Re: Soldering a DVI connector on a VGA-only motherboard.
I have finally ordered the parts. I ordered from aliexpress and I don't know when they will be here, but the moment they arrive I will post back, maybe just to bump the thread so that if anyone else is following this thread will be notified. I hope to mark the thread as solved. Thank you all.

Re: Soldering a DVI connector on a VGA-only motherboard.
You are right. Also, I have found that it needs 2x transistors, caps and resistors galore, a ferrite. I am ordering the parts together with a DVI connector. Thank you all for the heads-up. I will post back when I finish. It's going to take a while for some personal reasons.

Re: Soldering a DVI connector on a VGA-only motherboard.
Thank you for the reply.
So I have one thing that I haven't thought about: make sure ground is available at the socket.
I will post back results in a few days.
If it doesn't show anything in the BIOS POST, I will go deeper into the schematics of the DVI model of the board and see what parts I have to order.
Cheers!...Leave a comment:

Re: Soldering a DVI connector on a VGA-only motherboard.
I think you're right, the gigabyte board supported only digital dvi, but I got audio working oob in windows through that DVI connector. I don't have that board anymore anyway. What would happen if I solder the wires on the board, on the digital DVI rails? I might do it anyway, so please, I just need some insights, posting back results. Let's have some fun with my board....Leave a comment:

Re: Soldering a DVI connector on a VGA-only motherboard.
It does indeed support audio. I had a Gigabyte H81M-S2PV, which had VGA and DVI. DVI was both digital and analog (different rails, I know) and the TV that was connected to, had also audio if I used a DVI/HDMI adapter. So from this I understand that digital dvi signals are same as HDMI, at least on the TV/monitor side. On the motherboard side is a different output, with it's own framebuffer, pipe and stuff....Leave a comment:

Re: Soldering a DVI connector on a VGA-only motherboard.
Thanks for the reply. I really want an open minded approach, meaning that even though not having enough experience, I wish to bypass the dvi connector and just use some of the contacts, for the digital signal. No audio needed, as I use the green jack. Again... I know it's raw or reckless, or you name it! So if solder the wires on the contacts before the SMDs, would I get image on the monitor? Imagine a digital DVI monitor with the cable soldered on the PC motherboard. Finding the right contacts is not a problem. Bypassing...Last edited by freeman0711; 10-01-2020, 05:48 AM.Leave a comment:

Re: Soldering a DVI connector on a VGA-only motherboard.
I have a VGA connector only, so I am interested in the digital part of the DVI. There are no smd parts fitted for the DVI connector and I do understand that they should be there if I want to use it. What is the importance of them and could it work without them? was the main question. I could bridge the contacts with solder. Actually I am not even going to use a DVI connector, I only need the rails. I have the pinouts for the DVI, board schematics and boardview for all 3 ASRock H81M-*G4 motherboards. Again: how important are...Leave a comment:

Soldering a DVI connector on a VGA-only motherboard.
Hello. How important are the SMDs right before the DVI connector? Can it work without them, given that, if necessary, I could just solder the contacts for continuity. I know it's raw and reckless, but can it output DVI signals without them? I want to add a DVI port to a VGA only motherboard. ASRock H81M-VG4 and using boardview for H81M-DG4. Same H81M-*G4 board. I have option in BIOS for IGP multi monitor and my pockets have holes.
Any insights appreciated. -

Hello and good to be here! My name is Alexandru, 32 y/o romanian living in Spain. I never learned electronics in school or courses, I was fascinated by the way the electrons can be manipulated and quickly got absorbed in electronics. I still have a lot of gaps in info, but I like to play with everything I get. I used to open devices just to see why they work (some here might know that feeling). I have started IT with a non-working i386 computer and thanks to Dodi, an old man that had electronic stuff all over his house, I made...Leave a comment:
