Windows Vista Doesn't Work with VGA to HDMI Converter Box

January 9, 2009 11:46 AM

We have an HP Slimline machine running video with an Nvidia Geforce 6150 SE graphics card. We are wanting to use a VGA->HDMI box to convert the video output of the desktop and connect it to our television:

1) We know the VGA->HDMI box works correctly.

We tested with an Asus EEE Laptop running Windows XP and the video successfully outputs to the TV.

We tested with a Macbook Pro laptop and the video successfully outputs to the TV.

2) We know the HP Slimline desktop works sometimes.

When we boot up the desktop the 'HP INVENT' splash screen shows on the tv.

Then, the green status bar with 'Microsoft Corporation' displays.

Then, something happens to the video and the signal stops. I'm guessing that once the boot begins and then Vista settles in something is interfering with the signal being sent to the the VGA->HDMI box.

Any ideas? Thanks!

I found this previous thread but I think we're a bit further along in our testing.

My guess would be that your resolution settings for the HP are incompatible with either the VGA->HDMI box, or with the television itself.
