DblScan 4000 upgrades the Amiga's PAL/NTSC screenmodes, unsuitable for
regular VGA/SVGA/Multisync monitors, in a way that any PC's monitor is
able to show them. The resulting effect is completely compatible with
all Amiga programs.
DblScan 4000's output is full 24 bit, so not a single bit of picture
information is lost. Only the screenmodes which need upgrading are
affected by the device, all other modes are fed right through with
absolutely no changes.
DblScan 4000 is a terrific way to get even realistic interlaced pictures
and animations viewable at a large computer monitor. It shows interlaced
screens exactly in the same order as a video monitor would, while reducing
the flicker by preventing line drawings over the previous lines. With the
aid of a graphics card with pass-through for Amiga graphics, the same
monitor can be used for a very high resolution Workbench.
- Connects to Amiga 4000 video card slot
- 24 bit input/output resolution
- 28 MHz pixel generation
- All screenmodes under 18kHz are doubled
- Support for interlace (blank lines between scanlines)
- Support for NTSC variable length scanlines
- 14 MHz pixel input for doubled screenmodes
- 28 MHz pixel input and full pass-through for undoubled screenmodes
- 15pin standard VGA connector
Method of operation:
PLP DblScan 4000 feeds the Amiga's scanlines at doubled frequency, adding
an empty line after each scanline. This results as a 15kHz-able monitor
look at any monitor capable of 31kHz. Unlike a flicker fixer, which
combines the two buffered interlace fields, PLP DblScan 4000 shows
interlaced pictures correctly with full 50/60 Hz field update.
