How To Play Out On Multiple Screens

This How To will show you how to quickly set up the configuration for rendering on multiple screens with the Ventuz Runtime.

Introduction

You will learn how to configure the Render Setup and what configurations need to be done in your GPU settings.

We will cover the following topics:

• Hardware setup
• Ventuz configuration

General Hardware Setup

In order to show your content with a presentation on two screens you need to setup Mosaic (for nvidia) or eyefinity (for AMD) first.

For a normal consumer GPU these span mode is called a bit different for Nvidia, there it is called Nvidia Surround.

Depending on the generation of GPU, these might be at a different location. If you need more help for those setups visit these pages: [​https://www.amd.com/en/support/kb/faq/dh2-014 AMD Eyefinity. ​Nvidia Surround ​Nvidia Mosaic

Ventuz Configuration

After the span mode is set up according to the manufacturer's manual, we can configure the Render Setup in Ventuz.

Open the Configuration Editor and create a new configuration in the "Layout Configuration for Rendering on Multiple Outputs" category by  clicking the "+" on the right side. Now you can give it a name and after  clicking OK the Layout Configuration Editor opens.

What you will see now is something similar to this.

Now click on the icon marked in the top left to create a new setup. Change the displays per machine to the count you need and hit create. For this example we only have one machine. If you need to learn how to setup a multi-machine cluster, have a look at this how to. This dialog will always override the existing setup.

These screens are freely movable and therefore can be adjusted till they fit the arrangement of your displays.

Notice how there is always this thicker outer wall, which is the whole rendered area. This is important to know because Ventuz will always use the whole rectangle as its rendered area so that for example: if things are moving from left to right and there is a lot of space between those screens, that the object moving respects the free space. Also if you have a lot of the rendered area that is not covered by any screens - these areas are still rendered by the GPU and thus take up performance and GPU memory.

Now save the configuration. The only thing left now is starting your presentation. For testing purposes each Ventuz installation holds a Default presentation, launchable from the start screen of the Ventuz Configuration Editor in the Live Project Management] section. For a more detailed description of the render setup and its possibilities take a look here.

Conclusion

Now it should be possible for you to work with multiple displays in any arrangement. The number of displays also shouldn't make a difference anymore.
