My screen suddenly has a green or pink tint
Green or Pink Tint on videoThe green/pink screen problem is a well-known problem caused by an "HDMI handshake" failure: it's an old, misguided technology (HDCP) designed to prevent users from being able to make high definition digital copies of copyrighted content.
It's a terrible design we are all stuck with.

What you do depends on how often it happens and how much trouble it causes you.
TroubleshootingIf your TV shows a green or pink hue, it is most likely caused by a problem with what's known as the "HDMI Handshake," a negotiation between your TV and any external HDMI device that must be successful before the transmission is allowed to proceed correctly.
To confirm this is the problem: Unplug the HDMI cable from either the TV or the player.
Plug the HDMI cable back in.
If the problem clears up then you have confirmed the issue as HDMI handshake.
How to resolve the problemCheck HDMI cable connection
Make sure the HDMI connectors are securely plugged in all the way on both the player and the TV.
Force a new "handshake": Unplug and re-plug the HDMI cable whenever it happens.
Switch your TV to a different input setting and then back again.
Turn the TV off and then back on.
Use a different HDMI input port on your TV.
Change TV settings Turn off "Auto" picture settings.
Change to a different resolution.
Change HDMI compatibility settings Update TV firmware.
Replace hardware Try a different HDMI cable (upgrade to Premium Certified HDMI 2.1 cables if possible).
Move the media player to a different TV and see if the problem persists.
If the problem follows the player, call us for a replacement player (new players have a one-year warranty).
If the problem only happens on one TV, replace the TV. Learn more about HDMI Handshake and HDRC technologyThe HDMI handshake problem, a synchronization process between devices to verify HDCP (High-bandwidth Digital Content Protection), has historically caused issues like green or red hues on TV screens.
This occurs when the handshake fails, often due to loose or faulty HDMI cables, outdated firmware, or compatibility issues between devices.
Older TVs or devices not supporting HDCP may also experience these problems.
Solutions include reconnecting cables, updating firmware, or switching to alternative connection methods like component cables.
The HDMI handshake is the process where two connected HDMI devices (e.g., a TV and a Blu-ray player) communicate to establish a secure and compatible connection.
This involves: Device Identification: The devices exchange information about their capabilities, such as supported resolutions, refresh rates, and audio formats, using a protocol called EDID (Extended Display Identification Data).
HDCP Authentication: If the content is protected by HDCP (High-bandwidth Digital Content Protection), the devices verify that both are authorized to transmit and receive the protected content.
This ensures compliance with copyright protection.
Signal Synchronization: Once the devices agree on the settings, they synchronize the video and audio signals for proper playback.
If the handshake fails at any step, it can result in issues like no signal, distorted colors (e.g., green or pink tint), or error messages.
The HDMI handshake issue only happens sometimes because it depends on specific conditions during the connection process.
Factors include: Timing of the Handshake: If the devices fail to sync properly during the initial handshake, the issue may occur.
This can vary with each connection attempt.
Cable Quality or Connection: A slightly loose or damaged HDMI cable may intermittently disrupt the signal, causing occasional failures.
Device State: The problem may arise depending on the power state or startup sequence of the connected devices (e.g., turning on the TV before the source device or vice versa).
Signal Interference: External factors like electromagnetic interference can sometimes disrupt the handshake process.
Firmware or Software Bugs: Inconsistent behavior may result from outdated or buggy firmware on either the TV or the source device.
These variables make the issue sporadic rather than constant.
If two devices that have been working fine suddenly start showing a green or pink tint frequently without being disconnected, the likely causes are: Cable Degradation: Over time, HDMI cables can wear out or develop internal faults, leading to signal degradation and color issues.
Port Damage: The HDMI ports on either the TV or the source device may have developed physical damage or loose connections, causing intermittent signal issues.
Firmware Updates or Bugs: A recent firmware update on either device could introduce compatibility issues or bugs affecting the HDMI handshake.
Hardware Aging: Components in the TV or source device (e.g., graphics processor or HDMI controller) may be degrading, leading to signal processing errors.
Signal Interference: New sources of electromagnetic interference (e.g., nearby electronics or power surges) could disrupt the HDMI signal.
HDCP or Resolution Mismatch: Changes in content (e.g., switching to higher-resolution or HDCP-protected content) might stress the connection, revealing underlying issues.
To troubleshoot, try replacing the HDMI cable, switching ports, or checking for firmware updates.
If the problem persists, it may indicate hardware failure.
