3.9 Graphic Enhancement Adjustment

The optional Graphic Enhancer RGBHV VIC has a very small adjustable pot (see
Figure 3-14) that was designed primarily to improve the visibility of computer
black text on white background (such as spreadsheets). This pot is factory-set at
mid-range to provide an appreciable enhancement of small black text on white
background. HJT recommends this pot be left at the factory mid-range setting.
If it is absolutely necessary to adjust this pot to optimize a specific type of graphic
image, be sure to check that other sources viewed from the Graphic Enhancer VIC
are not adversely affected. This enhancement adjustment only affects computer
graphics and does not appreciably affect images from VCRs, DVDs etc.
Increasing (clockwise) sharpens the appearance of black on white text but
overadjustment will adversely affect other types of graphics. This is a fixed
adjustment and a compromise setting may be needed for best overall performance.
