V4K™ Enhanced Resolution [3840 x 2180]
Wolf Cinema’s V4K™ Technology
Originally developed by Japan's NHK Engineering and the Victor Company of Japan [JVC] and also called “e-shift” in other
devices, this unique technology implementation by Wolf Cinema delivers an HD image with 4 time s the pixel density of
standard 1920 x 1080 sources.
The original 1080p signal is first processed with an advanced imaging algorithm to improve edge transitions, eliminate aliasing
and stair-stepping, and increase contrast within each video frame. Each frame is then temporally separated into two sub-frames
[at 1920 x 1080 pixels each] and projected through the D-ILA engine and the V4K™ processing panel. This panel utilizes a
property of liquid crystals called bi-refringence and can rapidly switch between straight light and refracted light by 0.5 pixel,
shifted both vertically and horizontally. New “sub pixels” are thus generated based on this process and a true 3840 x 2160
video frame is created. Amazingly this process has no moving parts and results in a smooth, film-like image with minimal
visible pixel structure.
Depending on the projector model, you may be able to turn the V4K™ processor on and off via the following remote
control commands: Press the [OK] key, then in sequence [RIGHT] / [LEFT] / [RIGHT] / [LEFT]. A small window will appear in
the upper right hand corner of the screen, indicating the V4K processor is ON. Simply depress the [RIGHT] key to turn the V4K
processor to the OFF mode. Depress the [RIGHT] key again to turn it back on. Insure that you have the V4K engine turned ON,
then select the [BACK] or [MENU] button to end this demonstration.
