I think it’s aimed at TVs in general, not computer monitors. Many people mount their TVs to the wall, and having a single cable to run hidden in the wall would be awesome.
I wonder what the use case is for 480W though. Gigantic 80" screens generally draw something like 120W. If you’re going bigger than that, I would think the mounting/installation would require enough hardware and labor that running out a normal outlet/receptacle would be trivial.
Headroom and safety factor. Current screens may draw 120w, but future screens may draw more, and it is much better to be drawing well under the max rated power.
Even in that scenario it will complicate the setup. Now your Roku will also have to power your TV? No, any sane setup will have a separate power cable for the TV.
I don’t think you’d ever have a peripheral power the tv. The use case I’m envisioning is power and data going to the panel via this single connector from a base box that handles AC conversion, as well as input (from Roku etc) and output (to soundbar etc.). Basically standardizing what some displays are already doing with proprietary connectors.
Passing power through doesn’t have to put noticeable load on the GPU. The main problem I see there is getting even more power to the GPU - Nvidia’s top cards are already at the melting point for their power connector.
That’s what I meant. Compared to the power the GPU is actually using, transmission losses for a pass-through should be negligible. If you have a good way to get it to the card in the first place.
The popular use for power delivery through a display cable is charging a laptop from your monitor; it’s already very common with Thunderbolt or USB-4 monitors. But 480W seems a bit overkill for that.
That already kinda allow this and the actual load is pretty small
Even a big 30 in display is maybe 20 watts
Well, power delivery goes several times that. Laptops are another very useful case for it. It’s nice to be able to just have a single display port and power connector
This must be for commercial displays where it is beneficial for installation to have power and data over a single cable.
I can’t think why I would want power delivery to my PC monitor over the display cable. It would just put extra thermal load on the GPU.

Sound for an 80" screen? Not for home systems.
Projector
In HDR mode they can draw a lot more than that for short peaks
My 50" 1080p LCD draws over 200w…

In wall power cables need to be rated for it to prevent fire risks. This will need to have thick insulation or be made of a fire resistant material.

I specifically said thermal load. Power delivery always causes heat dissipation due to I2R losses.

Nah, it’s for powering the 1000w RTX 6090.

~~Why is that better than usb-c? ~~
Wait… Power the other way. Whoops, I get it.

You can do this to an extent, today
