Composite sync on green.
Which is the reason for the drop in the dot clock. The user can force the panel timings to be recalculated from the modeline with this option.

You can use the " SetMClk " option in your xorg. Dual refresh rate display can be selected with the " DualRefresh " option described above.
This option forces the two display channels to be used, wnd independent refresh rates. None of these are currently supported within the driver itself, so many cards will only have limited support.

The " FixPanelSize " can be used to force the modeline values into the panel size registers. Similar to the but also incorporates "PanelLink" drivers.
Note that this option only has an effect on TFT screens. In this case enough memory needs to be left for the largest unscaled video window that will be displayed.

Typical values for the size of the framebuffer will be bytes x panelbytes x panel and bytes x panel. Gamma correction at all depths and DirectColor visuals for depths of 15 or greater with the HiQV series of chipsets.
It also reduces the effect of cursor flashing during graphics operations. For the chips either using the WinGine or basic architectures, the chips generates a number of fixed clocks internally. Using an 8bpp, the colour will then be displayed incorrectly. The server will then allow the mode to occupy the whole x Znd. Many LCD displays are incapable of using a 24bpp mode.

By default the two display share equally the available memory. It might affect some other SVR4 operating systems as well.
If it is a standard mode and frequency that your screen should be able to handle, try to find different timings for a similar mode and frequency combination. This support can be used to give a single display image on two screen with different refresh rates, or entirely different images on the two displays. There has been much confusion about exactly what the clock limitations of the Chips and Technologies chipsets are. Otherwise it has the the same properties as the The effect of this problem will be that the lower part of the screen will reside in the same memory as the frame accelerator and will therefore be corrupt.
It's entirely possible the video RAM is bad.
Before using this check that the server reports an incorrect panel size. This is correct for most modes, but can cause some problems.
Org releases later than 6. This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card. However use caution with these options, because there is no guarantee that driving the video processor beyond it capabilities 655550 cause damage.
The formula to determine the maximum usable dotclock on the HiQV series of chips is. Note that for the this is required as the base address can't be correctly probed. So this limit will be either 56MHz cgips 68MHz for the xx chipsets, depending on what voltage they are driven with, or 80MHz for the WinGine machines. Typically this will give you some or all of the clocks I'd try and drivers if you can find them.
For instance, chjps line.
