Resolution of U2414H DisplayPort Daisy Chain/STD problem

Hello

I have what seems to be a common problem with no solution on these pages; with DisplayPort STD.

I had two of these Dell monitors over the weekend and spent about 3 hours trying to get STD to work with them. I arrived later, and they have worked fine for about 36 hours.

In this time my computer restarted two times without any problem. However, this morning I had upward, turned and suddenly the second (end of my STD string) string is not recognized as an instructor. It shows my desktop, but only at 640 x 480. AMD Catalyst can see it, but refers to it as 'No Display connected.

My setup is a Gigabyte Radeon HD 7950 feeding these two Dells (on a single string of DP STD), a Compaq Q2022a on HDMI and a DVI. The first dell also has a USB Bluetooth stick and WiFi USB dongles plugged, and the second dell USB tire this is the capacity of the first. Both worked absolutely fine when I went to bed, and this morning, the second in the chain was not.

I am looking to buy up to four more of them for a tri-moniteur stacked configuration, but I need them to be more reliable before I can justify spending that much! I love the thin bezel and STD is a must for the configuration I want, but reliability is essential too, I don't want to spend an hour a day fixing everything...

Thank you

For anyone interested, my workaround is the following:

-Unplug the monitor two monitor one

-Disable STD on monitor 1

-STD re - activate the monitor 1

-Reconnect the monitor 2 in 1

-Hold the power for about 8 seconds on Monitor 2

Seems to work after having done this, not.
Of course, a better solution would be for Dell to realize they sold a product of poor quality, do a recall and get fixed them correctly. This is currently my only product of Dell and if this is how their quality control, I certainly won't be getting more.

    * Press the Menu button of the monitor to open the OSD (On Screen Display). The bottom of the screen should display a resolution. This resolution should match the resolution of the default monitor. The two monitors: 1920 x 1080, 60 Hz

    * Brief description of the problem monitor? Monitors have been implemented following the instructions on page 25 of the Dell online manual to connect the monitor to function DP multi-flow (MST). DisplayPort cable is connected to V3900 output MiniDisplay port DisplayPort graphics card in the 1st U2414H; second DisplayPort cable is connected to the DisplayPort on 1 U2414H monitor output and MiniDisplayPort in the 2nd monitor U2414H. Dell U2414H drivers have been installed from the CD provided and both recognized by Windows. V3900 graphics card Driver is up to date with the EyeInfinity software. Source of input on both monitors the Mini Display Port value. Display settings on both monitors Display Port 1.2 value activate. Resolution of the screen on Windows 7 shows: (a) two separate Dell U2414H (mini Display Port) screens, with each resolution 1920 x 1080, multi (b) displays the value "to extend these displays. The two views work with Setup leading up to and acknowledged by the graphics card.

    Problem 1 - all the time - monitor power buttons are lit, the computer is turned on, then monitors lights don't - they show 'Power save mode' and then turns off. To hit the power button on the computer to shut down Windows. Only way to get these on monitors is unplug cords from the back of each monitor, wait a few minutes, plug in the power cord, start computer and then both monitors will start up and sign of windows to the screen will appear and monitors will work. Normal operations for a full day of work if you do not restart. If you need to restart during the day (like when you get a software update), the same thing happens. Start the computer to restart, but the monitors come back on not and remain dark. There is nothing wrong with the graphics card V3900. He is certified by AMD and DisplayPort.org to work in an environment of STD DisplayPort 1.2. I had previously two 215tws Samsung SyncMasters connected to each output V3900 Grahics card and they work very well in extended mode for years until a SyncMaster 215tw started shaking like crazy. A SyncMaster has been connected to the out display with a dongle and a DVI cable Port. The other SyncMaster was connected to the DVI output on the graphics card. So I decided to buy these two U2414Hs. Technical support Dell after many phone calls and e-mails finally advised me that there is a problem of "compatibility" between my computer and the U2414Hs and recommended that I return the monitors. On the web site of the U2414H AMD has not been certified by AMD to work in a DisplayPort 1.2 STD Set Up. Other former Dell monitors are certified by AMD to work in the Display Port 1.2 Setup. DisplayPort.org lists the U2414H to work with Display Port (it does not say that it will work in a DisplayPort 1.2 Set Up).

    Problem 2 - shift perceptible in the entrance of Microsoft Blue Tooth keyboard and mouse and PS2 Keyboard and mouse. All the drivers are up to date. When you type a phrase, it takes a few moments for the text displayed on the screen using a keyboard. Both the mouse connected and the Bluetooth mouse are unresponsive sporadically for a few moments until they finally react. It happens regularly during the day. The monitors provide excellent clarity when you work. The stand is ideal for office property. Before these monitors are returned if no one knows what causes these two problems and does anyone have a solution? Should I stop using the Display Port 1.2 and hang them using HDMI with active dongles? If I have to return these two U2414Hs, I considered the 2 two U2413s. Someone at - it all opinions on the last U2413s from Dell? I have read some real problems with ghosting that I just haven't the time for more. The remanence correction in the models of U2413 sold in 2014? There are very few monitors on the market with Display Port in and out to the back to support DisplayPort 1.2 STD Transport.

    Thanks for any input.

    I had to remove my VGA HDMI DV card and now the DP (display port) works very well. Don't need to use a HDMI cable. Display Port 1.1 is reported as the problem in order to remove the card solves this problem.

  • U2414H - question Daisy chaining

    Trying to get U2414H monitor purchased from Dell daisy chain with MS Surface Pro 3 (8.1) (all updates made). Driver for the monitor is also downloaded and installed.

    Have Surface Pro 3 dock miniDP to DP (en) U2414H then (out) DP / DVI on 3rd screen.

    I activated PD 1.2 on the Dell and I can extend screens of the Surface of the U2414H very well.

    I clicked on "detection" to see if it detects the screen which is attached via DP to DVI cable and it gives ONLY the option to connect via VGA.

    I could go buy a DP to VGA cable and hope that it would work with that, but why the options do not have a choice of DVI? If possible, please let me know what to do to get this choice.

    Thank you

    Katrina

    Update: ordered another monitor U2414H, but none of the cables provided with this worked. I had to order a cable of DP to DP to connect two monitors. DPout used in the RPI and it works fine now.

    You use IPHOTOS or PHOTOS and what version of the operating system.

    You can have several libraries in IPHOTOS and PICTURES (in the pictures that only your library designated system is synchronized with other devices via ICLOUD).     You can split the libraries of useful information - like a vacation, family events, pictures of your pets.

  • Don't daisy chaining affect results of the assessment?

    I need to split a large file of Captivate 4 project into smaller segments. If I Garland resulting segments, what will happen to evaluating the results since the first segments of one or two. Currently, the results of the evaluation of all the slides appear as a total accumulated after the questionnaire at the end of the tutorial. If I shared the tutorial and daisy chain segments, the total valuation always results will include results of the evaluation of all the blades in the Garland?

    And what happens to the table of contents? All segments of the closed string will have the same table of contents? If so, how would I update the table of contents if I had to?

    If plug you in series a project, then each project will be an instance separated with no communication between them. Basically all assessments, OCD etc will apply to this particular project if you will not be able to get a cumulative total for your contributions in the last chapter.

    If you have access to a Flash programmer, you can create features to store the results of the quiz of each chapter and then bring them all together in the last chapter.

    There is no joy for the table of contents. Maybe you can use the aggregate instead of this function, but the functionality and the level of detail is not the same as the table of contents.

  • Daisy chaining 2 U2414H to Surface Pro 3

    A month ago I bought an i7 Pro 3 Surface and a week ago I bought 2 monitors Dell U2414H more than 2 cables of Startech (HB miniDP2) and DP2DP.  I plugged the miniDP2DP at the entrance of the first monitor and then the DP2DP cable to the output port of the first monitor in the inlet of the second monitor.  I figured that miniDP to the Docking Station is not compatible extension so I plugged it on the Tablet miniDP.

    I can't get the two Dell monitors act as screens 2 and 3. When I select to extend the display, if I disable the DisplayPort 1.2 on the first monitor (via the menu settings-> DisplayPort display-> enable / disable) I can get the screen 3 is a 2 screenshot, but if I put it on Enable, screen 3 is empty.  When I change screen 2 setting back to activate, I get a warning message that I need to make sure that the graphic card supports STD / DisplayPort 1.2.

    I checked the graphics driver and firmware for the monitors and the Surface Pro 3. I tried the two cables provided with the monitors, all to nothing does not.  I called technical support from Microsoft and Dell technical support time and both tell me that their components work fine, it's a problem with it product of another company.

    I've seen several posts on this site but I haven't seen a good response to my problem.  Someone out there who has had this problem and found a solution?

  • U2414H DP 1.2 STD questions

    Hello

    I have exactly the same problem with 3 monitors U2414H.

    P25 User Guide:

    "To allow the connection of STDS, Please use only DP cable such as estimated in the box (or) other DP1.2 certified by cable and change the RFP DP1.2 setting by following the steps below:

    There is no DP > cable DP in the box, only a CDM > DP.

    Cable to connect the DP STD monitor shows the first image can be found in the RFP (NO CDM) of the first monitor.  (Which is the opposite of the connecting cable DisplayPort (Mini-DP DP) black P24)

    The PC is an HP 6300 Pro running an AMD Radeon HD card 7450 DP - it will not detect the monitor as having STD available.

    Do I have to go buy another RFP > RFP cable?

    rod_bunny,
    Our cable should suffice.

    In a monitor three DP MST parameters, only the first and the second monitor in the chain would be DP active 1.2 in the OSD.

    Computer monitor 1
    computer card video DP or CDM on--> monitor 1 DP or CDM in via the Dell mDP to DP cable

    Monitor 1 monitor 2
    Monitor 1 DP 1.2 MST on--> Dell DP to the CDM cable--> Monitor 2 CDM in

    Monitor 2 monitor 3
    Monitor 2 DP 1.2 MST on--> Dell DP to the CDM cable--> Monitor 3 CDM in

    Of course, this assumes that the video card and driver are compatible DP 1.2.

  • Black screen U2414H DisplayPort more low setting applied

    I have a dell precision computer M4800 laptop with docking station and two monitors U2414H.

    * Windows7

    * AMD over-pants M5100 FireGL V

    * I use the supplied cables supplied with the monitor miniDisplayPort

    * The docking station has two output ports DP (video 1 and video 2)

    * I've only tried the miniDisplayPort on the monitor inputs

    * The monitor was purchased through Dell

    A monitor works perfectly well, and works with a cable and either output DP (so I guess that the docking station and the cables are fine).

    However, the other monitor shows a black screen (if his hip as a single monitor or if I try to add the two together).

    Windows displays this warning when it is connected:

    Display applied lower setting port

    "The system has detected a problem with the connection between your computer and the DisplayPort monitor that prevents you to use higher resolutions and/or refresh rate."

    The monitor shows a black screen and is configured with a miniDisplayPort as input Source.

    If I try to bring up the OSD message is displayed:

    "There is no signal from your computer. Press any key on the keyboard or move the mouse to wake him up. If there is no display, place the monitor button now to select the correct input in the on-screen Display menu source. »

    I wasn't able to do a reset to the factory via the OSD settings, but I managed to turn on/off the setting of DisplayPort 1.2 (based on immobilized the Menu for 8 seconds). I tried with both enabled and disabled for the same result.

    Thanks for the answer by Chris,

    That moment everything works, I'm a little hesitant to restart in case something goes wrong again, but for now, everything is good.

    In the end, I did the following:

    * Update the BIOS

    * Set up the BIOS to disable switchable graphics (which means AMD card is used)

    * Updated AMD drivers

    * Uninstalled Dell Monitor driver

    * Plugged the monitors of the docking station, and then ran the driver monitor DELL software - it detected two monitors and installed the software.

    * The things still are not 100% with the questionable monitor - but I changed the parameters of DisplayPort 1.2 and its working now. (If I got to the "display settings" OSD display display Port 1.2 > disable).

    I put the laptop to sleep all night and he works up and all the monitors turned on (yay), but I am yet to perform a reboot since I have things to work.

    I'll close this issue even if things work out right now. Thanks for the suggestions (such as various tests I did based on your suggestions led me through the steps above to make it work).

  • IP in chain - timing problem with Windows 10

    Hello

    I was working on a project and noticed something that I wanted to highlight to others and to see if I could get a reasoning as to why this is happening.

    I started this about four months ago and recently updated my computer to Windows 10 up-to-date project. I am under Labview 2014 V14.0f1 (32 bit) and had not seen any problems with labview until I activated an error logging code which reports data to a syslogger.

    We started noticing that the recorder took much longer than usual to deal with errors and in turn slowed down the whole program.

    When we dug in the question, we found the slow down was the INVESTIGATION period to the block of the string that is used to extract the host name. It took about 4.5 seconds to complete. I have run the same code on a windows 7 VM and it run under a 1 ms...

    No idea why IP chain is taken almost 4 500 x times more time in Windows 10 vs Windows 7? We have worked around the issue by making a control that can be set from a file configuration of the value, but I wanted others to know and hopefully get an answer to why this is the case.

    Thank you

    Chris

    LabVIEW 2014 is not technically compatible with Windows 10.

    Compatibility of the versions of Windows with LabVIEW.

    Maybe the search time is affected by something that has changed to win 10.

  • HP 8440p: DisplayPort to HDMI Audio problem has never been resolved?

    I have a HP 8440p with NVS3100 graphics card. I tried all suggestions get the DisplayPort to pass audio through a DP-HDMI adaptor without success. I even tried to buy several cards in the hope of findingone that worked, even the own expensive adapter from HP.

    I cannot conclude that it is now established that the HP 8440p with the discreet NVS3100 (not the graphics card Intel integraed) simply cannot get audio of the DisplayPort adapter to a HDMI adpter? If the answer is he can't then I start shopping for a new laptop computer with native HDMI and DisplayPort not troublesome.

    Thank you

    Redlyne

    Hey Dude.

    If you want that works = it is confirmed in Windows 7 (x 64) and Windows (x 64) 10 = - and assuming that you have the NVS3100m GPU, all you need to do is to install the older drivers NVIDIA 188.31, file name sp47020.exe and can be found once you go to HP/Support/Drivers on your machine and after selecting either Windows 7 Professional 64 bit as your operating system. This driver also works well to win 10 x 64. It is probabbly not the fastest graphics driver or, after being released in 2010, but at least audio on DP/HDMI works :-) Have fun!

    If not clear, contact me.

  • Daisy chaining with other routers and the common IP range EA6500 V2

    I have a local network of...

    • a modem
    • a gateway connected to the modem computer/server
    • has a modem-router connected to the gateway/server via the port of the gateway/internet
      (gateway/a two server NETWORK interface card)
    • a and B modem router wireless connected to the router via the gateway/router internet port B
    • both A and B using the same set of IP addresses, 192.168.0.XXX

    Now I want to do the same thing with my Linksys EA6500 V2 I did with router B, I want to connect the Linksys router has via gateway/internet port on Linksys.  In addition, I want the Linksys router to use the DHCP server on the gateway server / as everyone is on the local network and, of course, I want to use the series of IP addresses, 192.168.0.XXX.

    What I tried to do is to disable DHCP on the Linksys service, but nothing seems to change once the changes are activated.  I look in the Local network settings and see all the old default 192.168.1.1 for the router address and so on.  I also tried to change the address of the router manually an address of 192.168.0.x and was immediately cut off this subnet.  I tried the renewal of my Windows client computer and couldn't do that either.  And as my client could not change its own address 192.168.1.X, I couldn't reach the router to the address that I gave him.

    How can I set up this router so that it uses the DHCP server on the gateway/server computer, including acquiring its own address in the same series.  Or at least set up so that it uses the same series of address than the rest of the LAN and no longer functions as a separate subnet?

    It seemed that all I had to do to set up router B to connect this way was to disable the DHCP server and everything fell into place, no problem.  Is this all I need to do here?  Am I supposed to restart or something?  I'm tired of guessing and trial and error.

    All tips or hints would be appreciated.

    You have to give the EA6500 a router static IP address in the same subnet as your network, but not in the DHCP range.

    Follow the instructions for 'LAN to LAN' Cascading in the link below:

    In waterfall or connect a Linksys router to another router

    Thing to keep in mind when cascading a router:

    1. Change the IP address of the secondary router to something like 192.168.1.254 so its on the same network, but is not in conflict with the main router
    2. Make sure that the DHCP service is disabled on the secondary router
    3. Make sure that nothing is ever connected to the internet port of the secondary router
    4. Differentiate the wireless SSID by location (Ex: downstairs) and the channel
