I just got a new 3D TV (LG 42LM6700) and have played back some 3D movies using my PS3 fine, they look awesome and the 3D effects are good and get pop out effects on movies that have them.
However I have one or two region locked discs that I need to play back on my PC using Power DVD 12/11 or TMT5 using i5 2500k and Nvidia Geforce GTX 460 GPU.
Last disc I tried was Final Destination 5 and on my PS3 it works flawlessly but on my PC the background of the 3D image is blurry and the subtitles are doubled just like if you was not wearing the polarized glasses.
I do see depth in the picture but all of the pop out effects are missing and there is a slight blur to the image. I have tried both PowerDVD and TMT and same problem on both, got latest video card drivers, using a mini HDMI to HDMI 1.4 cable and got Nvidia 3D settings enabled in the control panel.
