Matrix Mil always reported that no system capable of supporting an Auxiliary display could be found – no matter how I changed the millions of possible settings, the auxiliary display would always fail to initialise – loads of hours\u00a0later I became seriously worried that the Millenium P-Series graphics cards do not provide Auxiliary display support to Matrox Mil!<\/p>\n

Well, it turns out that the P-Series graphics cards do provide Auxiliary display support to Mil, but in order to get it to work (in my case) an update\u00a0needed to be applied to the Matrox graphics card driver – In my case I installed the update contained within m800du09.zip, once applied the Auxiliary display worked just fine!<\/p>\n
\u00a0<\/p>\n
So anyway the moral of this story is that if you’re trying to get an Auxiliary display to work with Mil and you’re getting this error message no matter what you do – get on to Matrox and ask if there are any updates for your graphics card drivers and install them straight away!<\/p>\n

PS<\/strong>\u00a0 As the Mil documentation says, in order to get the Auxiliary display to work you will first have to disable the\u00a0‘dual-head’ functionality of your Matrox graphics card.\u00a0 Now, with the newer Matrox graphics\u00a0software ‘dual-head support’ is no longer called ‘dual-head support’, instead\u00a0go into the Matrox ‘Power Desktop’ settings, and\u00a0set the\u00a0‘Multi-Display Setup’\u00a0option to ‘1 Display (no feature display)’.<\/p>\n \u00a0<\/p>\n PPS<\/strong> It seems that where the Auxiliary display is concerned, the Matrox drivers are not very good at cleaning up their resources when the calling process ends – it is very important that you call MdispFree() on the Aux. display when your process is shutting down otherwise when you try to re-launch the process you will get the above error message every time you try to allocate the display until you reboot your system!<\/p>\n","protected":false},"excerpt":{"rendered":" I ran into a problem while attempting to get an Auxiliary display to work on a Machine Vision system I was developing with a Matrox Solios Frame Grabber and a (dual head) Matrox Millenium P650 graphics card.\u00a0\u00a0The plan was to have\u00a0each vision station (in a Parmacutical AOI setup) output all of the images it acquired […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[79,76,75,78,77,80],"class_list":["post-68","post","type-post","status-publish","format-standard","hentry","category-tech-stuff","tag-aoi","tag-frame-grabber","tag-graphics","tag-machine-vision","tag-matrox-mil","tag-parmacutical"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
