The HDMI to VGA adapter would have to be 'active' to work..... but if you're running DVI-VGA, it may not be.

Older, 'basic' adapters to go from DVI to VGA required DVI-I, which carried both a digital AND analog signals.

As of the 10 series, you have DVI-D (digital only) so, similarly, you need to run DVI-VGA via an 'active' adapter.

The monitor is VGA only.

No, a 1050TI will not *natively* support DVI-VGA using the basic adapters. You'd need an "active" DVI-D to VGA adapter.

This one strikes me as pretty cheap, but does state "active":
https://www.amazon.co.uk/Adapter-GANA-Converter-Supporting-displays/dp/B06XFR74K2/ref=sr_1_1?ie=UTF8&qid=1518106768&sr=8-1&keywords=active+dvi-d+to+vga

Realistically though, if you already have an "active" HDMI to VGA (which you would need for any HDMI out to 'work' with VGA), why bother with DVI?

Yep, that's what Barty is talking about. It is NOT active adapter, so will not work with this GPU.

So you're running an active hdmi to vga adapter from the card, then running a vga to dvi adapter ,then a dvi to dvi cable to the monitor.

Id expect that to work in all honesty , however id ask why would you need to do that ??

The dvi input on the monitor may only take a digital signal , you are feeding it with a straight analog signal.

That may be the issue here.

The DVI adapter you have is for DVI-I to VGA.

Your card does not have DVI-I, it's only DVI-D (so no analog signal, which VGA is/needs). You'd need an 'active' adapter, as I linked above.

What are you trying to achieve? A secondary monitor? Or just replacing your HDMI-VGA connection?
If you're not trying to get a secondary monitor up and running, I see absolutely no benefit in switching from HDMI-VGA to DVI-VGA.

OK, Barty he wouldn't even be able to plug in the adapter if the video card only did digital DVI out. The connector for DVI (Digital only) and DVI (analog + digital) are physically different (PINS are different). The fact that he can plug in the adapter means the video card's DVI port does DVI (digital + analog).

This is assuming he didn't bend the pins on the adapter to plug it in.

But, you were using HDMI-VGA on your prior card (I assume, since you have the adapter already)?

What resolution are you forcing on that monitor?

Honestly, rather than trying to figure out adapters etc, it may be time to upgrade your monitor.
From what I can find on your monitor (link to HP's site above) it's a 19" 1280 x 1024 VGA only monitor.

I can't think of any viable reason to pair a 1050TI with that resolution.

A "decent" HDMI ~23" monitor shouldn't set you back much more than 100 $/GBP/EUR, especially if you're prepared to look to the used market.

Going to be a much more satisfying 'upgrade' than your games being a bit lighter....

You're assuming he can successfully plug it in.

Take a look at any 1050TI with a DVI port.

DVI-D only.

https://www.techpowerup.com/222326/nvidia-geforce-gtx-1080-does-away-with-d-sub-vga-support

have done away with support for the legacy D-Sub (VGA) analog connector, with its latest GeForce GTX 1080 graphics card. The card's DVI connector does not have wiring for analog signals. Retail cards won't include DVI to D-Sub dongles, even aftermarket dongles won't work. What you get instead on the card, are one dual-link DVI-D, an HDMI 2.0b, and three DisplayPort 1.4 connectors.
Click to expand...

Now that speaks to the 1080 specifically, but it's true of the entire 10 series lineup.

I know. I'm assuming since he's saying he's getting a black screen... I'm assuming people know A LITTLE about plugging in stuff first before saying the screen is black. :D

I'd hope so too, but the fact of the matter is no 10 series card supports DVI-I.

Any DVI connector on those cards is DVI-D (as shown above), so when dealing with the facts:
1. no DVI-I on the card itself


2. that's a DVI-I to VGA adapter he's holding

So,
If it looks like a duck, swims like a duck, and quacks like a duck.......


Now, if it's *not* a 1050TI (ie a 900 series/700 series etc), that's a different story.

They actually make passive DVI-D to VGA adapters that look just like the passive DVI-I to VGA adapters. They don't work, but they are out there.
https://www.amazon.com/Evermarket-Female-Monitor-Adapter-Converter/dp/B01HV20TBO

DVI-I -Digital and Analog
DVI-D - Digital
DVI-A - Analog
VGA- Analog

All the 10xx series Nvidia cards no longer have ramdacs so they no longer support analog signals so all DVI ports are DVI-D.

I don't understand the second picture ??

That's the way you had it setup & working originly ??

Because that looks like an active adapter to me
Barty is right though , those old dvi to vga are just analog passthrough adapters & modern cards do not give out analog signals.

Your vga cable looka like it's held together by pieces of black insulating tape to me , that may be your issue with the signal quality loss.

The 2nd picture is the active HDMI to VGA adapter that is working. The 1st and 3rd are of a passive dvi to vga adapter that is not working(because it's passive).
