Connecting to a Display
Figure 4-5 DVI-I output connector
By connecting a display to the DVI-I output connector, you can display a variety of screens.
Using a commercially available DVI-I cable, connect the LV 7770 to an XGA (1024 × 768)
display.
The default value of the aspect ratio is 4:3, but you can use the system settings to change it to
16:9 or 16:10. (The display must have a resolution conversion feature.)
See section 7.1.2, “Rear Panel Settings” and 7.6, "Selecting the Aspect Ratio."

To turn on the power, press the power switch. The power switch LED lights, and the instrument
turns on. When you turn on the power, the LV 7770 starts with the same panel settings that
were being used when it was last turned off.
To turn off the power, hold down the power switch for one second or more. The power switch
LED and the instrument turn off.
