Problem with Sanyo projector and Macbook compatibility

My projector is Sanyo CXVT (LP-Z5) and I wanted to connect my Macbook (Mac OS X 10.5.2) to it. I bought the micro DVI and Video adaptor, tried the video connection for a few minutes it worked, a week later, I bought a S-video cable thinking that it might give me a better quality but this is when the problem started: the picture on the big screen is different from the monitor. I changed the display resolution but no change. I rebooted the computer, no change. When I accidentally moved a Safari window to the right, a part of the window could be seen, seems like the projector and the macbook monitor are showing different windows. Also, I changed the background picture in my computer but no change in the projector. I tried the screen saver, it worked. I also tried the video cable but same problem. Does anyone know what went wrong? What other connection can you recommend? Thank you.

 

How is it different? Perhaps post a photo/screenshot of what the projector is displaying? Also, how are you connecting a S-Video cable to the Macbook?

 

The projector displays the basic Mac screen, I mean the one that looks like an AURORA even if I change the Macbook's screen background. I can see the "System Preferences" window, though on the projector.

I use the Macbook accessory "mini DVI to video" connector which has 2 options: a video and S-video.

 

So it is just the background? Unless you have your external display or project set to clone your Macbook display, it will have a unique background, which you can change by going to System Pref>Desktop and Screen Saver, and then changing it in the dialog box that opens up on your extenral display (not the one that opens up on your Macbook display).

 

No. I wanted to watch a DVD (movie) but the DVD window can't be seen on the projector. I minimized the window and moved it to the right so that half of the window is hidden, and surprisingly, the other half could be seen on the projector (left). It's like a rectangular screen where the left side is shown on the computer monitor and the other half is on the projector.

 

That's the DVD copyright protection kicking in. Occurs in Windows too.

It looks like you're running a dual dual monitor setup. The only way to fix this problem, is to make the projector the default monitor by cloning both screens. At least that's how it's done in Windows.

By the way, I wouldn't use S-Video as a means of connection for your projector. It's horribly outdated.

these are the connections:

HDMI 1 HDMI 2 computer (15pin) video S video component (green, blue, red) D4-video component 2 service port

Which one is the best for computer? Can anyone help me arrange them from the best to worst?

 

I would say:
HDMI
Component
S-Video
Video

 

Which of these can I connect to my Macbook to watch movies? By the way, I have a Mitsubishi DVD player but I bought it cheap (around US$50) and I learned recently that it can't play all DVDs. After I heard about the "blueray" I decided to wait for a while to buy a new player. I'll use my Macbook to play those DVDs that can't be played on my DVD player.

By the way, I think this will be my last question. So, I'd like to thank all of those who took time to answer my questions. You all did a good job. Domo arigato!!!

 

None of them if you don't have the correct adapter. I would suggest you use a mini-DVI to DVI adapter, then use a DVI to HDMI cable to connect from the adapter to your projecter. That way you will get the best image quality and the highest resolution.

You could achieve the same quality using Component, but you will need to purchase a signal converter (since DVI is digital and component is analogue), which will cost you much more than the DVI to HDMI cable.

 

S-video has the worst picture quality. I would say that go with the component (the 14 needle connection) or HDMI.

 

I tried to connect using the video and S-video to our company's big plasma TV same result as the projector... which brings me to a conclusion that we CANNOT connect Macbook and TV/projector using the video and S-video cables. Makes me wonder why they sell them (¥2500 in Japan about US$22)?

 

I asked an appliance store employee, apparently, Macbook has no HDMI connection. True?

 

It doesn't have a direct HDMI connection, but you can get a DVI to HDMI adapter for cheap.
HDMI has combines DVI and audio into one cable, so you can still get HDMI out of a macbook.
