I presently did a fresh installation of Vista Business Edition on my IBM Thinkpad T42.Previous to this I was running Windows XP Service Pack 2. I had a double display by means of my second monitor associated to the VGA port on my ThinkPad. On the other hand, in view of the fact that installing Vista, I am not capable to acquire a dual display. At what time I go to the Control Panel / Display options, the window that frequently shows a diagram of together monitors side by side by means of a large "1" as well as "2" is only displaying one monitor. It appears the second monitor is not even being detected.The outside monitor is certainly associated as well as in working condition; at what time I unplug it in the screen changes to the "Self Test Feature Check".Any suggestion on what this could be? Is there some information I may possibly give that would be helpful in diagnosing this?Thank you in advance for any valuable suggestion.
