It is possible to return a teleprompt to your ST500 and ST55 contributors using Autocue and NDI.
Update 07/23: The free version of Autocue QStart has now been deprecated. If you already have the software you can continue to use it but if you're downloading for the first time, you will not be able to license it without paying a fee.
If you are still looking for free Teleprompting software, we would recommend Imaginary Teleprompter which can be downloaded from here.
The process for adding Imaginary Teleprompter into your workflow is the same as the Autocue Qstart process so follow the steps below.
Autocue still offer prompting solutions which can be found on their website if you are interested.
The manual for QStart can be found here which shows you how to register, configure your output and prepare your text.
You'll need to have NDI Tools downloaded too. Which you can find here...https://www.ndi.tv/tools/
Once that's downloaded, open NDI Screen Capture.
This will enable your display as an NDI source to pull into Quicklink Studio.
Now on the Quicklink control panel, select NDI Receiver as the Input and select the appropriate display (the one with QStart on).
Make sure QStart is maximised on that display and you should see it in More Features.
Remember to press Begin Prompting on QStart to make it full screen.
You now have your teleprompt available as an NDI source.
