5.2 Setting up an DreamScaler3 Using the Internal Test Patterns
The DreamScaler3 has 35 built-in test patterns to assist in the setup of your display and your individual sources.
DreamVision recommends that you use the Avia Guide to Home Theater DVD to assist in this setup.
Determining the Correct Output Resolution for Your Display
Determine the optimum output resolution to set your DreamScaler3 to get the best picture from your display. To do
this correctly, you must know what the native resolution or maximum resolution of your display. Native resolution
refers to the actual pixel count of a fixed pixel display. Fixed pixel display technologies include plasma, LCD, DLP
and LCoS. CRT-based technologies use scan lines so they do not have a native resolution but they do have a
maximum resolution.
Keep in mind that some displays do not accept their native resolution. The following is an example of specifications
from an LCD TV:
• Diagonal Screen Size (inches) 32
• Display Capability 480p/720p/1080i/p
• Aspect Ratio 16:9 (Widescreen)
• Resolution (Number of Pixels) 1280 x 768 (1,049,088 pixels)
The native resolution of this display is 1280x768, which a DreamScaler3 can output, but this display is only capable
of accepting 480p, 720p, or 1080i signals. For this display, the best output resolution to choose on the
DreamScaler3 is 720p, since it is the closest to the native resolution of this display.
An example of the specifications from a CRT-based rear projection display is shown below:
