The HDMI Forum, responsible for the HDMI specification, continues to stonewall open source. Valve’s Steam Machine theoretically supports HDMI 2.1, but the mini-PC is software-limited to HDMI 2.0. As a result, more than 60 frames per second at 4K resolution are only possible with limitations.
What about shipping an adaptor? DP to HDMI for the transition?
Phone companies succeeded in killing 3.5mm audio port with that strategy. So why not, for once, use it for a good cause?
Can dp even translate to HDMI with a “dumb” adapter?
DP can do HDMI natively.
HDMI needs an active adapter to support DP.
Yes, DP converts to HDMI natively. But because HDMI has so much proprietary BS built in, going from HDMI to DP requires an active adapter which strips out the proprietary BS.
yes, i have a dp to hdmi 2.1 cable that cost like 35€. it works fine except each time i get up from my chair the screen flashes white. and no VRR.
Wha… how? What?
ESD. the air is extremely dry here
Put a ferrite core (or ferrite bead) around your cable to lessen the impact ESD has on your video output.
good tip, I’ll try that!
Whoa
There are a lot of passive adapters out there that seem like black magic at first.
Obviously has drawbacks, but you can also do displayport/hdmi to VGA passively.
That is not passive, they have to “translate”.
Oh, you may have got me.
By passive, I was trying to say that no external power/additional connection/etc is required. But, the port is technically powered and that is enough to make it not passive.
I have a 25ft HDMI cable that works fine for everything except sometimes when I open a new tab in Firefox, the screen temporarily goes blank/no-signal for a couple seconds. Also sometimes when the dryer turns on.
my friend has had this issue for years, when he turns on a fan his monitor turns off for a second
Yes.
I have a secondary monitor running on a unpowered, dumb (and cheap), DP to HDMI driver right now
Technically no, it has to specifically have Dual-Mode support (DP++). In practice most of them do, at least in the consumer space.
If it doesn’t then you need an active adapter.
Can’t be a passive adapter or else that would mean DisplayPort and HDMI have to protocol compatible. If they were then we wouldn’t have this issue.Apparently I was wrong.Nope. DisplayPort can adapt to HDMI or DVI passively. It won’t support the proprietary bullshit like HDCP, but it will be able to display video just fine. Pin 13 on DP is specifically used to detect adapters, so the output device can automatically change to using an HDMI protocol if it detects an HDMI adapter. This technically requires a dual-mode DP port to automatically adapt, but the vast majority of DP connectors produced in the past several years are dual-mode.
But going the other direction (HDMI to DP) requires an active adapter, to strip out all of the proprietary HDMI-only bullshit.

Here’s an already filled in Google search for you.
Oh wow thanks! Alright everyone. We can all get off lemmy now. Turns out we can just look everything up online. No need to waste time talking to each other. Ugh!
Or you can simply look up the answer to a super basic question in the same amount of time it takes to ask it in a forum so that you’re contributing to the conversation, rather than lazily putting it on other people to answer.
You can’t look up everything online, but you can look up basic information fundamental to the conversation you’re in.
Or choosing to ask a question means they actually want to hear what other people have to say and not whatever AI slop the major search engines have become

friends don’t let friends use google.
where’s the Google in this search?
