I need to display video from my laptop to a TV and the other being a projector. The TV and projector have HDMI ports. My laptop docking station has 2 display ports and I have 2 displayport-to-HDMI adapters. I have plugged these displayport-to-HDMI  adapters into my docking station and plugged an HDMI cable from the TV and projector into the adapters.

But video is only displayed on either the TV or projector. Not both at the same time. When I unplug the TV, video appears on the projector. When I unplug the projector, the video appears on the TV.

How do I get video to appear on  the TV and projector at the same time?

Which laptop and docking station are you using?  Some basic graphics chipsets only allow 2 separate displays - one digital and one analogue so you may be limited to HDMI and VGA depending on what your hardware is capable of.

If you do have this limitation you're probably better off adding a USB-based graphics card for the second HDMI output.
