Comment on HDMI 2.2 will require new “Ultra96” cables, whenever we have 8K TVs and content
sxan@midwest.social 2 weeks agoIs DVI completely out of the picture? I hate the connector, but I’ve had a lot of issues with DP, mainly around Linux support and multi-monitor setups.
I was kinda hoping USB-C/4/Thunderbolt would step into this space and normalize chaining and small connectors, but all of those monitors are stupidly expensive.
DVI isn’t capable of the bandwidth needed for higher resolutions. Even dual link maxes at about 8 Gbps and 2560x1600 @ 60Hz. This new HDMI spec is 96 Gbps for reference.
Ironically though HDMI is pin compatible with DVI and you could output HDMI to a DVI monitor with just a simple HDMI to DVI cable, or vice versa. I know a lot of people who like DP bit in order to convert you need active circuitry and that can impact quality if you don’t have native DP on both ends.
I was going to ask, but I just looked it up: it looks as if USB-4 has enough bandwidth to drive dual 4k monitors at 120Hz (and docks exist that support this).
USB4 uses something called DP-Alt where it’s actually DisplayPort over USB exactly what you’re looking for. I have a portable USB-C monitor that runs powered and video over a single connection
I also find USB to be limiting when it comes to range. I can go about 50 feet with a nice thick HDMI with copper wiring, but any further than 20 feet on USB necessitates fiber optics. Not an issue for everyone, but something I have been running into.
That’s one I hadn’t encountered. At those distances I start contemplating wireless solutions.
Got myself a nice outdoor POE camera, a bunch of appropriate CAT and power adapter… and then realized that since the previous owners had put in a sheet-rock ceiling (not complaining; drop ceilings make me fell like I’m living in a warehouse), I had no easy way to run the ethernet all the way crosswise across the house from where the switch was to where I wanted the camera. I’d been thinking since the utility room wasn’t finished I’d figure a way to thread it with a flashlight and a “step 3: ???”. The moral is that running long wires is not my favorite thing.

The only problems I’ve had with DP are when I have to put it through an adapter to turn it into HDMI for a display that didn’t have DP input.
Video over USB-C just ends up being Display Port, doesn’t it? I guess it depends on the subtype of USB.
