Problems with 3rd monitor

I have spent a few hours trying to fix this and really couldn't.
Hopefully I can get some help here!

I have 3 monitors all connected to my PC, Windows 10.
Monitor 1: HDMI connected to HDMI on the PC
Monitor 2: HDMI connected to a displayport-adapter on the PC
Monitor 3: HDMI connected to a DVI-D or DVI adapter on the PC

The problem is with monitor 3.
It is showing all 3 monitors in the settings: System, Display.
Clicking Advanced display settings takes me to a tab showing all 3 ASUS VN247 monitors connected to my computer using Intel(R) HD Graphics 630.
Almost same settings are set on all monitors, the only thing is that monitor 2 has 59 Hz Refresh rate instead of 60 which monitor 1 and 3 have.

So, when connecting this monitor 3 to any other output on my pc it works totally fine but whenever I connect something to this DVI-D or DVI adapter then it only says no signal and then shows a black screen.

I've tried unplugging everything many times with many different cables.

Everything worked totally fine today but it was only today that I dragged all connected cables to my pc out to fix some cable management.

Is the problem with my computer or the adapter or would this be something else maybe?

Thanks,

Answer
why the adapter?

Is it DVI to another type DVI plug/port? HDMI to DVI or vice versa? You mention the possible villian in this setup, and then give almost no information about it.

DVI (Male) to HDMI (Female)

My computer only has one HDMI output, the other outputs are display port and DVI so that's why I need to connect an adapter as the monitor doesn't have DVI outputs.

So basically the computer has one DVI output which there I have and always used an adapter, DVI (male) leading to HDMI (female) which then leads to a connection to the monitor using a 3-5 meter HDMI cable.

Not supported according to Intel.

59 or 60. There are plenty of discussions about that so I feel we note it, move on.

The REAL problem is your setup is NOT SUPPORTED.
Read https://www.intel.com/content/www/us/en/support/articles/000025673/graphics-drivers.html

Move to a supported configuration then it might work. And yes you might have to disable Windows 10 Driver Update system then install the driver from Intel but you haven't set it up per Intel yet as far as I can read here.

VGA / DVI?

Not sure exactly which driver I would need to install but I installed the latest graphic drivers for the intel 7th generation, did not fix this problem.

Do I need to get a graphics card that has VGA or display port output for this to work?

Also, the (graphics/card) is built inside the motherboard if that's something to know.

As long as you have an unsupported setup.

I don't think it should work.

BUT I WANT TO ADD THIS NUGGET.

-> Microsoft on Windows 10 will silently replace your installed driver of choice. Only by disabling Windows 10's Driver Update (not to be confused with Windows Update and how is on the web) can you be sure your choice of driver stuck around.

Again, the setup you seem to show in all the posts do not get you to a supported configuration. I've seen folk battle this for years and some never get it working since... they don't go with a supported setup.

You could try switching HDMI cables between monitors,

,,,see if any change. There are several HDMI versions over time. There's also different versions of DVI. Unless it all matches up perfectly, there will be problems. Has this ever worked?

"DVI and HDMI compatibility

HDMI is a newer digital audio/video interface developed and promoted by the consumer electronics industry. DVI and HDMI have the same electrical specifications for their TMDS and VESA/DDC links. However HDMI and DVI differ in several key ways.

HDMI lacks VGA compatibility and does not include analog signals.
DVI is limited to the RGB color model while HDMI also supports YCbCr 4:4:4 and YCbCr 4:2:2 color spaces which are generally not used for computer graphics.
In addition to digital video, HDMI supports the transport of packets used for digital audio.
HDMI sources differentiate between legacy DVI displays and HDMI-capable displays by reading the display's EDID block.

To promote interoperability between DVI-D and HDMI devices, HDMI source components and displays support DVI-D signalling. For example, an HDMI display can be driven by a DVI-D source because HDMI and DVI-D both define an overlapping minimum set of supported resolutions and frame buffer formats.

Some DVI-D sources use non-standard extensions to output HDMI signals including audio (e.g. ATI 3000-series and NVIDIA GTX 200-series).[9] Some multimedia displays use a DVI to HDMI adapter to input the HDMI signal with audio. Exact capabilities vary by video card specifications.

In the reverse scenario, a DVI display that lacks optional support for HDCP might be unable to display protected content even though it is otherwise compatible with the HDMI source. Features specific to HDMI such as remote control, audio transport, xvYCC and deep color are not usable in devices that support only DVI signals. HDCP compatibility between source and destination devices is subject to manufacturer specifications for each device."

Did not fix

I tried switching them, does not fix the problem

HDMI cables have the same model

Also the HDMI cables do have the same model and there's been no change with what cables or so I'm using since last time it worked. (Yesterday)

Get the Intel drivers then

Maybe windows 10 sent out a driver update and it messed you up. Turn off Windows Driver Updates, they cause more problems seen in forum than people getting virus and trojans. Go to your computer manufacture site, get their drivers for the computer, install them.

Which intel drivers?

I downloaded an older intel driver graphic which I got from the asus website. (the motherboard I use)
I also tried downloading the latest driver for the intel graphics I have but that did not solve this problem. Could you send a link or something on what you think I should try and download/update?

I built this computer together with some help from two others also.

I tried looking around abit and I'm not toally sure what to do, I did disable the automatic windows driver update tho

Did not work.

I Installed all the drivers there, not the BIOS ones and this did not solve the problem.

done all you can

I'd suspect the adapter as having become defective.

Will test as soon as possible.

I'm trying to get a way to test this adapter by getting a new/another monitor so that I can connect the computer dvi output to the new monitor

a thing I wanna add is that I've recently, maybe even when I got this problem with my montior. It is that my computer starts making a weird noise with the fans or the power supply maybe, not sure if that is something tho but I'm looking to hopefully test and connect a DVI cable to the computer's DVI output.
