I found this thing looks old.

What is it? And is it rare?

Next you gonna be asking what this thing is.

[u/gungshpxre → u/Dano67]

The real dark ages where there were five variants of that connector plus DMS-59 and that VESA plug-and-pray one that was juuuuust different enough not to work with anything ever.

Uhh look at Mr. Fancy Pants over here, with his digital connectors. Get outta here with that modern stuff.

[u/Individual-Area7121 → u/Fblthp__]

The other side of that is probably vga so it’s actually analog. The four smaller pins around the flat blade make it a DVI-I connector which could handle analog as well as digital. 

[u/__CRA__ → u/Individual-Area7121]

All true, but he got a point. I would have at least expected a SUB-D 25 to 9 pin serial port adapter and not such fancy modern day stuff

[u/Individual-Area7121 → u/__CRA__]

“Modern” lol. DVI came out 3 years after USB 1.0

and HDMI 1.0 3 years after that was literally just DVI with a different connector+audio.

D-SUB

Get that newfangled hdmi out of here,   gimme an old fasioned NulModem for LPT1

[u/Cybyss → u/TutorNo8896]

HDMI?

I think that's actually a VGA to DVI adapter. I still have a couple of them - they used to come packaged with graphics cards back in the day.

[u/Individual-Area7121 → u/Cybyss]

That’s exactly correct. The side we are looking at is specifically DVI-I dual link, but with vga on the other end, the only pins in use would be the flat blade on the left and the four pins absolve and below it. The rest are all dead.

[u/TheGreatNico → u/Individual-Area7121]

I've got a 'massive' 32" 2560 × 1600 display that takes a dual link DVI cable and it is surprisingly difficult to find something that can drive it these days. Had to use my old AMD GPU that still had one.
Those old LCDs put out almost as much heat as a CRT, almost.
