Hi, people. Just now, when I put a HDMI cable and I connected the cover keyboard my screen turned upside-down when I use the extended mode of monitor projection. If I use the clone-screen mode it is able to arrange the correct position. If I turn off the projection or unplug the HDMI cable the Surface is able to to be right, too. Only in extended screen mode it turn the screen of Surface upside-down, but the other monitor stay in the correct position. I used this device several times. It is usual this use every day. But today the cover keyboard was not working, and I moved the Surface with the cable connected and unplug and plug again the cover to fix its function... then the screen frozen in the upside-dowm position. What can I do to turn it to correct position?
