• At least 1080p video over HDMI, and some Mac models support higher resolutions when connecting to 4K displays, 5K displays, and Ultra HD TVs; 8-channel/24-bit audio at 192kHz, Dolby Surround 5.1, and traditional stereo; HDCP-encrypted playback from iTunes and QuickTime Player (version 10).
• In some cases, a Mac laptop or desktop system won’t properly handshake with HDCP in a monitor unless mirroring is enabled or the laptop lid is closed. This should be a problem only in older Macs.

One of the ways to connect your Mac to an external display is by using a High-Definition Multimedia Interface or HDMI cable. You can connect the HDMI cable to the HDMI port on your Mac to a second monitor or TV. Whether you want to use a second screen or you want to export full audio and video display on your TV, connecting your devices is a lot easier with HDMI. Some Mac models, such as the Mac mini, also rely on HDMI to connect the computer to the display.

But with the release of macOS Catalina, a lot of Mac users using HDMI connection reported encountering various problems after the upgrade. Several users reported getting a black screen after installing the new version of macOS, even with the monitor still turned on. The display just turns black (or dark green in some cases) and eventually shuts down.

This is what I have to do every day in order to get my display back. Hopefully Apple and Samsung will one day get together and create a fix for this.

Other users, on the other hand, got a No Signal error message instead of the black screen. There are also some cases where the external display just blinks randomly when connected to a Mac running macOS Catalina.

Mac users who are using HDMI for their second monitor are less affected compared to Mac mini users who use HDMI as their main connection. However, this doesn’t deny the fact that display problems such as these can cause a lot of inconvenience and annoyance.

This guide will show you what to do if your Mac shows no HDMI signal after Catalina update.

How to Fix HDMI Signal After Catalina Update

There is no explanation yet why the macOS Catalina update caused the HDMI to stop working, and it will probably take a while for Apple to release an update that addresses this issue. If you’re using your Mac for study or work, finding a solution to this problem is a priority because you can’t do anything with a black screen.

Before you try the solutions listed below, try some of these emergency steps first to see if they work.

Fix Hdcp For Mac To Samsung Kies

1. Restart your Mac. If you’re in the middle of installation, cancel it first before restarting. Once your Mac has restarted, resume the upgrade and see if you encounter further issues.
2. Make sure that the HDMI and power cables are connected properly.
3. Use a different HDMI cable. In the case that your HDMI cable is damaged, replacing it with a new one should resolve the issue.
4. Use a different port. Try to use a different cable to connect your Mac to your display, if possible. For example, you can use a USB-C to HDMI cable for some Mac models.
5. Optimize your Mac using Outbyte MacRepair to delete possible corrupted files causing the issue.

If the above steps don’t work, try the solutions below.

1. Restart Your Display.

Restarting your TV, external monitor, or other HDMI devices should be your first step in fixing this issue. To do this:

1. Turn off your HDMI display while your Mac is turned on.
2. Disconnect the HDMI cable from your Mac, then plug it back again.
3. Turn on your HDMI display again.

If the problem is caused by a minor glitch, restarting your HDMI device should do the trick. If not, try the other fixes below.

2. Enable Your Display Driver.

If you’re using an HDMI monitor or a TV as an external display and you encounter the black screen issue, changing your Mac’s privacy settings should take care of the issue. To do this:

1. Click on the Apple logo, then choose System Preferences.
2. Click on Security & Privacy, then click Screen Recording from the left menu.
3. Tick off Enable the Display Driver in the right panel.

Changing your screen resolution and refresh rate parameters should help. Go to the Apple menu > System Preferences > Display and choose the resolution that you want.

3. Turn Off the HDMI Ultra HD Color Feature

HDMI Deep Color is responsible for creating a more realistic and smooth rendering of an image on the screen. However, there have been reports that this feature causes flickering and other screen problems when turned on. So if your external display has this feature, try turning off to see if the problem goes away.

4. Reset Your Mac’s SMC.

The System Management Controller or SMC manages a lot of aspects of your Mac, including the display. So if you’re having screen issues, such as the HDMI not working on Mac after Catalina update, resetting the SMC might help.

To reset the SMC, follow the steps below.

Fix Hdcp For Mac To Samsung Galaxy

1. Shut down your Mac.
2. Hold the left Shift + Control + Option keys together, then press and hold the Power button down.
3. Wait for 10 seconds, then let go.
4. Turn on your Mac again.

If you’re using an iMac or a Mac Mini, here are the steps to reset the SMC:

1. Shut down your device.
2. Unplug the power cable.
3. Wait for at least 15 seconds.
4. Plug the power cable back in.
5. Turn on your Mac.

Once your Mac’s SMC has been reset, check if you’re still getting screen problems on macOS Catalina.

5. Reset NVRAM.

If resetting the SMC does not fix your problem, you should try resetting the NVRAM this time. To do this:

1. Shut down your Mac.
2. Turn it back on, then immediately press and hold this key combination: Option + Command + P + R.
3. Wait for at least 20 seconds, during which your device might appear to restart.
4. Release the keys when you hear the second startup sound or when you see the Apple logo appear and disappear for the second time.

The release of macOS Catalina has also introduced a lot of bugs and issues that Apple needs to fix, including the HDMI signal problem on external displays. Rolling back to macOS Mojave is not an option because this method does not fix the issue, according to user reports. So instead of waiting for an official fix from Apple, you might want to give the methods above a try.

With the advent of affordable HD contents and higher requirements on video playback quality, more and more consumers are switching to purchase, rent, and view movies and TV shows in 720p and 1080p from the iTunes Store (learn to use iTunes Video Converter). But there is a hitch. The HD contents from iTunes Store have a companion HDCP system that sometimes leaves authorized Windows consumers receiving alert messages like:
'This movie cannot be played because it requires Windows 7 and a display that supports HDCP.'
'This movie cannot be played in HD.'
'This movie cannot be played in HD on this display.'
'To play this movie in HD, you must have a PC with a built-in display or have it connected to a display that supports HDCP.'
'To play this movie in HD, you must move the entire window onto a built-in display or a display that supports HDCP.'
'To play this movie in HD, your PC must have Windows 7 and a built-in display or a display that supports HDCP.'

Why unable to play HD video content that requires HDCP? Apple notes that “In order to purchase, rent, and view HD content from the iTunes Store on your computer, you need to have the latest version of iTunes installed, you can download the latest version here. In addition, you will need to have components that support HDCP (High-bandwidth Digital Content Protection) installed on your computer.” In this article, we’ll review what is HDCP, how does it work and how to fix HDCP compatibility issues.

What is HDCP?
HDCP stands for High-bandwidth Digital Content Protection, a form of digital copy protection developed by Intel. It was designed to protect the transfer of high quality, digital content from a video source, such as a computer, satellite television receiver, or DVD player to a receiver such as a television screen or computer monitor. Specially, the technology sought to achieve some degree of copyright protection in audio and video content, such as movies, videos, and television.

Many video and audio playing devices have the HDCP specification in them. While not all computers are HDCP compatible, some computer manufacturers have turned to HDCP to ensure additional protective measures are in place. Computers fitted with Windows Vista, for example, typically have the HDCP specification. The HDCP spec can be found in some digital video interfaces (DVIs) - a video interface standard found in display devices such as flat panel LCDs. HDCP can also be found in many monitors, game consoles, Blu-ray players that have high-definition multimedia interfaces (HDMI) as well as monitors and home theater systems that have DisplayPort interfaces.

How does HDCP work?
A simple answer is that an HDCP session will result in the exchange of keys between the source and display device. The source device will query the display to make sure that the equipment is HDCP compliant before video is shown. The source device sends a ping to the display device, much like a submarine might do. If the display device doesn’t return the ping to the source device within that period of time then the signal stops.

Let’s say you want to watch a high definition DVD on your HDTV. You connect a Blu-ray disc player to the HDTV with a HDMI cable. The instant you start playing the HDCP-encrypted disc is when the authentication process begins. In this scenario, the source device is the Blu-ray player. The HDTV is the display device. If your television is HDCP-compliant then you would see the movie. If it isn’t then you would either get blank screen or an error message.

What this essentially means is that if you use HDMI or DVI cables then you must have HDCP-compatible components in order to see HDCP-encrypted content.

How to fix HDCP compatibility issues?
The only way to fix HDCP compatibility issues is to either replace the product that doesn’t have HDCP with one that does or stop using the HDMI or DVI cable. Since HDCP is digital-only, it doesn’t affect non-digital cables like RF coaxial, RCA, component, s-video, etc.

Certified products clearly claim their HDCP compatibility (HDCP Ready), or with the HD Ready stamp.

What we would like to see developed is a type of dongle or plug that you can stick into your HDMI port that is nothing more than a HDMI/HDCP or DVI/HDCP converter. That could keep all non-HDCP televisions and devices useful with Blu-ray and other HD digital media.
