800 by 600, High Color (16 bit), 60 Hertz
800 by 600, True Color (32 bit), 60 Hertz
1024 by 768, High Color (16 bit), 60 Hertz
1024 by 768, True Color (32 bit), 60 Hertz
The following are sample modes that would be selectable while you are in a
Portrait Orientation:
768 by 1024, High Color (16 bit), 60 Hertz
768 by 1024, True Color (32 bit), 60 Hertz
If you are in an 800x600x32 landscape resolution before a 90 degree rotation,
the actual resolution you will have after rotation is a portrait 600x800x32. When
you reopen the Display Settings window, the lowest resolution available for
selection will be 768x1024x8, which is different than the actual resolution. If you
select OK, then the resolution will be changed.

Wait for monitor
sync Sometimes called Wait for Vsync, this feature option
controls whether or not buffer swaps and other activities
should be synchronized to the display’s Vertical
Synchronization or Vertical Retrace Signal and blanking
period, during which the display blanks as it retraces its
way from the bottom right to the upper left corner of the
screen.
Setting options include:
By App (default) – Select By App if you want the
Wait for monitor sync setting to change on
application requests. If Vsync OFF is requested, the
back buffer is flipped without waiting for vertical
retrace. If the application requests VSync ON, then
the back buffer is flipped while in vertical retrace.
ON – Select ON to always force a wait for monitor
sync. This option will reduce “tearing” artifacts.
Synchronizing with the vertical retrace constrains the
frame rate so that it does not exceed the refresh
rate.
OFF – Select OFF to allow buffer swaps to be
processed without waiting for vertical
synchronization. When a buffer flip occurs at a
different time than during the vertical blanking period,
visual artifacts, often described as “tearing” or
“shearing” may be apparent. Note that while visual
artifacts will probably occur with this setting, the
frame rate may increase.
Anti-aliasing Anti-aliasing is a technique to reduce jagged edges
(“jaggies”) of polygons and lines. Pixels on either side of
edges are sampled and then rendered as a blend of the
adjoining colors to smooth the appearance of the edge.
When anti-aliasing is enabled, images are less likely to
display “staircase” edges and broken lines. Sampling
results can be downscaled to the original size, producing
sub-samples of high quality.
Setting options include:
By App (default) – Select By App to allow the
User Guide for Chrome 400 Series Graphics
SG192-C.1 10/17/2008
Page 113
application to specify which level of super-sampling
should be applied. Otherwise, the driver selects an
optimized value. This is the default.
OFF – Select OFF to disable anti-aliasing. Image
quality usually suffers, but performance may
increase because less pixel processing occurs.
2X, 4X, 8X – Select a level to enable optimized
super-sampled anti-aliasing. This will provide
optimized anti-aliasing and still have only a minimal
impact on performance speed.
Anisotropic
filtering Anisotropic (which means non-uniform shape) filtering is
a filtering technique more advanced than trilinear and is
a technique which is useful for quadrilateral shaped and
angled areas of a texture image. A shaper image is
accomplished by interpolating and filtering multiple
samples from one or more MIP maps to better
approximate very distorted textures. Anisotropic can be
used in conjunction with bilinear or trilinear filtering as
well as MIP map filtering. While trilinear filtering is
capable of producing fine visuals, it only samples from a
square area, which is not the ideal sampling area for all
cases. Anisotropic filtering averages sixteen texture
samples, or taps, in a non-square, rectangular or
parallelogram shaped texture sampling pattern whose
length varies in proportion to the orientation of the
stretch effect. This sampling rate is four times the
sampling level of bilinear filtering and twice the sampling
level of trilinear filtering.
Textures applied to a sloped surface will not look fuzzy,
which is especially useful when rendering shapes with a
high degree of surface tilting in the X-Y-Z planes. Full
use of the anisotropic filtering capabilities may impact
performance.
Setting options include:
By App (default) – Select By App if you want S3
Graphics software to use the anisotropic filtering
level requested by the application. Not all
applications request anisotropic filtering, and S3
Graphics software does not perform anisotropic
filtering unless requested. This is the default.
OFF – Select OFF to force anisotropic filtering to be
always off.
2X – Select 2X to enable anisotropic filtering at its
lowest level. With this setting, 16 texture samples
(taps) selected from a non-square pattern will be
averaged to generate one texture element (texel)
User Guide for Chrome 400 Series Graphics
SG192-C.1 10/17/2008
Page 114
that is then applied to a single pixel.
3X,4X,…– Select intermediate sampling levels to
match your preferred balance between quality and
performance. The higher the sampling level, the
greater the degree of filtering. Visual quality will
improve at the expense of performance.
16X – Select 16X to force use of classic anisotropic
sampling using 128 taps in a non-square sampling
pattern. This level of filtering will produce very high
quality visual output, usually with a decrease in
rendering speed.
Features:
Advanced Warning: Configuration of the following fetaures should
be done only by experienced users, as unexpected
behaviors or appearance may result.
Fast destination
clear Outputs from texture filtering and pixel shading activities
are sent to rendering target destination buffers. S3
Graphics hardware can quickly respond to a DirectX
application’s request to clear a destination buffer by
providing a hardware-assisted fast clear mechanism for
the clearing operation. Efficient clearing of the
destination buffers helps speed target rendering.
Setting options include:
Auto (default) – Select Auto if you want S3
Graphics software to own the decision whether it is
appropriate to use hardware assisted fast clear of
the destination buffer. Hardware assist is usually
enabled (ON).
ON – Select ON to force use of Fast Destination
Clear for optimum performance. All requests to clear
the destination buffer are done through hardware.
This will usually speed rendering, and is the
preferred setting. If an application has display issues
with the fast clear, then you may wish to disable this
feature to improve visual quality for that specific
application.
OFF – Select OFF to disable Fast Destination Clear.
Requests will use a traditional method and clear the
whole destination buffer. This will result in a slower
clearing cycle, but may resolve unexpected visual
quality issues.
Fast Z + Stencil
clear This option can be used to enable or disable the use of
S3 Graphics’ hardware-assisted fast clearing
mechanism for the Z and Stencil buffers.
The Z buffer is an area of video memory which stores a
User Guide for Chrome 400 Series Graphics
SG192-C.1 10/17/2008
Page 115
3D object’s value on the Z (depth) axis. S3 Graphics
software decides whether to make certain components
of an image visible or hidden to the viewer, based on
values in the Z-buffer.
The stencil buffer holds additional information for each
pixel about whether or not to draw it. Stencils can be of
any shape and can be thought of as a mask with cutouts
that allow an image to be seen through the cutout.
Stenciling is particularly useful in creating special
volumetric effects such as shadow volumes from
multiple light sources. The stencil buffer must interact
closely with the Z buffer.
Hardware assist speeds the clearing of the Z and Stencil
buffers for more efficient rendering.
Setting options include:
Auto (default) – Select Auto to allow S3 Graphics
software to own the decision whether it is
appropriate to use hardware assisted fast clearing of
the Z and/or Stencil buffers. Usually Fast Z clear is
enabled (ON).
ON – Select ON to force Fast Z clear to always ON,
so that all requests to clear the Z and Stencil buffers
will always be processed through hardware. This will
usually speed rendering, and is the preferred setting.
OFF – Select OFF to disable hardware Fast Z clear
and to force clearing of the Z and Stencil buffers
using traditional methods. This will result in a slower
clearing cycle, but may resolve unexpected visual
quality issues. If you suspect an application has
quality issues with Fast Clear, then you may try
disabling this feature to see if it improves visual
quality for that specific application.
Detail level adjust The number of levels or steps available for use between
the largest and the smallest MIP map image can be
specified by applications and driver software. Called the
MIP map Level of Detail (LOD) bias, settings are
selectable and can produce results ranging from high
speed performance to high visual quality.
“MIP mapping” is actually an abbreviation for the Latin
phrase Multum im Parvum, which means “many in less.”
MIP mapping textures will increase quality and detail by
generating and storing scaled versions of a texture
image. When the texture is rendered in a 3D scene, MIP
User Guide for Chrome 400 Series Graphics
SG192-C.1 10/17/2008
Page 116
map levels computed by trilinear texturing are available
for use by the Direct3D application.
High quality images will be sharper and more aliased
and will result from the use of a higher number of MIP
map levels. Blurrier images result from using a smaller
number of intermediary MIP map levels. Because less
texture data is used, higher performance is associated
with fewer MIP map levels.
Setting options include:
Auto (default) – Select Auto to let S3 Graphics
software provide optimized control of adjustments for
Level of Detail bias.
0 (Quality) – Select 0 (Quality) to use the highest
available visual quality, using the maximum Level of
Detail bias. This number tells S3 Graphics software
to use the highest number of MIP map levels
possible. This setting will produce the greatest level
of visual quality and detail, but will often have a
significant impact on rendering speed, as much
texture data is processed.
1, 2, 3, 4, 5, 6, 7…– Select any intermediate level to
achieve your optimal balance between quality and
performance.
8 (Performance) – Select 8 (Performance) to tell S3
Graphics software to use the smallest number of MIP
map levels available. This setting will produce higher
speed performance at the expense of visual quality.
Max depth buffer
size Use this setting to control the maximum precision
available for the Depth Buffer (Z buffer). Visual quality
increases with the greater precision available when
using higher bit buffers. There may be a slight
corresponding decrease in rendering speed.
Setting options include:
By App (default) – Select By App if you want S3
Graphics software to provide the depth buffer size
requested by the application. This is the default.
16-bit – Select 16 for force a 16 bit depth buffer.
Applications may request a 16 bit depth buffer. This
depth will provide the fastest rendering speed.
Because this is the least precise format, it has the
potential for decreased visual quality, especially by
creating surface artifacts in distant objects.
24-bit – Select 24 to force a 24 bit depth buffer,
which would be a buffer with single precision floating

32-bit – Select 32 to force a 32 bit depth buffer. The
32 bit depth buffer will provide the greatest level of
precision possible, using a standard single precision
floating point format. While this buffer precision will
provide high visual quality, rendering speed will be
slower.
Note: Forcing a buffer depth may produce noticeable
artifacts. For example, if precision is degraded by
substituting a 16 bit depth buffer, artifacts would be
visible in the resulting images.

Wait for monitor
sync Sometimes called Wait for Vsync, this option controls
whether or not buffer swaps and other activities should
be synchronized to the display’s Vertical Synchronization
or Vertical Retrace Signal and blanking period, during
which the display blanks as it retraces its way from the
bottom right to the upper left corner of the screen.
Setting options include:
By App (default) – Select By App if you want the
Wait for monitor sync setting to change on
application requests. If Vsync OFF is requested, the
back buffer is flipped without waiting for vertical
retrace. If the application requests VSync ON, then
the back buffer is flipped while in vertical retrace.
ON – Select ON to always force a wait for monitor
sync. This option will reduce “tearing” artifacts.
Synchronizing with the vertical retrace constrains the
frame rate so that it does not exceed the refresh
rate.
OFF – Select OFF to allow buffer swaps to be
processed without waiting for vertical
synchronization. When a buffer flip occurs at a
different time than during the vertical blanking period,
visual artifacts, often described as “tearing” or
“shearing” may be apparent. Note that while visual
artifacts will probably occur with this setting, the
frame rate may increase.
Anisotropic
filtering Anisotropic (which means non-uniform shape) filtering is
a filtering technique more advanced than trilinear, which
is useful for quadrilateral shaped and angled areas of a
texture image. A shaper image is accomplished by
interpolating and filtering multiple samples from one or
User Guide for Chrome 400 Series Graphics
SG192-C.1 10/17/2008
Page 121
more MIP maps to better approximate very distorted
textures. Anisotropic can be used in conjunction with
bilinear or trilinear filtering as well as MIP map filtering.
While trilinear filtering is capable of producing fine
visuals, it only samples from a square area, which is not
the ideal sampling area for all cases. Anisotropic filtering
averages sixteen texture samples, or taps, in a non-
square, rectangular or parallelogram shaped texture
sampling pattern whose length varies in proportion to the
orientation of the stretch effect. This sampling rate is four
times the sampling level of bilinear filtering and twice the
sampling level of trilinear filtering.
Textures applied to a sloped surface will not look fuzzy,
which is especially useful when rendering shapes with a
high degree of surface tilting in the X-Y-Z planes. Full
use of the anisotropic filtering capabilities may impact
performance.
Setting options include:
By App (default) – Select By App if you want S3
Graphics software to use the anisotropic filtering
level requested by the application. Not all
applications request anisotropic filtering, and S3
Graphics software does not perform anisotropic
filtering unless requested. This is the default.
OFF – Select OFF to force anisotropic filtering to be
always off.
2X – Select 2X to enable anisotropic filtering at its
lowest level. With this setting, 16 texture samples
(taps) selected from a non-square pattern will be
averaged to generate one texture element (texel)
that is then applied to a single pixel.
3X, 4X, …, 15X – Select intermediate sampling
levels to match your preferred balance between
quality and performance. The higher the sampling
level, the greater the degree of filtering. Visual
quality will improve at the expense of performance.
16X – Select 16X to force use of classic anisotropic
sampling using 128 taps in a non-square sampling
pattern. This level of filtering will produce very high
quality visual output, usually with a decrease in
rendering speed.

Features:
Advanced Warning: Configuration of the following features should
be done only by experienced users, as unexpected
behaviors or appearance may result.
Detail level adjust The number of levels or steps available for use between
the largest and the smallest MIP map image can be
specified by applications and driver software. Called the
MIP map Level of Detail (LOD) bias, settings are
selectable and can produce results ranging from high
speed performance to high visual quality.
Also known as “MIP mapping” is actually an abbreviation
for the Latin phrase Multum im Parvum, which means
“many in few.” MIP mapping textures increases quality
and detail by generating and storing scaled versions of a
texture image. When the texture is rendered in a 3D
scene, MIP map levels computed by trilinear texturing
are available for use by the OpenGL application.
High quality images will be sharper and more aliased
and will result from the use of a higher number of MIP
map levels. Blurrier images result from using a smaller
number of intermediary MIP map levels. Because less
texture data is used, higher performance is associated
with fewer MIP map levels.
Setting options include:
Auto (default) – Select Auto to let S3 Graphics
software provide optimized control of adjustments for
Level of Detail bias.
0 (Quality) – Select 0 (Quality) to use the highest
available visual quality, using the maximum Level of
Detail bias. This number tells S3 Graphics software
to use the highest number of MIP map levels
possible. This setting will produce the greatest level
of visual quality and detail, but will often have a
significant impact on rendering speed, as much
texture data is processed.
1, 2, 3, 4, 5, 6, 7…– Select any intermediate level to
achieve your optimal balance between quality and
performance.
8 (Performance) – Select 8 (Performance) to tell S3
Graphics software to use the smallest number of MIP
map levels available. This setting will produce higher
speed performance at the expense of visual quality.

SECTION 15 GLOSSARY
This glossary includes definitions for only a few of the terms used in the S3
Graphics User Manuals. Numerous on-line glossaries are available if the
graphics term you are looking for is not listed below.
Brightness - Visually, brightness reflects the intensity (or luminance) of the
image going from darker to lighter. In S3 ScreenToys Desktop color, brightness
represents the lowering or raising of the gamma curve. Brightness adjustments
cause all values on the gamma curve to move down or up by the same amount.
Contrast - Visually, contrast reflects the ratio between the lightest and darkest
elements in the image going from low contrast to high contrast. In S3
ScreenToys Desktop color, contrast represents the angle of the gamma curve.
Contrast adjustments decrease or increase the angle of the gamma curve while
keeping the (x, y) point on the curve fixed at (0, 0).
CRT – Cathode Ray Tube. Used in reference to an external analog display
device, the CRT has the 15-pin VGA connector as its standard interface.

DVI - Digital Video Interface, is a high-speed digital connection for visual data
types that is display technology independent. DVI provides digital and analog
support in a single connector and allows for plug and play through hot plug
detection, EDID and DDC2b. DVI is often used to describe a detachable flat
panel display device.
Gamma -- Gamma is the brightness of a display adapter's output. In practice,
gamma is differentiated from brightness and contrast by the way it affects the
adjusted output. Gamma adjustments do not change the bottom left point and the
top right point of the gamma curve. In the S3 ScreenToys Desktop color, the
Gamma slider allows you to adjust the gamma within a pre-determined range.
The value reported on the slider is relative and does not report an actual gamma
value.
HDMI – High-Definition Multimedia Interface is an uncompressed, all-digital
audio/video interface between any audio/video source, such as a set-top box, PC,
DVD player, or A/V receiver and an audio and/or video monitor, such as a digital
television. HDMI transmits all ATSC DTV standards and supports 8-channel
digital audio.

Multi-Monitor – A Windows feature that allows multiple video cards to be active,
each one displaying a portion of the entire desktop. Support for two monitors can
be accomplished through the use of either two separate or one dual head
adapter. With two separate display adapters, there are two separate drivers
driving the separate displays, with each one displaying a portion of an extended
desktop. Dual Head adapters, such as S3 Graphics GPUs, simulate the
presence of two video cards with a single chip.
Primary View, Primary Monitor, Primary Display -- The Primary View display
is the display that holds the logon dialog box when you start the computer. This is
the display used for prompts and pop-up windows. Most programs will display
windows on the Primary Display when you open them. DirectX, Direct3D and
current DVD applications typically run full screen on the Primary Display. In
SingleView Clone mode all active display output devices are associated with this
Primary View.
Secondary View, Secondary Monitor, Secondary Display – A secondary
display may be any display monitor that is not the Primary View in a dual display
Multiple Monitor configuration. Once you select "Extend my Windows desktop
onto this monitor", the Windows desktop is enlarged and extended onto the
secondary display.
Once in extended desktop configuration, the Control Panel "Display Properties"
application allows you to select separate screen resolution and color quality
settings for the secondary display.
YUV – A color encoding format used to transmit color video images. YUV uses
less bandwidth than the three separate video signals in an RGB video
transmission. The two major components of YUV are:
Luminance (Y), or the brightness of an image pixel.
Chrominance (UV or CrCb), or the color of an image pixel.
