Latest revision as of 11:46, 9 July 2019

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

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 640*480,

the HDMI display cannot display normally or even without display.

hdmi_cvt 480 320 60 6 0 0 0

Change the value of 480*320 to 640*480, 800*480 or the higher resolution (note the space),
For example: change to 800*480 resolution

hdmi_cvt 800 480 60 6 0 0 0
