For reference, the original image is: Black Point Enhancement slider The Black Point Enhancement control allows you to adjust the range of black values which are displayed in the shadow areas of the whole image. The adjustment lets you expand the value range to make the darks in the image appear more intense (deeper darks) or clip the range to make the shadows lighter (brighter and lower contrast). Move the Black Point Enhancement slider thumb along the bar to the left to decrease the Black Point Enhancement threshold. This will decrease the darkness of the shadows and thus lighten the shadows in the image. Move the Black Point Enhancement slider thumb along the bar to the right to increase the Black Point Enhancement threshold.

These Standard Features and associated settings are available for adjustment. 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 500 Series Graphics SG195-A.1 10/20/2008 Page 111 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 500 Series Graphics SG195-A.1 10/20/2008 Page 112 Features: Advanced Fast destination clear 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. Warning: Configuration of the following fetaures should be done only by experienced users, as unexpected behaviors or appearance may result. 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 500 Series Graphics SG195-A.1 10/20/2008 Page 113 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 500 Series Graphics SG195-A.1 10/20/2008 Page 114 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 User Guide for Chrome 500 Series Graphics SG195-A.1 10/20/2008 Page 115 point without a low byte for the mantissa. 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.

It is available on selected systems running Windows Vista and Windows XP. 11.1 S3 ScreenToys Power Management S3 ScreenToys Power Management has two basic modes for controlling the level of power conservation: Automatic Power Conservation Mode (Default setting) which lets the S3 Graphics software decide the optimal setting for you. Manual Power Conservation Mode which allows you to use a slider bar to change between settings that conserve power (but reduce speed) or increase speed (but use more power). ACCESS: If your configuration supports power management through S3 ScreenToys Power Management, a menu option will be available through the CHROME menu accessible by right click on the taskbar icon, or from the Advanced menu on the S3 ScreenToys window. OPTIONS: S3 ScreenToys Power Management options are applied globally, regardless of display configuration. You cannot adjust settings unless you have selected the Let me change other power plans (Advanced) checkbox. User Guide for Chrome 500 Series Graphics SG195-A.1 10/20/2008 Page 122 System Status Power Source This area shows the current graphics power management status. The power source may be reported as: AC power Battery, or Unknown. If the power source is not Battery, then the Battery and hours remaining options are blank and disabled. Battery remaining If the power source is Battery, then the battery life remaining (as a percentage) is shown. Hours remaining If the power source is Battery, then the time remaining for the available battery power is shown. The time will be shown in hours. If the operating system reports both minutes and hours, then minutes will also be displayed. Current Power Plan This shows the currently selected Power Plan. See below for detail description of the available power plans. Let me change… Click the checkbox Let me change other power plans (Advanced) to disable the Automatic (default) power setting and enable Manual power setting. If power management options are not configurable on this system, this option will be dimmed and not available. Uncheck this option to use the default Automatic settings optimized for your system. When this option is unchecked or when it is dimmed and not available, the slider is not available for adjustment. S3 Graphics software will automatically: provide maximum speed when the graphics engines are active, or conserve power when engines are idle. If your system supports automatic power management, and you have not previously manually specified a preferred S3 ScreenToys Power management power savings setting, automatic power management will be enabled by default. User Guide for Chrome 500 Series Graphics SG195-A.1 10/20/2008 Page 123 GPU Power Settings area When the Let me change… checkbox is checked, you are in Advanced manual mode and the slider bar will be available to adjust and change power settings. A dropdown list will appear along the area’s title bar, which will contain a menu of the available power options. Power source bitmap A bitmap to the left of the slider bar represents the current power source. Power setting slider (Advanced manual mode) In Advanced Manual Power Management Mode, the slider bar is available and allows you to manually change conservation levels. One end of the slider bar is associated with high power conservation and the other end of the slider scale is associated with high performance/speed. Move the slider bar to the left towards the green Power Saver (left) side to conserve power (reduces speed). Move the slider bar to the right towards the red High Performance (right) side to increase performance and speed (and power consumption). When you select a power setting via the slider bar and apply it, S3 Graphics software will remember and restore the specified power setting during normal operation and at re-boot and resume. This setting is applied regardless of your current power source (AC or battery). User Guide for Chrome 500 Series Graphics SG195-A.1 10/20/2008 Page 124 Power Plans Below are the power plans which may be available. Power Saver setting Use the Power Saver setting to reduce power consumption. This setting will reduce speed and may lower performance. Balanced setting The Balanced setting provided the default setting provided by the driver to provide an optimal balance between power consumption and high performance. High Performance setting Increase the High Performance setting by moving the slider bar to the right. Selecting maximum speed will provide maximum speed, regardless of the current power source. When the power source is battery and you have selected the maximum speed setting, you will have maximum drain on the battery. This will significantly shorten the time you will be able to run the system before the battery needs recharging.

User Guide for Chrome 500 Series Graphics SG195-A.1 10/20/2008 Page 139 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. DualView -- Microsoft’s term for extended desktop mode in Windows. Microsoft's definition for DualView is available online at http://support.microsoft.com/default.aspx?scid=kb;en-us;283674 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. User Guide for Chrome 500 Series Graphics SG195-A.1 10/20/2008 Page 140 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.
