The rotate 0 or 180 option was meant for screens that are mounted upside down. Landscape oriented screens should not need any display rotation.

Here's a screen shot of 1280 x 400 in the sim. The screen should report a viewport size of 1279 x 399.

   

Run the command below to show the viewport size and then refresh the Browser.

Code:

# Show viewport size
moodeutl -q "update cfg_system set value='viewport' where param='pkgid_suffix'"

# Hide viewport size
moodeutl -q "update cfg_system set value='' where param='pkgid_suffix'"

Hi Tim
after typing these command on shell ssh, no result are showed

Just enter the first command and then Menu, Refresh.

You should see a popup message showing the viewport size.

Thats a portrait orientation viewport.

Does the screen have some setting that configures it for landscape orientation?

There is a button on the back of the display.
