Sometimes, you need to connect your monitor to a larger screen. You will often do this using an HDMI cable, which may even connect to your TV. Sadly, some users have complained of the error: no HDMI signal from your device in Windows 11.
A faulty cable, bad or outdated drivers, misconfiguration, or other display detection issues may cause this problem. We help you fix it with the solutions below.
1. Preliminary Checks
Before you go into complex fixes, we recommend the following preliminary checks.
Check if Connections are Properly Done
You should check that your HDMI cable is fitted tight into the ports. A loose cable will probably not have contact and produce no signal.
Use a Different HDMI Cable
If you have a spare cable, you may try using it. It is an easy way to rule out a worn-out cable as the cause of the problem. You may also try the cable on a different device to be sure it works.
Use a Different Port
Also, take a look at your ports. If you have dust or some other dirt stuck in the ports, they may obstruct contact and lead to no signal. You should clean them or blow dry air through them to remove dirt. Alternatively, you may try connecting with a different port.
2. Manually Detect Your Connected Display
If you are connecting to an old TV or monitor, Windows 11 may show no HDMI signal from your device. In this case, you will have to detect the connection manually. Follow the steps below.
1. Open the Settings app by pressing Windows + I.
2. On the left pane, click System, then click Display on the right.
3. Expand Multiple displays and click the Detect button to Detect other displays.
3. Select your Second Display Manually

2. Expand Identify and choose Show only on 2.
