So I've been using a monitor via DisplayPort through the past week with no issues. Suddenly today, I turn on my laptop and the port is no longer detecting any monitor at all. I'm willing to troubleshoot this using any links or advice provided, please help.

I've tried restarting my computer, plugging the port in/out, plugging my monitor in/out... this problem seemed to have occurred out of seemingly nowhere. Any advice is appreciated, thank you.

A:Windows 8 not detecting DisplayPort Monitor

Alright, figured it out.

I'm guessing, that I probably set my external monitor to deactivate before unplugging it. The next time I plugged it in, it wouldn't activate at all for this reason.

I solved this by switching the way it got input from my laptop, going from DisplayPort to HDMI. Then I reactivated the monitor, and was able to switch back to DisplayPort.

In my personal opinion, this is truly the most idiotic thing I have dealt with so far in Windows 8. Hopefully display options such as "deactivate" don't stick around after unplugging them in the next iteration of Windows.

EDIT:
It happened again. Did some more research and the solution here worked:
ASUS PB278Q 1440P MONITOR "DISPLAY-PORT: NO SIGNAL, AND HDMI: NO SIGNAL" GTX 780

Relevant comment:
There is a feature on newer motherboards in which they have sleep state settings outside the control of the operating system. Go into your bios and go to APM configuration. Look for ErP setting (default is usually disabled) and enable it to S4+S5 sleep state. This solved my problem, now my monitor will show a display after computer wakes up from sleep or when powered off.

I have upgraded my HP Pro X2 612 laptop to Windows 10 and installed all the necessary drivers.

Neither works. I also removed pin 9 from the VGA side of the cable (15 pin cable, reduced to 14 pin).  I removed the pin because I heard that some cables send voltage thru that pin, and shouldn't. Nothing works. i have tried it on a Planar vga only monitor, a Samsung VGA monitor, and an LG TV (vga connector), all of which work with other equipment.  The hdmi to hdmi connection works just fine. i have spent hours and am very frustrated.  Any hints or help is  greatly appreciated.  I'm about to go to the dark side (Apple).

I recently bought an HP Envy 32 monitor and hooked it up to my Mac mini using a mini DisplayPort (i.e. Thunderbolt) to DisplayPort cable. The video works fine @ 2560x1440, but I have no sound.

Are there any adapters to do this or ways to do this? I can't seem to find any.

I am buying new monitors, the dell u2414h. Now, while this does have hdmi, I will be connecting multiple monitors together to extend the display from the laptop to give me multiple screens. The problem with this is that it only works if you use displayport and not hdmi, so I need a way to convert the hdmi to displayport or mini displayport.

I will primarily be using these monitors with my laptop that has displayport, so that is why I am getting these monitors and that won't be a problem. I will most likely hook up other laptops to the monitors and hdmi is way more common from what I have seen on laptops than displayport and is why I need a way to go from hdmi to displayport or mini displayport.

Any ideas? Thanks.

Hi there. I am working with two monitors. The first is a ViewSonic VX2250wm LED monitor, connected to the desktop (Lenovo ThinkCentre M90p) via aDVI(in monitor) to Displayport (Desktop) cable. The card is an Nvidia Geforce 310. The second monitor is VGA. Every so often, the ViewSonic's signal goes out. At first I thought it was the DVI/Displayportadaptor, but upon getting a new cable the problem persisted. I then assumed it was the latest Nvidia driver update, so I rolled back. The monitor's signal returned for a few days, but then eventually lost its signal again. This process repeats every time I install an older driver: the monitor comes back, but eventually dies. I am trying to figure out what is the cause of this problem. AFAIK it cannot be the Displayport as the Geforce is compatible. I have concluded it must be the ViewSonic monitor. Any help as to what may cause this loss of signal would be appreciated. I have a feeling it might be because I have not used an 'active' adapter and only have used passive ones. I just wish this information wasn't so vague and hard to find.  Displayport hasn't really taken off that well, has it?

Hi Everyone,

My 3 monitors are all the same brand (Dell) and model (U2212HM UltraSharp), they each sport 1 x DisplayPort, 1 x DVI & 1 x VGA connection.

As all of my monitors support DisplayPort I see no need for a DisplayPort adaptor, and I have connected my monitors as follows:

1). DVI
2). VGA by way of DVI Adaptor (this is because I am using a KVM switch)
3). DisplayPort

Ironically only the 3rd, DisplayPort connected monitor is not working with EyeFinity! I have manually set the connection on the monitor (through the monitor's menu) to DisplayPort. Further when I turn the monitor off and on I see the message: "No DisplayPort - so the monitor doesn't "believe" that it is connected.

Windows (7 - x64 - Professional) on the other hand responds to the monitor being turned on and off by making the long "doo doo" sound that it typically makes whenever a USB connection is established! However this being said "Screen Resolution" item only ever reports that two monitors are connected!

A:Can't get 3rd monitor to work with Eyefinity - it has DisplayPort!

DisplayPort can technically drive up to 3 monitors, but I am fairly certain that you cannot easily mix it's output with another digital output unless the video chipset can allow it (and this would be high-end, because DVI and HDMI are based on older technology and would require decent amounts of horsepower that a single GPU isn't necessarily going to be designed for). Nvidia makes some laptop video chips that allow splitting the signal between VGA and a DisplayPort port, but that's analog and digital, so it's a lot easier on the chipset than pushing 2 digital outputs at the same time (with content protection, scanning, etc. required by those interfaces).

The latest DisplayPort spec allows daisy-chaining of multiple DisplayPort displays on the same DisplayPort port from a video source, but to do so you need to purchase the requisite cabling or adapters to achieve multimon on the DisplayPort port and all devices along a DisplayPort multimon daisy-chain must be DisplayPort 1.2 spec or higher devices.

There are adapters that you can purchase that can take a DisplayPort signal and output it to multiple DVI endpoints (which could then be downgraded to VGA with an adapter on the DVI port), but you generally need to be driving the same monitors at each endpoint too which can be a pain.

My motherboard and monitor support HDMI and DisplayPort but I've only ever gotten them to work as my secondary displays. In the past I ignored it because I had multiple monitors and could just use one with DVI and it would boot on that one and when it popped up with windows it would change my main display to the other one which was using DisplayPort. Now I only have one monitor and both DVI and DisplayPort are plugged in but only DVI will work. It is the same monitor that worked as a secondary monitor with the same DisplayPort.

Hi all,

In a few weeks (I can't wait! ) I will replace my laptop with the Surface Pro.

Right now, though, I have my laptop connected to two monitors: One via VGA and other via DVI. I'm running Windows 8 Pro x64, so this all works great.

So the big question is whether it is possible to have multi-monitor support via the one-and-only DisplayPort that is on the Surface Pro? If so, what--if any--additional hardware would I need?

When I'm docked at home and using my Surface Pro as laptop, I really need to keep the functionality of using both external monitors (one is 31" and the other 29"). I would really hate to go back to only being able to use one.

If you can provide any insight, I'd appreciate it.

Thanks!

A:Multiple Monitor Support Possible via DisplayPort?

http://www.displayport.org/faq/

there are 2 options:

1) DisplayPort v1.1a hubs available today that allow you to connect multiple monitors to a single DisplayPort connector. Various output configurations are available for these hubs including DisplayPort, DVI, and HDMI.

2) you need DisplayPort monitors that support daisychaining. DisplayPort v1.2, supports monitor daisy chaining.
DisplayPort v1.1a displays are fully compatible with DisplayPort v1.2 PCs and graphics cards. A DisplayPort v1.1a display can be the last display in a DP v1.2 chain.
Here’s an example:
A PC with one DP connector is driving two monitors via daisy chaining. The 1st monitor is a DP v1.2 monitor with input and output connectors. The 2nd monitor is a DP v1.1a monitor. DP v1.2 PC—> DP v1.2 monitor with in & out connectors—->DP v.1.1a monitor.

Hello & thank you in advance for your assistance.

A month ago I installed a new Sapphire HD Radeon 7790 1GB DDR5 Dual-X OC GPU & began experiencing BSOD issues with driver atikmdag.sys. Would quite often go as long as a week between BSOD.

The BSOD seems to be associated with DisplayPort attached monitor. Have two monitors attached via Dual DVI which work fine. Can stream no problem. The third monitor which is attached via DisplayPort seems to be the culprit. Streaming The Mentalist on CBS.com last night on that monitor & it crashed right away. Watched Mentalist on another monitor with ease.

Have been working my way thru AMD Article Number: 27116 attempting to resolve this myself. Several driver versions with same results. Always use the AMD uninstall utility (restart), Driver Sweeper (restart) & CCleaner for good measure before installing next driver. BIOS is current as are Windows 7 updates. Have a 500W PSU, the GPU came overclocked from the factory & I did down clock for a short time which did not help. The GPU runs cool in the low 40's, the new PSU runs about 20 degrees hotter than the Dell OEM PSU. But it was crashing before with the cooler running 360W Dell PSU. Sapphire recommends a 500W PSU for this GPU even tho the 7790 uses less energy than the ATI Radeon 4850 it replaced.

Well it's a bit odd that I would come across this info now after a month and a half but - apparently there is an issue with the 20 pin on displayport cables. The infamous pin 20 issue.
To be fully compliant a displayport cable must not have pin 20 wired through.
The monitor is feeding power down pin 20, and the video card is feeding power out as well and the some video cards don't like it, (the power feed is to provide power to active converters, DP to VGA, HDMI etc.)

- On boot, until the Windows login screen comes up (Windows 8.1), there is nothing on the non-primary DVI monitor (so my setup is my primary monitor is one of the two DVI monitors, and then the left and right monitors is another DVI-only and the DP monitor).

- If the monitors go to sleep, or I put the computer to sleep and wake it up, any windows that were on the non-primary DVI monitor are moved over to the primary DVI monitor. Windows on the DP monitor do not move in this configuration.

- WIthin CCC, after sleep / monitors off, I have to restart CCC's control of the color settings for the non-primary DVI monitor. (I'm forgetting what the actual button says, but it's the button under the Display color controls settings where you can manipulate the R/G/B channels - I have to use the GPU for color matching since the monitors don't have any inherent ways to change R/G/B levels
If I only connect the two DVI monitors this is not an issue.

If I connect one DVI and the DP monitor, after sleep/wake any windows that were on the DP monitor are moved over to the prima... Read more

A:Having issues w/ Triple Monitor Setup (DisplayPort issue?)

I run a triple monitor setup on my desktop PC. 2 DVI and one HDMI on my GT 640. The one using HDMI goes as follows Mini HDMI on video card to normal HDMI to HDMI to DVI adapter. What I notice is regardless of which monitor is set as primary my BIOS POST screen and the initial Windows Boot screen always shows on the same monitor on one of the DVI ports. The video card determines what monitor the POST screen shows on. For me it depends on how many monitors I have plugged in and what ports they use. I have never seen it where it didn't show. The logon screen then shows on my Primary monitor. I don't use sleep or hibernate so I can't help you with that. Why you don't see your POST screen I don't know, I have seen other people report the same thing though. I don't remember if they found out why though.

I am currently troubleshooting about 15 laptop/docking station/dual monitor combinations all with the same issue.  When the laptop is sleeping and then docked the displayport monitor will not wake up.  It has to be unplugged and replugged into the docking station each time.   The second screen plugged in via VGA does wake up as I can move the mouse on it but the DP screen will continue to sleep. The setup:   Elitebook Folio 1040 G3 docked into a HP 2013 Ultraslim docking station.  2 monitors, both dell, one connected via Displayport the other VGA.  The monitors are some variation of a Dell 1914s. Steps taken to try and fix:1)Updated ALL drivers on the computer.2)Updated Docking station firmware (2.30), bios firmware, monitor firmware.3)Installed Displaylink and ran the configuration tools.4)Disabled DDC/Ci on the monitors.5)Ensured the monitor is set to the DP and not auto select.6)Installed the monitor drivers to look for additional settings Nothing I have done has had any change.  Any help would be greatly appreciated.

Often when I initially turn my computer on I get the message from the latest AMD driver:
"The System has detected a problem with the connection between your computer and the DisplayPort display that will prevent you from using the highest resolutions and/or refresh rates." and my 4k monitor would be in 30 hz not 60hz. To fix this problem I either reset my computer or reset the monitor and most of the time it will then go to 60hz. I have already tried a new displayport cable, fresh installed the video drivers and face the same problem. Can anyone help please?

Hey, I had the same problem and I just solved mine, so hopefully it will help yours too.

All I did was unplugged the power cable for 5-10 seconds. After I did that Windows prompted me that "You must restart your computer for these changes to take effect."

Once I restarted everything was fixed. Hope it helps! Good luck to you!

I have just taken delivery of a T470p and have done a fresh install of Windows 10 Enterprise and updated that to version 1703 build 15063.540. The T470p replaces an aging X240. I used the X240 with a ThinkPad Ultra Dock type 40A2 (P/N SD20F82750) with 2 ThinkVision LT2452p monitors attached via DisplayPort. Everything worked reasonably fine with the X240 docked - both monitors ran at 1920x1200 resolution. I'd get the occasional problem where I'd have to open and close the X240's lid to force it to realise it was docked, but I could live with that. But...if I dock the T470p then neither monitor works. Both monitors' power LED turn green when I dock the laptop (so I assume the dock and the monitors are talking to one another) but they then turn orange and there isn't a picture on either monitor. If I unplug one of the DisplayPort cables from the Ultra Dock one of the monitors gets a picture, but as soon as I plug the cable back into the dock the monitor goes blank. Is this a known problem? My employer are about to order 40-50 T470p laptops but if we need to purchase new Ultra Docks as well I think we will have to have a rethink. Kind regards, /Neil

Everything is working except - no sound via monitor.  Have updated audio drivers,  Suggestions??

A:Yoga X1 ThinkPad thunderbolt LG Monitor Connected via DisplayPort - No Sound

You might need to enable it. 
 
With the monitor connected, turned on and displaying your computer's desktop:
 
Right click on the speaker icon in the taskbar and select "playback devices." 
 
In the white area of the dialog box, right click and make sure both "show disabled devices" and "show disconnected devices" are both checked.
 
Right click on the various playback devices to make sure they're all enabled. 
 
If you start something with audio, you should see the little green "meters" bouncing on one of the devices. Right click that device and set it to default.

After having worked for more than 1 year in double screen, I started to have flickering problem on the external monitor, connected from mini DisplayPort to DisplayPort on an external ThinkVision Monitor.I do not know how to troubleshoot. Below is a video of the issue.As a hint that the card might have some problem, sometimes the PC takes about 30 seconds to decide the graphic mode when the screen is turned on.I would like to understand how to troubleshoot the issue, determine if it can be- hardware failure (pin, chip damaged)- driver failure (but I have driver at level 10.18.14.4432 which seems the latest)and understand what should be repaired.any suggestion is very welcome, thanks for your attention,xgiannak

I plugged a 2nd monitor with the upper VGA port of my computer but the computer don't recognize this 2nd monitor.
How can I do ?

A:Top, upper VGA monitor video port does not work (HDMI, DisplayPort)

Sounds like you have a graphics card installed, if so, the built-in ports are disabled.   I suggest you use the other port on the graphics card.

Hi Peoples,
I just received my new Dell UltraSharp u2412m monitor!
Now I try to connect my Dell XPS15 laptop (via its mini displayport connection) to my new monitor via a mini displayport to displayport cable.Sadly it doesnt seem to connect and the monitor instantly goes into Power Save Mode...
What am I doing wrong here? Is this possible/compatible in the first place?
Thanks very much in advance!
Moris
Ps. the monitor instantly works with an old laptop via vga connection...Plug and play...

A:Problem connecting my XPS15 laptop to my u2412m monitor via displayport

Try using a different connection--hdmi would be best if the laptop has that. You can use a hdmi to dvi cable--same technology and those work. Those can be bought for less than $10.

On the XPS 15 9550, can an external monitor with Displayport inputs be connect directly into the laptop's USB-C Thunderbolt output using a straight miniDisplayport-to-Displayport cable?  Similarly, can a miniDisplayPort to VGA adapter cable be plugged directly into the USB-C Thunderbolt port to drive older monitors/projectors? Or is the TB15 Dock mandatory in order to get the computer talking to  external video devices through its Thunderbolt port output?

My daughter has a M91P model 7052-A9G serial number S4VEK82 running Windows XP SP3 for compatibility with legacy software.  Her existing monitor is connected via VGA and she now wishes to use a Dell U2715H for better definition.
When she connects the new monitor to the display port on the M91P it is not recognised by the system and the video is still only active on the VGA port.
She is 80 miles from me and I support her using Team Viewer which enabled me to switch the desktop display properties to digital but still no output on the Dell so I changed it back to VGA so that she could work.
The new monitor and display port cable has been tested on a friend's computer where it worked OK.
 
Has anybody met this before and how did you resolve it.
 
Many thanks, Firkle

A:ThinkCentre M91p: will not connect to Dell U2715H monitor via DisplayPort, no signal (DP ver. 1.1)

When I Googled for your problem, I found this on the Dell forum.  The built-in Intel graphics on M91p has DP 1.1: 
 



RE: U2515H - "no signal coming from your computer"





This happened to me when I enabled DP 1.2 option in the menu.
If that is the case, you do not have a DP 1.2 compatible hardware and software/OS. (perhaps if you are using a linux machine)
 
When your monitor tells no signal... push a menu button for about 10 seconds. It will show you other input sources, keep pushing. Then it will bring a menu to disable DP 1.2. Disable it. Restart the computer.
Hope this helps

I have a Lenovo M93p model 10A8, connected to a 2560 x 1440 monitor via DisplayPort.  When powering up or rebooting, I never see the Lenovo splash screen, so I can't enter the BIOS.  If I connect a smaller monitor via VGA, I can see the splash screen and can enter the BIOS OK.   Obviously, it's a PITA to connect another monitor in order to enter setup (or select an alternate boot device).  I've tried tapping the F1 or F12 or Enter keys during boot, but that just prevents the computer from booting at all.  Any suggestions on how to fix this?

Ok.. I'll try to keep this breif. I bought this laptop SPECIFICALLY for the capability to run 2 external monitors via Thunderbolt 3. I have spent thousands of dollars on the laptop, monitors, and cables and put hours of research into making sure everything was compatible and it won't work.  My setup is as follows: Thinkpad T580 with TB3 portTB3 to Dual DisplayPort Adapter(x2)Monitors are both 32" Samsung 1080P monitors at 60hz (NOT 4k) Here's what I have done: Updated display drivers directly from Intel(newer than Lenovo provides)Updated BIOSUpdated FirmwareBought MULTIPLE adapters thinking it was possible an adapter problem.Bought MULTIPLE cables thinking it could be a cable problemI called Lenovo tech support and, after 10 minutes of convincing the tech that my laptop even has a TB3 port he obviously was unable to resolve it so I was mailed a new motherboard and a tech came to my house and swapped the board out. Same issue.  The laptop detects only ONE monitor at a time. If I plug them both in to the displayport adapter, one of them will work, the other will say it's not connected. If I unplug the monitor that is on, the previously undetected monitor will immediately be detected and turn on.  If I plug the undetected monitor into the HDMI slot it will detect and output. But this is NOT the functionality that I have spent thousands of dollars for.   I am out of ideas and now quite sure that, even though the marketin... Read more
