CRT Display Calibration
To get the best picture from your CRT-based display make sure that the red, blue and green signals
are converged properly. To assist in converging these three signals abT has included two test
patterns. In addition to convergence, make sure that the focus is optimally adjusted. ABT has
included one test pattern designed specifically for this application. On some displays, these settings
may not be available unless you get into the service menu. abT recommends that you hire an
ISF-certified technician to make these adjustments if you do not feel comfortable getting into the
service menu.

To get the best performance out of each of your sources you should individually calibrate each input
specifically to the connected source. In this section, all picture control adjustments are made using
the iscan’s picture controls. Keep in mind that if you replace a source with a new component you will
also want to recalibrate the input. To calibrate each source correctly you will need the source to output
a reference test pattern similar to what is built in to the iScan. For sources like DVD, LD and D-VHS,
this content is readily available. But for a source like HD satellite or cable, these test patterns are
played on channels like Hdnet at off hours. so if you have a dVr abT recommends that you record
these test patterns.
aVia will assist in setting up the input to which your dVd player is connected. abT recommends that
you use a digital connection, DVI, HDMI or SDI, or a high quality analog connection, component
video. Don’t use S-Video or Composite video for a higher quality source like DVD. Before calibrating the
input for your DVD player, make sure that your DVD player is set to ‘16:9’ output, not ‘4:3’. You will also
want to turn off any extraneous features like noise reduction which may add more noise than help.
Set all picture settings on the DVD player to either ‘Off’, ‘default’, or ‘0’.
Use the test patterns included on the AVIA DVD to adjust the picture controls on this input. If you
are not familiar with how to make these adjustments, watch the guided setup first, and then make
each adjustment. You can find the guided setup by clicking ‘Advanced AVIA’ from the main menu,
and then selecting ‘Basic Video Adjustments’ on the following menu page. Each picture control is
explained in depth and the narrative will tell you what to look for in a properly adjusted display.
Once you have made these adjustments, there are several patterns on the AVIA DVD that can be
used in conjunction with the built-in test patterns of the iScan to verify the settings are correct.
Access these as follows:
1. After inserting the AVIA DVD into your DVD player, press the ‘top menu’ button to
bring up the main menu.
2. From the main menu, select ‘Advanced AVIA’.
3. On the right hand side of the ‘Calibrations’ menu page select ‘Video Test Patterns’.
4. From the ‘Video Test Patterns’ menu, select ‘Gray Scale & Levels’.
5. From the ‘Black and White Levels’ menu, select the ‘Needle Pulses’ test pattern.
This is to be used with the ‘Half B/W’ internal test pattern from the iScan.
6. Once you have adjusted brightness and contrast, go back to the ‘Video Test Patterns’
menu and select ‘Color Adjustment’.
7. From the ‘Color Adjustment’ menu, select ‘Special Color Bars’.
