On your PC, there are two ways to set up the HDMI output to your Roland video switcher's input: Duplicate and Extend.
- Duplicate creates a copy of your Desktop, including your Taskbar. Your mouse will appear on both screens.
- Extend creates a clean desktop, and you can move your mouse between the two.
- These can be further customized in your Display Settings.
When you connect the computer's HDMI output to an input on your switcher, the computer will treat the switcher as an additional display, and it may require additional configuration.
Windows 10 will remember your display settings across multiple configurations, so when you connect a different video input or display, it will use the settings previously used with it.
If you choose Extend, you can customize the resolution of the extended display, and have it match the output resolution of your switcher.
For example:
- If your switcher outputs 1080P or 1080i, set the Extended display's resolution to 1920x1080.
- If your switcher outputs 720P, set the Extended display's resolution to 1280x720.
Additionally, if you use an HDMI splitter to duplicate your signal, your computer will see the splitter as an additional display, and not the switcher's input. And if this is your first time connecting that computer's HDMI output to a splitter or switcher input, you may need to adjust the resolution setting as mentioned above.
