Using 422 Evans

Setting up the Television

You can turn on the TV by pressing the large red power button on the remote. There are three ways of displaying content from your computer to the TV: using a VGA cable, using an HDMI cable, and wireless via Chromecast. The two cables are coiled at the front of the room behind the cabinet. Choose whichever cable can connect to your laptop with or without a video dongle. Press the Input button on the remote, then use the arrows to select either VGA Cable, HDMI Cable, or Chromecast.


  • If you are using the VGA cable, connect its thin, line level audio cable to your computer to prevent the TV from buzzing.
  • If you are using a Mac and the TV complains about the resolution, you may need to tell your Mac to adjust the display size it is sending to the TV. One strategy of doing this is through System Preferences > Display and unchecking Mirror Display. If this does not address the issue, click Gather Windows, then select the SHARP LCD window and adjust the resolution. Its best guess might be sufficient, otherwise select 1920x1080 if available.

Wireless Projecting

Google Chromecast icon

You may find it convenient to connect your laptop, tablet, or phone wirelessly to the TV. This is accomplished through the use of Google Chromecast; not all laptops, tablets, and phones support this feature equally. This method is mostly useful for displaying Google content such as PDFs, a presentation on Google Docs, or YouTube, but you can also display any content from within a Google Chrome browser tab. Desktop applications like PowerPoint and Skype are not supported this way.

You must connect to the room’s wireless access point, named 422, not 422 Chromecast. You will not be able to connect to the Chromecast if you are connected to AirBears, AirBears2, CalVisitor, or educause. This is because the Chromecast does not support campus authentication methods. The password for the access point is posted by the wall near the front of the room (please keep the password private to prevent mischievous students from hijacking presentations). 

Using the Chromecast from a laptop

  1. Install Google Chrome if you do not already have it, as well as the Google Chromecast extension. Quit Google Chrome if it is running.
  2. Open Google Chrome.
  3. Google has some instructions, but the basics are to click the Chromecast extension icon at the top right of Google Chrome and a small box will appear. If you want to cast your entire screen rather than just the current tab, click the arrow at the top right of the box and choose "Cast entire screen". Look for the Chromecast labeled "422 Chromecast". You may need to wait a moment for it to appear. Once it appears and you have clicked on it, your computer will be connected to the display wirelessly.
    • YouTube has dedicated Chromecast buttons at the bottom-right of each video. Initiating the casting from that button will cause higher quality video and audio to be sent to the display while omitting all of the side content, YouTube comments, channel listings, etc.
    • Google Docs is also Chromecast-aware; click Present at the top right > Present on another device > 422 Chromecast.

Using the Chromecast from a mobile device

  1. Install the Google Chromecast app from the Google Play (Android) or iTunes (iOS) store.
  2. Open the app you wish to stream to the Chromecast, for example YouTube.
  3. Click the Chromecast button within the app and connect to 422 Chromecast.
