However, there is another purpose for the implementation of the HDMI: copy-protection (known as HDCP and for 4K HDCP 2.2).
This copy protection standard requires that HDMI connected components be able to recognize and communicate with each other. If the 'handshake' doesn't work, the HDCP encryption that is embedded in the HDMI signal is not recognized properly by one, or more, of the connected components.
Ordinarily, there should not be a problem converting HDMI to DVI, but there can be.
One purpose of HDMI is to make it an easier to connect all your components together by using one cable for both audio and video.On the one hand, both of these options are intended to make it more convenient to connect HDMI sources and displays without an unsightly HDMI cable (especially if your TV or video projector is across the room).However, just as with traditional wired HDMI connectivity, there can be "quirks" such as distance, line-of-site issues, and interference (depending on whether you are using WHDI or Wi HD.Make sure that you go into your PC/Laptop settings and designate HDMI as the default output connection.If you can't get an image from your laptop to show up on your TV screen, try the following: Another form of HDMI connectivity that is available is "Wireless HDMI".In this case, you need to use an HDMI-to-DVI conversion cable (HDMI on one end – DVI on the other) or use an HDMI cable with an added HDMI-to-DVI adapter or a DVI cable with a DVI-to-HDMI adapter.Check out examples of DVI/HDMI adapters and cables on One other thing to point out is that where HDMI can pass both video and audio signals, DVI connections can only pass video signals.If you run into this situation a call to tech support for your TV or source component is a good idea before proceeding further.With more consumers using their PC or Laptop as a home theater source component, problems can arise when trying to connect an HDMI-equipped PC/Laptop to an HDMI-equipped TV.If you find that following those setup that issue cannot be resolved, contact Tech Support for your specific "wireless HDMI" connection product.If that still does not solve the problem, the "stability" of a traditionally wired HDMI connection setup might work best for you.
