Hi,
I'm using a Latitude E6410 with the onboard Intel graphics card. I successfully used the DisplayPort to connect to the HDMI port on my Panasonic Plasma (with a connector) - actually I connected to my A/V Receiver's HDMI port which then pushed the sound to the speakers and the video signal up to the TV's HDMI port. This worked well for some weeks. I'm not sure what I've changed but I know that during the last weeks I updated the Intel graphics driver with the latest one from the DELL website. Now, I don't get anything out of my DisplayPort - no sound, no video. The laptop doesn't even recognize that there is a TV attached.
I already tried to directly connect the laptop to the TV without the Receiver in between - no luck. I tried installing an old graphics driver which came with the installation CD of the laptop (not sure if this was the one that was running before I had the issues) - no luck.
Any help is highly appreciated!
Thanks
Kurt
