Actually in this case it would work fine. The Seiki's panel is actually 120hz, the 30hz limit is on the input side. Send it a 24hz HDMI signal and it can easily match that up to the panel's actual 120hz refresh rate by simply showing each input frame for 5 panel refreshes instead of the 4 refreshes it displays the 30hz input at. The Seiki can also take 1080p input at 60hz, which would be a reasonable fallback for gaming. Run 4k 30hz for desktop usage, and 1080p 60hz for gaming.
