Hi guys,

I have a question about connecting my HD3870 512 to an HDTV. I'm using Windows XP pro 32-bit.

Video card:

HDTV:

monitor:

I've had the monitor successfully attached for about a year. I cannot successfully attach the new TV by itself or in conjunction with the monitor. The ATI drivers are the latest versions and i updated the TV software as well.

When the system is starting, both monitors will display the same picture for the POST screen and the Windows XP loading screen. After that, the TV will go blank but the monitor continues to work. I set the properties at 1440x900 60hz for the monitor and 1920x1080 60hz for the TV. Even with that configuration, i continue to get "no signal" from the TV. 1920x1080 60hz is supported by the TV. I've tried lower supported resolutions also with no luck.

If i start in safe mode or safe mode with VGA, i can get the same picture on both screens.

Any ideas? I'm kind of at a loss and spent 3 hours updating and changing settings last night. I'm thinking it's the ATI driver but don't know what else to do with it. :shrug:

I appreciate the help.

i talked with powercolor again and they said it might be the converting cable i was using since it's not ATI licensed. i tried the DVI-HDMI converter included with the card and it didn't make a difference.

i DID have success after running driversweeper though! it was working fine last night with only the TV or also the 19" connected as a desktop extension.

it's back to "no signal" this morning though. :( something is fishy with that ATI driver.

You're correct, it's definitely a Windows driver issue. Be sure you have the latest driver and Catalyst Control Center. I actually just purchased a DVI-HDMI cable to go from my HD3870 to my 46" Samsung HDTV (crossing fingers for no issues). Be sure you have the latest software for it, and if all is well on your pc, see if there's a firmware for your TV that might fix a common issue with it. I'm not sure how old that particular model is, but if it's relatively new, I wouldn't worry about the TV.

FYI - be sure to use ATI's control center and adjust the settings through that. That's where you select resolution and i vs. p. Be sure to use p ;) but I'm sure you knew that. Good luck!
