How can I tell if components will hook up to my 3d projector

I think you mean Acer, not Asus?

That projecor does not support HDMI 1.4a 3D. It only works with the NVidia 3D kit, which sends 120 Hz video to the projector, and syncronizes shutter glasses with its own IR-emitter. The glasses come with the NVidia kit, not with the projector.

That excludes the use of the Playstation or a 3D Blu-ray player as the source device for 3D signals.

So, basically, the Acer projector is just a 120 Hz projector, and not so much an actual 3D projector.

Yes, it says it right there on the 3D Blu-ray tab:

"SYSTEM REQUIREMENTS
Just make sure your 3D PC has the following:

* Compatible NVIDIA GeForce GPU
* HDCP-compliant 3D Vision Ready display. Please check the 3D Vision system requirements page for a full list of displays.
* Microsoft® Windows® 7 32-bit or 64-bit
* 2x speed Blu-ray drive
* Blu-ray 3D enabled movie player application *

* NVIDIA has worked with Cyberlink, ArcSoft, Sonic, and Corel to ensure their latest players offer exceptional Blu-ray 3D playback when paired with GeForce GPUs and 3D Vision technology"

As best I can determine your PJ has a native reolution of 720p (1280x720@60Hz) and can not accept any 120fps content, And also AFAIK Nvidia 3d player outputs games in frame sequential 1280x720@60 hz content.

Provide a link I have no idea what it means.

I try to clear alanwest09872's doubts.

Projectors like this accept a 720p@120Hz Frame Sequential format. This means that the left and right images are sent "interleaved" in the stream. Then the projector displays them with the same order: left, right, left, right, at 120Hz.

Recent 3D HDTVs with HDMI 1.4 instead accept a Frame Packing format, where the left and right images are "packed" togheter in a 1920x2205@24Hz format (for 3D Blu-rays). Then the TV "unpacks" the two images and shows them like the projector above.

So the presentation technology is the same, but the input format accepted is different.

3D Blu-ray stand-alone players ouput in the Frame Packing format only (there are exceptions), so you can't watch a 3D blu-ray form a stand-alone player with this projector.

HTPCs are much more flexible. The commercial players (PowerDVD10, TMT3 3D plugin and probably WinDVD too) let you choose the output format. Among others, there is Frame Packing (for 3DTV with HDMI 1.4) and Frame Sequential at 120Hz (nVidia 3D Vision way). With a HTPC, an nVidia compatible graphics card and one of these players you can watch 3D Blu-rays with this projector (in 720p, of course).

If you want to watch 3D mkvs, though, as I understand from your previous posts, you need to check that the software player (and version) you choose plays mkvs. Also, not all kinds of mkvs are played and the support changes at every version.

As for 85Hz, this is used only for 2D. In 3D flicker is unbearable.

We are all waiting for CEDIA in September. It is expected that they will show the new front projectors with HDMI 1.4 there. Expecially waited (at least by me) are 3D Full HD projectors at affordable prices.
