If your laptop has an HDMI port, you can connect using HDMI. If you do not have an HDMI port, you may need to use an adapter to connect to either HDMI or VGA.
NOTE: Classroom Tech only provides 6-foot HDMI cables for classrooms.
OIT recommends when connecting using a cable to connect to HDMI in your classroom, if possible. When you have chosen how you will connect, choose the option for either HDMI or VGA on your Control panel. If you are unable to connect using a cable, use the Cynap in the classroom to connect wirelessly.
NOTE: VGA is listed as laptop in some classrooms on the AMX panel. HDMI may be listed as HDMI 1 or HDMI 2, if multiple HDMI cables are available. The top cable will be HDMI 1.
What's the difference between HDMI and VGA?
- HDMI is a newer technology. It is digital. Sound and Video travel over the same cable. The quality of the video is higher. This is the current industry standard for monitors, projectors, televisions, etc.
- VGA is an older technology. It is analog. When using VGA, if you want to play sound, you need to plug in the attached audio cable into your headphone jack in order for the sound to play.
- Note: connecting to VGA can sometimes help if you have experienced a green screen on your computer when trying to show something on a screen. This usually happens when trying to display on a Cynap. Alternatively, try connecting to the Cynap wirelessly as well.
