EID on the player has to "handshake" with the projector, which is not possible with a VGA input, unless your connecting a PC to it. All other set top boxes (ie blu ray players....) will not work.

they are not built in, they are a separate box

Actually, I have a 3d-xl outputting 3d through an hdmi to vga adapter.

The projector is an infocus in146 3d ready dlp. The hdmi port on the projector stopped working about a week before I was going to order my 3d-xl. I took a chance and ordered a Sanoxy hdmi to vga converter (white) off amazon.com for $30 and it passes the 3d signal over the vga input on the projector. Currently running a PS3 and a roku box (wealthtv 3d) with no problems.
I don't know if It's how the projector is made or I just got lucky. Just wanted to let you know that with my set up it is possible.

Anyone have any questions or answers why it works. Feel free to ask.

its amazing all the stuff that's coming out to help people with all kinds of tech get 3D over a projector. Tru3D Now has a HDMI to VGA converter box for 3D. Now with the TRU3D, I'm not sure if it's a stand alone device or you have to buy it then buy like the optoma 3DXL.
Also, there is a product called HDFury4, i believe, that right out of the box hooks to a VGA only projector and is ready for a external 3D blue ray HDMI only port, or whatever. On the down side they will both set you back almost $400. What seems to surprise me the most though, is the amount of people who DON'T !! know about these products. I would expect more people on these forums to know about these products then what already do.. People say flat out, "They don't" when in fact they are dead wrong, lol. But i understand. Most of the community on the AVS 3D section don't deal with the VGA stuff. So, it's cool. I have a viewsonic pjd6211 projector with only a VGA but will be using Nvidia 3D vision.. I would have to admit though. Instead of forking out $300 dollars for these adapters, It would probably be cheaper just to sell the projector you have then take the $300 and put it to a projector that at least has an HDMI 1.3 port then go from there.

when you put the projector in 3D mode while using the optoma 3DXL, does it cut the luman in half as well. I know when using the computer in 3D usage it take the 2500 luman of my projector and shifts into 2x60htz images for the 3D giving 1200 luman output.

Also, which VGA to HDMI converter box did you use??? Can you give a link on amazon for me??

so your saying that the brightness of the projector is pretty much the same rather in 2D mode and 3D mode?? Thats cool. Have you tried 3d on your projector on normal computer setting your refresh rate to 120htz? Curious if it reduces your lumans as well. I just know with my projector that when i switch to 120htz which is needed for 3D with my computer it divides the brightness into 2 60 htz images at 1200 luman each.

Wanted to clarify, by when i asked if the brightness is the same rather in 2D mode or 3D mode, I ment when using the 3DXL.
