Beginners • Re: Pi 4B flash of the desktop, then nothing

Just curious, does it work fine using a normal computer monitor with an HDMI input?

Also, information from MS Copilot:

Copilot
This issue is often related to the HDMI signal strength and configuration settings on your Raspberry Pi 41
. Here are a few potential reasons and solutions:

Potential Reasons:
Weak HDMI Signal: The Raspberry Pi 4 outputs a relatively weak HDMI signal, which might not be strong enough for some TVs2

HDMI Handshake Issues: The TV might not be properly negotiating the HDMI handshake with the Raspberry Pi3

Configuration Settings: Incorrect or missing configuration settings in the config.txt file can cause display issues.

Solutions:
Increase HDMI Signal Strength: Edit the config.txt file on the boot partition of your SD card and add the following lines:

plaintext

Copy
hdmi_force_hotplug=1
config_hdmi_boost=4
This forces the Raspberry Pi to recognize the TV and boosts the HDMI signal strength4
.

Check HDMI Cable: Ensure you're using a good quality HDMI cable that supports high-speed data transfer.

Update Firmware: Make sure your Raspberry Pi's firmware is up to date. You can update it using the sudo apt update and sudo apt upgrade commands.

Check TV Settings: Some TVs have specific HDMI settings that might need to be adjusted, such as enabling HDMI UHD Color or similar options.
