I decided to update my 9400m's drivers (08 fall unibody macbook) for Windows 7 to the latest available release - 270.61. It went fine, but I plugged in my Display port to HDMI adapter and my plasma didn't receive any signal. My macbook monitor went black, but the tv started its "no signal" countdown after a few minutes, which means nothing is being sent from my macbook to the TV at all.

I tried the Force TV output setting - no dice
I tried to force display detection and some other stuff - nothing

I went back to my mac partition - everything's fine, output fine as usual

I went back to Windows 7 and uninstalled the drivers, then let windows install its stock drivers for the 9400m, which is 177.16 or something. - worked fine again.

Is this a known issue with these drivers? Anything ideas on how to fix it? It seems to work fine otherwise.

Thanks for any help

Sometimes updating drivers in Windows causes problems as you found out. Here's where the old adage goes without saying.... "If it's not broken, don't fix it".

Is it a known issue with the new drivers? Who knows... But if the old ones work, I wouldn't worry about it.

Yeah, seems like a lame unfixable driver thing. I'm gonna hunt down the newest release I can use without having to stick with the very basic stock drivers.
