      Great hack!! I’m going to add this to my CSS 101 guide if that’s OK. I think this is incredibly useful.

          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.

                    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.
