Depending on your Company's plan, you will have a certain number of Live Outputs available. If you are a company admin, find your Outputs quota under the Company Usage section.
For this reason, while an Output is disabled, it will show a watermark. You can use this mode to prepare and test your Graphics.
Setting the Output Live
To set it live, open the Graphics Package's remote control. You will find a button to set it live in the top bar.
You will also be able to enable the output from the Project Home.
If you are about to exceed the quota, the system will let you know. In this case, you can Disable another Output or upgrade your plan.
