Hi all, I am trying to connect 2 external monitors (Asus VW22AT) to my W550S laptop.Via the VGA connection, it works fine (for both monitors, i tried one by one), the display automatically sets to 1680x1050 resolution. My problem comes from the mini displayport which i used with DVI adapter (I also tried with VGA adapter), I can't get the 1680x1050 resolution, it recommands to use a 1920x1080 resolution but the screen is blurred. If I manually set to 1680x1050, the image doesn't use all the screen, each side is black on 3 centimeters thus the image is also blurred. Do you have any solution please?Best regards, Jean

Hey All,

So I'm running 2xR9 290X (crossfire) with 3xQnix Qx2710 monitors. One of the qnix monitors was purchased with HDMI/DisplayPort connectors along with the usual DVI connector (normally these monitors only come with the D-DVI input)

I had a 2 monitor (with just the two DVI-only monitors) setup for a while that was working fine.

Since installing the third monitor I'm experiencing several weird things:

- 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.

Hello all,

I have been having a problem with my monitor setup for ages and am now at the end of my tether...so need some help!

I have a Digimate L-1931W monitor, in plain speak, a 19" Widescreen TFT LCD monitor. The screen had been flickering (losing channels) for a while and I have diagnosed the cable as being the culpret (A VGA D-Sub, 15 pin cable). Change the cable you say...which I have done 3 times. Herein lays the problem.

This is where I show my staggering ignorance. The original cable seems to allow my windows XP machine to locate and install an appropriate driver for the monitor, and my Nvidia adapter has the monitor listed as a "M19W". Using any other VGA cable means that the monitor is listed as a "CRT" monitor in my nvidia control panel, and is impossible to change. Being CRT, it gives me no option to have the relevant widescreen resolution (in this case 1440 x 900), and also annoyingly flickers on and off as if it has a CRT gun! (when changing resolution).

Does anybody have any idea why changing a VGA cable would disable the plug and play driver installation from my monitor? Many thanks for any help.

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?

Basically my question is how do I change my default boot display to DisplayPort instead of DVI?
DETAILS
Looked all over and couldn't find a solution. My computer only allows me to boot up in DVI and nothing else. 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.

For some  reason the laptop doesn't seem to detect the monitor or vice versa. The monitor says DP cable no signal. Other inputs like the power adapter and the wireless mouse I attach to the docking station do work however. I'm not sure what else I'm looking at. I haven't tried using the other inputs like the hdmi (id have to buy an adapter) or the VGA and the one other one it has since I dont have cable for those... I'm not sure how to resolve this.

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.

Hi Everyone,

I am attempting to configure EyeFinity with 3 monitors. My graphics card, a PowerColor HD 6850 supports a maximum of 3 monitors, and it sports the following monitor outputs: 2 x DVI, 1 x HDMI & 1 x DisplayPort.

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!

Furthermore ATI Catalyst can only see two monitors connected - it sees one Analog (due to the adaptor) and one digital (as pictured below).

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.

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.

A:BSOD while streaming on DisplayPort attached monitor?

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.)

How a Bad DisplayPort Cable Can Ruin Ruin Your Day
For about 2 months I've been struggling with a BSoD error related to atikmpag.sys on my Windows 7, core i7, 2x 5870 Crossfire system.

Guess what? BSoDs continue!

Finally, after all of this, I decide on replacing the DisplayPort cable as the last possible point of failure. I should have mentioned that I'm running 1 native DisplayPort and 2 DVI ports.

Hello folks, I've got a number of HP Prodesk 600 G2 SFF work stations that are experiencing a problem with their displayport connections. When a monitor is connected via VGA there are no issues, but if you add a 2nd monitor or hook both monitors up through displayport the monitors flicker, and turn off at random. The workstations are all equipped with Intel HD 530 graphics chips, and are running windows 10. I've tried updating the drivers with HP OEM, as well as a number of drivers direct from Intel with no success. A call to an HP support technician ended up with him saying the motherboard needed to be replaced. If that is the solution, then so be it, but I find it hard to believe that so many workstations would have this issue out of the box. Have any of you run into this issue or something similar?

Hello folks, I've got a number of HP Prodesk 600 G2 SFF work stations that are experiencing a problem with their displayport connections. When a monitor is connected via VGA there are no issues, but if you add a 2nd monitor or hook both monitors up through displayport the monitors flicker, and turn off at random. The workstations are all equipped with Intel HD 530 graphics chips, and are running windows 10. I've tried updating the drivers with HP OEM, as well as a number of drivers direct from Intel with no success. A call to an HP support technician ended up with him saying the motherboard needed to be replaced. If that is the solution, then so be it, but I find it hard to believe that so many workstations would have this issue out of the box. Have any of you run into this issue or something similar?

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

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 an original series HP Spectre x360 13-4003dx with Windows 10. I cannot connect a vga display to the x360 Mini DisplayPort. I am using a miniDisplayport to vga cable from CableDeconn. Typing (Windows) + P, I try to switch to dual displays, either mirrored or extended, and also try to click on "detect display" but get the error message, cannot detect. i have rolled back the graphic drivers to the original install, and also updated to the most recent. 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). Please don't let me do it! Everything works so much easier (but with less flexibility and sooo much more money).

I am trying to connect the HDMI port on my nVidia GeForce GT 640 video card to the DisplayPort input on my HP Compaq L2206tm monitor. This is the reverse of what is expected by cable fabricators who have lots of cables and adapters for the opposite configuration, i.e., DP on the videocard and HDMI input on the monitor. There seems to be a uni-directional vs bi-directional issue involved with DP, but I don't quite understand it. Anyway, the uni-directional choices I am seeing are in the wrong direction. Anybody dealt with this and what is your advice for me?

I have a Mobile Precision M6700 with an NVIDIA Quadro K5000M GPU, and I'm wondering if it supports DisplayPort 1.2. I can't find any information in the Dell spec sheet or the owners manual, but the NVIDIA specs says it supports DisplayPort 1.2. Can anyone confirm this on the 6700?
The issue I'm having is this: I recently bought a couple UltraSharp U2415 monitors (which I've since returned for reasons unrelated to this post) and when setting the DisplayPort version on the monitors to 1.2 everything worked fine if I plugged in the cable after the laptop booted.
However, restarting (or starting from a cold boot), the laptop would not boot even to the Dell logo. It would start beeping (in an inconsistent pattern) and sometimes would flash a red border around the laptop and display and some text that disappeared before it could be read. Once or twice it did actually boot into windows but ran so slowly it was unusable.
Changing the DisplayPort version on the monitors back to 1.1 corrected the issue. This seems strange to me since I would have assumed the monitors would just not work, not that I wouldn't be able to boot the laptop. Can anyone shed some light on this?
Thanks.

I'm using a Surface Pro 2. After my upgrade from Windows 8.1 to Windows 10, I'm not getting any audio out from the DisplayPort.

I use DisplayPort to HDMI to a receiver. I've upgraded to the latest RealTek audio drivers, but it's not helping. Could there be a different driver issue at play?

Any suggestions appreciated.

I just got this M700 SFF desktop, which has 2 Displayports and 1 VGA output. The PC has Intel HD 530 Integrated Graphics. - Should I be able to use THREE monitors at "extended desktop" setting from 2 X DP + 1 X VGA? Right now, I am running One (Dell S2216H) Monitor from One of the Displayport via DP to HDMI adapter (since the monitor doesn't support DP input) and another same model monitor from the VGA output, using a VGA cable. If I try the second Displayport, it seems to show no output. I tried the same setup as the first monitor, DP>DP to HDMI Adapter>HDMI cable>Monitor; doesn't work. I tried unplugging the VGA connected one and run the setup, doesn't work. I shifted the working setup i.e. DP Adapter>HDMI to that displayport from the working one, the monitor doesn't get any input. In both cases, monitors connected to the last Displayport isn't detected by the graphics card or control panel. I have updated my BIOS to .....67 (as shown in Lenovo Support page) and changed the Display from PCE to IGD (as suggested in another Lenovo Support forum), but the BIOS setting doesn't show any option for "Enable Multiple Monitor Support" I have designated the DP>HDMI connected monitor as my primary display. - How can I get the other Displayport to work? - Can I use two Displayport output (via HDMI) to two monitors simultaneously at extended desktop setting? - How can I check/diagnose if that Displayport is correctly connected for giving any output at all?

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...

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.

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

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.
