With polarizing 3D systems, it's always a combination of issues - polarization efficiency of Z-Screen, screenquality , glases, seating, and Z-Screen settings.
On a typical Real-D installation, glases and screen are fixed issues (unless you have a very bad screen and opt to replace it). The Z-Screen switches light polarity dynamically - and you can adjust the timing for this device to optimize ghosting.
Another issue is that until the End of 2009, special Real-D releases were available which had special 'Ghost-Busting' mastering applied. Now all servers have an option for internal realtime GhostBusting, available through a firmware update, so DCPs in general have no ghostbusting applied in the mastering. The operators should check wether the server firmware is up-to-date and wether the RealD-EQ has been activated to do real-time ghostbusting.
You can not solve all ghosting issues with these measures, but it seems you can get RealD to an acceptable level - unless you have a really bad silver screen.
