DP to VGA?

Sorry if this is the wrong forum. This question is for a mix of video cards and monitors.

So I just got my 1070 in and found out that the DVI port on it is DVI-D and it is not compatible with DVI-I. I had been using a DVI-I to VGA converter to drive my VGA monitor. The card has a bunch of DP ports though. Can I use a DP to VGA converter? I know they exist, but from doing some searching, I've seen some threads that said that people were having trouble getting them to work.

You can always order one off of amazon or such and if it does not work return it for free in many places if it does not work as advertised.

I strongly suggest you go out and get a halfway modern monitor with at least dvi or preferably dp as relying on vga this day and age is not something you should be doing and even more so if you are willing to shell out that kind of money for a top end video card.

Why oh why do you have a 1070 with a vga monitor? Get yourself a new monitor!

You'll end up paying ~$30 for an adapter since the cards only have digital signals so you need an active adapter

A DP to VGA adapter should cost you like $5, HDMI to vga tend to cost more for some reason.

Cheapest I've found is $9. But I was wondering about that active part.

Anyway, the 1070 is for driving my Vive. 7850 was great otherwise. Don't really have a need for a new monitor so just wanted an adapter.

Isnt a 1070 overkill for driving a VGA-level bandwidth display?

Ahh a Vive well that makes more sense :)

Can you keep the 7850 in the monitor? Do you plan on doing gaming on it as well? What about on board video -> monitor?

I think you will need an active cable because the dvi->vga cables otherwise need dvi-i like you mentioned, as it has the analog signal already, while most active cables will do the digital->analog conversion.

Yea, I'll be gaming on the monitor too. I don't think a 7850 can but used in conjunction with the 1070 though.

Maybe if the display and card is poorly done. But back when analogue signals were the norm, Matrox for instance, had really good outputs.

The Matrox Millennium G550 had a 360MHz RAMDAC which gave up to 2048 x 1536 (32 bpp @ 85 Hz), and being programmable I would imagine that it would have been capable of 1920*1080 @ around 130Hz.
Paired with a high-end 21" CRT such a res and refresh could challenge any GPU.
Of course, highly unlikely that anything but the absolute best DP<>VGA adapter would be to handled that kind of bandwidth, and I also recall that in those dim and distant days, those with big pockets for top-of-the-range CRTs tended to use BNC cables.
But anyway, the point I wanted to make is that the automatic 'old=bad' does not necessarily apply as what killed CRTs was their bulk, heat output and cost to manufacture, not their image quality or the potential to drive them at crazy refresh rates.
