I have an Optoma GT700, a HTPC with an ASUS Radeon HD 6570 (EAH6570/DI/1GD3(LP)), and an Onkyo HTX-22HDX.
The Optoma and the Radeon are both DLP-Link 3D Ready, and the Onkyo support HDMI 1.4a.
I have the latest Catalyst drivers installed, but not matter what I try, I can not make the 3D options on the Optoma to appear, or be un-grayed.
The Optoma manual mentions 2 places where I should see the 3D settings.
Under the IMAGE menu, and under the Display Mode setting, there should be the 3D option but it does not exists.
Under the DISPLAY menu, there should be a 3D sub menu (with a bunch of 3D settings) but it does not exists either.
The manual implies that 3D is only available when using DLP Link mode, but I see no way to setup DLP Link mode.
The only thing I'm not sure about, is the 25 feets HDMI cable, so just in case I just ordered a new one.
So, besides checking the cable, what else could I be missing here?
