Can you set the resolution to something that you know your HDTV will display? Some tvs are restricted on what resolutions and aspect ratios they will display, with the typical behavior being a black screen if the chosen settings are out of range. Same with a regular monitor.

Before you try installing another driver, make sure that you completely uninstall any old video driver you were using before (you can use the cat-uninstaller and DriverCleaner Pro). You can do this in safe mode, then reboot.

If the card is working on normal windows bootup and in safe mode, its likely that only the driver is at fault. Grab a fresh download just to be safe and then install it ( to be safe make sure you select the 4870x2 as your card on the ATI/AMD driver download page).

The black screen can also happen from a bad refresh rate setting.

If none of that works its possible that there is something wrong with the card itself.

Starting by bashing the company isn't going to do you any good, nor is it helpful if you're trying to get advice.

I'm kind of in the same boat here with two 4850's in crossfire. Using a similar method to above with Drive Sweeper in safe mode did the trick to get it up and running properly on the 9.7 drivers, otherwise my monitor would just lose the signal when Windows 7 x64 would boot up.

However, now I was hoping to get 9.8 installed but this method just doesn't want to work. Having the exact same problem. Tried just about every suggestion I could find but nothing seems to make a difference.

Anyone have any other ideas?

you know what, i think there is some hope in your message, i didnt actualy try 9.7 at all and i've been reading its good, i only tried 9.8 which came yesturday
and also the original drivers with the cd (8.6 i think), i'll try driver sweeper and do your method tonight. I realy want to use this card and if i dont fix it in the next 2 days
my wife will leave me maybe because I spent all my recent time after work on this card lol

also, driver sweeper isnt in torrents, do you know a good link? and do you know a good link for W7 64bit as torrent? cheers..

Torrent suck.

Driver sweeper is free, try a google search.

If you cant find Windows 7 torrent your not to smart.

You can get a free trial news server and download apps as fast as you internet goes, no more hours/day long torrents.

On my 20meg connection I download 2300KB/s all day long. Try that with a torrent.

Yeah, drive sweeper is free. Easy to find.

What's funny is that Vista x64 seems to be working just fine with the drivers without having to use drive sweeper or anything. I haven't attempted 9.8 on Vista yet, but 9.7 installed easily without a problem. Update and good to go. Maybe it's something with Windows 7 RC...regardless, hopefully it won't be an issue (or a work-around will be available) once we get the full version in October.

I treat a new driver like a bios. If the driver I have is working, and the 'white paper' on the new one doesn't show inprovement over the one I have, I don't update to it.

As in reference with this thread, if the newest driver doesn't work, try older ones. There is a reason why they provide you with a link to most of the older drivers.
