Basically, I've got a BenQ XL2420T as a 1080@120Hz monitor. AMD doesn't support this sadly.

I also (foolishly) got the active 3D glasses from NVidia.

Is there ANY chance I can get 3D working as just any regular 120Hz monitor and active shutter glasses?

Edit: Also, I'm using a DisplayPort cable right now, switching from my Dual DVI because it was mentioned that it only works with DP/HDMI and HDMI doesn't support 1080@120Hz (for my monitor, at least).

Edit: For clarification, my drivers are updated and I have TriDef, but it complains about no 3D capable monitor. Which is quite frankly true since it's not a true 3D one, but won't the alternating image concept work at all with AMD?

Hey, I just wanted to bump this a bit even though it's in the top spot and I'm still on it. Maybe someone will get back to it (not like the double post really matters)

I've tried using a HDMI cable today, aside from being garbage technology it hasn't allowed me to use 3D on it either. So back to DisplayPort it is.

It is kind of disappointing you know, it's a 120 Hz monitor, other 120 Hz monitors are supported. Why isn't every generic 120 Hz supported? Maybe an AMD dev can get on it and just sneakily add in the monitor, if they ever read the forums.

The big thing with 3D is that it's not really the AMD software, so we don't have a way to sneak in a monitor per se.

With 3D, it's all based on the whole system configuration. You've got TriDef complaining that you don't have a 3D monitor, which is why the 3D signal isn't being sent to the monitor.

The Radeon GPU will just end up generating a 3D signal, via TriDef, and send that out through HDMI/DisplayPort. We did certification for certain hardware because we tested them and they worked without an issue. On your BenQ, they support it through HDMI and say to use any supported glasses, but all of the glasses that they recommend are nVidia. With nVidia glasses (3D Vision/Vision2), they only work with nVidia GPUs.

It's a pain for our users who want 3D glasses from BenQ, but using a Radeon will just result in the nVidia glasses failing (since they need a GeForce), with the monitor saying "I don't see an nVidia, so I'm not 3D", which gives TriDef that "No 3D monitor detected" error.

So it's technically impossible as it is?

I should've known better then.
