why does the projector show a second screen with my mac book?

***LC***

I own a Mac Book Pro and use keynote instead of power point, when i connected the adapter for a presentation at my colleges class projector instead of the keynote screen it showed the practice screen, how can I fix this for the future? It was as if there was a second screen , in other words my computer screen was showing what the audience was supposed to be viewing and they were looking at the practice screen that i was supposed to be looking at. Can anyone help me? Please

Answer
Open up Keynote's preferences. Under the Slideshow tab, select âPresent on secondary displayâ

problem connecting macbook aluminum to projector?

Ms.Justice

I connected my mac to a projector and I opened my Keynote presentation. I put the slideshow on but the projector is projecting the two little boxes with my keynote presentation slides. one is the present slide and the other box if what the next slide is going to be??? what do I do to make the projector project a fullscreen slideshow of my keynote presentation.

Answer
Click on the Help menu in Keynote and type PROJECTOR into the search field. You'll see several choices, including the text that I've pasted below.

Your issue seems to be a "mirroring" vs. "dual display" issue.

Viewing a Presentation on an External Display or Projector

Seeing your slideshow and presenter information (notes and a clock, for example) on one screen, while viewers see only the slideshow on a different screen, is called a dual display configuration.
You canât use a dual display configuration on some notebook computers; you have to play the identical slideshow on both screens (called video mirroring). If you have less than 32 MB of video random access memory (VRAM) on your computer, you may have to use video mirroring to display your slideshow on an external projector. See Configuring Video Random Access Memory (VRAM) and Tips for Using an External Display for more information.
To view a presentation using dual displays:

Connect the second display or projector according to the instructions that came with the display or projector and the instructions that came with your computer.
See Tips for Using an External Display for some setup recommendations.

Choose Apple menu > System Preferences, and then click Displays.
>>> make sure "Show displays in menu bar" is checked = very handy!!
Click Arrange and follow the onscreen instructions.
If there is no Arrange button, your computer detects only one display.

Make sure Mirror Displays is not selected.
Choose Keynote > Preferences and then click Slideshow.
Select âPresent on primary displayâ or âPresent on secondary display.â
The primary display is the one with the menu bar. If you choose âPresent on secondary display,â you can customize what the presenter sees on the primary display. See Customizing the Presenterâs View.

Click Play in the toolbar.
Advance through the presentation by clicking the mouse or pressing the Space bar. See Controlling a Presentation with the Keyboard for other options.

i just bought an infocus lp650 projector for a little under 600.00 is that a good deal?

ernesto o

the projector has only 15hrs on a 2000 hour bulb are these good projectors? thanks ..whats the best projector for this price?

Answer
In Focus make some very good projectors so it's certainly a "brand name".

The LP650 is an older projector originally selling for over $3000. That said, projector prices have dropped in the last couple of years, so a new projector with equivalent performance would be in the $1000 range.

The specs (DLP, 1024x768, 2500 lumens, 800:1 CR, 1.4:1 zoom, component and digital input (M1), 35/33 dB noise) are a bit of a mix today. The digital and component capability are good, so is the high brightness level, but fan noise is a bit high and contrast ratio is weak in today's world (That said the rated 800:1 is quite possibly comparable to projectors today rated at 2000:1 or even more due to the lack of standard methadology).

I can't comment whether the DLP colour wheel speed will be high enough to minimize the possibility of inducing "rainbow effect" (look elsewhere on the site at the 1st link for further info) if you are susceptible. Older projectors sometimes had slow wheels (less than 4X) that increased the chance ... but most people are not particulelry sensitive, so it may be entirely a non issue. On a positive point DLP projectors arguably have better longivity than LCD projectors.

Yoiu could probably get a projector with 800x600 resolution for $300-$400, but what you have is a name brand projector, that should work well in a home theatre environment (depending on video processing capability ... but IF are well respected in general).

Considering a new lamp is $550 from at least one source (2nd link), I think you got a fair deal (It wouldn't have been if it were an old lamp). That said ... read the 3rd link on how to maximize lamp life.

What Home Theatre Projector has the cheapest bulb to replace?

Clayton A

I would like to purchase a projector with at least 800x600 that has a bulb replacement cost of under $100.
A friend told me that such a projector exists, but have yet to find it.
I also would like the projector to be less than $600.

Answer
I would like to find a cheap bulb for replacement too. Just hope mine never needs to be replaced. As far as you wanting a projector under $600, just remember you get what you pay for. I'm sure you can find one but don't plan on having good results from it.
