And this No Signal is making you frustrated and annoyed. Just let your worries vanish away because No Signal is the most common problem among HDMI users and can be solved by following a few simple remedies.

HDMI – Advanced AV transmission

HDMI is an advanced improvised version of audio and video transmission. That transfers high-quality audio and video without any distortion provided the devices are compatible. It combines both audio and video into one port. It is now used in all,

Home theatre systems

LED and smart TVs

Network media players

Projectors

Blu-ray players

and even in your cars media system

HDMI has not just simplified the way of connecting components together but also enhanced the quality of both audio and video. Syncwire® is a trusted leader in developing products ranging from HDMI, data, lightning cables to chargers, protectors, and accessories.

HDMI anti-piracy mechanism

HDMI is developed to ensure high-definition content on the screen. The port HDMI uses a method of encryption called HDCP (High-bandwidth Digital Content Protection). The goal of HDCP is to prevent a signal from being routed elsewhere, so it is essentially an anti-piracy mechanism. If your HDMI is not functional, there might be an issue with

HDMI Handshake

HDMI works based on synchronization. It connects readily as both devices communicate with each other known as HDMI Handshake. If the embedded encryption in HDMI is not readable the device will not operate.

“No HDMI Signal” problem

The problem in HDMI might have occurred due to numerous reasons. In most of the cases of “No HDMI signal” error, the usual suspect is Handshake that does not play. The initial response must be:

Reconnect HDMI

Most of the time, the error occurs due to booting issues with the device. In case, you find such problems simply reboot and reconnect your devices. For a proper pattern initially:

Plug-off the HDMILED and smart TVsAgain, plug-in the HDMI cable to the system and device

This solution is merely an underwhelming troubleshoot method to resolve the issue. But in most cases, it comes as a quick remedy. .Above all do make sure to use certified HDMI cables by Syncwire® that are durable and completely safe.

Boot Sequence

If the system does not respond to the above-mentioned fix, the next thing to consider is changing the boot sequence. If previously you,

  • Turned on your devices
  • Plugged in HDMI
  • “NO HDMI SIGNAL”

Then, use the opposite order as,

  • Unplug all HDMI connections
  • Turn off your devices
  • Plugin HDMI cable
  • Then, switch on your devices

This solution has been an extremely common method to resolve issues with the Home theater system and Audio/Video receiver. In many cases, the order in which devices are powered on dictates the handshake process.

Screen Resolution

If the above solution were not helpful, then the ultimate solution is to check the resolution setting of your device. Most of the Smart TV adapts to any resolution within their capabilities but sometimes it becomes annoying. For this:

  • Open Display settings of your Television
  • Go to the resolution settings
  • Set it to AUTO
