HDMI source lost after toggling inputs

I have several generic 42" TV with HDMI inputs used to display company information. Each TV has an Intel Compute USB stick to run Windows and content.
One of the TV's also has a Bell express-vu satellite receiver connected. We find that if we switch input from Windows to Satellite, then back again we have lost signal on Windows, just static is displayed. It wont recover unless we reboot the stick. It the satellite is unhooked we can switch input sources with no issue. Tried reversing the ports, no help.

Does anyone know what is causing this? Is it a fault of the TV, the Stick, or the Satellite?  Or is this expected behavior?

Sounds like the TV itself may not handle the resolution change well. Either that or the computer thinks the monitor is disconnected, but it should recover from that. One thing you could do to troubleshoot is hook up another monitor to the PC, then have the TV as a secondary monitor and switch to satellite to see how it responds when you switch and then switch back.

Also, make sure all your video drivers and the USB stick drivers are fully updated.
