Video Wall Processors and 4x 4K on Zotac Mini

Hardware
1

Hi All,

I’am currently planning a project in the US, but aim not from the US :).
And for the project I’am not using the regular hardware I would regularly do, since I don’t have access or know any distributors.

So I would like to ask you, if somebody has some experience with one of the following video wall processors:

I found them on amazon, but yeah they look kind a dodgy.
Maybe someone knows a better one in the same price range, available from a reseller in the US?
It doesn’t need to be a Datapath. Just needs to split the video signal into 4.
No warping, edgeblending etc. needed.

Another question is, if somebody has already decoded 4x 4K Streams (Hap or another GPU codec) on one of those:

Thank you!

I’m also curious about those cheap video wall processors. It seems the first one you posted supports 4k30hz input so I would go with this and ignore the others as they only support 1080p input. Could you report back if you end up trying it? It seems like a good deal if it works as claimed.

And as for your questions about the ZOTAC, TD has no problem to read 4 different 4k HAP videos at once in real time. HAP is really light on your CPU but the files are large so it relies on fast read rate on your SSD. Even HAPQ works fine but if you need 60fps while reading 4 different HAPQ files, your SSD might be a bottleneck. So, ideally you need a really fast ssd (nvme 970 evo or pro) or, a very simple alternative would be to read from 2, 3 or 4 different drives. 4k HAP is pretty light, I’m pretty sure you can read 2 of them on any SSD (even SATA) so if you split your load on two SSDs you should be fine.

Dig you try out any of the video wall controllers?

Nope never tried one of those.
