Peripherals for the Vampire 1200 V2

Vampire 1200 V2 Digital Video Out

  • Compatible with most modern monitors and TVs.
  • Only RTG screen modes are output from this interface. Screen modes that use the classic Amiga chipset are still output from the legacy video outputs of the Amiga.

Resolution and refresh rate

  • You can create RTG screen modes from 320×200@200Hz up to 1920×1080@28Hz.
    • As the resolution increases, the maximum possible refresh rate decreases.
    • The Vampire is able to achieve a refresh rate of 60Hz for all resolutions up to and including 1280×720. Resolutions higher than that will reduce the maximum refresh rate to below 50Hz. For example:
      • 1600×900: ≤40Hz
      • 1920×1080: ≤28Hz
  • The Vampire outputs screen modes without any upscaling. It applies pixel doubling to low-resolution modes, as appropriate, to increase them to a resolution allowed by Digital Video. This also ensures the correct aspect ratio.
  • For the best experience, you should use a monitor or TV that natively supports all the resolutions and refresh rates that you will use. Monitors or TVs that support “variable refresh rate” or “adaptive sync” usually work best.
  • If you are stuck with a monitor or TV that does not (adequately) support the resolutions and refresh rates that you will use, you can connect an “HD video converter” to adjust the signal from the Vampire as desired. For example, you can easily find converters that upscale the video signal to exactly 1920×1080@60Hz. (Some purchase options: 1, 2, 3, 4, 5, 6)

Audio

  • Audio is still output from the legacy audio outputs of the Amiga. If you want this audio to be fed into the Digital Video In of your monitor or TV, you can connect an “audio embedder/inserter”. (Some purchase options: 1, 2)

DVI

  • You can connect a DVI monitor to this interface, using an adapter that converts Digital Video to DVI.
