- I acquired a Truevision Bravado card and the following are some problems
- that I encounter:
-
- 1. I have problems running applications (eg windows 3.1, animator pro,
- etc) in 800x600 resolution mode. The manual says that the horiz.
- scan rate = 38KHz and the vert. scan rate = 60 Hz for the card.
- However, my monitor manual says it only goes up to 35 Khz and 56 Hz
- respectively. Is the difference in frequency that is causing the
- problems? Are there other ways of overcoming it other than to change
- the monitor?
-
- 2. Images grabbed from the video window is stored either as a 24-bit or
- 16-bit true-color targa file. When I displayed it in 640x480 256
- colors, the images looks terrible. The vendor claims that it is due
- to the low resolution of my display. Is it true? Are there any
- converter programs that can convert 32,000 colors images to 256 color
- images?
-
- Any help to the above problems would be greatly appreciated.
