When I connect my unibody macbook pro to my old tv using a vga to tv converter, my computer doesn't even recognize the disyplay.

This is a step by step instruction: MacBook Pro 15 Unibody Mid 2010 Optical Drive Replacement

Did you check the cabling correctly

You may find that as Mac uses a different standard for VGA output, the sync will be on a different pin not recognized by the TV.
You may need to purchase a Mac to IBM adapter from a computer store.
Hope this helps.

Hi

I suggest you to change the setting of display setting in properties.

Thank you

On the MacBook, check the Displays pane in System Preferences to make sure the settings for the external monitor are correct. It's possible that the system is not recognizing the adapter or it has the wrong resolution setting, so it's not sending out any signal that the adapter can use.

Many of the better DVD players and high-end video game consoles use HDMI. You can use one of those as a test signal generator to check the TV.

You may get better results if you use a DVI-HDMI converter, although you would need to get the DisplayPort to DVI cable. This will avoid converting to analog VGA signals and back to digital again.

You have to go to System Preferences, Display and then choose display, arrangement and then check the box mirror images. If you have done that, and it still doesn't work, then I'm not sure what else to do! I hope that helps.

Go into system preferences, click displays, and make sure your color status is set to millions not thousands.

For these types of projectors if you're planning to hook it up using you MacBook ;

You will need a converter ( from VGA to DVI )
Using the VGA cable that came with the unit when purchased ;

Connect the VGA cable on the back of the Projector and on the other of the cable you will connect the converter ( VGA TO DVI ) since for MAC systems it has DVI ports for monitors not VGA...

You can purchase the converter at any Mac store or any computer shop near you..

Do you have the black unibody Macbook Pro that was just released, or the silver model?

Since the display is DVI, it will directly hook up to the silver model. If you have the new model, you need a mini DVI to DVI adapter.
