Transition Minimized Differential Signaling (TMDS)
A technology designed to reduce electromagnetic interference (EMI) and
improve the digital signal delivered to flat panel displays. Its encoding
algorithm converts the original 8-bit graphic data into a more fault-tolerant
10-bit signal, which is then converted back to its original 8-bit form at the
display device. The signal is also DC-balanced, allowing for the option of
transmitting the signal over fiber-optic cable. DVI connectors can
incorporate up to two TMDS links, with each “link” comprised of the
number of signals required for standard RGB output. Higher resolutions
and refresh rates than standard are possible if multiple TMDS links are
available by using multiple DVI connectors.
Trilinear Filtering
A sampling method used to produce realistic-looking 3D objects. Trilinear
filtering averages one of the bilinear filter mipmap levels along with the
standard mipmap samples.
Vector Adaptive Deinterlacing
A technique that provides smoother, less jagged edges for interlaced video
playback. Interlaced video consists of alternating odd and even numbered
scan lines, which are then mapped to an equivalent pixel-by-pixel display
on a CRT or Flat Panel Display. Without correction, jagged lines appear in
a video image either as doubled scan lines or lines that are improperly
interpolated. With vector adaptive deinterlacing, the difference in pixel
values is considered across multiple lines and alternating frames (using
Pulldown detection on the interlaced video source), and then intelligently
re-interpreted to produce smoother edges in interlaced video images.
VersaVision™
An ATI technology enabling accelerated display rotation and scaling. Any
desktop can now be rotated 90 degrees left or right, or even 180 degrees,
while maintaining the full feature set of other ATI 2D and 3D technologies,
such as SmoothVision™. VersaVision™ works with single or multiple
displays.
Vertex Shader
Three-dimensional objects displayed on a screen are rendered using
polygons, each of which is made up of intersecting triangles. A vertex is a
corner of a triangle where it connects to another triangle, and each vertex
