Appendix 9 – Supported video modes
The following video modes are supported and can be automatically congured
by the AdderView CATx units. If a recognised video mode cannot be found, the
AdderView CATx will gradually change some of the key parameters to discover
whether a video lock can be achieved. Support for VESA GTF (Generalized
Timing Formula) is available and can be enabled via the Advanced Unit
Conguration screen.
The half width video modes capture every other pixel. These are not generally
recommended for normal use but may be used for emergency access to high
resolution, high frequency system screens. Half width screens can be expanded
to normal width using the scaling features of the viewer.
