Digital Video/Audio Out

  • Compatible with most modern monitors and TVs.
  • All Amiga screen modes (OCS/ECS/AGA/RTG) are output from this interface.

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. In particular, non-RTG (OCS/ECS/AGA) screen modes are output to Digital Video as follows:
    • PAL mode:
      • Low Res / High Res ⇒ 720×576@50Hz (standard PAL)
      • Super-High Res ⇒ 1440×576@50Hz
    • NTSC mode:
      • Low Res / High Res ⇒ 720×480@59.94Hz (standard NTSC)
      • Super-High Res ⇒ 1440×480@59.94Hz
    • Interlaced modes are output as interlaced scan. Non-interlaced modes are output as progressive scan.
  • 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)


  • All Amiga audio is output from this interface, as digital audio.
  • If your monitor or TV has built-in speakers, you can play the audio from there.
  • Some monitors and TVs have audio output or headphone jacks, so you can pass the audio through to a different device.
  • Alternatively, from the Vampire's Digital Video/Audio signal, you can extract the audio to various output formats (S/PDIF, analog RCA, headphone, etc.) using an “audio extractor/splitter”. (Some purchase options: 1, 2, 3)


  • You can connect a DVI monitor to this interface, using an adapter that converts Digital Video to DVI.
  • Please note that most DVI monitors cannot handle the Digital Audio signal that is sent together with the Digital Video signal. To be able to use such monitors, you would need an “audio extractor/splitter” that moves the Digital Audio signal to a different output. (Example purchase options are mentioned above.)
