preset is per input and per format.
Setting up an iScan VP30 Using the Internal Test Patterns and Avia:

Determining the Correct Output Resolution for Your Display:
determine the optimum output resolution to set your iscan Vp30 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
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 an iScan VP30 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 iScan VP30 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:
Diagonal Screen Size (inches): 53
Aspect Ratio: 16:9 (Widescreen)
CRT Type: 7” Diagonal
HDTV Compatibility: 540p/1080i
This display only displays two resolutions, both of which the iScan VP30 can output. To find out which
one looks best on your display use familiar material, like a favorite DVD, to compare to find out which
resolution is more to your liking on your display.
a small amount of displays’ documented native resolutions are incorrect. according to the information on
Fujitsu’s web site, the native resolution of the Fujitsu 50” plasma (Model P50XHA10US) is 1366x768.
