The Wobulator
Images without Wobulation (top) are dramatically improved by 
two-position Wobulation, which doubles the resolution.
The technology story: 
HP Visual Fidelity and 
Wobulation
HDTV and HP Visual Fidelity
Thanks to HP’s Visual Fidelity technologies—the 
power behind the picture—our HDTVs deliver 
unrivaled image quality and color brilliance. 
In LCD and plasma models, HP Visual Fidelity 
technologies provide an advanced video pipeline 
that combines photorealistic sharpness enhance-
ment, scene-by-scene contrast adaptation keyed 
to the room’s ambient lighting, and a 3D color-
enrichment system. 
HP Visual Fidelity includes technologies such as 
Wobulation, which doubles the pixel resolution to 
provide brilliant, crisp, true-to-life images. (See 
illustration, above.) The lamp is brighter, offering 
more accurate, vivid colors and an ultra-wide 
viewing angle. And DLP
™
technology fine-tunes
each individual pixel for a cleaner, sharper image.
All HP HDTV models feature high contrast ratios for 
brighter lights and deeper darks. That means truer 
blacks—enhancing image sharpness and power, 
whether the scene is action-packed or brightly lit 
or darkly shadowed. It means subtler color detail. 
And it means increased tolerance of ambient light.
The bottom line? A viewing experience like no 
other, rich with stunning detail and true-to-life colors.
Microdisplay TV and Wobulation
Wobulation is a funny name for a great technology. 
And it’s another great example of HP ingenuity at 
work—leveraging our industry-leading inkjet tech-
nology into new and dazzling consumer products.
Here’s how: both printers and digital projectors 
create a color picture from a matrix of primary 
color points. Historically, print resolution was 
increased by placing more and overlapping ink 
droplets within the same size grid; initially, 
300 x 300 dot-per-inch (dpi) resolution became 
600 x 300 dpi. That yielded significantly better 
image quality from the same size dots of ink. 
HP engineers simulated applying the same principle 
to “droplets” of light, with exciting results. Same 
size spots, yet dramatically improved image quality. 
In fact, the resulting light-imaging technology—
Wobulation—doubles the addressed resolution of 
non-Wobulated, digitally projected images, without 
diminishing their renowned crispness. This technology 
virtually eliminates the screen-door effect commonly 
seen in other displays. And it’s accomplished with-
out expensive modifications, like changing the light 
modulator or increasing pixels. 
Better resolution, eye-popping picture quality, 
virtually no increase in cost. So, HP customers who 
choose our MDTVs get the best possible HDTV 
viewing experience at a price they can afford.
