Following a Windows 7 update my laptop would no longer recognize my projector, which it had been doing for some years and immediately prior to the update. I also find that my laptop now no longer recognizes my monitor, which again it had been doing for some years. Different cables are used so it is not a cable problem. I have been through all the obvious things and have looked for updates to the graphic driver, but no better updates available.
When I plug either of these items in to my laptop the screen resolution on my laptop changes as if it is recognizing the additional hardware, but in neither case is anything displayed on the remote device.
Can anyone give me some ideas about where to go next with this?
Thanks in anticipation of someone's help.
Thanks for your reply.
Monitor is recognised and I have it set to "duplicate" - there is no mirror option. I have tried this before but still no display on monitor. The laptop seems to recognise the monitor and projector but it just won't show the laptop desktop whatever setting I have it on. Baffling!
