Now this is a weird problem that I cannot get much info on.
I have been using an active Displayport to HDMI adapter to use TV as monitor. Recently I bought an Acer B227Qbmiprzx. Noticed I had this short Displayport to HDMI cable that does not have an active adapter on it in my stash. First of all, I got signal with white dots randomly spread flowing around. I thought may be the timing signal ain't set in yet. While I was trying to find Auto-setup button, screen began to get smaller and disappear with a boop sound. I thought may be it's not compatible or did not slot in correctly. I removed cable, tried again, no signal began to appear.
I switched to my active Displayport to HDMI adaptor. It was slow but the signal was going through. After a restart, it stopped working. The graphics card is MSI RX 570 Armor 8GB OC. It has 3 Displayport. None of them worked. During boot I would get a 640 x 480 bios logo screen. That's all. After initial boot sequence is gone, no signal.
I also tried:
Windows says that:
I did not try to reset VBios, yet. MSI tech support gave me a ROM but they told me that if I brick it, that would void the warranty. Also, they added that they do not give support to 3rd party port changing adapters.
Right now, I get 1.62G bps x 4 signal from my Displayport, sound is delivered and adaptive sync enabled as well. This makes me believe that Displayport is not ruined, may be the protocol used is ruined. May be the graphics card is keeping the transfer information and tries to replicate that whenever I try to use the adapter. I am also totally sure that this is not a Windows issue.
I would like to hear how actually these adapters work. Does GPU keep the data or the chip in cable keep the data? I read Displayport can be wired to native HDMI directly but this event makes me think it cannot be.

Tried TV to get signal, did not work.
Enabled iGPU and tried to get Displayport signal from it, it did work (only with active adapter).
Found a regular Displayport cable, it worked both on iGPU and RX 570.
Tried regular HDMI on RX 570, it worked.
Tried DVI to HDMI on RX570, it worked.
I also tried:
- Resetting Bios,
- Leaving PC powerless overnight,
- Disable CSM.
Windows says that:
- There is a connection coming from a monitor.
- The monitor is Generic non-PnP monitor.
- Monitor resolution is 640 x 480 (probably this is wrong since even if I set all outputs to show the same with 640 x 480, there is nothing appearing.).
