Fusion displays a big red 'X' in a 2D view when it is unable to display an image.  

(TODO - Add picture of red X)

If you have just installed Fusion, have recently changed your hardware or drivers, or have recently upgraded Fusion you may be experiencing a big red 'X' because:

* Your graphics card drivers are too old.  Fusion makes use of many newer OpenGL extensions which require your graphics card drivers be up to date.  If you are consistently experiencing the red X try updating your graphics card drivers.

* Your graphics card is too old or does not support certain required OpenGL extensions.  Any Nvidia or ATI card that came out by the year 2000 or later should be able to run Fusion, although the newer the card the better.  Having a newer card increases your performance and makes more features of Fusion available.  See the [[Choosing Hardware for Fusion]] section for more information.

* Your desktop is not running in 32-bit color


Other reasons you might be experiencing the red X are:

* You are trying to view a channel in an image that is not present.  This most commonly happens when you have set the view so that it displays Z depth, but the image you are viewing has no Z channel.

* Video card acceleration is turned off on your computer.  This can be caused by an improper/incomplete driver installation or the user manually turning it off.  Video card acceleration can also get turned off if your system hung/crashed due to a graphics problem and ATI's VPU Recover utility was invoked.  Try rebooting your computer.

* There was not enough graphics card memory or RAM available to display the image.  When there are other applications running that are very memory or graphics intensive, Fusion and the other application(s) will compete for system resources with the result that sometimes Fusion will not get the resources it needs.  This can also happen if Fusion is using up a lot of memory that it cannot release - eg. you are doing a very memory intensive render or have created a preview that fills up memory.  To help diagnose if running low on graphics card memory and/or RAM may be the problem, try closing all applications on your computer including Fusion, restart Fusion and attempt to view a small 8 bit Background tool in the view.


If none of the above helps, you can contact eyeon's tech support about the issue.  It would be a good idea to attach your OpenGL Hardware Information to the email.  To produce this information:

1) Hold shift on the keyboard, and right click on the lower right area of the fusion interface that displays memory usage. <br>
2) Choose the Debug: List OpenGL Hardware Info. <br>
3) Save the text that is displayed to a document you can find. <br>
4) Email the document along with other information about your problem to mailto:tech@eyeonline.com. <br>
