This chip is similar to the , but it also includes XRAM support and supports the higher dot clocks of the In its current form, X can not take advantage of this second display channel. In this way the expensive operation of reading back to contents of the screen is never performed and the performance is improved. The four options are for 8bpp or less, 16, 24 or 32bpp LCD panel clocks, where the options above set the clocks to 65MHz. The whole thing is divided by the bytes per pixel, plus an extra byte if you are using a DSTN.

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. As mentioned before, try disabling this option. The driver is capable of driving both a CRT and a flat panel display. The following options are of particular interest to the Chips and Technologies driver.

If you get pixel error with this option try using the ” SetMClk ” option to slow the memory clock. Hercules Graphics Card Drivers 2 models. This can be fixed by using tecj ” 18BitBus ” option.


This option is only useful when acceleration can’t be chipps and linear addressing can be used. This might cause troubles with some applications, and so this option allows the colour transparency key to be set to some other value.

This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card. Alliance Semiconductor Graphics Card Drivers 30 models. This can be found from the log file of a working single-head installation. You are probably using a dot clock that is too high or too low ; it is also possible that there is interference with a close MCLK.

So for the various Chips and Technologies chips the maximum specifications are. In fact the timing for the flat panel are dependent on the specification of the panel itself and are independent of the particular mode chosen.

If you are inexperienced with oci Hitachi device drivers manually, we highly recommend downloading the Hitachi Graphics Card Driver Utility.

Information for Chips and Technologies Users

This is the first chip of the ctxx series to support ppci programmable clocks. The total memory requirements in this mode of operation is therefore similar to a 24bpp mode. A sample of an incomplete ” xorg. This might further reduce the available memory.

For this reason a mode that is as close to VESA like as possible should be selected.

Dual refresh rate display can be selected with the ” DualRefresh ” option described above. Use caution with this option, as driving the video processor beyond its specifications might cause damage. So using this option disables the XVideo extension.

Hardware cursors effectively speeds all graphics operations as the job of ensuring that the cursor remains on top is now given to the hardware.

In addition the device, screen and layout sections of the ” xorg. Try deleting theses options from xorg. Drivers are the property and the responsibility of chipe respective manufacturers, and may also be available for free directly from manufacturers’ websites.

In general there are two factors determining the maximum dotclock.

So with the ” Overlay ” option, using the gech SetMClk ” option to reduce the speed of the memory clock is recommended. This is correct for most modes, but can cause some problems. Work is underway to fix this. There has been much confusion about exactly what the clock limitations of the Chips and Technologies chipsets are.
