What I always liked about HDMI is that it's basically backwards compatible all the way to DVI, just using passive adapters. I think that's the reason why HDMI dominates on laptops, where you're expected to move around and use projectors, which could then be very old and only have DVI inputs, and it "just works" with a plain old adapter. You could even go the other way round from a DVI output to a modern HDMI projector using the very same adapter, but I think laptops pretty much skipped DVI and went from VGA to HDMI. So in practice it doesn't really matter, especially with DP++ being supported by almost every device, which effectively gives you HDMI output using an almost passive adapter.
But still, I like it. :-)
- spintin 3y agoI recently discovered you cannot pass 75Hz over DVI -> HDMI -> DVI! For some reason the bandwidth is too low? So for 60Hz there is interop. but for 75Hz you need a thick DVI cable.

- oynqr 3y agoHDMI can only carry single link DVI as far as I recall.
- ghusbands 3y agoHDMI currently supports up to 144Hz. Even HDMI 1.4 (2009) could reach 120Hz. However, compatibility is hit and miss in general. You may have had luck replacing one or more cables or adapters, but switching to displayport is likely to get the best results, anyway.

- ffsm8 3y agoHDMI supports >200hz if you've got compatible hardware (HDMI 2.1). It's admittedly hard to get this hardware unless you're willing to pay for the top of the line versions, but it does exist. Budget hardware usually works better with display port however, that's true
