HDMI display does not display after installing FBCP driver
Phenomenon
For the following products:
Following the steps of the wiki page to install the driver supporting FPCP, the above display can display normally.
However, the hdmi-connected monitor displays nothing or is prompted "input not supported", etc
Analysis
Since the default output resolution of the driver installed in the above products is 480*320,
but many traditional HDMI displays do not support HDMI input signal lower than 800*600,
the HDMI display cannot display normally or even without display.
Solution
- Open the "config. txt" file in the TF root directory,
- Find "hdmi_cvt 480 320 60 60 0 0 0" lines At the end of the file,
- Change the value of 480 320 to the corresponding value of resolution above 800*600 (note the space),
- For example: change to 1024*600 resolution
- hdmi_cvt 1024 600 600 60 600 00
- Save and safely pop up TF, insert raspberry pie and restart.
