I agree with Phil.
As long as you do not have to span one source across 2 or 3 projectors, I think a Matrix switcher should do the trick. Look for a 4×4 or 8×4 or 8×8 Matrix Switcher, perhaps from Kramer or Extron (the latter being more expensive).

Sorry to disagree here. According to the specs –
Sharp XR-32X DLP Projector (1024×768, 2500 Lumens, 2,200:1, HDTV Compatible)
its native resolution is only XGA (1024×768). One can feed it lower or higher resolutions, and its internal electronics will accept probably these other resolutions (up to a limit), but it will also internally scale the input to 1024×768 for output. That’s the only resolution the chip will handle – its native resolution.
Essentially, it is pointless to produce material higher than 1024×768 when the projector will only output that resolution. On the other hand, higher res materiial scaled down to a lower res is likely to look sharper, etc…like watching 1920×1080 material on a TV that is 1366×768.
Advice: Do a test.

Doubt if it is the power supply. The usual symptom for lack of power is a sudden re-boot of the computer rather than loss of frame-rates.
One symptom of a graphics card’s GPU slacking is that the video frame-rate would slow down relative to the audio, i.e. audio and video gets out of sync pretty early. Is that the case with your tests?
Haven’t tried Eyefinity cards myself. New territory for most I guess.
The main problem with 2 cards’ outputs would likely be gen-lock between the two, i.e. does whatever is on-screen remain in sync or does it break-up (horizontal or vertical tear depending on your arrangement of the parts relative to the outputs from the 2 discrete cards). Think the player used also matters.
I have tried successfully 4 mpeg-2 playback out of my one desktop with 2 older non-Eyefinity Radeon cards (X-series). Looped them all day and frame-sync remained perfect over the 4 full-screen outputs (2 from each card). I am using a dongled software sold specially for multi-display playback though I was using it beyond its advertised 2 full-screen outputs. Therefore suggest you test more with video playback or something close to what you would be using the 8 outputs for.

Agreed. More often than not, we who do not understand the language being voiced think it is ok when the read sounds corny to the ones being addressed to. A professional read is very different from merely being to speak the language. You and I may speak English but can we get a job as a voice-over talent?
One way to ‘test’ a read is to get a friend of a friend who understands the language to play the role of the intended audience, listen to it and give you his/her honest opinion.

Does your M-audio USB unit have 6 audio outputs and ASIO driver?
If yes, then a software that can use the ASIO driver can send the audio out through the M-audio and you have your six separate audio channels. Obviously the same software should be able to send out one video channel at the same time.
Check out VJ software, depending on Windows or Mac –
MX Wendler
Module 8 (Mac)
Resolume
Archaos
or try demos where available from this list –

does Watchout have a builtin encoder?
No. It has a built-in Elecard MPEG-2 Decoder.
Recommended encoders for Watchout are TMPGEnc or Procoder. Not sure of Telestream.
Another recommendation is to set the encoder to ‘All I-frames’ with ‘Closed GOP’. Walter should be able to confirm this recommendation as he uses Watchout.H264 is not recommended because it is too processor intensive on decoding, and Watchout may be needed to do other things simultaneously whilst the video is running (backgrounds, animated framing, etc). Again, Walter should be able to confirm.

https://www.technovision.com/dv75.html for HD, and
https://www.technovision.com/dv66.html for SDAccording to an email reply from their Director of Sales for an enquiry I made some time ago –
“If playing back multiple files (that have to be in synch) in sequence, the current firmware for the DV75s will allow them to be synchronized via the Ethernet port. One player is designated as the “Server” with the other players as “Clients” each starting their file the same time that the “server” starts it’s file. The DV75, when attached to a network, “pulls” it’s content from a network or internet server – you change the content on the server and the DV75s that are set up to look at that server will automatically change.Otherwise you can also synchronize using the TV66K controller..”
The price of the DV75 is comparable to the Brightsign HD210, so the DV66 should b e cheaper, but “Multiple [DV66] players can be synchronized using SYNCHT1 firmware.”
Happy hunting!

Viewstream 300 for SD video and the 450 for HD are available for multi-sync. A remote controller is optional accessory. Not sure of price though but hopefully cheaper than the Brightsign HD1010.
-
Yea, looks like the more expensive HD1010 is the only one with a GPIO feature that would allow you to hook up a start /stop remote.
If your traveling show does not need manual control, the HD210, via its scripting feature will auto start on power on, loop all day, and to stop, just power off.
Confer with Brightsign support. They seem pretty helpful and responsive. For 12 sets x 3, perhaps they would consider building a start and stop button on the 12 Master units for you.

Sorry forgot another viable alternative – Brightsign CF Players easily synced via Ethernet with their supplied authoring software. Their HD210 is probably your best and cheapest bet.
