Over the years, we’ve seen a good number of interfaces used for computer monitors, TVs, LCD panels and other all-things-display purposes. We’ve lived through VGA and the large variety o…
Not sure pricing now but historically HDMI was a lot cheaper so if you do not need it why pay for it. Typically it was on enterprise devices not consumer. Heck I am still using DVI on my workstation and KVM switch . Works fine and cheaper.
I’m using an HDMI KVM and using several adapters because one of my two monitors only supports DVI and the 3080 only has a single HDMI slot and 3 DP, so the image quality must be trash lmao. In the impossible future I might update the screens, the KVM, and then but more adapters because the usbc adapter of the laptop has no DP connections, and dp->hdmi adapters are cheaper than a usbc extension with multiple connectors, those are expensive.
Totally not looking forward to spending 500+ on two new monitors, the KVM and all the cables, while having to think that to do with the old cables so my partner doesn’t kill me :_)
DVI and HDMI are actually the same video signal. Which is why adapters are so cheap.
DP can carry an HDMI encoded signal (and thus a DVI signal), which is why DP->HDMI and DP->DVI adapters are so cheap. It’s called DP Dual Mode or Multi Mode or something like that.
I haven’t encountered a device that outputs DisplayPort that cannot output the Dual Mode HDMI encoded signal as well.
HDMI/DVI->DP is an active conversion - ie it is re-encoding it. Which is why the converters are significantly more expensive.
However, it’s all digital. If the signal quality degrades, it will be very obvious because it stops working (sparkles on a black screen, lines, flashes, all sorts).
KVM switchs in particular are expensive and not all work well so it can be hit or miss. I will update mine at some point and move past DVI. To what who knows.
