How come I'm getting ghosting with SBS and TAB but not frame sequential?

[Redd]

I just tried a couple of games with NVIDIA's 3DTV Play (ie: frame sequential) and they displayed just fine without any crosstalk. Then I tried them again with SBS and TAB and insidious crosstalk started appearing, even if I ran them at the same resolution as frame sequential.

Any ideas why that might be? And is there no solution or workaround other than going back to frame sequential (which sadly I can't do)?

Maybe my 3D TV has worse timing when using SBS/TAB than frame sequential, causing some frame blending? I'm using shutter glasses.
