For PCs that are not equipped with HDMI port, it really is the essential product in this price range. A driver exists for Windows 8. I recommend to use the Firefox browser & Flash Player to date; Personally it is through this that I get a smooth picture and a non-jerky sound. On some PCs the sound cuts and only remains that of the third monitor, I have not yet found out why. I recommend this small calculator, it is a good quality / price ratio.
