The syncs don't matter much as long as they are long enough, the beam is not visible during sync. In doubt leave them alone. Timing relation wise, the totals matter and can affect screen size an timings. When fixing overscan the should be kept the same. Here is the somwhat simplified precedure to get rid of overscan, assuming you start with a valid timing: Have a coffee, this procedure will take some 15mins.

Now edit the new timing: left overscan of X pixels: increase horizontal back porch by X, decrease horizontal total by same X same for the right side by increasing the horizontal front porch top overscan is reduced by increasing the vertical back porch and decreasing vertical active corespondingly for bottom overscan vert front porch vs vertical active but due to a bug this is fairly limited apple is working on that for reference see What are those syncs and porches, anyways? The modified timing should still have the same syncs, totals and frequencies as before.

Check whether the timing is enabled in the resolution tab. If it isn't, adjust the limits in the monitor tab or register if you haven't done that. Install the new setting and reboot Done. Have some more coffee The horizontal front porch is the right border unused aka black display area. The horizontal back porch is the left border. The vertical back porch is the top border. The vertical front porch is the bottom border. The horizontal sync is the time the beam needs to get from the far right edge back to the far left. The vertical sync is the time the beam needs to get from the far bottom edge back to the top.

The vertical frequency tells you how often the whole display gets redrawn in a second. The horizontal frequency tells you how often a single line gets drawn.

This usually is the most sensitive parameter. The pixel frequency tells you how often a single pixel gets drawn. This usually is the least sensitive parameter and the limit is usually not critical. Back to FAQ Are digital projectors supported? I don't have much experience with those, but some people have tried and had success tweaking the timings for adequate display. Apart from native timings you can also add scaled resolutions resolution scaled by graphics card for varying needs;- Back to FAQ Are LCD monitors supported? But it doesn't make much sense to use anything but the native resolution for these.

However you can use it to fix the timing, if your system doesn't detect it automatically, to get specific frame rates e. In the resolution tab, double click the timing and enter: Back to FAQ Are fixed frequency monitors supported? While this is in principle possible, you can not change sync type to composite or sync on green and you need to know rather precise timing details. If you have the required timing details and the monitor supports separate sync e.

I'd recommend to use a spearate multi-sync monitor without DDC to test the timing and then disable all but the usable timing. The graphic card needs to have proper support for MacOSX.

Is that supported? It uses the normal MacOSX technique of keeping different monitor settings for different monitor types. If you adjust one monitor type, others should not be affected. This is what I'm using all the time:- One catch is that this only works if at most one monitor has no DDC. Usually the iBook is limited to using external monitors in mirror mode. What renders this tool rather useless, since in mirrored mode the usable resolution is limited by the smallest of the involved screens.

However there is a tool to enable non-mirrored mode on iBooks. It doesn't work on all iBooks and can put unsupported iBooks into fairly unfunny modes. Handle with care! Further descriptions and the download are at macparts. Yes, but the build-in monitor is fairly slow maximum 72KHz. See iBooks for whether you can fix that. Either set the applications group ownership to admin and remove all access rights for other users or simply delete the program after using it to later change the configuration simply reinstall the app. If you disable all but the desired resolution you can make sure that no one sets the display into suboptimal modes.

Back to FAQ What resolutions and refresh rates are supported? Apart from standard resolutions there is quite a list of others. They come in many flavors for aspect ratios of , or or others. This is limited by your hardware and difficult to predict. You can check what you'd get yourself before registering.

Some of the resolutions might be more than what your graphic card can handle and will be dropped. Also you can change any resolution into a in manual mode and get near arbitrary combinations.

I'm not sure how those work in X Use these if you suspect a new version contains a new bug. Version 1. In those scenarios the application had no effect whatsoever. Which confused the "Displays" control panel, since there you can only change either the resolution or the frequency at a time. So in effect the bug blocked access to some resolutions that would have worked otherwise.
