I have a mitsubishi dlp WD-60638 and a radeon hd 6800. My tv works with checkerboard 3d via the glasses and emitter I got. I have not been able to get it to output from my computer to the tv. I have a ps3 and am going to buy a 3d blu-ray to try that and double check the glasses work. Any suggestions I should try to get the computer to output? I have tried Tri-Def on all the different settings but their doesn't seem to be a checkerboard output from them.
