* 1084(S) Reference
Information needed! Who made it? Common problems? Pinouts for other
connectors? Tips?
The 1084 and 1084S are 15.75 kHz monitors. They do not handle AGA "double"
screenmodes, nor will they display the deinterlaced output from the A2320
Amber board, the Microway flicker Fixer, or the motherboard deinterlaced
output on an A3000. However, they will show all normal 15.75 kHz displays,
and many (all?) of the 1084 versions have a separate input for composite
video.
Only the six-pin DIN connectors are used for analog RGB. Some 1084 monitors
also have digital RGB (CGA) inputs.
Pinouts:
Pin 1: Green
Pin 2: Horizontal Sync
Pin 3: Ground
Pin 4: Red
Pin 5: Blue
Pin 6: Vertical Sync

* 1950 Reference
Information needed! Connector pinouts, common problems, tips? Startup
resistor location and recommended replacement value?
The 1950 monitor was actually produced by a company called AOC. Parts may
still be available direct (although there have been conflicting reports).

* Idek Iiyama Vision Master 17 Reference
This is a fairly popular monitor for use with the Amiga, since it is a high
quality, relatively inexpensive 17-inch monitor that can sync down to about
23.5 kHz, and therefore works with most (all?) AGA "double" screenmodes. All
presets and controls are digital, set through three front-panel buttons and
an LCD display. The image can easily be expanded to fill the screen in all
modes. (See Boards for information on the A2320 "Amber" board that may be
used with this monitor.)
Specifications:
Sync Frequency: 23.5 kHz to 86.0 kHz Horizontal
50 Hz to 120 Hz Vertical
Resolution: Maximum 1280 x 1024 at 80 Hz
Input Connectors: Five BNC connectors and one DB15 (not high density)
(A cable is included to connect a HDD15 VGA-type
connector to the DB15 connector on the monitor.)
Pinouts:
DB15:
Pin 1: Red
Pin 2: Red Ground
Pin 3: Green
Pin 4: Green Ground
Pin 5: Blue
Pin 6: Blue Ground
Pin 7: Ground
Pin 8: NC
Pin 9: NC

Pin 14: Horizontal or HV Sync
Pin 15: Vertical Sync

* Mitsubishi DiamondScan AUM-1381A Reference
The DiamondScan is one of the few VGA-type multisync monitors that has a
composite video input, and that made it relatively common for use on the
Amiga (although I believe that Mitsubishi no longer makes this model). The
official scan rates cover the range from 15.6 kHz to 36 kHz, so the
DiamondScan should work with all normal Amiga video modes. User controls
are standard knobs and buttons, and there are no digital memory features,
so using it with the Amiga means that you have to juggle the monitor's
picture location settings along with the Amiga overscan and screen position
settings. The DiamondScan works fine with the Amber board (see Boards).
One feature of the DiamondScan is particularly applicable to the video
production uses of the Amiga: the "Composite/RGB Select" (pin 22) on the
DB25 input. Connect this pin through a switch to ground, and then a flip of
the switch will select composite video or analog RGB display without
reaching for the switches on the back of the monitor.
Specifications:
Sync Frequency: 15.6 kHz to 36 kHz Horizontal
45 Hz to 90 Hz Vertical
Resolution: Maximum 800 x 560 (Rated...normally considered
to be an 800x600 monitor.)
Input Connectors: BNC (Composite Video)
