Can be this chip a sample? I check the codes on the internet and other chips seems to have only B, B2, A Thank you. The DKPCI board (versions A, B, C) includes a number of resistor installation options allowing GPIO pins from the F or B devices to perform. This manual is copyrighted by Chips and Technologies, Inc.

This will prevent the use of a mode that is a different size than the panel. This disables use of the hardware cursor provided by the chip.

The x and WinGine chipsets are capable of colour depths of 16 or 24bpp. This manual is copyrighted by Chips and Technologies, Inc. So using this option disables the XVideo extension. This option might be used if the default video overlay key causes problems. This might cause troubles with some applications, and so this option allows the colour transparency key to be set to some other value. For the chips either using the WinGine or basic architectures, the chips generates a number of fixed clocks internally.

Gamma correction at all depths and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets. Typical values for the size of the framebuffer will be bytes x panelbytes x panel and bytes x panel. Dual refresh rate display can be selected with the ” DualRefresh ” option described above. If you see such display corruption, and you have this warning, your choices are to reduce the refresh rate, colour depth or resolution, or increase the speed of the memory clock with the the ” SetMClk ” option described above.


You can use the ” SetMClk ” option in your xorg. This might make certain modes impossible to obtain with a reasonable refresh rate. It is also possible that with a high dot clock and depth on a large screen there is very little bandwidth left for using the BitBLT engine. However use caution with these options, because there is no guarantee that driving the video processor beyond it capabilities won’t cause damage.

XFree86 believes that the 8bpp framebuffer is overlayed on the 16bpp framebuffer. It is enabled by default for machines since the blitter can not be used otherwise. Work is underway to fix this. Before using this check that the server reports an incorrect panel size. Try a lower dot clock.

This option sets the centering and stretching to the BIOS default values. So the driver will attempt to round-up the virtual X dimension to a multiple of 64, but leave the virtual resolution untouched. The and have a 64bit memory bus and thus transfer 8 bytes every clock thus hence the 8while the other HiQV chipsets are 32bit and transfer 4 bytes per clock cycle hence the 4. Using these should give you all the capabilities you’ll need in the server to get a particular mode to work.

Restricted Rights Legend Use, duplication, or disclosure by theand Computer Software clause at This is a debugging option and general users have no need of it. Otherwise it has the the same properties as the However there are many differences at a register level.


For instance, the line. By default it is assumed that there are 6 significant bits in the RGB representation of the colours in 4bpp and above. The HiQV series of chips doesn’t need to use additional clock cycles to display higher depths, and so the same modeline can be used at all depths, without needing to divide the clocks.

The ct supports dual-head display. Email to friends Share on Facebook – opens in a new window or tab Share on Twitter – opens in a new window or tab Share on Pinterest – opens in a new window or tab.

Note that this option only has an effect on TFT f655500. Products are the latest production date, pictures are unable to update, please forgive me. The xx chipsets can use MMIO for all communications with the video processor. For the HiQV series of chips, the memory clock can be successfully probed.

Vcc33 mm Contact QQllb31 B powertip This has a different effect depending on the hardware on which it is used.

Some machines that are known to need these options include. The whole thing is divided by the bytes per pixel, plus an extra byte if you are using a DSTN.
