I wouldn’t count on it. There will always be a need to connect external peripherals, and they’ll just continue to update the spec to expand its capabilities.
HDMI 2.1 supports 4K120 and 8K60, I expect that alone will be sufficient into the 2030s.
It is dying. I've got a mess of monitors that are VGA/DVI, and the video cards don't always have that output anymore. Some do... but watching them fade. VGA maxes out at 1920x1200 or so before you need to make the jump to DVI. Think dual link DVI starts at 2560x1440.
If you know of a 3080 that has DVI, I'm interested.
it's dying off as a source, but my guess is it will remain as an input for a long time. the TV I bought this year still has component video inputs. when's the last time you bought a piece of equipment that only outputs analog video?
There are no options that push pixel clocks that native RAMDACs can. The Delock 26297 (which needs to be imported from Germany) can hit about 250 MHz, which is enough for most uses. Unfortunately, the connector is total rubbish and causes serious signal integrity issues. I have two and one of them can barely hit 150 MHz.
There is a USB-C option which can supposedly hit 300 MHz.
RAMDACs hit 400 MHz. It’s a real shame they’re not in new cards. Hence my point: VGA is dead because it isn’t in new hardware.
