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

RE: Wiveshare 7.9" DSI - 400x1280@60Hz - Tim Curtis - 02-26-2023

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?

RE: Waveshare 7.9" DSI - 400x1280@60Hz - Patolog1964 - 02-26-2023

There is a button on the back of the display.
