Description
Hello.
We have been having trouble connecting our office laptops to our conference room screen though HDMI. Even though the computer is plugged in, the screen will say no input available when prompted to choose the HDMI.
For reference, as our office computers we use a Dell laptop that is fairly old. We might just need a new office computer, but it might also be an HDMI problem. If someone could come look at it we would appreciate it.
