Hdmi Link Assurance Series Home Theater

The problem seems to be related with the one described in the following link: The problem does not happen when using 3840x2160 at 30Hz.

I can live without HDMI, but I am wondering if this a driver or a display hardware problem.

I have gone from 10 Bit colour and 144Hz, down to 8 Bit colour and 120Hz.

I bought a gold-rated 750 Watt PSU and that seemed to fix my problems until I cranked up modern titles.

Samsung screens are possibly the cause of this Click to expand.

Also note that I dont get a no signal message when the displaymonitor goes off, but the HDMI and port number does appears every time the displaymonitor goes on.

I dont really know what else to try other than switch to DisplayPort and forget about HDMI.

Are you using a HDMI 2.0 certified cable And lastly, you could always try using CRU and editing the HDMI and HDMI 2.0 extension blocks and increase the TMDS clock and the TMDS character rate respectively (whether or not this will work or if there will be any danger in doing this I cannot say unfortunately).

If your TV or video projector still does not recognize the HDR source after changing settings and upgrading cables, contact tech support for either the TV or the HDMI source device.

As the standard connection device for TVs, game consoles, video projectors, media streamers, and set-top boxes, HDMI is an important component of any entertainment set-up.

HDMI is supposed to make it easy to connect all your devices together with the use of one cable for both audio and video.

To do this, connected devices must be licensed to communicate with each other through a standard known as HDCP.

This ability to recognize and communicate media and devices is referred to as the HDMI handshake.

If the handshake doesnt work, that means the HDCP encryption embedded in the HDMI signal is not recognized by one or more of the connected devices.

This usually results in you not being able to watch your movies or play your video games.

Here are some steps that may help correct HDMI connection problems so you can get back to gaming or watching.

HDMI connections dont fit as tightly as a component or composite video connection and sometimes slip out.

If this happens often, consider getting locks for your HDMI cables or self-locking cables.

If you have several different HDMI components, try starting them up in different order combinations.

Failing that, plug your device into a different HDMI input and repeat the above steps.

Some devices are tuned to specific channel inputs and require you to tune to that input on your TV remote.

If so, reset it to match the built-in resolution of your TV or video projector, such as 720p, 1080p, or 4K, if you have 4K-capable TV or video projector.

If that works, then the receiver or intermediary device youre using is likely the problem.

Keep the HDMI source connected to your TV and make a separate audio connection from your device to the the TV until you can determine the problem with the receiver.

Also look for user comments or complaints regarding HDMI handshake issues, and follow discussions and links to the proposed solution.

The implementation of HDR in many 4K Ultra HD TVs has been know to cause HDMI connection problems.

Make sure your audio receiver or other intermediary device is HDR-compatible.

If you havent already, swap out your HDMI cable for a Hi-Speed HDMI cable with a speeds of at least 10.2 Gbps, but preferably 18 Gbps.

If you have an HDR-enabled device, such as a UHD Blu-ray player or streaming device, connected to an HDR-compatible TV, its possible that the TV is not recognizing the HDR-encoded content.

When an HDR TV or video projector detects an HDR signal, a confirmation should appear on the screen.

If it does not, the problem may be a matter of compatibility rather than connectivity.
