Usually it’s done by pressing the AV button.
Step 2: On the laptop’s display, select the correct HDMI input. Step 1: First, insert an HDMI cable into the HDMI ports of your selected devices (laptop and output device). The general process of setting up a HDMI device is quite simple, regardless of what laptop you are using.
Yes because it is a modern standard, but (if you don’t have it and instead only) have a VGA output then you can always use a VGA adapter (VGA to HDMI converter) to make sure that your transmission is smooth, the only limitation you will face is that VGA only transmits video (not audio). The solution for this is to use another port, namely the DisplayPort (DP), mini DisplayPort (mDP), DVI or VGA. The second scenario would be if the HDMI port on your device isn’t working. Though quite rare these days except in older desktops/laptops that didn’t have HDMI ports, the simple solution is to use an HDMI adapter (i.e HDMI to VGA converter).
