MHS 3.5 Inch Display

git clone https://github.com/goodtft/LCD-show.git cd LCD-show sudo ./MHS35-show

Display rotation

cd LCD-show/ sudo ./rotate.sh 90

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 640*480,

the HDMI display cannot display normally or even without display. Solution

Open the "config. txt" file in the TF root directory,
Find the line at the end of the file

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

Save and safely pop up TF, insert raspberry pie and restart.
