Post memes here.
A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.

Laittakaa meemejä tänne.
- Odota ainakin 2 kuukautta ennen meemin postaamista uudelleen

Same as VGA, shit just works, don’t need to worry about drivers or OS. So if your server shits the bed, you don’t need to worry about these things not working so you can can figure what went wrong.
Ok but Vega is still standard for servers, because you don't have to use proprietary bullshit like HDMI.
But just use DisplayPort instead.
Why? Nobody needs high definition from a server. Vega is literally unbreakable, super reliable and cost efficient. Display port would be a absolute waste just like HDMI. Same with most hardware applications that don't need high definition displays. The server ports are literally only used to set up the server.
This isn't just a royalties issue, its a issue of necessity.
IDK man, it would be great if my crash cart or KVM only needed one cable. I can’t wait for USB-C on servers to be everywhere
USB-C on servers is a good thing. But you seriously don't need a HD capable port on a server.
There is really no reason not too though. Displayport also takes up less space that would be used for cooling or whatever.
The only reason other than compatibility is probably that the screws are nice to have if you hook it up to something permanently like a KVM. Displayport have latches but imo they suck and I usually buy cables without them.
VGA is flaky and prone to issues. It doesn't have a way of reliability relaying information such as display metadata.
Everything in the world is hdmi or DisplayPort. VGA is essentially now a specialty connector used only in data centers.
HDMI has their fees, but DisplayPort doesn’t. Plus at this point implementing analog to digital converters is probably more expensive than just putting DP on it.
And no DRM bullshit like HDCP getting in the way.
I don’t know what server you’re running, but I have never had any issues with USB keyboards. They just work, including in the firmware. No drivers needed. Besides, a proper server motherboard will have IPMI so you can just remote into it.
I've had KVMs that don't like the 'fancier' USB keyboards with NKRO. It would work, but it wouldn't listen for its own 'switch to different console' hotkeys. Reconfiguring the keyboard to run in 6KRO-only mode addressed it, but not every keyboard can be configured that way.
In a server environment it's perfect. Have multiple baremetal servers in the rack?
No problem, all you need is a PS/2 + VGA KVM and you can control them easily without fiddling. No protocol handshake, no HDCP in the way.
PS/2?
I'm not completely sure but I'm pretty sure that at least the majority of our servers only have USB and no PS/2 port. And while our servers aren't very old some of them still have a few years on them.
Enjoy your 720p analog signal.
Display port is where it is at
For most workflows, especially text, 720p is more than enough.
That said, DisplayPort >>>>> HDMI
Absolutely. There are applications that just don't need HD.
Of course it is, but I’m just talking about why these things survive
You've just gotta dig out the mouse/keyboard combo that came with the Packard Bell you bought in 1996 from some dusty box in the attic / storage room at work
