  The PBXGB-AA PowerStorm 3D30 (TGA2) is probably the nicest controller
  with formal support, IIRC. Even if the PowerStorm 3D30 is supported,
  it is probably overkill for this AlphaStation 200 series box.

  For hardware support details:

  The AlphaStation 200 box is sufficiently old and slow that I'm not at
  all certain the graphics board would be my first target for an upgrade.
  Y'all are simply not going to get performance from an ancient EV4-based
  system, no matter the graphics controller chosen.

  The 3DLabs Oxygen VX1 device drivers will not function with an EV4-class
  Alpha microprocessor, such as that found on your AlphaStation 200.

  The PowerStorm 3D10T ELSA GLoria Synergy is probably the newest card
  that has a shot of working, though I do not know if that would be
  supported in this configuration.

  Various of the older AlphaStation systems either lacked the byte-word
  instructions (systems prior to EV56) or the platform-specific PCI bus
  I/O addressing that can be required by more recent device drivers;
  adding support for newer graphics onto older systems is not something
  that is normally expected.

  Have you tried other resolutions with the TGA (ZLXp-E2) card, on the off
  chance the problem is a disagreement between the monitor and the graphics
  controller and (when present) the KVM? The switch settings for the
  ZLXp-E* series controllers are posted at Ask The Wizard topic (6965).
  This would certainly not be the first time that a controller, a KVM and
  a monitor had signal integrity problems. Try a less aggressive setting
  as a test, obviously.

  The OpenVMS FAQ has an introduction to matching up video display and
  controller settings, as well.
