Introduction
This page explains what you'll need to know to use the Hitachi CP-X8150 projector on the Siemens Skyra 3.0T MRI scanner in NHB. This projector was installed 8 Aug, 2019, and replaced the ViewSonic that had been in use for just a few weeks. The replacement was necessary due to unforeseen filter incompatibility issues. This projector supports HDMI, mini-DP (aka mini-DisplayPort), and DL-DVI (aka Dual Link-DVI) inputs from laptops. The projector is turned on and off using a remote control similar to the way the old PROPixx projector did.

Important Reminder
Please, when following the direction below, make sure that you do not press any buttons on the projector other than ON and STANDBY, as appropriate. Pressing other buttons could change the configuration of the projector, and have adverse effects on the quality of your video.
Turning Projector On
0) IMPORTANT: Make sure that AT LEAST five minutes have passed since the projector was put into standby mode. If you try to turn it on while the projector is cooling down from its last use, it may look as though it is not functioning properly.
1) From a distance of at least two feet (~60 cm), point the projector remote at the IR receiver (seen here), and press the ON button.
2) Verify that the projector turns on by looking for a blue test image on the projection screen.
Turning Projector Off
1)From a distance of at least two feet (~60 cm), point the projector remote at the IR receiver (seen above), and press the STANDBY button twice.
2) Verify that the projector does indeed turn off by looking for an absence of any messages or test patterns on the screen. Unlike the PROPixx projector, this one really needs to be turned off when not in use otherwise the bulb's life will be significantly reduced.
Selecting the Correct Input on Video Switch
1) First determine which input you will use: HDMI, mini-DP, or DL-DVI. Once you have, select the appropriate input cable, and plug it into your laptop. Note that each cable is labeled with the input name selectable on the video switch - HDMI goes to the input labeled HDMI 1, mini-DP goes to HDMI 2, and DL-DVI goes to HDMI 3.
2) Select the input you need on the face of the video switch. The names (HDMI 1-4) are touchable buttons. For example, if you are using the HDMI cable, touch "HDMI 1" on the face of the switch, etc.
3) Ensure that the resolution selected on the video switch is 720p (even though you're going to force your computer to use 1024x768 in the next step).
4) Configure your laptop to send 1024x768 at 60Hz to the secondary display.
