I Can't Get a Picture when my Mac is Connected to my Vizio HDTV, in Windows Mode..

[HappyDude20]

I have a MBP 2009 and can't get a picture on my Vizio HDTV when connected and its in Windows mode..w/ Snow Leopard its fine and automatically connects but not with Windows.

I should mention I have Windows XP on my Mac, not Vista or 7.

This is driving me crazy.

Even if I'm in Snow Leopard on my Mac and its connected, when I switch on the Mac to Windows, the HDTV goes blank...or blue rather, saying no connection.

Any help is highly appreciated. Obviously this is something w/ Windows and hope someone could shed some light on the subject.

Thanks!

I seem to recall hearing that windows is not completely compatible with Mac hardware with the EFI translation and all that (I could be wrong). How are you using windows eg boot camp or parallels etc.?

And what adapters/input are you using for the connection? (HDMI? VGA? ... )

Hi, i'm using Bootcamp and in terms of cable i'm using...

http://www.bestbuy.com/site/Dynex&#...33599&skuId=7003155&st=rgb&contract_desc=null

I call it RGB cable, iono why..i'm assuming this is the correct name...and then that cable connects directly to the back of the TV.

Seems to be a VGA (analog RGB) cable even though the link didn't work for me, I was able to find it by SKU and item name.

Your MBP doesn't have a VGA port, so what are you doing to convert from the MiniDisplayPort connector to the cable you linked to? The Apple adapter?

Who supplied the video drivers you are using? Apple? Microsoft? Nvidia?

Which drivers?

I use that one and a VGA cable to my Samsung TV using the Boot Camp drivers on both my 2008 MB and 2009 MBP.

There were some issues with an earlier adapter and Windows which required modifying the cable to disconnect a pin, so it may be that one of the wires is connected/not connected properly with the Dynex extension cable...

(NOTE: Weird that that is the "right" gender can you actually connect the adapter directly to your TV?)

Have you run Apple Software Update to make sure you have the latest drivers?

Can you skip the Dynex cable and try it with just the Apple adapter connected directly to the TV? This will eliminate the cable as a source of the problem even if it might be hard to do logistically.

EDIT: You could also try the Nvidia drivers and replace the adapter/cable with one of these: http://www.monoprice.com/products/p...=10246&cs_id=1024605&p_id=6004&seq=1&format=2

The Nvidia driver just worked! Thank you so much! This was driving us crazy.
