Question Display port no signal. HDMI working fine.

[GatiZ]

Hello iv'e recently switched from a AOC 24" 144Hz 1080p monitor to a Minifire 24" 1440p 180Hz monitor.

After turning on the new monitor and connecting it VIA DP it shows no signal and turns off, If i connect it with HDMI there is no problem. The main problem im facing is that the HDMI supports up to 144Hz and i would like to use everything that i paid for. I was running the previous monitor with the same DP cable as this one and it was working as it should. Since then i have not changed anything in my pc's hardware.

So far iv'e tried:
Using different DP cables.
Using different ports
even using another minifire monitor (Same model)
Disconnecting the monitor from the power source
Disabling HDCP

PC Specs:
CPU: Ryzen 5800x3d
GPU:Rx6700XT
RAM:32GB patriot 3200Mhz
PSU: Thermaltake 700W

My suspicion is that there is something either in the OS or the AMD software interfering with some settings.

Thank you.

drivers from amd.com up to date?
bios of motherboard as well?

Do you still have the aoc monitor? Confirm DP still works?

If aoc monitor + DP cable does still work, it's not your computer. Have a look at the DP input of the Minifire monitor and just check the DP plug housing, the plastic part for both DP cables since you've tried multiple, isn't touching anything on the monitor. DP plug can sometimes feel like it's locking in with it's two latches but connection may not be completed.

This recent thread was regarding his case interfering with DP ports of his graphics card. I know your DP ports work so obviously case isn't the problem, just showing you that at least with them, the DP plug seemed secure but wasn't. If there's a clear gap with Minifire monitor and DP connection I'd have no idea at that point.

Question - DisplayPort only works in the PCIE4 slot not PCIE1

Last week, I upgraded my monitor, and to use all its power, I started using the DisplayPort connection on my GPU. My motherboard, a Asrock Fatal1ty B360M Performance, has two PCI Express 3.0 x16 slots, but for some reason, I only get video from PCIe1 when I use the HDMI port. Both the...

Hello, i have just confirmed the DP works on the AOC monitor.
You mentioned the minifire monitors DP plug housing, and it was quite sketchy from the beginning.
As you can see in the pictures:

The HDMI seems to sit more snug than the DP cable but ive pushed the dp cable as far as it pysically goes.

Can see DP plug touching the monitor, wouldn't be surprised if it's not fully connecting. If you can try hold it in with a bit of force then turn on monitor while doing that if it shows a picture or not.

get a smaller dp cable

I have tried to hold, and move it in different directions. And switched to a smaller cable. But to no avail. Upon further investigation i noticed that the DP is higher/closer to the frame than the HDMI. And also twice as big. but from what i checked the cable still moved around and it was not being pressed against the monitor at such an angle that it could interfere with the connection. Yes it's a very tight fit. Maybe there is a 1 or 2 degree angle which the DP cannot reach, but i think that it should not be the reason the cable is not working, After all. the original cable was provided by the manufacturer of the monitor and should work with it.

Yeah, true. Would hope that there is some quality control also.

Tried having a look at the manual for something on faq/troubleshooting, I can't read the language. Maybe you can or try contact them on the matter.

Can you try the monitor elsewhere, friend or pc store? While there, try a different DP monitor if possible.

So i contacted the manufacturer and found out that multiple people have stated that they have a similar problem. They recommended to either get a shorter/smaller DP cable. Or to Just yeet it and force the DP cable as hard as you can. They stated that it usually requires way more force than other monitors. And the second option worked, But it required such big force i thought i was going to break it and just relied on the fact that i have another port just in case. So i put the monitor laying down against a wall started forcing the DP cable as hard as i could and prayed to god it doesn't push the whole backplate in. Then i heard a pop and voila. Something might've broke but at least now i have my DP.
