Hi,
  One interesting observation I had in testing VMD with some of the new
LG TVs is that although the LG 4K TV supports 6 different stereo modes,
only some of them are usable when the video driver is set for the native
4K display resolution of the TV, at least in my testing with a GTX 980
and driver version 343.22. One potential catch with this is that video
cards using HDMI 1.x outputs may downsample the color information by 2x
or more, converting to so-called 4:2:2 or 4:2:0 color formats.

I think that the downsampled color formats are inherently unworkable with
row-interleaved, column-interleaved, and checkerboard stereo formats,
which in the case of the LG TVs I've been testing leaves only the
side-by-side and over-under video format. The drawback of the
side-by-side and over-under formats is that they only work correctly
with a full-screen window, and clearly that is somewhat limiting.

I'm currently trying to sort out a video driver version that can run
the TV without any downsampling of chrominance information, and I'm hoping
that might allow the LG TVs I'm testing to run at full 4K resolution
while also supporting windowed stereo. If you drive the LG TVs at 1080p,
they do support all of the stereo modes, which is one reason I suspect that
downsampled chrominance might causing the limitation in 4K modes.

Cheers,
