      @ptrk95 said in Save performance when rotating screen e.g. on Raspberry Pi:

      and want to rotate the screen you can rotate

      Did you counter clockwise rotated you screen ?
      And therefore did ``transform: rotate(90deg);```??

      I originally rotated my screen clock wise (so the top now is on the right hand side) using /boot/config.txt and display_hdmi_rotate=3.
      This works fine.

      When I use your css example and take out the /boot/config.txt line, it does not work right.
      I figured I need rotate(270deg), but then I do not see anything.

      Besides that, the omxplayer modules need to be adjusted too (–orientation parameter), so I reverted back to my old method.

      My question: can you setup your screen so that it rotates this way that you see everything upside down (to simulate a clockwise rotation in your case) ??
      And then share the css code.

        @evroom Yes, I did rotate it counter clockwise.

        I found a solution that worked for my setup, rotating the screen 270:

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

        Tell me if that worked for you. Then I`ll update the post :)

        Adjusting the omxplayer orientation is one of the drawbacks.

          Almost, but not quite.
          It does rotate clock wise, but it is centered.
          In Excel analogy: vertical alignment: center.
          I would need ‘top’.

          This is my custom.css, probably the other settings interfere:

          body {
            margin: 0;
            position: absolute;
            transform: rotate(-90deg);
            transform-origin: top left;
            width: 100vh;
            height: 100vw;
          
            object-fit: cover;
            top: 100vh;
                  visibility: visible;
           }
          
          .region.top.left {
            width: 60%;
          }
          
          .region.middle.center {
            width: 60%;
          }
          
          .region.bottom.left {
            width: 60%;
          }
          
          .MMM-HTMLBox {
            font-size: 18px;
            line-height: 22px;
          }
          .MMM-RTSPStream header {
          
            text-align: left;
          }
          
          .MMM-RTSPStream .innerWrapper {
            border-style: none;
            //border: 1px solid red;
          }
          

          I want the left side modules to occupy 60% and the right side modules 40%.
          Maybe I have to interpret top, middle and bottom different now ?

            Okay, found it.

            In my /boot/config.txt I had the width and height set to 900 and 1600 and this has to be now 1600 and 900.
            This is working:

            display_hdmi_rotate=0
            framebuffer_width=1600
            framebuffer_height=900
            

            Works now.

            Only need to modify the omxplayer lines to have those streams rotated too.

              Didnt work that easy for me.

              1. You have to take the resolution of your display/monitor in the config.txt, not just 1600,900.
              2. I had to enable overscan, cause the picture was to big.
              3. If you’re using the MMM-Remote_Control the picture is rotated when you have a look at your MagicMirror.

              I switched back to the fake KMS driver.

                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.
