A year ago, I had the same desire, but in to a monitor.
I couldn't find one.
Apparently, the connectors are manufactured by fairly large factories due to the volume of technology involved. They are not interested in small batches.

You can swap DVI for HDMI, but it's not easy-peasy. The easiest thing to do is to simply use an adapter or cable with one on one side and the other on the other.

Yeah, that's why I figured there might be examples from say the gtx8800/980 era.

There's usually old stock if they exist in the first place. Agp and slot 1 are still around

Seems like most DVI connectors are "through hole" while most HDMI connectors have surface mount data pins.

I mean that they didn't exist at all.
At a serious level of r&d, it's not a simple thing.
There are all kinds of wave issues, such as attenuation and all sorts of impedance matching. With zero demand, development is unprofitable.

This may also be related to patent restrictions.
For such a connector, you will have to pay both DVI and HDMI fees, i.e. twice as much.

HDMI is the only one with license fees. DVI and DisplayPort do not have license fees

Hard to tell.
Looking for better pics.

At that time, attempts were already being made to install HDMI on DVI transceivers.
The connector there is a standard HDMI connector.
Just double tracing on PCB

Sapphire isn't galaxy?

My solution to this issue has always been a cable with HDMI on one end and DVI on the other. These still exist and work fine.

Even if easily swappable connector modules did exist, I don't understand the advantage/use case for altering old hardware in such a way. That being said, there does not need to be a reason for wanting to do this, but the absence (or scarcity) of potential use cases (for most people/companies) would have limited the chances of anyone deeming there might be a market for such a module and manufacturing some, let alone in any significant numbers .

EDIT: It's likely much cheaper to design and manufacture a PCB that can accept either DVI or HDMI connectors (or various combinations)., as @shevalier showed in that Sapphire example. As for having an existing DVI design and wanting to convert it HDMI, why would a manufacturer want to bother bother with the trouble and cost when bundling a cheap passive adapter cost a few pennies rather than just implement an HDMI or flexible HDMI and DVI PCB for their next product ? My point is that, even when such a module would have been most relevant, there was very likely little chance of it having been produced. It would probably have been viewed as a "solution in search of a problem", IMHO.

EDIT2 : The modern hobbyist solution these days would be designing and low volume manufacturing an interposer PCB that fits in the DVI solder holes and and had a HDMI connector soldered to it. As others have mentioned, one would need to be careful to take into account potential signal issues due to the high frequencies involved.

Before Sapphire became an AIB partner of AMD, it was better known as a PС-partner.
So definitely not.

Maybe adapting something like this could work.

I use it myself when necessary, but sometimes I want something unusual.
HDMI is good because it's easy to pull out.
If you don't have a dedicated space for your hobby, it's a little more enjoyable to assemble a system with HDMI.

When I see such technical solutions at 165 MHz, my eye starts to twitch. 😀

How about creating a custom HDMI adapter on PCB to replace DVI-port?

I found some HDMI boards on AliExpress but I'm not sure if the pins match with DVI.

I believe it is possible to make a board that does not protrude HDMI beyond I/O bracket.
HDMI-port needs to be raised to a height so as not to short SMDs around it.

I'm afraid that such a board with this level of development will have very strange effects.
It works with a 1m cable, doesn't work with a 1.5m cable, and works again with a 1.8m cable.

If there are DVI and HDMI footprints, this is very easy to do in CAD.
Create a group of connections and set their wave impedance. Specify that length matching applies to them.

Click ‘automatic routing’.
Check that the earth plane of the differential pairs of conductors is physically located exactly beneath the conductors themselves.
Adjust the power ground plane.
Export the Gerber to the https://jlcpcb.com/.
Go drink a beer, because it's Friday.

I really can't see the point in this, there's going to be a cable attached to the port either way so what does it matter if it's extended by ~8cm with an adapter cord?

no, if you look carefully you will see two distinctly different THT footprints

the HDMI THT connector has an extremely short backset

EDIT: or, possibly they actually routed three footprints to the same spot and the HDMI is indeed SMT while the ultra short backset THT footprint is for one of those low profile VGAs

honestly this, whole topic is pretty damn silly

not to mention you can buy premade cables with the correct connectors already attached if you're antidongle

That's a fair point, that you previously brought up and that I pointed out in another post. That being said, such a gadget may not be meant to actually work at 165MHz, considering what it is being marketed for. Assuming it would not work reliably or at all at 165MHz (or even significantly lower frequencies), shoehorning one into a card would make it less functional. If OP doesn't care about anything except very low resolutions AND does not care about the risk of making a card less functional, it's their time and money if they want to try, after all.
