Are you sure it's 1080p100 on the link, not 1080p50 and upconverted to 100 Hz internally? The two are quite different - the internal upconversion won't affect the compositor on a PC, and one of the "joys" of consumer targeted marketing is that it deliberately blurs the difference between "1080p100" and "100 Hz display".
I've not seen a TV here that does 1080p100 (in the UK) - most do "100 Hz motion processing" (i.e. upconvert incoming 25/50 fps material to 100 Hz), but I went for an LCD set that does variable frame rate - 23.97/24/25/29.97/30/50/59.94/60 fps, based on what the input is doing - instead of one that upconverts to 100 Hz.
Of course, the ultimate, if we could afford the link bandwidths involved, would be a set where no pixel ever subtended more than half an arc-second on the viewer's eye, and the vertical refresh rate was 300.300 kHz, which is an exact multiple of all the commonly used frame rates.
