Power delivery by itself could be a useful standard for ebike and power station charging (battery to battery charging too). 480w is most I've seen, but maybe USB is working on better, or 240w and more flexible/cheaper cables can work. HDMI providing 54v output would be great for most common battery system charging, and dual/triple BMSs for 2x and 3x ports/charging would be awesome.

If it's not usb-c it's banned in EU. Because we stopped there and we won't go forward.

Please don't make stuff up.

Other stuff isn't banned and the law already has allowances for emerging standards.

I think you could have a second connector in addition to a main USBC.

Honestly we need higher capacity for screen cables for PC. Both HDMI and display port are limiting performance because of their low, 40-80gbps, bandwidth. Their performance maxes out at 4k120hz with uncompressed HDR color. You can't use 8k screens or multiple 4k screens without lowering quality.

[–] ceiphas@lemmy.world 2 points 1 week ago (2 children)

Where I work, everyone has 2 4k screens. You can use two cables to connect them, you know...

And every one of them has either put their scaling up to 150% or simply set them to 2k, because you cannot read a damn thing on them.

More than 4k is a theoretical need for a veeeery small market

I disagree with the more than 4K being a theoretical need thing but, regardless, where I work, every desk has a pair of 4K monitors that connect to the user's laptop via a single USB-C cable. That cable also connects a keyboard, mouse, gigabit ethernet and, depending on the desk, 10Gb ethernet, multiple cameras and conference audio. The cable also charges the laptop, of course. At the moment that's mostly done using USB-C docking stations, but we've started to deploy monitors that are USB-C native and can be daisychained together.

Graphics cards only come with one HDMI port though. The LG OLED is popular for 4k screens because it ticks all the boxes and is much cheaper than equivalent gaming monitors, but that means it doesn't support dp.

And it means that you have to upgrade the graphics card just for the cable even if it is still relatively new. The point is that we shouldn't be held back by just a cable .

[–] rmuk@feddit.uk 4 points 1 week ago

Graphics cards come with as many ports as the manufacturer wants them to. My home PC's GPU has two HDMI and two MiniDisplayPort. Also, there are cheap lossless adapters that will convert between MiniDisplayPort, DisplayPort, HDMI, DVI, etc, etc.

Actually? I don't know much about that legislation. Does it really not have room built-in for tech improvements?
