We are considering a Sony 4k projector for our home theater. There is a question about how you could split 4 1080p video sources to display on the device.

Does anyone have any advice on where to find these kinds of display processors?

You mean like 4 different feeds in a quad split? There are plenty of units that do this for a 1080p screen, that is cut it up into four 960x540 pictures, or more, but a 4K unit is probably still rare at this time.

And be careful with HDCP compliance. Commercial gear often does not support HDCP as it's not needed in those applications.

Can you go with a 1920x1080 units and just let the projector upscale it? Some quality loss but it should still be quite good.

Check www.extron.com.

Also for 1080P products, www.miranda.com, www.evertz.com, www.sierravideo.com Note these are HDSDI based broadcast units.

The generic industry name for these devices is a "video wall processor".

very useful links thanks.

Also I believe the OP is talking about the consumer grade VW-1000 from Sony. There are a few threads on the forum about it and the pj is now in the hands of a few owners.

the idea is to display 4 1080p video streams on a 4k projector with no loss of video quality. if it's a 1080p upscaling to 4k, the idea of getting the 4k projector over a 1080p projector becomes irrelevant.

So where are the 4k sources/media for this?

If your steaming 4 1080p sources 1/4 would have to be zoomed loosing native resolution. What your asking makes no sense.
the only benefit of a 4k PJ is if you have a native 4k source.

EDIT, Unless you want to put 4 different 1080p sources to the PJ having a quad screen. Then you want a TV-One unit. they make a unit for that.

TV-One also makes quad units.

How much are 4k PJ's anyhow these days?

Perhaps he wants to watch four different games at the same time in full resolution? This is no doubt going to be an extremely expensive system but hey, if you can afford it......

The TVone units only output up to 1920x1200. To do 4K you would need 4096x2048 (or 4096x3112). This is not commen place yet and will be very expensive if you can even find such a unit. Also you will need multiple DVI or HDMI feeds to carry the output signal. And again the box is going to have to be HDCP compliant if fed by consumer sources such as DBS receivers and Bluray.
