The Bose VS-2 is not fully functional with HDMI. The screens repeatedly go black while you are just sitting there. Tech support tells you all the ways to 're-handshake' the HDMI sources, but it does not fix the problem. You either have to change the Bose output resolution to a lower value and if that works change it back to your default 1080p setting. If not, you have to shutdown all component and the BOSE system. Unplug the Bose for 30 sec, forcing a H/W reset. Then restart each component. Once they are all up, the start the Bose.
I have been met with 50/50 success on this. In the space of a 4 hour period I had to do this 5 times.
All Bose suggests is go to the Component Video cable. The offer no solution, and just blame HDMI. This is totally false. I have another system, not Bose where the HDMI works fine.
BTW, Bose apparently does not make use of the audio going across HDMI. You still have to hook up either optical, digital coax or analog RCA cables to get audio from your sources.
Bose has very much falsely represented this system.
