At a distance of 15 meters, Monster showed a marginally better picture quality over the No Name brand. And when I say marginally, I mean that if they hadn't been sitting right next to each other, I would never ever have noticed.
The only "quality difference" you are going to see is bit dropouts in the image called "sparklies". HDMI is a digital signal, the pixel data either gets through or it does not, there is no "in beween" like there is with an analog signal.
With HDMI/DVI (they use the same video signal) and DisplayPort you either get a 100% perfect image or you get an unacceptable image with dropped pixels. There is no "in between" quality at all. It's either good or bad, period.
DisplayPort is much better than the DVI (and HDMI) signal because it's a packet based signal and can work over much longer cables without dropping pixels. The DVI/HDMI signal was designed to be able to drive a CRT display and is basically just a digital VGA signal while DisplayPort was designed for digital panels.
