- Macintosh AV Systems: Using with Television Monitor (11/93)
-
- Article Created: 1 November 1993

- TOPIC -----------------------------------------------------------
-
- When I connect my Quadra 660AV to a television monitor (I've tried several
- different monitors) through S-video or composite, the image is pretty
- clear. But if I select a solid desktop pattern, the color is off. For
- example, a red desktop starts out blue at the top of the screen, but fades
- to red and to purple. This happens at all bit depths.
-
- DISCUSSION ------------------------------------------------------
-
- Some discoloration can occur because televisions have marginal purity
- specifications, compared to computers. You can see some improvement by
- correctly setting the gamma setting. Here's how:
-
- 1) Open the Monitors control panel.
-
- 2) While holding down the keyboard's Option key, click the control panel's
- Options button.
-
- 3) Gamma settings will appear. Select the one for television, and the
- color should improve.
-
- Gamma correction is used to match the computer color tables to the monitor
- or television set it is connected to. This is necessary because all
- monitors and television sets do not reproduce color identically.
-
- Remember that the gamma setting for televisions is a "best guess gamma"
- because the gamma varies significantly from one television to another.
