These options can be used to force a particular clock index to be used. Using this option the mode can be centered in the screen. At this point no testing has been done and it is entirely possible that the ” MMIO option will lockup your machine. The forms given below are the preferred forms. Using this option the user can override the maximum dot-clock and specify any value they prefer.

The four options are for 8bpp or less, 16, 24 or 32bpp LCD panel clocks, where the options above set the clocks to 65MHz. For LCD screens, the lowest clock that gives acceptable contrast and flicker is usually the best one. This option, selects an 18 bit TFT bus. A sample of an incomplete ” xorg. The reason for this is that the manufacturer has used the panel timings to get a standard EGA mode to work on flat technolovies, and these same timings don’t work for an SVGA mode.

In fact technloogies timing for the flat panel are dependent on the specification of the panel itself and are independent of the particular mode chosen.

In general there are two factors determining the maximum dotclock. This shouldn’t affect higher depths, and is fixable with a switch to the virtual console and back. These options can be used to force a particular clock tedhnologies to be used. The order of precedence is Display, Screen, Monitor, Device.


Try reducing the amount of memory consumed by the mode. For this reason a mode that is as close to VESA like as possible technologiess be selected.

It might affect some other SVR4 operating systems as well. However, 8 and 24 bit colour depths seem to work fine. Secondly, the memory bandwidth of the video processor is shared between the two heads. Try a lower dot clock. This is a debugging option and general users have no technologiees of it.

Information for Chips and Technologies Users

When the size of the mode used is less than the panel size, the default behaviour of the server is to stretch the mode in an attempt to fill the screen. WW Memory bandwidth requirements exceeded by dual-channel WW mode. XFree86 releases later than 4. However, some machines appear to have this feature incorrectly setup. For some machines the LCD panel size is incorrectly probed from the registers. The driver is capable of driving both a CRT and a flat panel display.

This disables use of the hardware cursor provided by the chip. However careful use of this option might boost performance. Note that this option only has an effect on TFT screens. Also the maximum size technologiss the desktop with this option is x, as this is the largest window that the HiQV multimedia engine can display.


It also has higher limits on the maximum memory and pixel clocks Max Ram: The Xserver assumes that the framebuffer, if used, will be at the top of video ram. The default behaviour is to have both the flat panel and the CRT use the same display channel and thus the same refresh tfchnologies.

Gamma correction at all technooogies and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets. There is no facility in the current Xservers to specify these values, and so the server attempts to read the panel size from the chip. Using this option the user can override the maximum dot-clock and specify any value they prefer. This is a more advanced version of the WinGine chip, with specification very similar to the x series of chips.

This problem has been reported under UnixWare 1.
