Needs MOAR POWAH.
Zachary White
to power it
Hunter Lewis
Oh so it's not just a simple "wiring" adapter but in fact an active converter?
Fuck, who invented this retarded fucking DP?
Gabriel Ortiz
hdmi has royalties
displayport is royalty free
displayport wins
Luke Garcia
I'd blame HDMI for not being able to draw power through the GPU before I'd blame the DP
Andrew Long
pretty sure hdmi is able to provide power, ethernet, audio and video
James Hernandez
It doesn't technically need one, but I'm sure there would have to be some fancy hacks done to get the display host to supply power to the adapter via HDMI. USB power is simple to implement.
Luis Jackson
Active adaptors. So you can use freesync.
Samuel Stewart
(Also it's only a fraction of a watt.)
James Wright
Why does DP need power via USB to function then?
Nathan Cooper
>hdmi is able to provide power
It isn't, even the Chromecast dongle and the Intel Compute Stick thing need separate power via USB.
Grayson Foster
>$60
>even with $20 off it's $40
JUST
Samuel Roberts
HDMI ports deliver a minimum amount of power, but some devices are able to provide more than others, so if your device isn't providing enough you can use the USB to power it.
Brayden Kelly
use aliexpress, you can probably find for for 1$
Nicholas Ward
>It isn't
Yes it is.
hdmi.org
Benjamin Powell
>buy active HDMI to DP adapter
>sound plays on the PC internal speaker instead of the TV
WHY
Christopher Morris
The cheapest on ebay is $30
Aaron Baker
It literally is. You're just not considering two things:
1) all devices are not identical; some things require more power than others, and
2) the Chromecast is on the wrong end anyway since it's the host, not the client.
Ayden Wilson
Because the HDMI to DP DD only handles sound you'd need a second one for audio.
>Retard version, you only have the video conversion circuit.
Mason Morgan
>2) the Chromecast is on the wrong end anyway since it's the host, not the client.
Doesn't matter.
Samuel James
>tfw my thinkpad doesn't have hdmi
>bought DP to HDMI cable
>works on everything but an epson projector
>it's detected and all but there's no image
well fug
Jacob King
>not all devices are identical;
Fixed.
Some devices are identical.
Gavin Powell
He didn't say to use eBay, dumbass.
Hunter Jackson
No, strictly speaking no devices are identical.

Brandon Gomez
But the item description said it allows both video and audio to pass through amazon.co.uk
Did I goof up?
Isaac Reed
Display port almost fried my fucking PC, too many cheap knockoffs powering pin 20 when it should be not connected.
Camden Reed
Did you try different resolutions on your laptop? Also, forcing it with fn + projector key and setting git to duplicate should work
