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.
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.
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.
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.
For most workflows, especially text, 720p is more than enough.
That said, DisplayPort >>>>> HDMI
