I found in certain reviews that Dell U2311H is an IPS panel, but is LCD. Also it is superior when compared to some LED back lit TN panels(of course, IPS panels are better). So what exactly is the difference between LED back lit and LCD? Is the difference substantial?
IPS was a huge step forward when they went from TN. Its simply the way they switch "the crystal molecules move parallel to the panel plane instead of perpendicular to it" However TN panels are cheaper to produce. Now Samsung has come out with PLS which is similar to ips? but cheaper to produce. I just ordered an s24a850 and will give PLS a shot.
