Are you frustrated with not being able to play your favorite videos on your big screen TV via HDMI? You are not alone. Many users face this issue, and it can be really annoying, especially if you’re in the middle of a crucial movie night or when you’re trying to connect your laptop to a projector for an important presentation. In this article, we will explore the possible reasons why your video won’t play through HDMI and provide step-by-step solutions to fix this issue.
Causes of the Problem
Before we dive into the solutions, let’s understand why your video won’t play through HDMI in the first place. There can be several reasons behind this issue, ranging from simple hardware problems to more complex software issues. Here are some of the most common causes:
Incorrect HDMI Settings
One of the most common reasons why your video won’t play through HDMI is incorrect HDMI settings. If the HDMI port on your device is not selected or enabled, you won’t be able to play the video on your TV.
