I posted a while ago about criteria to choose a new monitor, and although the connectivity aspect was listed, I've delved a bit deeper into it now seeing I need to replace a monitor myself.
What I've noted is more DisplayPort (DP) connectors on new video cards, as well as the fact that DisplayPort is giving better bandwidth throughput. Both HDMI and DP will handle sound (although speakers on monitors are usually awful). A problem seems to be that monitors are lagging behind a bit (if I look at what is locally available to me in South Africa), with all carrying HDMI connectivity but a lot fewer having DP, and I also note that for both types, the versions are a lot older than the video cards themselves. Also interesting that I see far more monitors with AMD FreeSync certification, and a lot fewer with NVidia's G-Sync, and a few have both.
It's good to see, even budget priced gaming monitors, are standardising on 144Hz upwards, with 1ms response times. But based on the DP evolvement and AMD FreeSync, it is interesting to see how the market seems to be shifting a bit now.
However, the product description on most online retailer sites are just terrible. They are especially bad with omissions around all the port connectivity options and the sync options. I've had to do a lot of double-checking because I had discarded options based purely on the retailers' sites, which were incorrect.

We look at bandwidth, resolution, refresh rate and more to see the differences between DisplayPort and HDMI connections.
