No signal using DisplayPort (no problem with HDMI)

lLord_Thanatosl@reddit

I genuinely don't understand cause my monitor isn't displaying dp regardless. Took it into my local shop to see what was wrong, but it immediately turned on and gave display immediately via dp. Now that I'm home, have everything connected again and boom same as before not detecting the dp.

Danmarm@reddit

I know this is gonna sound stupid but I flipped the 2 ends of the cable. Switching them. Somehow it worked, I tried everything including what they said on this post.

P.S. I have a Huawei Mateview GT 34" a rtx 3070 Gigabyte and a z690-Pro from MSI if that provides any help.

Elite_Reaper101@reddit

Bro listen, I spent about 3 days trying to understand why my monitor was not getting display output. I literally followed every guide there was, I am not even kidding. I have even came to this exact post multiple times and have seen your comment multiple times. And every single time I thought I might used like 3 dp cables 2 hdmi cables did this and that changed things so many times, for sure this is not gonna work for me and I skipped it every single time. But bro this works my god I don't know how much to thank you!!!!!! This is so stupid simple and yet this works and I feel dumb af. But thanks man, thanks a lot!!!

Academic_Ambition737@reddit

I love you, I guess its not common knowledge that dp needs to be in a certain orientation gif , tried to figure it out for 2 hrs till I turned to reddit, helped me cable manage I guess lol.

[-]

gumring@reddit

I’m glad I found this, it bloody worked!

[-]

Simply_AnotherUser@reddit

I think this worked for you because it cause your monitor to reset in some way, the same way other suggest the power cycle, whic is what has been working for me.

[-]

PatientChest9774@reddit

The f**k? This actually worked for me 😅. I bought another cable, updated the drivers, and did a system restore. None of them worked until I tried this. This is just weird, but if it works, it's not stupid. Big thanks to you!!

THIS WORKED FOR ME THANK YOU SO MUCH

Oh my god that actually worked, and I was about to start looking at new Monitors/GFX card.. had already invested in a new DP but no connection, swapped the cable around et voila, 240hz signal.. ❤️

nonytb@reddit

i had been using my monitor setup for over a month with no issues until now and my display was still properly working with my other laptop. i tried everything else on this thread and THIS is what fixed it - even though that cable orientation was functional before. you're a real lifesaver danmarm

this just worked for me in 2024... I switched the ends of the cable and it worked after days of not working... using xiaomi 34" 180hz with a 2060 super.

Well this post is a year old but i hope this helps anyone passing by If you tried everything and couldnt figure it out but if i found a post on microsoft support saying that if you plug both HDMI and DP cable and you press WIN+P and you use your UP and DOWN arrow keys to select every option ( like a trial and error type of thing until you find something that works) your screen will eventually flash or turns black for a couple of seconds until you get image on your screen.

I know this comment is old but dude thank you so much! Absolute legend <3

llllllllllllllllll19@reddit

Arrived here from a Google search, on day two of my struggles with DP. I tried your solution and finally got an image. It works! Both Windows and AMD Software display settings show the feed is coming from DP.

Then I pressed my monitor's settings button and saw it was still feeding from HDMI 2.0, so no biggie, I decided to switch it over to DP.

And immediately my screen went black except for "No Signal".

But after 2 days, I found a solution! I unplugged the Display Port cable, cut it with a pair of scissors, and threw it in the garbage where it belongs. I'm going back to HDMI.

Because over the past 20+ years, whenever I plugged my HDMI cable into my PC, I saw an image right away 99.9% of the time . When I plug my DP cable in, I have to go through 25 problem solving scenarios that eat up hours of my time, might potentially DAMAGE my brand new monitor with the continuous flickering on-and-off, and none of which actually work.

After this debacle, isn't it pretty obvious why HDMI 2.1 is the standard for all the new gaming systems?! DisplayPort is crap, and if I have to "suffer" through 144fps for the next few years using HDMI 2.0 instead of 165 or 240 with DisplayPort, then so be it. 240fps means shit to me when the method or doing it takes me literally hours of trial-and-error and still gets me nowhere.

Anyone here from Google, please take my advice: Immediately return whatever you bought that uses DisplayPort, don't buy anything that uses it in the future, and if you want high FPS, only buy stuff that uses HDMI 2.1

[-]

Natural_Technology41@reddit

I mean if your control panel shows that GSYNC ou FREESYNC is available that means your DP is working and everything is as it should be. Switched from console to pc and most of my experience was fixing dumb and obvious shit like this one right here where it takes only 2 keys to fix, almost broke/changed my monitor and bought 2 more cables just nothing basically.

[-]

ReptileAlyx@reddit

Almost one year and this saved me. I had to open Nvidia control panel.

One monitor was not set up to work with multiple displays.

Thx

[-]

Gunslapper@reddit

What are you referring to here? Can’t find a setting like that.

[-]

Simply_AnotherUser@reddit

In what part of Nvidia control panel you found that setting exactly? I have dual monitor configuration and I have not any option as the one you ponted out anywhare in Nvidia control panel at all.

[-]

SimplePuzzleheaded80@reddit

After two days of dealing with this...I agree!

[-]

Beadsifyy@reddit

what about the higher refresh rates with the displayport cable?

[-]

DisastrousAd9319@reddit

I know this is old but man this is a trash take. Dp is far superior to admit in almost every way.

[-]

Darth_Liberty@reddit

..except for "working reliably" - which is kind of important.

[-]

Carreb@reddit

Why the fuck does this even work, thanks so much it fixed the issue for me.

Context: My DP signal would randomly dissapear and the monitor would say 'no signal found'. Replugging the cable fixed the issue for a few minutes before going black again. This WIN+P cycle fixed the issue.

[-]

Mr_Eik@reddit

I feel so stupid now, thanks tho

[-]

Responsible_One_9104@reddit

Am I stupid? I dont know what to do and it doesnt work...

[-]

Natural_Technology41@reddit

Try changing your DP cable and try all over again, plug in your HDMI and DP cables and press WIN + P and hopefully that should do it.

[-]

AlpsLanky209@reddit

4 hours trying hundreds of those solutions and this one w WIN+P worked. Thank u sm bro

How do you stop a speakerless monitor beeping. Plugged in or not, it beeps. 4 times. Not really a beep. But ill call it a beep.

[-]

DrPentaMerosu@reddit

I know it's been years, but maybe it can be useful to someone in the future.

after hours of troubleshooting I finally discovered that the monitor's power cable had probably gotten a little loose.

unplug and plug all the cables (including audio) and like magic it works.

[-]

Altruistic_Elk6610@reddit

Tried 20 different things and yours worked thank you bro!

[-]

Jolly-Brick-952@reddit

I have had this problem happen to me twice. I took me a while to fix it. The thing that worked for me was unplugging both my pc AND monitor. Leaving it for about 30 seconds then plugging it back in. I have an Asus VG248QE monitor and apparently it’s a common problem with it

RealMenChewGum@reddit

u/doglatemlive66 I know this is an old thread, but did you ever find a solution to this? I have the same issue using the same monitor - HP 27XQ. Displayport shows as inactive no matter what I do while HDMI works fine. The solution mentioned in one of the comments below (pressing WIN + P while both HDMI and DP are hooked up to the monitor) doesn't have any effect.

[-]

doglatemlive66@reddit (OP)

before turning on your pc, unplugging the monitor from the outlet wait a couple of minutes to let it reset and then plug it in and turn the pc on.... tried it and it worked! but if I will have to do that everytime I turn on the pc I´ll probably switch back to HDMI...

hey man no problem,

I actually dont remember but at the time this worked :

"before turning on your pc, unplugging the monitor from the outlet wait a couple of minutes to let it reset and then plug it in and turn the pc on.... tried it and it worked! but if I will have to do that everytime I turn on the pc I´ll probably switch back to HDMI..."

but from that time I didnt have to do it repeatedly... I am still using the DP and its working without any problems... but I dont think I did anything else it just kind of worked out, hopefully this helps

[-]

Simply_AnotherUser@reddit

I have had this same issue coming back intermitently along the past two years and since last sepetmeber again and it's driving me nuts. Do you have any idea of what could be causing this? I'm pretty sure the flaw isn't in my DP monitor, cables or graphics card... Some weird thing coming from Windows Update maybe?

[-]

just_cool_guy@reddit

That's the only solution that worked, thank you!

[-]

Dyno_122@reddit

Very odd solution but if here's something that worked for me.

Turn off the computer and either unplug it from the power source or turn off via the Power Supply's power switch.
Turn off your monitor and then unplug it from the power source.
Wait 30 seconds.
Plug the monitor back on, turn it on if it doesn't do so automatically.
Plug the PC back on or flip the PSU switch back to on.
Turn the PC back on and if this fix is applicable, your Display Port will now work again

[-]

Simply_AnotherUser@reddit

I'm having this same issue out of nowhere since last month, and this method has usually enabled the DP recognition again fot me, but as soon as I put my PC in sleep mode, next time I wake it up the same problem appears again. Any idea of what could be causing this? I'm suspect it could be related to any update from windows update since for what i've been checking this isn't a flaw from my monitors, cables nor graphics card.

[-]

Soggy_Grapefruit_768@reddit

So one day I just turned on my PC and my main monitor (the Display Port monitor) had no signal, I tried all of these other solutions but none of them worked. I plugged my HDMI cable into my main monitor with the Display Port cable still plugged into my main monitor.
However, it was as simple as Pressing 'Windows + Ctrl + Shift + B' to restart my display drivers and it automatically switched from the HDMI signal back to the DP signal.
Hope this can help someone.

THEPiplupFM@reddit

holy shit this worked, thank you!

Key-War7953@reddit

Wow!!! Thank you!

[-]

A_1337_Canadian@reddit

One solution that no one brings up is to make sure it's the right type of cable. I'm just a layperson but there are DP -> HDMI cables that cannot be used as HDMI -> DP. So you could've bought a DP -> HDMI cable but are trying to use it as HDMI from the source and DP as the screen. This WON'T work on this type of cable. You need to get an "active" one.

[-]

HellhoundSin@reddit

Another stupid solution after a few days thinking my gpu was defective. The position of the connector was too close to the case, so it was not completely connected. Well, since it was "defective" I decided to force it, then I heard a "click" and magically there was signal.

Extrocate@reddit

For anyone using a display port to usb c cable on a laptop, make sure your laptop didn't randomly disable the usb c port. You can turn it back on by holding down the power button for 20 seconds while the laptop is turned off

[-]

hexress@reddit

Holy shit you saved me after an hour of searchng!

[-]

Extrocate@reddit

Glad I could help, took me multiple weeks of testing and replacing cables to figure out what was wrong

[-]

hexress@reddit

So I guess this was the fastboots' fault, right? It turned off usb-c during low power, and as it didn't fully had to boot again, it didn't bother tu turn it on I guess.

[-]

Extrocate@reddit

That could be it. I haven't went back and tried to figure out why it happened, but I do remember messing with fast boot

[-]

hexress@reddit

Seems likely, I'va had some more weird (not that broken) things happen after my laptop turned off from low power. Most of them were system errors (like explorer.exe and window manager bugging out so that I couldn't even restart from within the system). I see I have a bios update availible, might try that.

[-]

teeroh@reddit

All of the shit in this thread did not work OTHER than switching the two ends. Ridiculous fix but it worked lol

[-]

Disclipedd@reddit

then the same problem happened again for me

[-]

Glum-Dot5558@reddit

Slightly different problem. I had the same notification stuck on the top right hand side of my screen "No signal using DisplayPort". I could still use my screen behind that notification but was obviously obnoxious sitting there taking up part of my screen. I reset the monitor settings using the buttons on the monitor and that fixed it.

Coming here from Google after three days of issues.

There was a solution posted below to boot your PC with the DP monitor unplugged, and then plug it back it in after a few minutes.

It worked.

for those who want to use dp individually, read this. plug in both hdmi and dp and duplicate the screen using win + p then open amd software and find global display then enable gpu scaling for display 2 which should be dp and you switch to display port using win + p. hopefully it helps.

Or simply unplug the extra hdmi u have that tends to split up ur apps in different ports

Responsible_Topic669@reddit

If it doesn’t work , try 4 repetitive presses on ur power button on ur pc , that will either start up the computer either in bios or bring u to Home Screen log in, if bios comes up , just exist from right side , and spam ur mouse till the screen logo comes up, if screen logo blinks , its a indication ur going back to bios if this persist , go to settings in left side bios, go to saved and logs, set back to default setting or choose exit, if ur brought back again to bios 3rd time repeat 2nd step 4 x until system reconfigures updating bios and you’ll be brought to a new blue log configuration where u can adjust what u want to do, I suggest you just left it recover and updated anything that the system found that wasn’t working and save changes and exist or restart computer , computer will reboot then press power button 4x n it should work
