What I meant was that the screen (LCD scanout) is refreshed in 1/144sec; but not at 1/144sec intervals. (can be any variable interval)
So you've got: -- faster delivery (from computer over cable to display) ....AND.... -- faster scanout (refreshing from top to bottom)
Right now, in 144Hz GSYNC monitors, frame scanout occurs in realtime with delivery (scanout occurs as the bits come over the cable, at the full 144Hz-equivalent bandwidth, but not "144Hz intervals"). My XL2411T and VG278H does realtime scanout (~2-3ms input lag for top edge of screen; more determined by the pixel transition time, measured by my own photodiode/oscilloscope), and G-SYNC monitors do realtime scanout as well.
