'Lo there to all! I Recently bought and created a new computer, and made the switch from Nvidia to ATI (6870), and found that my monitor wouldn't run at 1920x1080 resolution from changing the GT 240 to 6870. Still don't know why, but I've put it down to being incompatible. (it puts my refresh rate down to 30i hz, and displays the "out of sync" message.) Anyway, not here to whine about that, the main thing is that since I'm probably going to get a new monitor, I've been reading up on 3D, and decided to go for it. My only annoyance is I can't seem to find any good monitors compatible with ati cards, most are nvidia based, and the monitors I do find are not at 1920x1080 resolution. Any ATI users or non users but knowledgable fellows that run 3D that know any monitors running at 1920x1080 resolution? My only other alternative is perhaps to take the card back and ask to swap it for a 460, and I don't know if that's at all possible! Sorry if I seem mis-informed at all, I'm not entirely up to date with everything and I Was out of employment for a while and forgot what it was like to have cash to spend \o/
Silly question, but have you installed drivers for your 6870? Without drivers, you're not going to be able to really use your graphics card.
If you still want to buy a new monitor, any 120Hz monitor should be 3D-compatible, although I don't know if ATI actually has anything like nVidia's 3D Vision.
tl;dr there's no such thing as a monitor only compatible with certain brands. Make sure you have your ATI graphics drivers installed.
As far as I know the situation hasn't changed - on paper AMD's cards support 3D, but you will need a proprietary technology to support it. If you really want 3D, from what I know it's much simpler to have an NVidia card. So my recommendation would be to sell that 6870 and get a 470. But any monitor that has a refresh rate high enough will do 3D video. It's not really an implementation at the monitor level; all it has to do is make sure it can refresh the frames fast enough.
For the monitor problems, you should make sure that there are no other traces of the Forceware drivers left - use Driver Sweeper or something in Safe Mode to make sure before you install the Catalyst ones.

Like Zam... I mean Mastershroom... said =p, have you installed the ATI Catalyst drivers? Your problems sound like the classic signs of not installing drivers.
Get them here, just select your windows version: Downloads
Thanks for the advice guys, but it wasn't the drivers. I've deleted/reinstalled multiple times. When I go to adapter properties and list all models, 1920x1080 is only selectable with 30hz interlaced and it won't support that. Got a post from someone on tech support forums about that: "The two DVI ports on the card (and this is not disclosed and very hard info to come by so please spread it) are not identical; only one (the one near the HDMI output) is DVI-I (capable of VGA compatibility and vertical frequencies of over 60Hz). The other one (the one by the grille) is DVI-D, not compatible with VGA (so you cannot put any VGA monitor on it, it will not detect it) and locked at 60 Hz ( so one cannot put a 120Hz gaming LCD monitor on it either). The card is crippled by design. Please don't no one give me noob talk that for LCDs the refresh rate does not matter, because it does - you have to enable VSync to avoid screen tearing and once you do your FPS is locked to your monitor refresh rate just as in good ole CRT times. I have just returned my Sapphire HD 6870 because of this. See here : http://www.hisdigital.com/UserFiles/product/AMD_Radeon_HD_6850_6870_ENU.pdf search for DVI-D in the text. " So keep that in mind any considering going for a 6870 themselves. Sigh, it looks like I'm returning it, hoping to swap it for a 460 and I'll be absolutely raging if he won't accept it back. Is the price difference from a GT 460 to 470 big? The Sapphire HD 6870 cost me £210. Wonder whats best
