Preview on vertical monitor

Hi,
I personally never had this, so cannot help directly. But I googled for "rotate hdmi 90 degree" and got https://www.amazon.com/Rotating-Support-Vertical-Portrait-Display/dp/B09KN8Q4RT which might be put in between TinyPilot and your server, or you google for "raspberry rotate screen 90 degree" and get something like https://pimylifeup.com/raspberry-pi-rotate-screen/ So I personally see a chance to rotate the HDMI output of the TinyPilot but it is definitely not out of the box, but I see a chance for it.
sorry for not giving a real solution, but hopefully, I could give an idea.

thanks
Juergen

Hi @yesyes, thanks for your question!

Unfortunately, there isn't a setting for switching between landscape and portrait modes. However, there is a workaround using CSS styles that you can use if you're only using a portrait display (and you're comfortable with editing some code).

I've adapted these instructions from a user on the TinyPilot GitHub repository.

First, ssh into your TinyPilot.

Copy index.html and create a backup - just in case.

cp /opt/tinypilot/app/templates/index.html /opt/tinypilot/app/templates/index.html.bak

Now run the following command to add the CSS style to the element:

OLD_HTML='<remote-screen
          id="remote-screen"
          milliseconds-between-mouse-events="600"
        ></remote-screen>'

NEW_HTML='<remote-screen
          id="remote-screen"
          milliseconds-between-mouse-events="600"
          style="height: 65vh;margin-top: 10vh;margin-bottom: 20vh;transform: rotate(0.25turn);"
        ></remote-screen>'

# Use awk to perform the substitution
awk -v RS="" -v ORS="\n" -v old="$OLD_HTML" -v new="$NEW_HTML" \
  '{gsub(old, new)} 1' /opt/tinypilot/app/templates/index.html > temp.html && \
  sudo mv -force temp.html /opt/tinypilot/app/templates/index.html

You may need to alter the styles to match your orientation (particularly rotate in NEW_HTML if the portrait orientation needs flipping).

If you need to revert back to portrait mode, ssh into your TinyPilot and then run the following command:

sudo cp /opt/tinypilot/app/templates/index.html.bak /opt/tinypilot/app/templates/index.html

I should let you know that TinyPilot software updates will overwrite these changes - meaning you'll have to run these commands again if you update.

Hope that helps! Please let me know if you have any questions.
