Underscan Resolutions
HDTVComputer or
Signage Player
When a computer is connected to an HDTV through ZeeVee encoder/modulator…
• The encoder/modulator acts like a monitor, and calls for 1280 x 720 picture
• PC produces 1280 x 720 picture• HDTV displays 1210 x 680* due to “overscan”
1280 x 720 1280 x 720
*Example only. May display more or fewer pixels, depending on the HDTV
The edges of the pictur or signage are lost
Displayed: 1210 x 680
Problem: PC Resolution choices are limited
A 1280 x 720 picture is
too big
An 1152 x 864picture is too small
Solution: ZeeVee enables more choices
A 1280 x 720 picture is
too big
An 1152 x 864picture is too small
ZvBox enables 1208 x 679!
1208 by 679 pixels

resolution that closely matches what the HDTV can display
