How to connect an HP laptop to a projector to show a movie?

by alan-rj / October 16, 2008 7:48 AM PDT

I have an HP Pavilion dv1145ea widescreen laptop (running XP Home with service pack 3) which I am trying to connect to a digital projector in order to show a DVD movie at a public meeting tomorrow (that's on Friday 17 October in the UK). Apparently some computers connect easily, but not this one, although somebody else managed it, so I know that it's possible!

I can only get wallpaper to show on the projector screen at present. I was told by HP Total Care that in Control Panel - Display - Settings I should choose Multiple Monitors, with Screen 1 res 1280 x 768, both boxes ticked; and Screen 2 res 1024 x 768, bottom box only ticked.

When I double click the two screens to confirm their identify they both identify as Screen 1, and screen 2 shows default monitor instead of multiple monitors. The projector screen shows either blank or wallpaper. Just once the projector screen showed identity 2, but I don't know how I got there, and it didn't go so far as to show either the icons on the desktop or Windows Media Player.

I think that at some point I should hit either f5, or fn + f5. When I tried that the former had no effect and the latter sent the laptop into a standby routine.

Any help overnight would be very much appreciated

Maybe I'm missing something

When you say "wallpaper" do you mean your laptops desktop wallpaper? You should see that as well as your desktop icons. If you see part of your desktop and not all of it, I have to think the resolution and or refresh rate isn't quite compatible with the projectors. Did you try to put a DVD in and see what happens? I also know some laptops have a key combination to turn on/off the external VGA connector. Some allow simultaneous output to both projector and laptop screen and some do not.

Connecting a projector to a laptop

Thanks for your reply. Yes, I mean desktop wallpaper. I could try a different res, I don't know how to change the refresh rate. I know my laptop doesn't allow simultaneous output on two monitors, but I've never heard that a kep combination is needed to turn on the VGA connection (other than f5).

Changing refresh rate
by orlbuckeye / October 16, 2008 10:50 PM PDT

Go to display properties under the settings tab and click the advanced tab then click monitor. There is a drop down for screen refresh rate. This is for XP. It should be similar for Vista.

Sounds like you're almost there

You should see your desktop projected if that's what shows on the laptop. It sounds, however, that you're not getting the full screen display and it could be a problem of aspect ratio. Perhaps switching to a 4:3 format rather than wide screen will work. You may need to reduce the resolution a bit too. I would try inserting the DVD if you can get the desktop wallpaper to display. You're playback software may have some adjustments as well.

Thanks a lot for all these suggestions. I've still got the hired projector for a day, so I'll try them a go tomorrow! I was fortunate to find a friend at short notice to give the presentation on another setup.

Light bulbs you shouldn't buy

There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
