- I have not had a chance to call VRG, but no HMDs currently
- have 1280X1024 resoltion especially in a 1" CRT. Correct
- me if I am wrong.

- Ditch the shadow mask and high resolution is merely a matter
- of focus and control of the electron beam, as both Kaiser and
- Tektronix demonstrated last week at the I/ITSEC visual
- simulation conference.
-
- Kaiser Electro Optics' new 1024x1280 monochrome HMD is one of
- the best I've seen. Compared with VRG's, I found Kaiser's
- lighter, easier to align, and having better overlap and
- optical design. In addition, it uses half-silvered optics
- which image at infinity, so removing the cowling allows
- see-through superposition of computer graphics on the real
- world. (Kaiser: Calsbad, CA, 619.438.9255).
-
- Tektronix was at the show demonstrating their field sequential
- color monitors in 1", 7" and 9" sizes (640x480). These use a
- monochrome montior to sequentially display red, green and
- blue. The 1" needs some work, but the color saturation of
- these monitors leaves shadow mask tubes in a gray cloud of
- dust. The clarity and sharpness are also much higher than on
- shadow mask tubes of comparable resolution. No more dots of
- RGB triads. Simply beautiful. Obviously, the 1" version will
- find effective use in HMDs.
