About WalVisions



About WalVisions

WalVisions is a creation of Walter Allen, a now retired 30+ year professional in the research & development, design, manufacture, sales and service of large screen video displays. Mr. Allen was Chief Video Engineer at Advent, where "modern" day video projection was born in the early 1970s. Since then he has held the titles of either VP Engineering or VP Technology at Kloss Video, AmPro and Elite Video. He worked extensively with Henry Kloss in making the earlier projectors come to life. He has had video projection in his home continuously since 1974, with the smallest projector being 64" diagonal. He has lived with Wall Visions (video projection onto a white wall) since 1983. You can contact him here.

If you are wondering about our logo, not only are we conveying the W stacked on the V for WalVisions, but there are also aspects denoting stability, growth, balance, and the center has a very positive connotation!  Yet overall there is a hint of vulnerability, as in life and the world, things can't be taken for granted or the whole thing could collapse.  It's also nice that the logo is easy to replicate!

If you are wondering about the largely gray/colorless themes on all the pages, this follows the theme of the test patterns in a couple of ways.  Firstly, it provides an immediate quick check of your monitors gray scale - if the backgrounds and various levels of gray appear to be tinted in any way, your monitor is likely in need of adjustment.  Secondly, as you view the pages your eyes will be neutralized and thus should not retain any "color memory", then when you subsequently check various test patterns involving color or gray scale, you will be doing so with a neutral starting point.
