I need a video card that will allow me to play the same video, open in four different media players each one playing in one of four screens.

So, 4 screens. One video playing per screen. The video is the same in all four screens and it is a 2.2GB file.

We currently "recycling a FirePro W9100" that we got from one of our retired servers. However, the videos don't play 100% smooth. They are playable and acceptable, yes. However, It could definitely be a bit smoother.

Which video card would be able to get the job done? I know the FirePro is meant for server/workstation purposes, but I'm surprised even with 320Gb memory bandwidth and 16GB of video RAM, it is struggling.

Any suggestions? and yes I did look at the GTX 1080, but I want to make sure this will work before proceeding.

what type of media players? why not stream wifi to media players? or connect usb to them? What resolution are you going to be running as well. Almost any of the new video cards out can run multi monitors. Most I had connected to my 390 8gb card was 3 monitors and I still had connection for 1 one more.

If its video outputs you need i recall a 7870ghz with 6 mini dp's.

But to me it see s like your asking to play 4 separate instances of a video player on 4 screen simaltaneously. Which any card can handle fine , i cant imagine any card in the last 5 years not handling it.

If a W9100 can't do it...you're going to need multiple graphics cards:
http://www.anandtech.com/show/7901/amd-announces-firepro-w9100

That's basically a 290X. Maybe 295X2?


Wait a minute. Have you opened Task Manager to check the CPU load and Radeon Settings -> Gaming -> Global Settings -> Global OverDrive AMD Radeon (TM) FirePro W9100 to check the GPU load?

The GPU might only be decoding one of the streams (or none) and the bottleneck is actually the CPU. If the bottleneck is the CPU, you might try a different media player that can make use of hardware rendering offloading it to the GPU.


What operating system is this on? I'll just put it out there that most media players associate to the GPU they open on. If you drag the window to another monitor handled by another GPU, it will noticeably lag until it is dragged back to the GPU that is rendering it. A lot of media players don't transition between GPUs on the fly. That's probably not the problem in your case because it sounds like you only have one GPU.


I don't think NVIDIA cards support 4 screens at once without multiple cards. In fact, I think you have the fastest card on the market that can do 6 displays at once without using a DisplayPort MST hub.

Something isnt right, i know for a fact, lesser gpu's can run 4 media players.i thimk your correct in thinking theres an issue.unless im missing something here, maybe im not getting what is being discussed by the op.

Almost any of the new video cards out can run multi monitors. Most I had connected to my 390 8gb card was 3 monitors and I still had connection for 1 one more.

Im using Intuilab Composer for a touch-enabled project. 5 screens, one is a computer display with touch screen and 4 TVs to show the rest of the content. Each screen runs at 1080p. The W9100 can connect up to 6 screens.

If its video outputs you need i recall a 7870ghz with 6 mini dp's.

But to me it see s like your asking to play 4 separate instances of a video player on 4 screen simaltaneously. Which any card can handle fine , i cant imagine any card in the last 5 years not handling it.

I only need 5 outputs so the W9100 does fine with that. Your second sentence is correct. I also expected the same, after reading all of the answers here, I'm starting to suspect it might be the Intuit Player efficiency at rendering content (in this case, four videos playing simultaneously)

The CPU load is fine. I believe it goes to 40% last time I checked. I could never see the GPU load. The drivers it uses are different from Radeon (they are not even Crimson yet). And utilities I downloaded to check usage could not find/didnt support the W9100 (even AMD's own utility).

The CPU is a 6700K. I doubt it is the CPU. The computer is a Z170 and has 16GB of DDR4 RAM. I truly doubt this is coming from the CPU. This is on a Windows 10 machine (fully updated). I only have one video card.

Something isnt right, i know for a fact, lesser gpu's can run 4 media players.i thimk your correct in thinking theres an issue.unless im missing something here, maybe im not getting what is being discussed by the op.

Like I said, even before your replies, I suspected the same. If I open the video (which is a 2.2GB file) on WMP, it plays smooth and fine (on one screen). I really dont see how, even by playing it four times, simultaneously, could cause a $3000 card to "choke".

Should I bother to contact Intuilab at this point?

Why would you want to run 4 instances of the same video instead of running it once and cloning it across all 4 screens? With cloning, you could run the video on lowest end card that has enough outputs...

I cannot do cloning because my project can display different content on each screen. Cloning screens would not allow me to do this. The screen configuration has to be set to expand.

Not even with virtual desktops that you then send to different screens? I think it's possible to even send same virtual desktop to different outputs of your choice.

Im not sure how Intuilab Player would react to that. I know that I have to have it on expand so that the project, which is at 5760x3240, just expands across all screens.

I can't recall what exactly the load was, but just to double-check, ill go ahead and verify that once again.

One question, what does a video require (in terms of video card specs) to play properly? is VRAM the most important aspect? memory bandwidth? memory bus size?

since video is usually passed to the GPU for the actual encoding work it would be the GPU itself.

One question, what does a video require (in terms of video card specs) to play properly? is VRAM the most important aspect? memory bandwidth? memory bus size?
That might be where the bottleneck is. GCN 1.1 has a single Video Coding Engine (encodes H.264/AVC) and one Unified Video Decoder (decodes MPEG2, MPEG4, H.264, VC1).

UVD can handle up to 10 streams but only if it's one of the formats it can handle and they're using it...

Should I bother to contact Intuilab at this point?
...perhaps. We really need to know what kind of video encoding they're using and whether or not they're using the UVD. There might be a setting somewhere that allows you to tell it to use AMD's encoder and decoder hugely improving performance. Assuming nothing else is bottlenecking and the card is being overwhelmed, I think they might have some insight into fixing it.


Then again, you might be asking for more than a W9100 can deliver. I think you'd be better off with 5 single-slot graphics cards. The problem is that the single slot cards available on the market are extremely weak (384 shaders versus 2816) so that's a non-solution...at least until Polaris 11 comes out.


I'd try sticking a 280/290/380/390 card in there with the W9100 moving two of the displays to the second card. Might take care of it.

I would've thought it would be like a HDD bottleneck with the amount of data being used.. I'm probably wrong but its worth a note.

I thought the same and wrote about it...but I apparently deleted it...

Disk activity (HDD/SDD) can be seen via the Task Manager. While you're at it, should check RAM usage too.


Edit: Also, see these:
http://support.intuilab.com/kb/faq/minimum-software-and-hardware-requirements
http://support.intuilab.com/kb/how-to/optimize-performance

Edit: Make sure to use "Performance" Power Plan.

It says "On Windows, use WMV codecs whenever possible as they benefit from hardware acceleration." WMV 9 is aka VC-1 which has been supported since UVD's original release.

Uh, "Try to avoid playing more than one video simultaneously as this can radically improve performance."

The wiki article for UVD mentions UVD 2.2 explicitly as allowing two VC-1 streams simultaneously. The "10 streams" I cited before...here's the full quote: "Multiple streaming support with efficient context switching (up to 10 streams)." UVD can switch between 10 streams simultaneously but that in no way guarantees the card is capable of decoding them all. The current version of UVD is 6 so I don't know if the previous quote is still relevant or not.


I think if GPU-Z says the GPU is loaded to 100%, either you need to stop doing so many simultaneous streams or you need more cards. Even though a 290X/390X costs 10% of a W9100, it has the same hardware resources (2816 shaders) as far as VCE and UVD are concerned. Two 290X/390X would be better than one W9100 for this.

Interesting enough, after experiencing so many crashes on Windows 10 and Intuilab not giving any clear answers, I decided to downgrade the machine to Windows 8.1 (which they seem to have always favored).

The videos run a lot (at least 25%) smoother.

Not sure whether it is something in the Windows Kernel, or driver maturity. When I selected W8.1 drivers on the AMD site, it showed me the exact same file I got for W10.

I am now working on event viewer errors that show up every time I play videos in my Intuiface Composer projects. Seem to be related to performance counters (.Net framework). W10 showed them and now W8.1 shows them as well. Very annoying.

I bought a geforce 1080, and things are actually worse.

Not sure what is going on here.

I bought a geforce 1080, and things are actually worse.

Not sure what is going on here.
Not surprising. AMD has a lot more decoding hardware on-chip than NVIDIA. GTX 9## and 10XX cards are designed pretty much explicitly for DX11 gaming.

Hardware decoding of video tends to look like butt from what i have seen. Just Like Encoding less you run 20+mbit looks crappy.

With CPU you have, should use that to decode instead of gpu. Does though sound like something else is going on as it should be no problem for card to decode stuff.

The system has a 6700K. I even overclocked the CPU to 4.7Ghz in Windows, but barely made a difference. At stock speed, it only goes up to 40% usage.

Could it be the way Intuilab's software handles video playback? Maybe video is decoded as video-in-a-container that is not considered a video file anymore? (kinda like you can play games and do DirectX or Software).

Interesting enough, when I make the video play on one screen only, it plays smooth. The problem arises as soon as I set the video to play maximized to 4 screens. Seems like as soon as the video touches two or more screens, lag (stuttering) comes in.

As I said before, your solution is multiple cards. If you absolutely must get by with one card, consider the Radeon Pro Duo (dual Fury basically). I don't know if even the Radeon Pro Duo would be adequate though.

Yes, using multiple video cards was suggested above. Still didn't work properly. As a matter of fact, I tried 3 different escenarios (btw, the system now has 6 screens instead of 5)

Geforce 1060 + 1060 (no sli).
Video was divided half and half on each card. Playback was horrible.
I then did playback on one card (four screens) and the remaining two screens with nothing on them on the second card. This was a bit better.

Geforce 1080 + 1060 (four screens playing the video on the 1080 and the remaining two screens with no content on the 1060, no videos).
No performance gain whatsoever compared to the 1060 + 1060.

Right now I have it running 1060(4 screens)+1060(2 screens). I feel like the Radeon was doing a smoother job.

My next attempt will be coding the videos with different codecs (currently using handbrake, h.264, x264). Will try x265 and see if that helps.

I do need to mention the software used to crash every now and then with the Radeon so at least the Geforce gave (so far) full stability. If I could get the video to play 15% smoother, I would be satisfied.

This'll turn into one of those dual 18-core Xeon builds with Titans in it thing. I smell it.

Maybe try FFMPEG. You could run one on Intel QuickSync and you can try two NVENCODEs on each of those two cards (I think NVIDIA only allows two per card). That should reasonably get you 5 streams.
