(1.)Text
Text is by far more readable than with other display technologies. BUT...
As you can see in the image above there are blue and red fringe lines on either side of every letter or font.
The problem is that the red, green, and blue lasers are not perfectly aligned with respect to each other which means that the image for red, green, and blue are all scaled independently of each other. This in turn causes a color “aliasing” when looking at text close up.
I found out a way to negate this effect completely tonight.
The laser setup is RGB like most monitors BUT there are some monitors that are setup for BGR.
You will need to do a alteration of the subpixel layout from RGB to BGR on the OS you are using.
I know several of you have already bought a showwx+ so hook it up right now and examine this image closely to understand what I mean...
Notice how the example subpixel BGR looks the best on the showwx+?
Thats because its reversing the RGB alignment and 'correcting' the font into solid black by reversing the RGB order.
(Even messing with the lasers individual laser alignment never got rid of the color fringing in font before now.)
You can change the sub pixel layout in Windows by using ClearType. Firefox allows you to force webpages to use the fonts you specify by unchecking "Allow pages to choose their own fonts instead of my selection above" in the advanced fonts settings. I use this to force Windows ClearType fonts in Firefox.
Run the ClearType optimizer thingy in windows 8. It’s supports BGR.

Laser speckle
The laser radiation speckle can be...distracting.
With its grainy appearance and shifting pattern when you move like 1cm, it can be a problem.
The speckle issue is caused by the very narrow bandwidth of the lasers used. They have a lot of coherence with no mode hopping, which is great for holography but awful for display tech.
(Beam scanning lasers requires “single mode” lasers that don’t “hop” because the hopping turns into intensity/color variations in the beam scanning process thus making a noisy image.)
(I created a special screen for back projected displays that eliminates speckle by %100 by decreasing the longitudinal coherence lengths of the emitted light, the speckle generating mutual interference of wavefronts is also reduced completely.)
If there is enough interest I can put the screens on Ebay and sell them that way for those of you that may want one.
Just let me know.

It's 16 Bit color depth
The number of bits used to represent RGB values has nothing to do with colour space (except that using only 8 bits in colour spaces wider than Adobe RGB is a bit of a nonsense, as the steps between adjacent values are too wide).
16 bit vs 24 bit is never about extending the gamut, but always about increasing the number of possible pixel values within any given gamut. It depends very much on the image whether you’d see any benefit.
The only thing a higher bit path to the display would bring to the party is less banding and a lower dE between two similar colors previewed. Bit depth and gamut are separate entities (although the wider the gamut, the more reasons why you’d want a wider path).

'Scan' lines.
The showwx does 480 progressive, but, it is shifting the scan lines VERY quickly to fill in the gaps. when displaying video, the scan lines moving around can be visible and distracting. This might work great at a higher refresh rate, but at it's native 59.9hz it doesn't cut it.
Use PowerStrip to up the Hz of the ShowWX+ to 72hz to reduce this visual artifact to an unnoticeable level.
