Wondering if anyone has had any experience with the Virtual Research HMD's. Wondering specifically what is the end result of a display like the V6 having not one RGB triad per pixel, but 1/3 of that?

An analogy would help if y'all can think of one.

AFAIK 640x480x3 means that there are 307200 pixel units for each of the component colours (R,G,B) which gives the display total size of 921600 pixels.

With 640x480x1, it is either monochrome (one component signal) or the 3 have to share 307200 pixels and each component is actually having only 102400 pixels.

I actually asked this question of Evan at Virtual Research. His response is that the display is 1/3 the resolution of standard VGA.

I am having trouble wrapping my mind around that. It takes a 640x480 signal, but displays it at 1/3 of that?

Its because in an LCD it takes one pixel per color. If you have want color, which is Red, Blue, and Green, it requires 3 pixels to actually make one color pixel. So you actually getting 1/3 the resolution.

That helmet is still , what around $6,000 LOL

Thier V8 is now a true 640x480... I remember trying the V6 at foxwoods casino 3 years ago and they had Unreal Tourny playin.. The FOV was good enough and the Res was on the average.. Now for that price of that helmet that they told me was discontinued and still top $$$$$ IS crazy..
