JPC,

This functionality is not built into native RV Player. You would need a third party application to allow RV Player to see multiple monitors as one large display.

Can you recommend a third party app?

I can't recommend one, but they shouldn't be hard to find.

You will also need a video card that supports displaying multiple monitors as one. Matrox makes the cards that we use in house.

Blake, why can i achieve the functionality of extending the desktop across multiple screens with the chrome app but not the native desktop player?

I have the same question as JPC. If it's all Chrome based, why doesn't this work?

Are you actively working on this?

I've also looked for third party apps and cannot find anything that does this. I've tried 4 different display software that don't help at all.

JPC, Do you have the Chrome app spanning a RiseVision presentation across two monitors?
How did you do it?

Glencoe it's spanning across an 8x2 video wall but only with the chrome app player.

This doesn't help at all. My machine supports multiple screens just fine and the Chrome Player spans all three of my screens without issue. The Windows version does not. 

Your documentation states that it must "see all monitors as one" yet shows no way of accomplishing this. I've tried multiple paid and freeware monitor solutions, as well as the built in Drivers and this is not an option in any of them. It can see all three screens fine.

Nor does this answer the previous question as to why the Chrome App can do this without doing anything and the Windows app cannot since it's all based on Chrome. A simple Google search shows many results on making Java apps span multiple screen, so I am at a loss as to why this is an issue.

Looking for additional information on this.

In order for Rise Windows/Linux Player to be displayed across multiple screens, your video card must support spanning. This means that if you maximize a window, it will span across all displays, not just maximize to one window.

This is something that's being considered for future releases of Rise Player. At this time, it only works with video cards that do support spanning.

This seems to be a 3rd party NVidia/ATI thing, as the only reference I can find of this type of spanning is an old MS Support article "The last version to have this capability was Windows XP."
(http://answers.microsoft.com/en-us/windows/forum/windows_7-desktop/spanning-the-desktop-horizontally...)

This unit spans 3 monitors fine using Extended Desktop. I can manually span a window across all three screens, and the Chrome App does it automatically. So it still stands to reason that if the Chrome App does this, and Windows allows it, than there is no reason the Windows app can't. I also find it strange that this is just 'being considered and isn't a top priority at a time when Video Walls are all the rage.

As an FYI, I also tried 4 different 3rd party softwares last week and none of them support this feature either (As you mentioned earlier in this post about 3rd party software, so if you know of any, please let me know as this is a must have feature going forward).

The typical way to do things like video walls, in software, is to use Watchout or something similar. While I'm sure there's people making it work in Rise Vision I wouldn't put my name on that when I think of all the ways it can go wrong (displays re-ordering, EDID, frame sync, bezel comp, etc.).

But, since we're talking about Rise Vision and it's really only set up to do single display applications, a display wall requires some extra hardware to make it work correctly/reliably. My recommendation is a display wall controller and is what we've used when we tested this idea for a project last year. Datapath makes the x4 which supports input resolutions up to 4000x4000 on dual-link DVI-D. The display outputs will each be a portion of the main input, can be different resolutions, are freely configurable and will do bezel comp and such. Once you have it setup you'll know the bezel mask and can make a template in RV to show you where to put the content if you want it on a discreet display or what will be masked out if it's spanning multiple displays. 

Hope that helps!

Hey Robert,
Thanks for the additional information. I will take a look at Watchout and Datapath to see if there is something that will fit with our setups.

A single Watchout license is $3k and you'll need a pretty powerful computer to run it on. Also it's not "cloud" so updates and such are a lot more work. If you're using it for static content or things that change infrequently though, it's really nice. We use it for live events but not digital signage. Also it's timeline based, not list or cue-stack based so your workflow will be quite different. 

I can't speak highly enough on the Datapath stuff though. You can get the x4 from B&H for about $1k and their setup software does all the hard math for you!

More than one monitor is a key capability. Tight packaging is a given in many applications. 

We make storefront mounting systems for signage monitors and our demos (picture of one attached 1080x3840 mode)  have had great success with Rise Vision on Intel NUC with Intel 4400 Graphics running Win7 and Matrox DualHead2Go Digital SE version connected to NUC's DisplayPort. Works perfectly in 1080x3840 Two High Portrait or 2160x1980 Two High Landscape.

We expect similar results with 3 Monitors and Matrox TripleHEad2Go Digital SE, because the Matrox driver and configuration software presents the combined monitors as a single device. I don't expect that to work in 3 wide x 1920 mode because that would exceed the NUC's limit, but it should work fine in 3 high HD landscape mode.

Not recommended practice, but If you unplug or power down one monitor while running, the Matrox system just keeps running and resizes on the fly, plug it back in and you're fixed.

These Matrox products only support Windows, not Linux. 

We had some success with Rise on 2 monitors using Linux, but Rise Vision player back then wasn't as solid and reliable so we headed to WIndows 7 and Matrox which has worked perfectly. 

The NUC we use officially supports up to 3 Monitors across HDMI and DisplayPort, but no configuration will ever present as a single monitor display to RiseVision. It's a Windows limitation, apps will maximize to fill one monitor only.

As another easy and cheap trick, the LG signage monitors here have a DVI output that we can use that to feed the two monitors on the other side, so long as both sides have same image. So, within cable reach one little NUC can feed 6 monitors (2 identical displays of 3 monitors) with a TripleHead2Go Digital SE.

We have yet to find a low or reasonable cost tiny physical footprint box that can handle 2x2 or 3x3 arrays.

On larger arrays, we've looked casually at Userful but haven't yet tried it. Simpler cabling and one i7 PC connected to a bunch of low cost clients by Ethernet could be a low cost option to larger arrays and Intel NUC comes in an i7 Flavor.

Anyone have experience with a solution for Multiple monitors on Chromeboxes?

Having used the Matrix 2Go products before in a live environment and been burned, I've shied away from them otherwise. Glad you've had a positive experience! I think they work on non-Windows platforms but the drivers to configure and manage them don't. I could be wrong. We tried them on Mac and Windows PC only. 

My posts above speak about the solution that's worked best regardless of platform and that's a display wall controller. What your computer (or Chromebox) see is one monitor/display and the controller divides up the outputs as necessary to the correct outputs, handles bezel comp, geometric correction, etc. 

When we tested it, we used it with a Chromebox and it worked great. We were only using 1920x1080 to drive a 2x2 and since it was a distance from the viewers and our content producer wasn't making better than 1080p content, the pixel count was a non issue for us. If you need better, the larger Chromeboxes can, I believe, drive 4k.

I ordered a Matrox2Go and couldn't get it working and had to have it replaced within 3 days as it wouldn't update Firmware (Did over an hour with support too). I'm not even trying to get a video wall going, just 3 displays side by side without requiring 3 players.

I am currently using  a StarTech 3 Port splitter via DisplayPort using Asus UN42 MiniVivo (It's like the Intel NUC but a bit cheaper).

As mentioned, the Chrome Player spans across the 3 displays automatically with this setup, but it's problematic (It's problematic with one display on other Asus and Intel NUC's we have) so I switched back to the Windows Player, but it only displays on one screen.

Thanks, There's a significant price difference but I'll definitely look at the DataPath solution, especially that it can manage bezel offsets which the Matrox 2Go doesn't do. If they take 4K in they should drive 4x HD signage displays with no loss of resolution.

The Matrox products have been solid for us, granted not live in 24/7 real world use but we run them 16 hours a day here in our demo shop which lacks AC and runs hot in summer. We flipped to a Linux version to test, and once configured on  Windows System, the 2Go products seem to be able to move to Linux or another machine and retain their settings and present to PC as a single monitor as you set up on PC. If something changes or fails, you'd be screwed to fix it and then need a Windows system to reconfigure the array setting. Much too risky for my blood, if the manufacturer doesn't support it, don't do it.

You should take a look at a product named MonitorsAnyWhere. It has a new capability to run Video Walls exactly as you describe in a fraction of the price of all other solutions in the market and it's Windows based.
