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

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

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

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

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

Dear Dell,The Dell U2715H in question presents the Blacklight Bleed very pronounced especially in the lower left and right of the screen, as seen in the photo attached even in light conditions above 150 lux.I hope you help me solve my problem because it is very annoying.

A:Excessive backlight bleed Dell monitor U2715H

The only solution is to have the monitor replaced, assuming it's under warranty.  If it was purchased from Dell, contact customer support and have it replaced.
If it was purchased from a third party, return it to the seller for a refund or replacement.

Hi there. I am working with two monitors. The first is a ViewSonic VX2250wm LED monitor, connected to the desktop (Lenovo ThinkCentre M90p) via a
DVI
(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/
Displayport
adaptor, 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?

Hello:
1) I recently bought a  Dell Precision M4700 that has a Displayport, HDMI and VGA ports.
2) I also bought a Dell monitor U3011 that also has Displayport, HDMI and VGA port.
When I use VGA cable with VGA ports I am able to use dual (laptop screen and U3011).
But I would like to use Displayport to connect the U3011 to laptop. This setup used to work fine until yesterday.
Today I am not able to view/use my U3011 when I connect via Displayport (works fine with VGA).
How can I make laptop detect the U3011? The monitor says "there is no signal".
 
I don't have another laptop or monitor to troubleshoot the issues.
Here is what I did:
1) Upgraded the BIOS to A08
2) Upgraded NVIDIA Quadro K2000M Driver to version 9.18.13.1150
3) Upgrade other device drivers to latest releases.
 
Your help is much appreciated.
 
 

A:No signal Displayport Dell Precision M4700

Hi katari,
If the monitor has driver’s disc, please install the drivers for the monitor.
If you do not have the disk please use this link to install the drivers for the U3011 monitor: http://dell.to/146JzDi
Click the above link, select the operating system, click Download file and install the drivers listed by following the onscreen instructions.
Try changing the input source to DVI by using the monitors “Onscreen display menu”. Refer this link: http://bit.ly/ZLAcno
Also please try a different Display cable to check if the problem is with the cable itself.
Kindly let me now the results.

Nothing shows on the external monitor no matter what I do or try on either the laptop or monitor?  I have tried this on a Dell E7000 series laptop also with no result on that one either?
Does the HDMI port on Dell laptops support video or do I need to utilise some other means of connecting a second monitor.  Bear in mind there is no VGA output on these laptops.

First of all, I would like to appologize since Im not an expert on IT and I dont know most of the technical words to refeer to some things... And so I have my computer at work. I used to love it because it was so fast and I could do plenty of tasks with it at the same time (e.i. listening to music while I translate some docs, searching on internet looking for words, forums, etc.) But last year, it started to reboot/restart by itselft. I realized it happens when I see videos on youtube (but not always), when I check some websites with music or when the website has too much information and pics and similars (for instance, online news websites, official websites, etc.) Last year also, it had a sound coming form the CPU...It was like the ventilator I think, but now not any more. When I ran the examination everything seems fine so I really dont know what is wrong with it... Someone had experience something similar???

A:ThinkCentre M91p motherboard and ECC RAM??

My question goes like this : On a out-of-warranty ThinkCentre M91p, if we replace the standard CPU (i5) with a socket compatible Xeon CPU, will the motherboard support ECC RAM?

No.  It's the Intel Chipset that interfaces to memory, and only workstation and server Chipsets support ECC.  Check the specs for your desktop Chipset if you like. 
 
Also, just because a processor will fit into the socket, does not mean it will be supported by the BIOS.   Sometimes there is overlap between ThinkCentres and ThinkStations which do use Xeons.   If so, that Thinkstation model will be listed on your BIOS download page, but for unknown reasons that upgrade does not always work.

Hello, I cannot find the way to install an AMD FirePro v3900 on a ThinkCentre M91p.I need such board for sharing the desktop between two monitors having a DisplayPort and a DVI and don't have enough time to purchase another board. On the M92p, I can use it by going in the BIOS, set the video settings to "PEG" (PCI-e Graphics Device), enable Multi-Monitor support. The cards works and I can later install the driver (coming with AMD Catalyst) to obtain the possibility extending the desktop to two screens. But on the M91p, it does not work : the screen connected to the PCI Express graphic card reports "no signal" no matter if I connect the display with the DVI or the DisplayPort. I also tried setting the video to "IGD" (Internal Graphics Device) or to "Auto" with the graphic card plugged, but connecting the cable to the M91p's native VGA or DisplayPort, with the hope that I could see something and install the driver for the graphic card. But there is no signal to the native ports when the video card is plugged. I also trid using AMD Radeon cards which were working with ThinkCenter M91p or M92p.One with HDMI+DVI works.One with DisplayPort+DVI doesn't.I need a board with DisplayPort (DP) as most of my screens have DP and no HDMI. The drivers are up to date (including the chipset). Only the BIOS was not updated.Should I update it ? Or does the problem have other origin (e.g. power) ? Thank you very much for your help.

Hello everyone! I've tried upgrading my ThinkCentre M91p with a R7 250X graphics card and a 500W PSU. The graphics card is slightly bigger than the one that came with the desktop, if that information is any helpful. The problem is that the PC turns on, but my monitor doesn't recieve any output. I checked the slots and everything is plugged in as it should be. According to some similar topics, the GPU is too strong for the BIOS. Is there any way to fix this? This is the only graphics card I have. Thank you!

See this recent thread:  Lenovo-m91p-White-List-GPUs
 
M91p BIOS has two modes, UEFI and a compatibility? mode, I suggest you try both.  Also, check that the BIOS setting for the Video Devices is set to [AUTO], or has the Multi-Monitor Support = Enabled.  Otherwise, it may only use the internal graphics, ignoring the card.

Bluetooth is a quickly evolving technology, and to support later devices, you'll need an adapter that supports the latest versions of Bluetooth.    'Newegg' is a good place to look for anything computer related.

I'd recommend going into the UEFI, which replaces the old BIOS standard, and resetting to optimal defaults, which will likely fix the issue. You also should update it, if you have access to a Windows system use rufus to format a bootable dos usb stick and copy the contents of the USB Drive UEFI BIOS Flash Package so you won't need Windows (or a CD) on the actual system to do updates. The current version is 58 vs the 43 you have on there now. By the way you can also use rufus to install Windows to a usb drive for 'Windows To Go' mode which is quite useful at times, especially if you don't want Windows on the system itself. You can download a Windows 10 iso directly from Microsoft's website and via rufus  'Windows To Go' mode isn't limited to just the Enterprise version. CHANGES for 9HKT58A/9HJT58A

This is the last time I buy a "certified refurbished" computer on Amazon !  Also, when I turned the computer back on the fan speed increased. It was getting louder and louder. I thought it was going to explode! Well I repeatedly hold down the power button and unplug the power cord and that's not working. That's what I would do every time my screen froze in the past. The screen would freeze, I couldn't move the mouse either. The light on the desktop is on, I tightened the cord of the monitor to make sure it's connected properly, and the mouse light is still on. The exact desktop name: Lenovo ThinkCentre Premium High Performance M91P Desktop Computer, Intel Core i5 Quad-Core Processor 3.1GHz, 8GB RAM, 1TB HDD, Windows 10 Home (Certified Refurbished) ...and I purchased it on Amazon. I bought this desktop in April of this year and now I don't have product support via amazon anymore. I can't find the serial number on this computer.

Having a hard time finding a part number for the secondary hard drive cage.  This would be the cage that is L-shaped and attaches to the base of the tower.  For now I was able to put the 2nd hard drive in the card reader bay, but would prefer to mount as designed as I'm concerned with the heat associated with one hard drive mounted directly about the other.thanksjoe

A:Secondary hard drive cage for Thinkcentre M91p 4524

Since no one ever answered this, and I have one in front of me...The sticker says the part number is 43N9680The stampings in the metal say 1B03AFY00 REV B and 2G266-01 REV B

I recently (November 2018) purchased the following system through Amazon: 
Lenovo ThinkCentre Premium High Performance M91P Desktop Computer, Intel Core i5 Quad-Core Processor 3.1GHz, 8GB RAM, 1TB HDD, Windows 10 Home (Certified Refurbished) (This is the product description from the Amazon website.) 
 
From the Lenovo support website, their lookup tool gave me the following info specific to my PC:
Serial #: xxxxxxxx
Machine Type Model:  7033A25
 
According to www.datamemorysystems.com the maximum capacity is 16GB.
And the memory type is: 4 x 4GB DDR3-1333 (PC3-10600)  512x64  CL9  1.5v  240pin  DIMM
 
I provide this information for the benefit of others who need this info and to see if anyone disagrees before I go out and buy it.
 
Thanks and good luck,

Here's just a little background info:
(This post is not a complaint.  So far, I'm happy with the PC.  It has a couple of glitches but I expected as much since it's a refurb.)
 
It actually arrived with 7GB RAM and 2TB HDD.  (I guess they traded off 1GB of RAM for 1TB of HDD?) In my experience you always install RAM in pairs or, at least, even numbers.  There are four slots on this machine filled as follows: 2GB+2GB+2GB+1GB.  Just seems odd.
 
When I first booted up the machine I was getting memory errors every five or ten minutes.  It was a pop-up window saying something like "Cannot write data to m... Read more

Hi, acccording to the product specification "Intel HD Graphics in processor, uses main memory, DirectX  11.1, twoDisplayPort, one optional 3rd DP (not support DP to HDMI dongle) or VGA, supports triple independent display;" I should be able to connect my M600 to a TV with a HDMI connection. I have connected one of the two DisplayPorts to a PC monitor (DisplayPort to DVI cable). This works fine. Then I wanted to connect the other DisplayPort using a DisplayPort to HDMI cable to a TV (which has the explicit statement "PC input" on its packaging) but there's no signal according to the TV. Of course I pressed Win+P on the computer several times and selected the corresponding source on the TV. Furthermore, I tried it with the other DisplayPort - same result. Even if I disconnect the monitor use only the TV this does not work. What can I do?

Just got the machine and plan to connect theree monitors. it has two DisplayPorts and one HDMI port in the back. I read conflicting things about DP to HDMI dongles.  Do I need "active" (witth a chip) or "passive" adapters so that I can use all monitors simultaneously? THe answer may be with clarification of whethre the DP ports on the machine are DP or DP+.  Thank you

Hi all - thanks for any help with this:
just bought a new dell monitor U2715H in hopes of adding a second screen to my current system (pretty old XPS 420) Monitor out is DP,  video card in is DVI x2 - old monitor has the first DVI slot - got a DP and to DVI cable and hooked it up, but new monitor not detected anywhere - driver updates of the video card are crashing.
Dell support is not helping despite much trying. do I need a new video card (Radeon HD1600XT) or am I missing something? I realize I'm due for a whole new system but am in the middle of a deadline for a project
thanks for any help!

Hi everyone,
I recently purchased a U2715H 27-Inch monitor, unfortunately I happened to run in some issue that other users here ran into as well. My monitor would flicker for a few seconds presenting a black screen. On top of that it would sometimes go in Power Save Mode, or it would not detect the signal coming from my laptop right away (requiring me to turn it off for a minute, unplug it, replug it and turn it on again).
As you can imagine I immediately replaced it, especially since I noticed that other people had the exact same issue and did the same. Now here's the interesting part, the new monitor that I received seemed to be ok for a few hours but the it started presenting the exact same issues as the old one.
Keep in mind that I tried the following solutions: using a brand new HDMI cable (same issues), using a DP to HDMI adapter (same issues), plugging my laptop into another monitor or tv (no issues), and plugged in my laptop to the same exact monitor but 24" instead of 27" (no issues). So this led me to think that my laptop has no problem whatsoever.
I have a GeForce GTX 960M, which should be more than fine. Now I am not sure what to do, I think this is a great monitor but I am afraid that replacing it would just lead to another defective product. I am inclined to just return it and look for a completely different one.
What do you suggest ?

I have the Dell AC511 soundbar connected to my DEll U2715H monitor.
When I change from DVI input to HDMI Input, the sound dissappears. Or, to be correct the sound remains with my DVI unit even after switching to the HDMI input.
I guess this is a design bug with the monitor as I did not have this problem with my previous monitor, the U2415H.

Hi,
I have a Dell Precision 7510 (Intel HD Graphics 530 & NVIDIA Quadro M2000M). I want to drive 3 external displays (Dell U2715H) off of this machine. What are my options? I have the E-Series Port Replicator, is it doable with that?
Thanks,Sean

A:Precision 7510 with 3x Dell U2715H displays

Yes, it will be doable. You might have to mix and match using both the dock and system (depending on the exact dock series), but it looks like if you use ports on the system you can technically get this setup as long as the switchable graphics are enabled (and it should be). Here is also a link discussing this. I got the info above from internal sources, but you also might see this on the sales/support site. Best regards,Brad

Hello All,I have just purchaced a ThinkCentre M710 Tower with the optional GeForce GT 730 upgrade for graphics. This video card produces no video even after having 2 technicians come out and replace 1) the motherboard and 2) the GeForce video card. I can get video from the onboard Intel graphics from both the VGA and DisplayPort connectors. Changing the BIOS to initate the PEG first makes no difference in video output except to remove the accessability of the BIOS from any port. The system is running Windows 10 PRO.Here are the options installed from Lenovo;ThinkCentre M710 TowerIntel Core i5-7400 3.0G 4CGT730 2GB D5 64b DP HP4GB DDR4 2400 UDIMMTW B250 210W 85%Windows 10 Pro 64Intel 3165+BT 1x1ac HPI was told that a reinstall of Windows 10 is in order? I would think that this should have been tested at the time of the build. 3 monitors have been used by the 2 technicians for testing.Anyone have any information on using PCIe graphics in place of Intel onboard in this unit?Thank you,Scott
