Hi, i have an old computer and a monitor. If i plug in before i turn my pc on, my monitor will not be rocognized. I tried to connect to my pc with anydesk and the resolution was really small (i remember that it was 800*600. But if i turn my pc on with unplugged monitor, and my desktop is visible then if i connect my monitor it is working. I tested with my tv too, and it showed picture. What can i do?
