My monitors are not displaying after waking my computer from sleep. Why is this happening?

Sleep and hibernation may lead to some problems in Windows 7-10. Windows 11 allows the operating system to remember window locations and fixes rearrangement issues. We recommend using sleep less frequently if you're not using Windows 11.

My window locations or display arrangement have changed. How can I fix this?

If you can't upgrade to Windows 11, set the input of each display to HDMI. Avoid using Auto. If more changes are needed, use Display Settings to arrange the displays. Limit the use of sleep.

Why can't I get all of my displays working?

Update your video driver and make sure you're using a supported OS. Check with your computer or video card manufacturer to make sure your GPU supports MST and the number of displays you need.

Can I use an MST hub connected to my laptop docking station?

We don't recommend it. We suggest using USB video adapters if you need more monitors connected to your docking station. Examples: USB32HDES, USB32HD2.
