I bought the 322pf to work with an HDMI digital microscope but haven't used it enough to comment on quality. I would have prefered something a bit smaller for the job but happy with the smooth rounded/enclosed back panel and the price couldn't have been better. I'm still using my HP L2445m desktop monitor I bought when it first came out around 2009. I've used it every day since, sometimes for hours and it still works like new. So five stars unless I have a problem which I doubt.
