      Hello,

      Iam struggeling on my PI3 to rotate by 90deg to right. Monitor has 1920x1080.
      But I see only black screen at any other position than -90deg!!
      As I need to change to 90deg or -270deg I got only black screen (also 180deg even) …

      So I changed config.txt to:

      display_hdmi_rotate=0
      framebuffer_width=1920
      framebuffer_height=1080
      

      & custom.css to:

      body {
              margin: 0;
              position: absolute;
              transform: rotate(90deg);
              transform-origin: top left; 
              width: 100vh;
              height: 100vw;
              object-fit: cover;
              top: 100vh;
              visibility: visible;
      }
      

      What is missing?

      Worse case I change physical mounting way, but not preferred :face_with_stuck-out_tongue_winking_eye:

        transform: rotate(90deg);
        transform-origin: top right;
        

        works at least see have screen, but only half screen is used, so no option…

          Warning! Extreme newbie here. This is only my second day playing with Magic Mirror css.

          I changed my css file and boot/config.txt following @evroom’s instructions above and although I was able to rotate the screen with these instructions, like @Joern, the Magic Mirror modules only fill the bottom half of the screen.

          My CSS file is as follows (sorry, I don’t know how to put this in a separate box):

          body {
          margin: 0px; If I omit “px”, Magic Mirror does not display correctly.
          position: absolute;
          transform: rotate(90deg);
          transform-origin: top right;
          width: 100vh;
          height: 100vh; If I change this to “100vw”, Magic Mirror does not display correctly.
          object-fit: cover;
          top: 100vh;
          visibility: visible;
          background: #000;
          color: #aaa;
          font-family: “Roboto Condensed”, san-serif;
          font-weight: 400;
          font-size: 2em;
          line-height: 1.5em;
          -webkit-font-smoothing: antialiased;
          }
          .MMM-HTMLBox {
          font-size: 18px;
          line-height: 22px;
          }
          .MMM-RTSPStream header {
          text-align: left;
          }
          .MMM-RTSPStream .innerWrapper {
          border-style: none;
          }

          …a few more entries after these ones.

          My boot/config.txt contains the following entry:

          display_hdmi_rotate=0
          framebuffer_width=1600
          framebuffer_height=900

          Any entries shown here that were not included in @evroom’s instructions, are from the original installation of Magic Mirror.

          I’m running Magic Mirror latest software on a Pi4 with an Acer 24" monitor.

          Any ideas as to what I should change in order for the modules to fill the entire screen?

          Any help will be greatly appreciated.

            after you paste the text, select it, and then push the button above the editor that looks like </>

                Never mind guys I was able to get it to work by following the instructions here
                After all it wasn’t the css file that I needed to change, but the Pi autostart file in the /etc/xdg/lxsession/LXDE-pi/ folder.

                  Thank you @ptrk95, that just came in handy while playing around with fullpageos and the magic mirror in my docker setup!

                    Hi there! thanks for the easy fix! Is there a way to reposition the modules on the mirror? when I rotate the screen 90 degrees the bottom module (the newsfeed) its completely cut out.
