Computer not connecting to monitor with dvi-D to vga conversion

[greenolive]

When i got my graphics card i put it in plugged my video cable in turned on my computer and downloaded the drivers everything worked fine. Then I try turn it on again and my monitor says no signal.My monitor only has VGA input and my graphics card only has DL-dvi-d , hdmi and display port output. so i got a dvi-d to VGA adapter.
-this is what iv tried:
-moved Ram into different slots
-moved graphics card into different PciE slot
-i borrowed a different monitor for testing with a hdmi input and tried with an hdmi cable into my graphics card that worked fine
-then i tried with my dvi-d to VGA adapter into that same monitor it worked the first time but the following times just said no connection

these are my specs:
gtx 1050ti 4gb
msi Z370-A pro
500w psu
LG 20M38A monitor
Dvi-D to VGA adapter

possible problems?
the fact that it worked first both time makes me think it could be software
possibly faulty adapter but why would it work both times on the first try

I know little about computer these are just geusses using logic,

DVI-D stands for DVI-Digital and its only if you go for DVI-D to HDMI, you need either DVI-I cable or DVI-A cable (I-integrated both signals, digital and analog, A only analog) in short, buy DVI-I

The GTX1050ti only outputs a digital video signal, while VGA is an old analog video technology. You need an "active" DVI-D to VGA converter/adapter. I'm almost sure that the adapter you're using is not active, i.e. it doesn't convert the digital video signal to a VGA analog video signal. Try something like this: https://www.amazon.com/CableDeconn-Active-FeMale-Adapter-Converter/dp/B01DW2BJWU/ref=sr_1_3?s=electronics&ie=UTF8&qid=1523042629&sr=1-3&keywords=active+dvi-d+to+vga+adapter

Yes you're right.

it looks to me that mine is active, it also doesn't make sense that it would work the first time if it wasn't active.
this is the one i have http://www.ugreen.com.cn/product-808-en.html

Show us a link or photo & we'll tell you if its active or not.

You see the little micro-USB jack on the box that holds the VGA part? It needs to be connected to a USB-A jack as a source of +5v power. "Active" means it needs power to do its job and many DVI ports are not up to the task of supplying enough, because the spec for DVI only requires enough power to read the EDID of the monitor.

hey thanks so much could you please explain as how i can do this, like what i need to get where, i need to plug it in ect?

could i just use something like this https://matrixwarehouse.co.za/303-usb-to-micro-usb-cable.html and plug it in a usb port and then in the adapter

Or just get a new monitor that's not an old piece of junk.
VGA isn't coming back, and DVI is also dying off.
Displayport monitors are the future.

dont have the funds

Craigslist is your friend. Often used monitors can be found cheaply there.

Yes that is the type of cable needed, exactly the same kind normally used to charge a phone. Sounds like the converter just needs a little more power if it can draw enough from your DVI port to run @ 800x600 before the video driver gets installed, but not enough to run at full resolution.

That means even those 1.0A rated cables from the dollar-store should work. Is there an equivalent sort of place in South Africa?

im sure i can find one i just dont understand why it worked the first time, it was running on 1600 by 900 and i played games like fortnite on high graphics for a couple hours, can you explain this? i just dont want buy something and it doesnt help.

 

[Scottray]

My guess is that the dvi to vga adapter was drawing just enough power to work once. It's right at the edge to function. Just get a usb to micro-usb cable to power the adapter.

Thanks so much to everyone that helped! Everything working now.
