Epson Projector causing presentations to zoom to 400% / max font size
Posted on 2008-10-09
I have a client using a Dell Latitude D820 laptop connecting to an Epson Powerlite 76C overhead projector in a conference room setting.
When running presentations either through Word, Powerpoint, Media Player, Internet Explorer 7.0, etc, etc when working just off the laptop everything works fine. The moment you plug in the projector and do a "Fn+F8" to duplicate the screen onto the projector for presentations everything goes strange. While in Powerpoint all slides zoom to 400%, if you start the presentation and click the mouse to advance the slide it immediately goes back to the first slide. There is also a error sound of a stuck key while the presentation is running. When in Word or Outlook all text in emails and documents changes to max font size (possibly just zooming cannot confirm). When I would go into Internet Explorer to check for updates and driver upgrades the screen would reduce in size to 10% as if I were pressing and holding "Ctrl -" (minus).
After spending about 3 hrs trying to get this working (During a board meeting no less), updating drivers, changing resolutions, verifying no stuck keys, disabling and reenabling devices (ie touchpad/mouse "eraser nub"/mouse from a desktop/keyboard, I ended up plugging the projector back into the 15 pin vga connection, enabling the adapter as an extended desktop. This allowed me to to utilize the "Use Presenter View" in Powerpoint and place the Powerpoint presentation on the 2nd monitor (the projector in question) and temporarily allow my client to go on about his presentations this week. This however is not an "acceptable longterm fix" as he wants to be able to duplicate his screen on the projector so he show videos, etc.
I am completely baffled by this issue to be honest. I've asked all the other Networking guys on my team at my office and not a one of them has seen or heard of an issue remotely like this. The only thoughts anyone has had is that it might be related in some way to handicap accessibility features, but this would effect the laptop when the projector is unplugged as well I would think... it also wouldn't explain the stuck key error sounds either. Another thought was that it was related to display settings for the projector however it will not show in Device Manager or in display settings to adjust anything, but again this wouldn't explain the before mentioned issues even if this were the case. The laptop is running Windows XP SP3 fully patched, Office 2007 again full patched, Internet Explorer 7.0, on a Dell Latitude D820, connecting to a Epson Powerlite 76C Projector.
Any help would be GREATLY appreciated.
