If your source device has the option for adjusting the refresh rate of the output signal, ensure that your source device is outputting a refresh rate supported by your display (30Hz or 60Hz).
If so, reset it to match the native resolution of your TV or video projector (such as 720por 1080p) and see if that provides a more stable result.
Check Your Source Device’s Video Resolution & Refresh Rate Output Setting: If your Blu-ray Disc player or other HDMI source device has a video resolution output setting menu, check to see if it is set to AUTO. However, if changing the power up sequence of your TV and connected components doesn’t seem to do the trick, with both the TV and source component on, just try switching to another input on the TV and then switch back to HDMI input and to see if the signal locks in correctly. Of course, make sure when everything is turned on, and that you have selected the correct input on your TV that the Blu-ray Disc player, or other source component, is connected to. If you find a sequence that works, remember it. Try a Different Power Up Sequence for Your Components: In other words, if you have a habit of turning on your TV first, then your Blu-ray Disc player, or other HDMI source component, try the reverse power up sequence and see if that works.Īlso, if you have a Blu-ray Disc player, or other component, connected through a home theater receiver and then to the TV – try different startup combinations and see if that works. Please ensure that all HDMI connections are seated firmly and in the correct orientation of their corresponding HDMI ports. Check Your HDMI Cable Connections: HDMI connections don’t fit as tight as component or composite video connections and can slip out sometimes if equipment is moved slightly. This most often results in not being able to see anything on the display or a pink hue across the entire image.īefore frustration sets in, there are some things you can do yourself to remedy the issue. If the “handshake” doesn’t work or HDCP compliance is not met, the HDCP encryption that is embedded in the HDMI signal is not being recognized properly by one, or more, of the connected components. This is referred to as establishing an “HDMI handshake”. High-bandwidth Digital Copyright Protection requires that all HDMI connected components be able to recognize and communicate with each other. However, there is another purpose, copyright-protection (known as HDCP). 
One purpose of HDMI is to simplify connecting all your components together by using one cable for both audio and video. HDMI is now the main type of connection used in home theater setups that include HDTVs, video projectors, Blu-ray Disc players, home theater receivers, network media players, and even cable/satellite boxes.
