VGA, DVI, DP and a 1050ti

I have an older monitor that's DVI as well and it currently connected directly to my 1070 VIA DVI cable.

Use a VGA to DVI adapter.

DVI-D is sorta dated and is video only, DP is the new ultimate standard for high quality stuff (4K, 144Hz, video+audio, all those things). In your case there should be no difference performance wise. And you have to connect your monitor to your adapter, which you connect to your video card.

How about you retire that VGA monitor and buy a cheap Full HD TFT, they don't cost an arm and a leg anymore.

I suggest just getting a new cheap monitor. I had a VGA old monitor as well, when I upgraded my PC I used a DVI-VGA adapter at first, but the image quality was not great. It had some noise to it, and it was somewhat noticeable, so I just ditched the monitor, got a cheap one and just bought a DVI cable and it's been pretty great so far.

TL,DR: Just get a new monitor for that video card, bruh.

the 1050 should have a hdmi port, get a vga to hdmi adapter like this one and you're done (i'm using one for an old monitor like yours). you can use your old vga-vga cable.

My question is, should I get a dvi-d to vga one or a display port to vga?

Either will work, but DVI-D to VGA will probably be a dollar or two cheaper.

And does the motherboard have to support DP or do I connect the monitor straight to the graphics card?

Fasten that sucker right up to the graphics card.

You can totally connect your existing monitor to the new video card, as others here have suggested. But given how old the monitor is, and that it's VGA, you would get a huge improvement to picture quality from a new monitor.

You could go the cheap route and just pick up a cheap LCD panel. Or, given how long you seem to keep your monitors for, you could go the expensive route and pick up a great new gaming monitor with G-Sync. Eliminating visual tearing and frame-time spikes makes for a super-smooth gaming experience that feels like a revelation. ASUS make some of the best ones.

Or you could go with a cheaper FreeSync monitor paired with an RX 570/580, if that works out better. Again, ASUS makes some of the best ones.

It's going to be way more expensive, but you'll be much happier with it over the years to come.

I'm in the same position.
I have 2 VGA monitors, and for the gtx1050 I need 2 adapter. One HDMI to VGA, and an active DVI-D to VGA

A new monitor would be better. At any rate, DVI-D to VGA converters are usually expensive. I am surprised that your card does not have a HDMI port, but HDMI to VGA and DisplayPort to VGA converters are around the same price point and both work splendidly.

DVI D isn't compatible with VGA so you need one for a different port. But I recommend getting a cheap 1080p monitor instead.

I got 2 monitors that have DVI because my GPU has them... and now all the new GPU's have hdmi and dp only... so.... be careful not to look into the current state only but what the future brings too.

just get an old & used 1920*1080 off ebay. it doesn't need to be perfect, it just needs to work. now and for the next 12 to 24 months. recently i got two for me and the family for 25€ / 30€ per piece. one benq and one aoc, not brilliant but perfectly adequate. even in the same town so it was a two minutes car trip to get them.

if your monitor comes with vga only it's high time you throw that junk away. at this point all the money you spend on cables and adapters is totally wasted. just don't do it.
