Optoma Technology TX551 用户手册

The projector provides two VGA input sockets that allow you to connect them 
to both IBM

®

 compatibles and Macintosh

®

 computers. A Mac adapter is 

needed if you are connecting legacy version Macintosh computers.
To connect the projector to a notebook or desktop computer:
1. Take the supplied VGA cable and connect one end to the D-Sub output 

socket of the computer.

2. Connect the other end of the VGA cable to the VGA1-IN/YPbPr or 

VGA2-IN/YPbPr signal input socket on the projector.

„

Many notebooks do not turn on their external video ports when 

connected to a projector. Usually a key combo like FN + F3 or CRT/
LCD key turns the external display on/off. Locate a function key 
labeled CRT/LCD or a function key with a monitor symbol on the 
notebook. Press FN and the labeled function key simultaneously. 
Refer to your notebook's documentation to find your notebook's key 
combination.

If you want to view your presentation close-up on a monitor as well as on the 
screen, you can connect the VGA OUT signal output socket on the projector 
to an external monitor with a VGA cable following the instructions below:
To connect the projector to a monitor:
1. Connect the projector to a computer as described in 

2. Take a suitable VGA cable (only one supplied) and connect one end of 

the cable to the D-Sub input socket of the video monitor.

Or if your monitor is equipped with a DVI input socket, take a VGA to DVI-A cable and connect 
the DVI end of the cable to the DVI input socket of the video monitor.

3. Connect the other end of the cable to the VGA OUT socket on the 

projector.

„

The VGA OUT output only works when VGA1-IN/YPbPr or VGA2-IN/

YPbPr is made to the projector.
